Genetic Variation and the Efficacy of Aerobic Exercise

Effects of Genetic Variation on the Efficacy of Aerobic Exercise

This study investigates whether, after six weeks of exercise, a genetic variant (Val66Met) in the gene that makes a molecule (BDNF) important for brain health and function, influences the beneficial effects of a further session of exercise in sedentary, healthy males. The aim of this research is to determine whether not having this genetic variant (Val66Met) provides an advantage for achieving greater exercise-induced benefits. After six consecutive weeks of exercise (high-intensity interval training (HIIT), three times per week), the effects of a further session of exercise on brain activity are studied in healthy, sedentary males with and without the BDNF genetic variant. Further, whether the BDNF genetic variant impacts the effects of six weeks of aerobic exercise on blood BDNF levels, memory and cardiorespiratory fitness is examined. This data will help to understand whether genetic factors moderate the beneficial effects of exercise. Understanding what factors influence the effectiveness of exercise training programs is essential to individualize exercise programs and maximize their positive effects on the brain and during rehabilitation following brain injuries.

Behavioral - High-Intensity Interval Training (HIIT)

Participants perform high-intensity interval training (HIIT) on a cycle ergometer. The HIIT protocol consists of a 3-minute warm-up at 50W, ten 60-second high-intensity cycling intervals interspersed with 90 seconds of active recovery at 30% of their peak power output and a 2-minute cool-down at 50W for a total of 17.5 minutes.
