Abstract
Background: The sit and reach test (SRT) is an evaluation of muscle extensibility. Most studies adopting the SRT do not provide information about the warm-up. Whole body vibration (WBV) is a training that has positive outcomes also on flexibility performance. It was decided to evaluate how warm-up, also with WBV, influences flexibility and to propose a standard operating procedure that adopts this instrument.
Methods: Ninety participants performed the SRT three times: half performed it with WBV to maximize the performance; half underwent a passive rest between the SRT. Data were analyzed with the Friedman Test and the Pairwise Comparisons Durbin-Conover.
Results: Differences between SRT repetitions were reduced after two trials. SRT1 vs. SRT2 presented a difference of 1.1 cm (P=0.063), and SRT2 and SRT3 had a difference of 1 cm (P=0.453). The SRT results with WBV provided a valuable difference between the first and the second trial of 3.1 cm (P<0.001) while between the second and the third was 0.3 cm (P=0.609). No statistical differences were between SRT3 with and without WBV (P=0.384).
Conclusions: There was an acute positive effect of WBV on flexibility. The findings also suggest that before the SRT, participants had to perform a standardized warm-up.
背景:坐伸测试(SRT)是一种评估肌肉延伸性的方法。大多数采用SRT的研究不提供热身的信息。全身振动(WBV)是一种对柔韧性表现也有积极效果的训练。会议决定评估热身(也包括WBV)对灵活性的影响,并提出采用这一工具的标准操作程序。方法:90名被试进行了三次SRT测试,其中一半的被试使用WBV进行SRT测试,以最大限度地提高测试效果;一半的人在SRT之间进行被动休息。采用Friedman检验和Durbin-Conover两两比较对数据进行分析。结果:两次试验后,SRT重复数之间的差异减小。SRT1与SRT2的差异为1.1 cm (P=0.063), SRT2与SRT3的差异为1 cm (P=0.453)。在第一次和第二次试验中,WBV的SRT结果提供了3.1 cm的有价值的差异(pp结论:WBV对柔韧性有急性的积极影响。研究结果还表明,在SRT之前,参与者必须进行标准化的热身。
