Gene of the Day

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.
