Short report: Recovery of jump performance after a simulated cricket batting innings

The time-course of physical recovery was determined after a 2-h 20-min, simulated cricket batting innings. Several vertical jump measures were assessed before (baseline), immediately after, 24 h after and 48 h after simulated batting. Six, male, academy cricketers (20 ± 2 years) completed a previously developed simulated batting innings (BATEX) at an outdoor net facility. At each assessment point, participants completed countermovement-jumps, squat-jumps and 5-repeated reactive-jumps on a contact mat. Compared with baseline, countermovement flight time was similar immediately after, but decreased 24 h after batting (-3.0 ± 1.8%, p < 0.05, effect size ES] ± 90% confidence interval CI]: -1.38 ± 0.52). At 48 h post, countermovement-jump flight time was similar to baseline. A similar pattern occurred in the squat-jump and the decrease in squat-jump flight time 24 h after simulated batting approached significance (p = 0.053, ES ± CI -0.80 ± 0.51). The 5-repeated reactive-jump measures (flight time, contact time and reactive-strength-index) did not decrease after simulated batting (p > 0.05), but there were moderate effect sizes calculated (0.64-0.96). These findings support the continued use of countermovement flight time to assess recovery in cricket, since full recovery of jump performance occurred 48 h after a simulated, prolonged and high intensity-batting century.
