Retro Walking







I WAS sitting at a desk in the office today watching a pair of Canada Geese on their walkabout around the parking lot—their parking lot—as it would seem they have now claimed it as their own. 

And as I stared out the window, thinking of things related and not, a figure slipped into my peripheral vision: a young girl walking backwards along the wall of the building opposite. 

She wasn't pacing. She wasn't talking on the phone or to herself, and her neutral expression did not appear as that of one in debate of whether or not to enter the building. She was simply walking backwards over and over again.


So ... as one does when one is curious about such things, I turned and Googled (is 'googled' an acceptable verb yet?), “Why do people walk backwards?” And after a finger tapping pause of 0.65 seconds, over 15, 000, 000 postings on the subject appeared miraculously on the computer screen before me.

Turns out, backwards walking/running is a form of exercise called ‘retro walking/running’. And from what I read, it is believed to have many benefits over conventional … say … forward walking/running?


WHAT FOLLOWS ARE A FEW OF THINGS I LEARNED TODAY ABOUT RETRO WALKING/RUNNING:


  • They can be dangerous activities to partake in: It is much more difficult to brace a backward fall or drop into a roll if one trips. [1]  (worth stating only because I found it mentioned, repeatedly)




  • There is an Australian film about backwards running called Reverse Runner.


  • Backward walking is said to have its origins in ancient China where it was practiced to promote balance and good health. [2]

  • “China’s ancient Mountain and Sea scripture records the exploits of an itinerant immortal who could walk backward faster than the eye could see. Walking backward has been popular ever since. The movement exercises muscles that are not used in ordinary walking, especially in the back, waist, thighs, knees and lower legs. Some people believe walking backwards is akin to a karmic reverse, allowing you to correct mistakes and sins of the past. A version of the walking backward exercise is the walking-backward-while-rolling-magnetic-balls-around-your-hands movement. The magnetic balls electro-magnetically massage acupuncture points in the palms and give aging wrists good exercise.” [3]


  • Walking backwards puts less strain and requires less range of motion from your knee joints. [2]


  • Walking backwards for just 10-15 minutes, four days a week for four weeks has been shown to increase flexibility in your hamstrings. [2][4]


  • When you walk backwards, your heart rate tends to rise higher than it does when walking forward at the same pace. [2]

  • In one study, women who underwent a six-week backward run/walk training program had a significant decrease in body fat as well as improvements in cardio-respiratory fitness at the end of the study. [2][5]


  • Backward locomotion improves the functions of our cerebellum which coordinates and balances our bodily movements. [9]


  • Backward running requires close to 30% more energy than running forward at the same pace,[2][7]  and puts less impact on your knees. [2][8]

  • "As in a catapult, muscle-tendon units are stretched more slowly during the brake at the beginning of stance and shorten more rapidly during the push at the end of stance. We suggest that the catapult-like mechanism of backward running, although requiring greater energy expenditure and not providing a smoother ride, may allow a safer stretch-shorten cycle of muscle-tendon units." [2][8]


  • The muscles of the front and back of the shin and ankle are strengthened, owing to the increased strain of performing an unfamiliar exercise. [9]


  • Backward running can result in: [10]
  • A more erect posture during performance
  • Recovery and strengthening from hip joint injuries
  • Recovery from groin injuries
  • Recovery from hamstring injuries
  • Knee joint surgical rehabilitation
  • Alleviation of shin splint syndrome
  • Recovery from Achilles' tendon injuries
  • Recovery from ankle sprain injuries

FIN




(And now with this backwards walking/running business all cleared up, I can focus on trying to get the Tame Impala ear-worm out of my head.)

Apple







THE HUMBLE APPLE: the namesake of celebrity offspring; the bruised red fruit children dread finding at the bottom of their Halloween candy bag (and not just because of the threat of concealed razor blades); the ingredient of pies and sauces and juice; the things hurled at Dorothy in Wizard of Oz










THEY are bobbed for; or they used to be. (Do kids still do that?)

