Influence of Maximal Strength on In-Water and Dry-Land Performance in Young Water Polo Players.

abstract：:The purpose of this investigation was to determine if there were different trends in physical fatigue observed in 3 different sets, of 7 trials each, in repeated sprint training, performed in 3 different modes: straight sprinting over 30 m, shuttle sprinting over 15 + 15 m, and sprinting over 30 m with changes of dire...
