However, this did not improve results in jumping tests, running tests, and other volleyball specific-skills, including speed tests and accuracy during the volleyball serve by glawgii It's because they had only 12 players in the test which is a pathetically small sample making it very unlikely that anything would be significant except by chance. Unfortunately this makes the study a waste of time. Permalink 1
