Hill, LR. Acute effects of postactivation potentiation on ball velocity in cricket batting. In cricket an increase in ball velocity has been shown to improve the probability of scoring boundaries in cricket and therefore is correlated with achieving higher scores and strike rates. The purpose of this study was to investigate the effect of a postactivation potentiation (PAP) intervention on cricket ball velocity during a front foot drive shot. A Bushnell Radar Gun was used to record the ball velocity of 14 cricketers (age 20 ± 2 years, height 1.85m ± 0.07m, mass 81kg ± 8.3kg) during 2 testing sessions separated by 40 minutes. The mean of 3 front foot drive shots was recorded for baseline, control and PAP following 3 counter movement jumps (CMJ’s). For all participants a decrease in ball velocity of -0.5 mph (effect size, 0.1; p > 0.05) was recorded after the CMJ intervention and an increase in ball velocity of 15.3 mph (effect size, 0.9; p < 0.05) was recorded after the CMJ intervention for responders. Therefore, in certain individuals’, acute enhancements in ball velocity is possible when performing a CMJ before a front foot drive. This may have implications for cricket training programmes and in game preparation as a result of increased ball distance and possible improvements in score.
