This study aimed to compare and examine the local and non-local effects of a foam rolling (FR) and static stretching (SS) intervention applied to the plantar flexor (PF).
Fourteen female participants were investigated. Each participant underwent three conditions in a random order at least 48h apart and at the same time of the day: Control (CC), SS, and FR. Each condition was performed unilaterally in the dominant PF for 4 sets (apart from CC). SS was performed for 30 s. The FR included 30 rolls (15 in each direction) over a period of 30 s. A rest of 30 s was provided between each set for all conditions. Outcome variables were ankle dorsiflexion range of movement (ROM), tissue hardness, localized bioimpedance analysis at 50 kHz (L-BIA), and pain pressure thresholds (PPT). Tissue hardness, L-BIA, and PPT were measured in the lower leg and thigh. Measures were assessed pre (T0), immediately post (T1), and 10-min after (T2) the intervention.
No differences were found for time for the CC or between the T0 of each condition. Concerning the lower leg, ROM improved for SS and FR from T0 to T1 while returning to baseline in T2. A significant increase in PPT was observed only for SS in T1. L-BIA showed a significant increase for both phase angle and impedance only for FR in T1. Tissue hardness did not change for any group at any time-point. Concerning the thigh, no measure at any time point showed significant differences.
Both, FR and SS were able to acutely improve ankle ROM. The observed changes were probably caused by a change in viscoelastic properties and local pain perception, without any variation in tissue morphology. FR was the only intervention to improve the intracellular-to-extracellular ratio and decrease fluids. Non-local effects were not observed.
本研究旨在比较和检验对跖屈肌（PF）进行泡沫轴放松（FR）和静态拉伸（SS）干预的局部和非局部效应。
对14名女性参与者进行了调查。每位参与者以随机顺序在至少间隔48小时且每天同一时间接受三种情况：对照（CC）、SS和FR。每种情况均在优势PF上单侧进行4组（CC除外）。SS进行30秒。FR包括在30秒内进行30次滚动（每个方向15次）。所有情况在每组之间均提供30秒的休息时间。结果变量包括踝关节背屈活动范围（ROM）、组织硬度、50kHz时的局部生物电阻抗分析（L-BIA）和疼痛压力阈值（PPT）。在小腿和大腿测量组织硬度、L-BIA和PPT。在干预前（T0）、干预后立即（T1）和干预后10分钟（T2）进行测量。
CC组的时间以及每种情况的T0之间均未发现差异。关于小腿，ROM从T0到T1在SS和FR时均有所改善，而在T2时恢复到基线。仅在T1时观察到SS的PPT显著增加。L-BIA仅在T1时显示FR的相角和阻抗均显著增加。任何组在任何时间点的组织硬度均未改变。关于大腿，在任何时间点的任何测量均未显示出显著差异。
FR和SS均能急性改善踝关节ROM。观察到的变化可能是由粘弹性特性和局部疼痛感知的变化引起的，而组织形态没有任何变化。FR是唯一能改善细胞内与细胞外比例并减少液体的干预措施。未观察到非局部效应。
