ABSTRACT
The evaluation of athlete’s physical performance is one of the complex processes that involve sports training. The purpose of this study was to measure the effects of varied rest interval lengths on countermovement jump (CMJ) performance test. The subjects were 12 national athletes from UFMG Sport Training Center, who performed five sessions, two familiarization sessions and three CMJ experimental sessions. The experimental sessions consisted of three sessions with 15 CMJ attempts, each session with a different rest interval duration. The three rest intervals between CMJ attempts were 15, 30, and 60 seconds and were counterbalanced for each subject. No significant difference was founded in the jump height between the 3 pause protocols adopted and between the 15 attempts in the same protocol. Therefore, this study demonstrated a 15 seconds rest interval was sufficient for recovery during the performance of 15 CMJ attempts.