British author W. H. Davenport Adams describes the bobbing game as it existed around the turn of the 20th century in his 1902 book, Curiosities of Superstition: [1]



“[The apples] are thrown into a tub of water, and you endeavour to catch one in your mouth as they bob round and round in provoking fashion. When you have caught one, you peel it carefully, and pass the long strip of peel thrice, sunwise, round your head; after which you throw it over your shoulder, and it falls to the ground in the shape of the initial letter of your true love's name.”




THEY are packed in school lunches, left on teacher's desks and picked by the bushel on family outings in the fall. 

We are told they are nature's toothbrush; told that eating one a day will keep the doctor away.




THEY are ... (perhaps strangely) ... one of the haunting images that lingered with me after reading In Cold Blood: Of Mr. Clutter, with his good strong set of white teeth, crunching on apples.
“Once, he went out to the kitchen and came back with two apples; he offered one to me, but I didn't want it, so he ate them both. He had very white teeth; he said apples were why.” [2]




THEY are symbolic of innocence lost, and of that which is forbidden; of sin and seduction, redemption, knowledge, love, beauty, cunning, good fortune and of course, Eureka! Moments, cue Sir Isaac:








From the ROYAL SOCIETY website [3]

The most famous anecdote of discovery in science is how Newton’s apple inspired the notion of gravity as a universal force. In 1752, William Stukeley set down the story in his manuscript, Memoirs of Sir Isaac Newton’s life, as it was told to him by Newton himself:
“Why should that apple always descend perpendicularly to the ground, thought he to himself, occasioned by the fall of an apple, as he sat in contemplative mood.”


One reputed descendant of 
Newton's apple tree at Trinity 
College, Cambridge [4]



SO why all this rambling on about 'dem' apples?

Because I recently read that genetically engineered 'Arctic Apples' have been approved for sale in Canada and the U.S. And no, it was not the mere fact that GMO apples have been approved for sale that got my attention. It was the reasoning behind the modification: Apples with flesh that doesn't brown when exposed to air.


  • Is this really necessary?  
  • Have dramatic apple eating pauses become a thing?
  • When did it become problematic for us to eat an apple before it turns brown? 

And if it is a problem, say if you’re baking, (perhaps?) is not a squeeze of fresh lemon sufficient to prevent browning from happening?

And even if, horror of horrors, an apple does start to turn brown, that doesn't mean it’s gone off ... does it? Because I'm pretty sure I've eaten slightly browned apple flesh before, and clearly I've lived to tell. My kid brain had always equated apple browning to how the bread of my PB&J would crisp up a bit if air seeped into the Ziploc (as in, not a big deal!); as opposed to say, the acknowledged hazards of drinking the chunky milk of my college days (the milk that floated to the top of my coffee like plastic snowflakes).

Forget about my chunky college milk; clearly if they've gone and done this with the apples it must be for reasons beyond mere aesthetics. And if so ... My god! It’s a wonder I survived my childhood, what, with the humble apple alone posing so many threats: concealed razor blades, pried out baby teeth, bobbing related hypothermia or drowning, head injuries from orchards; and now we can add to that list (because it had never occurred to me before) callously placed time limits on our lingering second bite. 

Just who do these non-GMO apples think they are?

Fortunately, we can now all breathe a little easier, comforted in the knowledge that browning apples have been eliminated from the list of worries keeping us awake at night.

Okay, okay, I'll rein in the sarcasm. As with most things in life, there are various perspectives from which one can view this, or any story. Perspectives which may force me to, if not eat my words, perhaps, partake in a piece of humble apple pie.


AS I mentioned above, Arctic Apples have been genetically engineered not to brown when sliced or eaten.

This non-browning trait was developed and patented by Okanagan Specialty Fruits Inc. (OSF) based in Summerland B.C., Canada.

