A dynamic warm-up (DWU) comprising exercise involving rhythmic muscle actions results in an acute increase in range of motion; however, recent findings suggest that a passive one using self-massage techniques might elicit a similar effect. This study's purpose was to compare the acute effect of leg cycling DWU on sit-and-reach score to the effect of a preparatory regimen of foam rolling (FR) or percussive massage (PM).
Single-blind, randomized, repeated-measures crossover study.
Thirty-two asymptomatic, physically-active participants (male; n = 17) aged 20.9 ± 1.5 years performed sit-and-reach tests before, immediately following and 10-, 20- and 30-minutes following eight minutes of each of the "warm-ups." Analyses of variance at each time point across conditions and for the percent change elicited by each intervention were conducted to determine significant differences (p < 0.05).
Repeated-measures ANOVA revealed a significant difference between mean percent difference of sit-and-reach score for FR (8.8 ± 0.5%) compared to DWU and PM (p = 0.046 and 0.048, respectively) while DWU (6.3 ± 0.8%) and PM (6.8 ± 0.5%) did not differ (p = 0.717). There were no differences between scores across interventions at any of the four time points.
A bout of FR or PM resulted in an acute increase in a sit-and-reach score during a test performed immediately post and at 10-, 20- and 30-minutes post that was similar in magnitude to that which was present following leg cycling. These passive "warm-ups" are appropriate alternate strategies that can be employed to improve performance on a sit-and-reach test.
包含有节奏肌肉运动的动态热身（DWU）会导致运动范围的急性增加；然而，最近的研究结果表明，使用自我按摩技术的被动热身可能会产生类似的效果。本研究的目的是比较腿部循环 DWU 对坐立前伸测试得分的急性影响与准备阶段的泡沫轴滚动（FR）或冲击按摩（PM）的影响。
单盲、随机、重复测量交叉研究。
32 名无症状、活跃的参与者（男性；n = 17）年龄为 20.9 ± 1.5 岁，在进行八分钟的“热身”后，分别在立即、10 分钟、20 分钟和 30 分钟进行坐立前伸测试。在每个时间点，通过方差分析来比较条件之间和每个干预措施引起的百分比变化，以确定显著差异（p < 0.05）。
重复测量方差分析显示，FR 的坐立前伸得分平均百分比差异（8.8 ± 0.5%）与 DWU 和 PM 之间存在显著差异（p = 0.046 和 0.048），而 DWU（6.3 ± 0.8%）和 PM（6.8 ± 0.5%）之间没有差异（p = 0.717）。在四个时间点的任何一个干预措施下，得分之间均无差异。
在立即和 10 分钟、20 分钟和 30 分钟的测试中，FR 或 PM 的单次治疗都会导致坐立前伸测试得分的急性增加，其幅度与腿部循环后的得分相似。这些被动的“热身”是可以提高坐立前伸测试表现的适当替代策略。
