Genes and muscle damage after exercise

This study tests whether a special nutritional supplement helps muscles recover better after exercise. Researchers will compare how well the supplement works in healthy young men who exercise regularly.

This study looks at how your genes affect your endurance performance after drinking caffeine. You will do a cycling test and provide DNA samples. It might help explain why some people respond differently to caffeine during exercise.

This study looks at how aging affects muscle cells, especially mitochondria (the energy powerhouses in your cells). They are comparing people who are very inactive with those who are endurance athletes, in both young and middle-aged groups, to understand how exercise might slow age-related changes.

This study looks at how muscles age in healthy adults. If you join, you'll do some light physical activity as part of the study, and researchers will check your muscle health over time.

This study looks at how different body measurements change after an intensive muscle-building training season, and how those changes relate to improved performance in a middle-distance race. You might be a good match if you’re a 40–60-year-old male athlete in the specific training program and can safely complete all required tests.

This study tests two different types of arm exercises to see how they affect muscle soreness and damage. If you've lifted weights before but aren't currently doing chest presses every week, this may help you understand how your body recovers after different workouts.
