Force and power levels after 4-weeks of plyometric training

Fifteen students from the Warsaw University of Physical Education participated in the experiment. After pre-testing, two groups completed 4 weeks of plyometric training with different time of rest periods among series (30 and 120 seconds) Four series of hops above ten hurdles were executed during the one training. Two different heights of hurdles and additional external loads were carried out for individualisation training loads. Our results proved that shorter time of rest period influenced on poor muscle toleration on load and possibilities to recover after a plyometric exercises.
