No, he isn't. Statements like this do very little to further your argument. If you want people to stick to facts then it's best to take the lead
I suppose that's fair. Calling him a racist at this point is merely conjecture. Nevertheless, his argument is farse; it's sociological speculation masquerading as scientific inquiry. His understanding of physiology (or bioenergetics, in this particular matter) is nonexistent.
So to answer Lusst's call, here's a cut-to-the-bone primer.
There are three systems by which the body generates energy:
1) The ATP-CP System (aka the Alactic Anaerobic System)
2) The Oxygen-Inependent Glycolytic System (aka the Lactic Anaerobic or Anaerobic Glycolytic System)
3) The Oxygen-Dependent System (aka the Aerobic System)
Siff said:
In general, power and strength rely heavily on the high energy phosphagen system, muscle-endurance on the oxygen-independent system glycolytic system, and cardiovascular endurance on the oxygen-dependent system.
A single maximal muscular contractions characteristic of maximal power development over a period which may last a fraction of a second rely entirely on stored ATP. The process does not increase blood lactate levels and the limitation to continued effort lies largely in the availability of ATP.
After a few seconds, CP is drawn upon to replenish the rapidly dwindling ATP. The CP contribution reaches a peak after 5-7 seconds, during which time oxygen-independent glycolysis is has already commenced. Extraction of energy from the CP system also does not cause build-up of lactate and protons, so the main limitation to continued effort is the availability of the enzyme (creatine kinase) which resynthesizes ATP.
Strenuous exercise lasting approximately 6-30 seconds activates oxygen-independent glycolysis maximally, but appropriate rest intervals will prevent a serious increase in blood lactate. This is the rationale behind the value of interval or fartlek (repeated jog-sprint) running, and interval circuit training with weights or machines...
Oxygen-independent glycolysis reaches its peak after about 30-40 seconds, and after 90-120 seconds its contribution becomes minimal, being replaced by oxygen-dependent glycolysis. This process becomes the dominant energy-producer for all long duration, low intensity activities such as distance running and cycling.
Siff even includes a table that shows the percentiles for energy contribution from each of the three energy systems in different sports.
Swimming
[50m]
ATP-CP= 98%
OIG= 2%
OD= 0%
[100m]
ATP-CP= 80%
OIG= 15%
OD= 0%
[200m]
ATP-CP= 30%
OIG= 65%
OD= 5%
[400m]
ATP-CP= 20%
OIG= 40%
OD= 40%
[1500m]
ATP-CP= 10%
OIG= 20%
OD= 70%
Rugby
ATP-CP= 90%
OIG= 10%
OD= 0%
Basketball
ATP-CP= 85%
OIG= 15%
OD= 0%
Hmmm...a 20-second 50m sprint is 98% dependent on the ATP-CP System...kind of throws out this clown's bullshit theory that "West Africans" don't succeed in swimming because they lack slow-twitch muscle fibers, doesn't it?
And Rugby and Basketball have almost identical energy system demands? Once again, it looks like redneck sociology is the governing philosophy, here.
Like I said, this is ridiculous. Sociological factors have (and always will) play a much greater role than genetic traits in why certain races succeed at certain sports.
And Himalaili (or whatever the fuck your name is): before you go off touting yourself a guru, just go reading
one fucking book.
