Abstract：
Among athletes, foam rolling is popular technique of myofascial release aimed to support recovery processes and counteract delayed onset muscle soreness. However, there is no consensus on the optimal parameters of the roller texture used in the procedure. The study aimed to determine whether using rollers with different textures and hardness (smooth/soft, grooved/mid, serrated/hard) in myofascial release affects post-exertional restitution rate and the level of perceived DOMS (Delayed Onset Muscle Soreness) after intense anaerobic exercise. The study involved 60 healthy and physically active men randomly divided into three experimental groups and one control group (passive rest)-each consisting of 15 individuals: STH-rolling with a smooth roller; G-rolling with a grooved roller; TP-rolling with a serrated roller; Pass-passive rest group. After performing a exercise test (one-minute high-intensity squat), blood lactate (LA), creatine kinase (CK) and pain perception (VAS Scale) were monitored. The analysis of the average LA concentration in the blood 30 min post-exercise showed a statistical difference for all rolling groups compared to the passive rest group: STH (p < 0.001), G (p < 0.001), TP (p = 0.035). No statistically significant differences were found between the CK measurement results in individual assessments. Statistically significant differences in VAS values were observed between G (p = 0.013) and TP (p = 0.006) groups and the Pass group at 48 h, as well as between STH (p = 0.003); G (p = 0.001); TP (p < 0.001) groups and the Pass group at 72 h. Based on statistical data, a strong influence (η2 = 0.578) of time on the quadriceps VAS variable was noted. The research results confirm the effectiveness of rolling in supporting immediate and prolonged recovery. The conducted studies indicate a significantly better pace of post-exertional recovery after a rolling procedure lasting at least 120 s. The texture and hardness of the tool used did not matter with such a duration of the treatment.
摘要：
在运动员中,泡沫滚动是一种流行的肌筋膜释放技术，旨在支持恢复过程并抵消延迟发作的肌肉酸痛。然而,在程序中使用的辊纹理的最佳参数没有共识。该研究旨在确定是否使用具有不同质地和硬度(光滑/柔软，开槽/中间,锯齿状/坚硬）的肌筋膜释放会影响运动后的恢复率和强烈的无氧运动后感觉到的DOMS（延迟发作的肌肉酸痛）水平。该研究涉及60名健康且身体活跃的男性，随机分为三个实验组和一个对照组（被动休息），每组由15个人组成：STH-用光滑辊滚动；G-用槽辊滚动；TP-用锯齿状辊滚动；通过被动休息组。在进行运动测试（一分钟高强度深蹲）后，血乳酸（LA），监测肌酸激酶（CK）和疼痛感知（VAS量表）。对运动后30分钟血液中的平均LA浓度的分析显示，与被动休息组相比，所有滚动组均具有统计学差异：STH（p<0.001），G（p<0.001），TP(p=0.035)。在单个评估中，CK测量结果之间没有发现统计学上的显着差异。在48h时，G（p=0.013）和TP（p=0.006）组和Pass组之间的VAS值存在统计学上的显着差异，以及STH（p=0.003）之间;G（p=0.001）;TP（p<0.001）组和72小时的Pass组。根据统计数据，注意到时间对股四头肌VAS变量的强烈影响(η2=0.578)。研究结果证实了滚动在支持即时和长期恢复方面的有效性。所进行的研究表明，在持续至少120s的滚动程序后，运动后恢复的速度明显更好。所使用的工具的质地和硬度与处理的持续时间无关。
