Foam rolling have gained popularity among elite athletes, but the effect of the speed parameter of foam rolling has not yet been determined. Our objective was to investigate the impact of different application speeds of foam roller on the mechanical properties of the quadriceps femoris muscle. Eighteen male professional basketball athletes (age 23 ± 4 years, body mass index 24.43 ± 1.59 kg/m) participated in this study. We used a crossover design to randomize the order of the treatment speeds (30 beats per minute-FAST, 15 beats per minute-SLOW, and a self-determined speed-SELF) with a one-week washout period between each session. We measured dominant quadriceps femoris muscle tone, elasticity, and stiffness using the Myoton device before and after the interventions. We found that the average rate for SELF was 33±10 beats per minute, making SELF the fastest. All application speeds showed similar results in pre-intervention measurements of the mechanical properties of the tissues ( > 0.05). However, post hoc analysis revealed that a decrease was evident in SLOW compared to SELF in muscle tone in post-intervention measurements ( = 0.037). Also, we noted that comparison of pre- and post-intervention on FAST and SLOW showed a significant reduction in muscle tone ( = 0.002, = 0.008). Slower foam rolling prior to training or competition may lead to a delay in the reaction time due to the reduction in tonus, that can increase the injury risks. Alternatively, the significant reduction in tonus may be useful in regulating the increased tonus after training and competition.
泡沫轴滚动在精英运动员中越来越受欢迎，但泡沫轴滚动速度参数的效果尚未确定。我们的目的是研究不同应用速度的泡沫轴对股四头肌机械性能的影响。18 名男性职业篮球运动员（年龄 23 ± 4 岁，体重指数 24.43 ± 1.59kg/m2）参与了这项研究。我们使用交叉设计随机分配治疗速度的顺序（30 拍/分钟-FAST、15 拍/分钟-SLOW 和自我决定速度-SELF），每次治疗之间有一周的洗脱期。我们使用 Myoton 设备在干预前后测量优势股四头肌的肌张力、弹性和硬度。我们发现，SELF 的平均速度为 33±10 次/分钟，是最快的。所有应用速度在组织机械性能的预干预测量中都显示出相似的结果（>0.05）。然而，事后分析表明，与 SELF 相比，SLOW 在干预后测量中的肌肉张力明显降低（=0.037）。此外，我们还注意到，FAST 和 SLOW 的干预前后比较显示肌肉张力明显降低（=0.002，=0.008）。在训练或比赛前进行较慢的泡沫轴滚动可能会由于张力降低而导致反应时间延迟，从而增加受伤风险。或者，张力的显著降低可能有助于调节训练和比赛后的张力增加。
