Abstract

With this study, we aimed to investigate the effects of different warm-up intensities on counter-movement jump (CMJ) performance over time under cold conditions. Eleven male collegiate athletes volunteered. The participants performed high-intensity warm-up (HWU) at 80% VO 2max and moderate-intensity warm-up (MWU) at 60% VO 2max for 15 min on a bicycle ergometer in a laboratory room at 10 °C. CMJ height, vastus lateralis muscle temperature, heart rate, and perceived fatigue were measured before warm-up (Pre), immediately after (Post 0), 10 min after (Post 10), and 20 min after (Post 20). Significant main effects and interactions were found for CMJ height (time, p < 0.001 and η p 2 = 0.859; interaction, p = 0.007 and η p 2 = 0.327). HWU significantly increased CMJ height at Post 0 to Post 20 compared to that at Pre ( p < 0.01), whereas MWU increased CMJ height at Post 0 only compared to that at Pre ( p < 0.001). The results indicate that HWU achieved an increase in CMJ height for 20 min. MWU changed CMJ height instantly, but the change did not last compared to HWU in a cold environment.
