Galis, J and Cooper, DJ. Application of a floss band at differing pressure levels: Effects at the ankle joint. J Strength Cond Res 36(9): 2454-2460, 2022-The study aimed to examine the effects of different levels of pressure on ankle range of motion (ROM), strength, and power performance. A parallel-group design was used, and subjects were divided into 3 groups. After a warm-up and preintervention testing (ankle goniometry using a manual handheld goniometer and isokinetic dynamometry using a HUMAC NORM isokinetic dynamometer), subjects had underwrap (control) or a tissue flossing band, at 150 mm Hg (FLOSS 150 ) or 200 mm Hg (FLOSS 200 ) applied to one of their calves, followed by postintervention testing. Thirty university students participated and completed the testing in a university laboratory: dorsiflexion ROM (DFROM) and plantarflexion ROM (PFROM), peak torque, and power. A repeated-measures analysis of variance with Tukey post hoc showed no statistically significant differences ( p > 0.05) preintervention to postintervention between each group, except for DFROM in FLOSS 150 ( p < 0.05). Medium and small effect sizes preintervention to postintervention were associated with improvements of DFROM (0.61; 95% confidence interval [CI] 0.39-0.83) and dorsiflexion power (0.29; 95% CI -0.13 to 0.72), respectively, in FLOSS 150 , while the effect size of PFROM preintervention to postintervention was -0.35 (95% CI -0.85 to 0.15) in FLOSS 200 . Tissue flossing of the ankle joint may be a useful intervention for increasing dorsiflexion ROM and power, which can be useful for injury prevention, enhancing performance and improving functional ability; however, the potentially harmful effects of the technique should be considered.
加利斯,J 和库珀,DJ。在不同压力水平下应用牙线带:踝关节的影响。J 力量与调理研究 36(9):2454-2460,2022-本研究旨在研究不同压力水平对踝关节活动范围(ROM)、力量和功率性能的影响。采用平行组设计,将受试者分为 3 组。经过热身和干预前测试(使用手动手持量角器测量踝关节角度和使用 HUMAC NORM 等速测力计测量等速动力),受试者在一只小腿上应用包裹(对照)或组织牙线带,压力分别为 150mmHg(FLOSS 150)或 200mmHg(FLOSS 200),然后进行干预后测试。30 名大学生参与并在大学实验室完成了测试:背屈 ROM(DFROM)和跖屈 ROM(PFROM)、峰值扭矩和功率。重复测量方差分析和 Tukey 事后检验显示,除了 FLOSS 150 中的 DFROM(p<0.05)外,每组在干预前到干预后的测量结果之间没有统计学上的显著差异(p>0.05)。干预前到干预后的中等和小效应大小与 DFROM(0.61;95%置信区间[CI]0.39-0.83)和背屈功率(0.29;95%CI-0.13 至 0.72)的改善相关,分别在 FLOSS 150 中,而 FLOSS 200 中干预前到干预后的 PFROM 效应大小为-0.35(95%CI-0.85 至 0.15)。踝关节组织牙线可能是一种增加背屈 ROM 和力量的有用干预措施,这对于预防损伤、提高表现和改善功能能力可能是有用的;然而,应该考虑到该技术的潜在有害影响。
