DNA testing for sports

Sports performance depends on multiple factors, such as training, nutrition, equipment and advances in training methods. However, a non-negligible proportion of athletic performance depends on genetic factors.

Indeed, your genes have a great influence over components of athletic performance such as strength, power and endurance, flexibility, and neuromuscular coordination. The first noticeable difference between athletes of different specialties is in body morphology (i.e., height and body composition), with specific body types naturally suited to specific sports. However, your genetic makeup runs deeper than what is visible to the eye, as it can explain phenotypes such as muscle fiber size and composition, or injury sensitivity.