The process involves adding a ‘silencing’ gene sequence into the cultivar’s DNA, thereby turning down the expression of polyphenol oxidase, which, in turn prevents the fruit from browning.[5][6][12]

After a three year review, The Canadian Food Inspection Agency and Health Canada have approved Arctic Apples for commercial sale in Canada.

According to Health Canada, the Arctic Apple "is safe for consumption, still has all its nutritional value and therefore does not differ from other apples available on the market." [9]

This announcement followed the U.S. Food and Drug Administration approval of Arctic Apples. 

In a press release, Neal Carter, co-founder of OSF said:[9]
"We are pleased that the FDA has completed their consultative review of our first two Arctic Apple varieties, and their conclusion that they are as safe and nutritious as their conventional counterparts is gratifying and should give consumers full confidence in the healthfulness of Arctic Apples."  

Cited on the Arctic Apples website under 'benefits of a non-browning apple': [7]

  • Arctic apples have more eye appeal: no yucky browning
  • Arctic apples have more mouth appeal: more of the apple’s natural flavor shines through
  • Arctic apples have more nutritional appeal: our health-supporting antioxidants aren’t burned up by a browning reaction
  • Arctic apples have health appeal: without the yuck factor, more apples get eaten, promoting your better health and healthier weight
  • Arctic apples have pocketbook appeal: when more apples get eaten, fewer apples get thrown away



SO, just what is that, 'yucky browning' they are referring to? [8]

Enzymatic browning is a chemical process catalyzed by the enzyme polyphenol oxidase (PO).

In the presence of oxygen, PO catalyzes the first steps in the biochemical conversion of phenolics to produce quinones, which undergo further polymerization to yield dark, insoluble polymers referred to as melanins. 
These melanins form barriers and have antimicrobial properties which prevent the spread of infection or bruising in plant tissues. Plants, which exhibit comparably high resistance to climatic stress, have been shown to possess relatively higher polyphenol oxidase levels than susceptible varieties. 
The reaction is not only dependent on the presence of oxygen, but also on the pH. The reaction does not occur at acid (pH <5) or alkaline (pH >8) conditions. [8]
  
Several methods can be applied to avoid enzymatic browning. These include: [8]
  • Blanching
  • Refrigeration / Freezing
  • Change pH
  • Dehydration
  • Irradiation
  • High pressure treatment
  • Addition of inhibitors
  • Ultrafiltration
  • Treatment with supercritical carbon dioxide (SC-CO2)

The prevention and control of enzymatic browning is one of the most important issues in the food industry, as browned fruits and vegetables are likely to be perceived by consumers as spoiled. [8]


CANADIAN apple sales (domestic & export) have been in steady decline over the past decade. Some apple growers, like Okanagan Specialty Fruits Inc., believe this is due (in large part) to perception: we eat (and thus make our purchasing decisions) with our eyes.

It therefore stands to reason that the eyes and wallets of consumers would be more receptive to packaged/prepared non-browning apples on their grocer's shelves. [12]

The hope, presumably, is that the change will do for apples what it did for those wee baby carrots—you know, because all that peeling and cutting, who needs it! (Though, personally, I find there is a whole world of difference in taste between those wee stubby orange critters and the wonky gnarled carrots plucked whole from the ground. Then again, maybe my taste buds are wired for nostalgia.)

The B.C. Fruit Growers’ Association and the Fédération des producteurs de pommes du Québec have expressed their opposition on the basis of the potential confusion these products may pose to the consumer.[12] (In Canada labeling of GMO products is voluntary) 

Their concerns are not without merit.

