Assessment of repeated vertical jump for anaerobic exercise performance

Abstract

Background: Lower body power and strength are important in many sports such as volleyball and basketball. One way to assess explosive lower body power and strength is to measure maximal height during vertical jump, which is decreased with muscular fatigue. In the current investigation, we developed and tested a new protocol for anaerobic vertical jump performance with a frequency of 12 jumps/min. To do this, we assessed three rounds of 30 consecutive vertical jump performance with 5-minute resting period. Methods: Twelve young, healthy, and recreationally active males (25.4 1.4 yrs., 79.2 3.2 kg, 178.2 1.7 cm) participated in the current study. Subject performed a total of 3 sets of 30 consecutive maximal vertical jumps with 5 min recovery period following each set. After the first (ROUND 1) and second set (ROUND 2) of vertical jump exercise, subjects rested in the chair for 5 min. Following the last set of vertical jump exercise (ROUND 3), subjects rested for 30 min. Results: In all rounds, vertical jump height steadily decreased during 30 consecutive jumps (p
