When considering the scientific lack concerning the execution and acute effects and mechanism of foam rolling (FR), this study has evaluated the biomechanical loads by the force-time characteristics during two popular FR exercises. Additionally, the acute effects of FR on jump height and muscular stiffness were simultaneously assessed. Within a randomized cross-over design, 20 males (26.6 ± 2.7 years; 181.6 ± 6.8 cm; 80.4 ± 9.1 kg) were tested on different days pre, post, and 15 and 30 min after three interventions. The interventions consisted of a FR procedure for the calf and anterior thigh of both legs, 10 min ergometer cycling, and resting as a control. Stiffness was measured via mechanomyography at the thigh, calf, and ankle. The vertical ground reaction forces were measured under the roller device during FR as well as to estimate jump height. Within the FR exercises, the forces decreased from the proximal to distal position, and were in mean 34 and 32% of body weight for the calves and thighs, respectively. Importantly, with 51 to 55%, the maxima of the individual mean forces were considerably higher. Jump height did not change after FR, but increased after cycling. Moreover, stiffness of the thigh decreased after FR and increased after cycling.
考虑到关于泡沫轴放松（FR）的实施、急性效应和机制方面的科学研究不足，本研究通过两种常见的FR练习过程中的力-时间特性评估了生物力学负荷。此外，还同时评估了FR对跳跃高度和肌肉僵硬度的急性效应。在随机交叉设计中，对20名男性（26.6±2.7岁；181.6±6.8厘米；80.4±9.1千克）在三种干预前、干预后以及干预后15分钟和30分钟的不同日期进行了测试。干预措施包括对双腿小腿和大腿前部进行FR操作、10分钟的测力计骑行以及作为对照的休息。通过肌动图测量大腿、小腿和脚踝处的僵硬度。在FR过程中，在滚筒装置下方测量垂直地面反作用力以及估计跳跃高度。在FR练习中，力从近端到远端位置逐渐减小，小腿和大腿的平均力分别为体重的34%和32%。重要的是，个体平均力的最大值分别高出51%至55%。FR后跳跃高度没有变化，但骑行后增加。此外，FR后大腿僵硬度降低，骑行后增加。
