Document Summary
Athletic success is complex combination of alleles, experience, and training. Alleles genetics maybe 60% of ability: basic aerobic/anaerobic ability, explosive strength, trainability, body type, athletic ability is polygenic, nutrition, motivation, high vs low altitude. Training experience: as part of culture, explicit in a training program. Hard to find any one unique to any group. 100m, athletes born in usa or caribbean islands of east african ancestry have won 10 of 13 olympic titles distance running events are dominated by runners of east african origin, particularly those from kenya and ethiopia, particularly kalenjin tribes. Gene actn3- one of the only 2 genes to be directly connected to athletic performance that have been extensively studied; data are complicated. Gene actn3- codes for a protein involved in muscle contraction. Provides info for if the muscle is fast twitch or slow twitch (endurance) Provides part of the explosive strength in muscle contraction. Is involved in anaerobic muscle contractions-high strength, high fatigue: sprinting; weight lifting.
