Summary

This study investigates the effects of cooling on the recovery and performance characteristic in young healthy subjects. The study is divided in two projects: Project A: investigates the effects of 20 min. post-exercise cooling on vertical jump performance and delayed onset muscle soreness and rated perceived exertion. Project B: investigates the effects of 20 min. pre-exercise cooling on maximal voluntary contraction of the right M. quadriceps femoris and delayed onset muscle soreness and rated perceived exertion.
