Aerobic Performance

Aerobic Performance 

Interesting studies have shown that certain genes control how we perform in aerobic exercises, such as running or swimming. Having a bigger lung capacity or VO2 max means you'll generally have a more comfortable experience and better aerobic fitness. This is because your lungs will be able to take up use more oxygen in one minute. These studies have shown that certain genes actually influence our lung capacity. For example, certain variations of genes  like RBFOX1 or were related to a bigger lung capacity, while others like NFIA were associated with a smaller lung capacity. Age also has an influence in addition to our genes, since our lung capacity beginning to decrease around the age of 30. So, a young  soccer player with a gene contributing to a greater lung capacity is likely to experience less shortness of breath and better endurance than someone older with an opposing genetic variation.  

Exercise Aversion


Studies have found that our level of motivation for exercising is partly influenced by our genes. So how your body physically holds up during a workout and how you mentally respond to the challenge both come down to your DNA.
Certain variations of genes like LEP or SGIP1 were found to be associated with a greater motivation to exercise. But, certain others like LEPR were found to be related to less motivation for exercise. These studies indicated that up to 50% of our like or dislike for exercise is due to these genes. But don't confuse Exercise Aversion with a lack of motivation. Exercise Aversion is stronger than a simple lack of motivation since it has a genetic basis. People who have a genetic variation that contributes to Exercise Aversion will have less of a desire to exercise, and it might even be their least favourite activity.
