Self-massage tools such as foam rollers and massage balls are widely used in warm-ups and recovery, but their effects on dynamic strength tasks like squatting remain unclear. To compare the effects of a foam roller (FR), massage ball (MB), and vibrating massage ball (MBV) versus a control condition on squat load velocity profiles and associated electromyographic (EMG) activity in resistance-trained individuals. In this crossover study, fourteen experienced resistance-trained participants performed four experimental conditions: FR, MB, MBV, and control. After an initial session for incremental load testing and protocol familiarization, each participant performed eight back squats before and after each experimental session, while movement velocity, hip vertical displacement (range of motion), and EMG of the vastus lateralis and semimembranosus were recorded. MBV produced a significant increase in quadriceps EMG during the fastest repetition (β = 0.107; p = 0.003). In contrast, all interventions elicited a reduction in the second fastest repetition versus control (FR: β = -0.033, p = 0.005; MB: β = -0.025, p = 0.029; MBV: β = -0.036, p = 0.002). Moreover, both FR and MBV similarly decreased third fastest repetition and mean velocities relative to control (FR: third fastest repetition β = -0.025, p = 0.027; mean β = -0.046, p = 0.046; MBV: third fastest repetition β = -0.032, p = 0.005; mean velocity β = -0.031, p = 0.004). There were no significant changes in the hip vertical displacement. All self-massage conditions modestly impaired squat velocity, with the MB showing the least detrimental effect on performance.
泡沫轴和按摩球等自我按摩工具在热身和恢复过程中被广泛使用，但其对深蹲等动态力量任务的影响仍不明确。为了比较泡沫轴（FR）、按摩球（MB）和振动按摩球（MBV）与对照条件对阻力训练个体深蹲负荷速度曲线及相关肌电图（EMG）活动的影响。在这项交叉研究中，14名有经验的阻力训练参与者进行了四种实验条件：FR、MB、MBV和对照。在进行初始递增负荷测试和熟悉实验方案的环节后，每位参与者在每个实验环节前后各进行8次后深蹲，同时记录运动速度、髋关节垂直位移（运动范围）以及股外侧肌和半膜肌的肌电图。在最快重复动作期间，MBV使股四头肌肌电图显著增加（β = 0.107；p = 0.003）。相比之下，与对照相比，所有干预措施都使第二快重复动作的速度降低（FR：β = -0.033，p = 0.005；MB：β = -0.025，p = 0.029；MBV：β = -0.036，p = 0.002）。此外，与对照相比，FR和MBV均同样降低了第三快重复动作速度和平均速度（FR：第三快重复动作β = -0.025，p = 0.027；平均速度β = -0.046，p = 0.046；MBV：第三快重复动作β = -0.032，p = 0.005；平均速度β = -0.031，p = 0.004）。髋关节垂直位移没有显著变化。所有自我按摩条件均适度降低了深蹲速度，其中MB对运动表现的不利影响最小。
