Monitoring changes in power, speed, agility and endurance in elite cricketers during the off-season

The purpose of this study was to monitor changes in power, speed, agility and endurance in elite cricketers during the 20-week off-season period. Fourteen elite male cricketers (age 26.2 ± 5.3years; height 180.8 ± 8.5cm; mass 83.5 ± 6.7kg) conducted a physical testing battery in week 1 and week 18 of the off-season period. The testing included a yoyo intermittent recovery test (yoyo IRT), bilateral and unilateral countermovement jumps (CMJ), squat jump (SJ), broad jump (BJ), drop jump (to calculate reactive strength index – [RSI]), pro agility and 5, 10, 20m sprint tests. Results showed significant improvements (p < 0.05) in all fitness tests except for the pro-agility test (p = 0.076), with effect sizes ranging from 0.26-2.8 across the test battery. The results of this study show the off-season in cricket allows adequate time for significant improvements of physical qualities needed for the demanding in-season schedule of the sport and provide normative values for an elite cricket population
