A Comparative Study on the Performance Profile of Under-17 and Under-19 Handball Players Trained in the Sports School System.

This study evaluates the anatomical profiles, jump, sprint, power outputs, endurance, and peak blood lactate levels ([LA]) of handball players of two age groups-U17 ( = 77) and U19 ( = 46)-and analyses the role of training in their physical abilities. Vertical jump performance was determined by counter movement jump (CMJ) and counter movement jump with free arms (CMJFA) tests. A running-based anaerobic sprint test (RAST) determined the relative power output (watts/kg body weight) and absolute power output (watts) of the players.