In 1989, when the program 60 Minutes aired a story about the use of the controversial ripening agent Alar on apples, the apple market crashed. [12]



Daminozide (Alar) — was a chemical sprayed on apples to regulate growth and to prevent them from falling off the trees before they were ripe. This ensured they were red and firm for storage. In 1989 Alar was voluntarily withdrawn by the manufacturer after the U.S. Environmental Protection Agency proposed banning it based on concerns about cancer risks to consumers. [10][11]


Okanagan Specialty Fruit's Neal Carter says the comparison with Alar is unfair and unrelated. [12]
“The Arctic apples have been through a rigorous review and found to be safe. We’ve been very open and transparent about the product.” 

On the subject of safety, it is perhaps worth mentioning here that the only apple native to North America is the crab apple. [14]  

And that, apple trees of the yummy variety were brought to North America by European colonists in the 17th century. [13]

And that since the complexities of apple genetics (some 57,000 genes), makes growing trees from seeds unpredictable, the current practice for commercial orchards is to propagate apple trees by cloning; usually by grafting a new stem from an existing tree onto rootstock. [12]

As Carter notes: [12]
“Without human intervention, there would be essentially no edible apples growing in North America.”  



I DON'T KNOW. I guess if, big picture, this means more people will eat more apples because they are packaged / presented in a more appetizing way and will thus consume a source of antioxidants which might otherwise be lost on account of that nasty browning (the apparent bane of the slow apple eater's existence); and if this helps the economy and breathes life into a dwindling agriculture sector; then, perhaps this is ultimately a good thing, yes? 

Though as someone who never stopped buying apples; one who is not much bothered by bruising and browning; one who possibly deprives herself (or perhaps not) of all nutritional value by slathering apple slices in honey and cinnamon, I think I’ll just stick to the good old fashioned McIntosh: apple of my childhood; apple of my mom’s and her mom’s homemade apple pies; apple I traveled to orchards to pick with them both as a child; and apple I no doubt stuck my head into an icy bucket of water to pluck out with my teeth once upon a Halloween.

That said (and this is not to comment either way on the merits of GMO foods—though, I'm feeling we have strayed far, far away from altruism with this particular application), I would indeed lament the day I walked into my local grocer to find that this new variety of apple has replaced my old favorite, the misshapen and marred and calloused and bruised all over McIntosh.

CHAMPS







So, last weekend I watched the above documentary called Champs. It profiled the boxing careers of Mike Tyson, Evander Holyfield and Bernard Hopkins. It was in some ways inspiring, and in many ways troubling and profoundly sad. This isn't one of those Rah! Rah! Sports docs that leave you feeling pumped and racing for the gym or to the sign-up board of your local rec. centre with naïve (or perhaps not) ambitions of reaching the highest echelons of athletic stardom. For me, this doc was more of a cautionary tale. A cautionary tale and a testament to the necessity for improved regulations in professional boxing.

Boxing is not alone in the doorway it offers out of adverse circumstances for those with enough talent and drive to follow their dreams down the Yellow Brick Road that leads to Oz.

Blinded by the bright Vegas lights, the glitz, the celebrities, the endorsement deals, the million dollar paycheques, it is easy to get caught up in the spectacle of it all; to become detached from what is really happening in the ring when iron fist meets fragile bone.

A KNOCK OUT ... HE KNOCKED HIM OUT, COLD.

Considering what those words actually mean, we tend to speak them rather casually, don’t we? He knocked him out cold. What a dreadful thing that is to say when you take a moment and really consider the meaning behind the words. 

Would any dollar figure be enough to entice you into the ring with Tyson in his prime? 

Or phrased another way: Would any dollar figure be enough to entice you to bungee jump off a highway overpass knowing in advance the cord was a wee bit too long … not quite ‘splat’ too long but definitely ‘asphalt impact’ too long?


ADVERSITY AS MOTIVATION, DRIVE, DETERMINATION, DISCIPLINE & THE DISTORTION OF FAME

The following are some random para-quotes (I'm not an apt stenographer), trivia, notes & stats I hurriedly jotted down while watching Champs: (In reference to the rules and regulations etc., keep in mind this is a documentary about professional heavy weight boxing in America.)

