Tissue flossing (TF) is a novel technique designed to improve muscle and joint function and performance. This study investigated the effects of TF on exercise-induced muscle damage (EIMD) in 24 males randomized into TF (n = 12) or control (CON, n = 12) groups. Participants performed dominant thigh quadriceps isokinetic eccentric exercises to induce EIMD, 10 sets × 12 repetitions. The TF group performed TF interventions (active movement during floss band wrapping, three times a session) immediately after and 24-48 h postexercise. Creatine kinase (CK), knee extensor eccentric strength, pressure pain threshold (PPT), and deep fascia sliding (DFS) of quadriceps were measured at baseline and 24, 48, and 72 h postexercise. CK levels significantly increased over time postexercise, with CON showing a greater increase than TF (all p < 0.05). Knee extensor eccentric strength returned to baseline levels for TF at 48 h (= 0.081) and CON at 72 h (= 0.058), with TF showing greater improvement postexercise (all p < 0.05). Both groups' rectus femoris PPT returned to baseline at 72 h (TF, = 0.303; CON, = 0.272). However, only TF returned to baseline in the vastus medialis PPT and DFS at 72 h and the vastus lateralis DFS at 48 h (all p > 0.05). Furthermore, the PPT and DFS of the vastus medialis and lateralis were significantly greater in TF than in CON over time postexercise (all p < 0.05). Overall, TF is an effective strategy for alleviating EIMD after high-intensity exercise.
组织梳理（TF）是一种旨在改善肌肉和关节功能及表现的新技术。本研究调查了TF对24名男性运动诱导的肌肉损伤（EIMD）的影响，这些男性被随机分为TF组（n = 12）或对照组（CON，n = 12）。参与者进行优势大腿股四头肌等速离心运动以诱导EIMD，共10组，每组12次重复。TF组在运动后立即以及运动后24 - 48小时进行TF干预（在弹力带缠绕过程中进行主动运动，每次训练3次）。在基线以及运动后24、48和72小时测量肌酸激酶（CK）、膝关节伸肌离心力量、压力疼痛阈值（PPT）和股四头肌的深筋膜滑动（DFS）。运动后CK水平随时间显著升高，CON组的升高幅度大于TF组（所有p < 0.05）。TF组在48小时时膝关节伸肌离心力量恢复到基线水平（p = 0.081），CON组在72小时时恢复到基线水平（p = 0.058），TF组在运动后的改善更明显（所有p < 0.05）。两组的股直肌PPT在72小时时均恢复到基线水平（TF组，p = 0.303；CON组，p = 0.272）。然而，只有TF组的股内侧肌PPT和DFS在72小时时恢复到基线水平，股外侧肌DFS在48小时时恢复到基线水平（所有p > 0.05）。此外，运动后随着时间推移，TF组股内侧肌和股外侧肌的PPT和DFS显著高于CON组（所有p < 0.05）。总体而言，TF是减轻高强度运动后EIMD的有效策略。
