Muscle strength is essential for autonomy in daily activities and performance in sports activities. Yet, conventional strength training is challenging during recovery from pathological conditions. This study investigates a novel combined intervention employing Focal Muscle Vibration (FMV) and Action Observation (AO) to enhance muscle strength. Twenty-seven healthy volunteers (18 females and 9 males, aged 22 to 42 years) were enrolled for an intervention-control study comparing 2 groups: the intervention group received AO treatment with FMV on the right leg, and the control group underwent only FMV on the right leg. This design allowed the comparison of four conditions: FMV+AO (intervention group, right leg), AO alone (intervention group, left leg), FMV alone (control group, right leg), and no-treatment NT (control group, left leg). The treatment, conducted five times a week (Mon-Fri) for two weeks, involved a 20-minute session of FMV on the right quadriceps, coupled, for the intervention group, with the observation of a gym training video. The assessments of Maximum Voluntary Contraction (MVC), and fatigue coefficient (FC) expressed at knee extension bilaterally were measured at the beginning (T0), after the first week (T1), at the end of treatment (T2), and one-week post-intervention for the follow-up (T3). The FMV+AO group demonstrated a significant improvement in MVC over time, reaching statistical significance at T2 and maintaining the gain at T3. In contrast, all the other conditions demonstrated milder MVC increases without statistical significance. FC did not differ significantly in any condition. The combination of FMV and AO optimized muscle strengthening, offering insights for targeted treatments in various settings.
肌肉力量对于日常活动的自主性和体育活动的表现至关重要。然而，在从病理状况中恢复期间，传统的力量训练具有挑战性。本研究调查了一种采用局部肌肉振动（FMV）和动作观察（AO）来增强肌肉力量的新型联合干预措施。27名健康志愿者（18名女性和9名男性，年龄在22至42岁之间）参与了一项干预对照研究，该研究比较了两组：干预组在右腿接受AO治疗并结合FMV，对照组仅在右腿接受FMV。这种设计允许比较四种情况：FMV+AO（干预组，右腿）、单独AO（干预组，左腿）、单独FMV（对照组，右腿）和无治疗NT（对照组，左腿）。治疗每周进行五次（周一至周五），持续两周，包括在右股四头肌上进行20分钟的FMV训练，对于干预组，还需观看一段健身房训练视频。在开始时（T0）、第一周后（T1）、治疗结束时（T2）以及干预后一周进行随访（T3）时，测量双侧膝关节伸展时的最大自主收缩（MVC）和疲劳系数（FC）。FMV+AO组随着时间的推移MVC有显著改善，在T2时达到统计学显著性，并在T3时保持增益。相比之下，所有其他情况的MVC增加较轻微，无统计学显著性。FC在任何情况下均无显著差异。FMV和AO的组合优化了肌肉强化，为各种情况下的靶向治疗提供了见解。