  • “It is human nature to be fascinated by violence, that’s what sells; that's why boxing sells.”


  • "You want to see how strong someone is? It’s not about putting him in the ring with Tyson; it’s about how he deals with disappointment.”


  • “Who is standing opposite you in the ring is irrelevant; to the boxer it is internal, mental: the drive is to annihilate the opponent.”


  • “I was trained to be a fighting machine, fueled by desire and craving for adoration; and then ... from 300 million dollars to chapter 11.”


  • “It is an unforgiving sport, in more ways than one, the rise and the almost inevitable fall.” 



  • Evander Holyfield lost over 15 pounds of body weight during his 1986 15 round bout against Muhammad Qawi.
  • (After the match he had to be rushed to the hospital where it took over 2 gallons of IV fluids to rehydrate what he had lost during the match.)



  • In America there is no minimum salary for boxers.
  • There has been no implementation of the ‘Ali Act’.
  • There is no league.
  • There is no union.
  • There is no standardized health and safety criteria.
  • It is not regulated like other pro-sports.


  • When the brain is slammed against the back of the head with the intensity and for the duration as occurs during these matches, a concussion can result which can cause swelling and long term hematomas, memory loss, strokes, aneurysms and vessel breakage ...
  • A single MRI is given to a boxer to gain his license. No follow ups are required by law.



AFTER watching the documentary, I did a bit of curiosity inspired reading up. It goes without saying that the subject of boxing could fill volumes. That said, the focus of this entry is very narrow in scope. Specifically, the curiosity inspired reading I did was on the history of boxing regulations; as well as, on the long term impacts of those repeated hits to the head boxers endure over the course of their careers. 

Each aspect, though different - past and present - share a common thread in that they respectively demonstrate how successive generations have modified their willingness to accept extraordinary measures of bodily harm in sports. Knowledge is undoubtedly a good thing, but it's ultimately what we do with the knowledge we gain that defines who we are both presently and in the eyes of future generations



RULES AND REGULATIONS



1) That a square of a yard be chalked in the middle of the stage, and on every fresh set-to after a fall, or being parted from the rails, each Second is to bring his Man to the side of the square, and place him opposite to the other, and till they are fairly set-to at the Lines, it shall not be lawful for one to strike at the other.

2) That, in order to prevent any Disputes, the time a Man lies after a fall, if the Second does not bring his Man to the side of the square, within the space of half a minute, he shall be deemed a beaten Man.

3) That in every main Battle, no person whatever shall be upon the Stage, except the Principals and their Seconds, the same rule to be observed in bye-battles, except that in the latter, Mr. Broughton is allowed to be upon the Stage to keep decorum, and to assist Gentlemen in getting to their places, provided always he does not interfere in the Battle; and whoever pretends to infringe these Rules to be turned immediately out of the house. Every body is to quit the Stage as soon as the Champions are stripped, before the set-to.

4) That no Champion be deemed beaten, unless he fails coming up to the line in the limited time, or that his own Second declares him beaten. No Second is to be allowed to ask his man’s Adversary any questions, or advise him to give out.

5) That in bye-battles, the winning man to have two-thirds of the Money given, which shall be publicly divided upon the Stage, notwithstanding any private agreements to the contrary.

6) That to prevent Disputes, in every main Battle the Principals shall, on coming on the Stage, choose from among the gentlemen present two Umpires, who shall absolutely decide all Disputes that may arise about the Battle; and if the two Umpires cannot agree, the said Umpires to choose a third, who is to determine it.


7) That no person is to hit his Adversary when he is down, or seize him by the ham, the breeches, or any part below the waist. A man on his knees is to be reckoned down.


THESE 7 RULES WERE EVENTUALLY EXPANDED TO:

1) That the ring shall be made on turf, and shall be four-and-twenty feet square, formed of eight stakes and ropes, the latter extending in double lines, the uppermost line being four feet from the ground, the lower two feet from the ground. That in the centre of the ring a mark be formed, to be termed a scratch; and that at two opposite corners, as may be selected, spaces be inclosed by other marks sufficiently large for the reception of the seconds and bottle holders, to be entitled "the corners."

