Evidence supports the role of palmar cooling to improve exercise performance, especially with endurance and resistance activities. The aim of this randomized placebo-controlled trial was to explore the effects of palmar cooling on repeated sprinting performance and recovery. Fifteen graduate students were randomly assigned to either a palmar cooling intervention or placebo group (males: n = 8, females: n = 7; Avg. age: 24.06 yrs.) After a ten-minute warm-up, participants completed ten sixty-meter sprints that included two 180-degree changes of direction. Three bouts of two-minute intervention or placebo occurred during the study. Data for sprint times, heart rate, and RPE were collected throughout testing. A muscle soreness rating was collected via survey 48 h post intervention. Statistically and practically significant differences were found between groups for average sprint times, heart rate, and delayed onset muscle soreness. The intervention group utilizing palmar cooling demonstrated less degradation in sprint times, lower heart rate upon completion, and a lower soreness rate 48 h after testing. More research is needed with a larger sample size to determine if practical and statistically significant differences will be maintained and would allow for a more robust multivariant analysis, resulting in the findings being more generalizable to a larger population.
有证据支持手掌冷却对提高运动表现的作用，尤其是在耐力和阻力活动中。这项随机安慰剂对照试验的目的是探讨手掌冷却对重复冲刺表现和恢复的影响。15名研究生被随机分配到手掌冷却干预组或安慰剂组（男性：n = 8，女性：n = 7；平均年龄：24.06岁）。在进行10分钟的热身运动后，参与者完成了10次60米冲刺，其中包括两次180度的方向改变。在研究过程中进行了3次两分钟的干预或安慰剂处理。在整个测试过程中收集了冲刺时间、心率和主观用力程度（RPE）的数据。在干预后48小时通过调查收集肌肉酸痛评分。在平均冲刺时间、心率和延迟性肌肉酸痛方面，两组之间在统计学和实际意义上均存在显著差异。使用手掌冷却的干预组在冲刺时间上的下降较少，完成时心率较低，并且在测试后48小时的酸痛率较低。需要进行更大样本量的更多研究，以确定实际和统计学上的显著差异是否会持续存在，并允许进行更强大的多变量分析，从而使研究结果更能推广到更大的人群。
