Summary

This study looks at how the body's markers of muscle damage change after a tough leg workout, and whether doing the same workout again causes less damage (the 'repeated bout effect'). 48 healthy, active men will do eccentric knee exercises on a machine. Researchers will measure pain, strength, movement, oxygen levels, and blood markers before and two days after exercise.
