Endurance or sprinting – what suits you best?

Sprinter leaving on the running track.

Our unique genetic profile can make some of us more suitable for endurance activities, others for more intense sprinting activities or power training.

Genes involved in ‘endurance type of activities’ minimize muscle fatigue during prolonged period of mild to moderate intensity exercises, while genes involved in ‘sprinting’ relate to power, rapid bursts of energy and optimum energy utilisation for activities of shorter duration. Depending upon the expression of Endurance/ Sprinting genes a person is categorized as adaptive for either of these.

There are two different types of muscle fibres which are important for these activities, each type being regulated by specific genes. Type I or slow twitch muscle fibres are mainly responsible for improving endurance. In contrast, Type II or fast twitch muscle fibres allow us to perform rapid, high intensity exercises.

It is a proven fact that regular exercise assures health benefits and improves your fitness level. It is noteworthy that genes determine your adaptability for the type, intensity and duration of activity (endurance/sprinting) based on your capacity for aerobic metabolism, extent of muscle fatigue and the time required for its recovery and slow/fast twitch muscle contraction. Therefore, based on specific variations within these genes in a person’s DNA, the type of exercise (endurance/sprinting) suitable for that person can be determined.
