Nature or Nurture in Human Athleticism

In the past, athleticism in humans was the difference between life or death. However, in modern times our athletic ability is less about survival and more about performing well in sports. There is a debate about whether athletic ability is from our genes or from training. This is one part of the nature nurture debate. While both our genes and training is responsible for our athletic ability, our genes are more important to deciding our athletic ability.

Genes can determine many aspects of our athletic ability. According to the New York Times, “there are many genes that determines your baseline ability and your improvement speed” (Aschwanden). Using sprinting as an example, the article says that some …show more content…

It suggests that genes will make it much more difficult for some people to achieve the same performance as other people. Sprinting speed is dependent on fast twitch muscles. The ratio of fast twitch muscles to slow twitch muscles is one component of how professional sprinters are so fast. Sprinters need to “have at least 70 to 80 percent fast twitch muscle fibres” in order to be successful, compared to the global average of 50 percent. (Kelland). The percentage of fast twitch muscles are completely dependent on the genes, and although one can train to increase the amount of muscle, the percentage will still stay the same. Additionally, scientists have found a gene called ACTN3 that can give “extra power to fast twitch muscles” (Kelland). There are variants of the ACTN3 gene that can influence running speed and endurance. However, despite scientists finding such a gene, they also state that “ACTN3 doesn’t tell you whether or not …show more content…

As stated in the second paragraph, our genes determine both our baseline athletic ability and also our rate of improvement. According to the New York Times, “After months of identical training, some exercisers make almost no fitness gains, while others increase their aerobic capacities by 50 percent or more” (Aschwanden). Some people may argue that although our baseline abilities may be different, training will help us all improve our athleticism. However, although this is the case, there is much more to be considered. Although training will improve one’s athletic abilities, we cannot control the speed at which we improve compared to others, the amount of effort needed to achieve the same results as well as the ceiling in which we can no longer improve. Because our bodies all react differently to training, the people that respond slower to training will need to train more in order to reach the same results. Along with training, our bodies also have different rates of metabolism, so some people may also need to work harder to control their diets. There are many factors in athleticism that are out of our control and our athletic ability relies more on our genes than on