2) That each man shall be attended to the ring by a second and a bottle-holder, the former provided with a sponge, and the latter with a bottle of water. That the combatants, on shaking hands, shall retire until the seconds of each have tossed for choice of position; which adjusted, the winner shall choose his corner according to the state of the wind or sun, and conduct his man thereto, the loser taking the opposite corner.

3) That each man shall be provided with a handkerchief of a colour suitable to his own fancy, and that the seconds proceed to entwine these handkerchiefs at the upper end of one of the centre stakes. That these handkerchiefs shall be called "the colours;" and that the winner of the battle at its conclusion shall be entitled to their possession, as the trophy of victory.

4) That two umpires shall then be chosen by the seconds to watch the progress of the battle, and take exception to any breach of the rules hereafter stated. That a referee shall be chosen by the umpires, to whom all disputes shall be referred; and that the decision of this referee, whatever it may be, shall be final and strictly binding on all parties, whether as to the matter in dispute or the issue of the battle. That the umpires shall be provided with a watch, for the purpose of calling time; and that they mutually agree upon which this duty shall devolve, the call of that umpire only to be attended to, and no other person whatever to interfere in calling time. That the referee shall withhold all opinion till appealed to by the umpires, and that the umpires strictly abide by his decision without dispute.

5) That on the men being stripped, it shall be the duty of the seconds to examine their shoes and drawers, and if any objection arises either as to insertion of improper spikes in the former, or substances in the latter, they shall appeal to their umpires, who, with the concurrence of the referee, shall direct if any and what alteration shall be made.

6) That both men being ready, each man shall be conducted to that side of the scratch next his corner previously chosen; and the seconds on the one side, and the men on the other, having shaken hands, the former shall immediately return to their corners, and there remain within the prescribed marks till the round be finished, on no pretence whatever approaching their principals during the round, on penalty of losing the battle.

7) That at the conclusion of the round, when one or both of the men are down, the seconds and bottle-holders shall step forward and carry or conduct their principal to his corner, there affording him the necessary assistance, and that no person whatever be permitted to interfere in this duty.

8) That at the expiration of thirty seconds (unless otherwise agreed upon) the umpire appointed shall cry "time," upon which each man shall rise from the knee of his bottle-holder and walk to his own side of the scratch unaided, the seconds and bottle-holders remaining at their corners; and that either man failing so to be at the scratch within eight seconds, shall be deemed to have lost the battle.

9) That on no consideration whatever shall any person be permitted to enter the ring during the battle, or till it shall have been concluded; and that in the event of such unfair practice, or the ropes and stakes being disturbed or removed, it shall be in the power of the umpires and referee to award the victory to that man who in their honest opinion shall have the best of the contest.

10) That the seconds and bottle-holders shall not interfere, advise, or direct the adversary of their principal, and shall refrain from all offensive or irritating expressions, in all respects conducting themselves with order and decorum, and confine themselves to the diligent and careful discharge of their duties to their principals.

11) That in picking up their men, should the seconds or bottle-holders wilfully injure the antagonist of their principals, he shall be deemed to have forfeited the battle, on the decision of the umpires or referee.

12) That it shall be "a fair stand-up fight," and if either man shall wilfully thrown himself down without receiving a blow, he shall be deemed to have lost the battle; but that this rule shall not apply to a man who in a close slips down from the grasp of his opponent to avoid punishment.

13) That butting with the head shall be deemed foul, and the party resorting to this practice shall be deemed to have lost the battle.

14) That a blow struck when a man is thrown or down, shall be deemed foul. That a man with one knee and one hand on the ground, or with both knees on the ground, shall be deemed down; and a blow given in either of those positions shall be considered foul, providing always, that when in such position, the man so down shall not himself strike or attempt to strike.

