Brief Summary:
The purpose of this study is to evaluate the effects of experimental knee pain on the muscle strength gain after 8 weeks of strengthening exercises for the quadriceps. It is hypothesized that experimental knee pain will reduce the muscle strength gain following strengthening exercises in healthy volunteers.