15) That a blow struck below the waistband shall be deemed foul, and that, in a close, seizing an antagonist below the waist, by the thigh or otherwise, shall be deemed foul.

16) That all attempts to inflict injury by gouging, or tearing the flesh with the fingers or nails, and biting shall be deemed foul.

17) That kicking, or deliberately falling on an antagonist with the knees or otherwise when down, shall be deemed foul.

18) That all bets shall be paid as the battle-money after a fight is awarded.

19) That no person on any pretense whatever shall be permitted to approach nearer the ring than ten feet, with the exception of the umpires and referee, and the persons appointed to take charge of the water or other refreshment for the combatants, who shall take their seats close to the corners selected by the seconds.

20) That due notice shall be given by the stake-holder of the day and place where the battle-money is to be given up, and that he be exonerated from all responsibility upon obeying the direction of the umpires and referee; and that all parties be strictly bound by these rules; and that in future all articles of agreement for a contest be entered into with a strict and willing adherence to the letter and spirit of these rules, and without reserve or equivocation.

21) That in the event of magisterial interference, it shall be the duty of the umpires and referee to name the time and place for the next meeting, if possible on the same day.

22) That should the event not be decided on the day named, all bets shall be deemed void, unless again declared on by mutual agreement: but that the battle-money shall remain in the hands of the stake-holder till fairly won or lost by a fight, unless each party shall agree to withdraw his stake.

23) That all stage fights be as nearly as possible in conformity with the foregoing rules.


AND THEN, IN 1867, CAME THE INTRODUCTION OF:


1) To be a fair stand-up boxing match in a twenty-four foot ring or as near that size as practicable.

2) No wrestling or hugging allowed.

3) The rounds to be of three minutes duration and one minute time between rounds.

4) If either man fall through weakness or otherwise, he must get up unassisted, ten seconds be allowed to do so, the other man meanwhile to return to his corner; and when the fallen man is on his legs the round is to be resumed and continued until the three minutes have expired.

IN GENERAL, (& in addition, where not redundant, to the established rules above) today’s professional boxers are prohibited from: [1]
  • Hitting their opponents in the back (neck and kidneys) and below the belt.
  • From holding, tripping, pushing, biting, spitting, kicking, head-butting, or hitting with any part of the arm other than the knuckles of a closed fist.
  • From holding the ropes for support when punching, holding an opponent while punching, or dropping below the waist of your opponent.


The Muhammad Ali Boxing Reform Act, commonly referred to as the 'Ali Act', is a federal law that was enacted on 26 May 2000 by the 106th U.S. Congress to:

1.) Protect the rights and welfare of boxers
2.) Aid state boxing commissions with the oversight of boxing and
3.) Increase sportsmanship and integrity within the boxing industry

The Act amends the 1996 Professional Boxing Safety Act.[5][6]




BOXING RELATED HEAD INJURIES


“Each punch creates a concussion (technically defined as any head injury that causes a disruption of neurological function), and each concussion brings the boxer closer to a state of darkness.”
The bodies’ electrolytes (Na+, K+, Ca+) are responsible for conducting impulses along neurons. Blows to these nerves cause an electrolyte imbalance (exit K+, enter Ca+) which the body works hard to restore. The damage is cumulative, with each successive blow making it more difficult for the body to correct the imbalance. 
"After a brain injury, the heart must supply sufficient blood flow for the brain to repair itself. If the demand outweighs the supply the brain then shuts down and leads to an eventual loss of consciousness," says Anthony Alessi, M.D., a neurologist and ringside physician for the Connecticut State Boxing Commission. "That's when I know to end the match, because if we keep going the fighter is going to die." 

DEMENTIA PUGILISTICA (DP) is a neurodegenerative disease which occurs in athletes having suffered repetitive blows to the head. It manifests as dementia, or declining mental ability, problems with memory, and Parkinsonism, or tremors and lack of coordination.[8][9] It can also cause speech problems [9] and an unsteady gait.

Patients with DP may be prone to inappropriate or explosive behavior and may display pathological jealousy or paranoia.[9]

Sufferers may be treated with drugs used for Alzheimer's disease and Parkinsonism.[10]

Loss of neurons, scarring of brain tissue, abnormal accumulation of cerebrospinal fluid in the ventricles of the brain and damage to the cerebellum are implicated in the syndrome.[11]

Increased exposure to concussions and sub-concussive blows is regarded as the most important risk factor, which can depend on the total number of fights, number of knockout losses, the duration of career, fight frequency, age of retirement, and boxing style.[12]

Depending on the force of the blow to the head, damage may also result in injury to the retina: retinal detachment, &/or retinal hemorrhage. [13]


AS AN ASIDE: (Because invariably someone will raise the point, I am not disregarding the following stats, just focusing on boxing for now ... because I happened to watch that documentary last weekend.) 

The following sports/recreational activities represent the categories contributing to the highest number of estimated head injuries treated in U.S. ER's in 2009. [18]

  1. Cycling: 85,389
  2. Football: 46,948

  18. Roller and Inline Skating: 3,320
  19. Ice Skating: 4,608


ACCORDING TO the Journal of Combative Sport, from January of 1960 to August of 2011, there were 488 boxing-related deaths. The journal attributes 66% of these deaths to head, brain or neck injuries; one was attributed to a skull fracture. [18] 
Boxing may account for fewer deaths than some other sports but the numbers of boxers suffering brain damage are believed to be much higher than recorded. [13]
 The American Association of Neurological Surgeons suggest that as many as 90% of boxers sustain a brain injury over the course of their careers. [13]

ATHA et al. (1985) designed an instrumented padded target mass suspended as a ballistic pendulum to determine the mechanical properties of a boxing punch. Data were gathered from a world ranked British Professional heavyweight Frank Bruno. The target was a cylindrical metal mass of 7 kg. Within 0.1 second of the start, Bruno’s punch had traveled 0.49 m and attained a velocity of 8.9 m/s on impact. The peak force was 0.4 ton on impact and was attained within 14 milliseconds of contact. This represents a blow to the human head of about 0.63 ton. The impulse accelerated the target head at the rate of 520 m/s2 . [14]
In other words, a 6 kg padded wooden mallet, swung at 20 mph would deliver an equivalent blow.


The following excerpts are from Sports Medicine and the Ethics of Boxing: [15] (Some points have been paraphrased.) 

Conceding that much research still needs to be done before we can know with certainty the nature of boxing injuries, it is safe to say that human anatomy is at odds with the preferred tactic in boxing, which is to strike the opponent's head.
This returns us to the issue of what precisely sport physicians ought to do. All sports represent a compromise in personal freedom and safety between the need to pursue enjoyable and lucrative activities and the need to avoid injury.
Unfortunately, refinement of diagnostics and improved education of boxers, trainers, and ringside doctors will take us only so far. What will persist is the boxer's underlying goal: the contest often goes to the boxer who can punch the opponent into submission or unconsciousness.
In matches based on points, the decision often goes to the boxer who excels in aggressiveness and injures or knocks down the opponent through punches to the head.
In professional boxing, the incentive is direct: the scoring and ranking system gives priority to the fighter who is able to knock the opponent out. (The authors note here that the differences between amateur and professional boxing vary by country.)
Even in amateur boxing, where the knockout is less common, there is still a risk of concussion from blows to the head. Hence, in amateur or professional boxing, what would reform ultimately involve? Would the fight need to be stopped after each punch to diagnostically assess the trauma?

The authors suggest that perhaps the foremost way in which boxing related health risks may be reduced is to introduce changes to the rules that would, “penalize punches to the head.”

Seems obvious enough, right?
