Influence of pilates exercises on soil stabilization in lumbar muscles in older adults

The practice of regular physical activity is recognized as a strong ally of active aging, healthy, or successful, whose hallmark is the independent and effective performance of activities of daily living. The Pilates Method (MP) has emerged as a good alternative physical activity in older adults with the main objective of strengthening and stretching the muscles simultaneously, raising body awareness. The aim of this study was to analyze the effects of MP on the strength and conductivity of the electrical stimulation of the lumbar paraspinal muscles as well as muscle contraction transversus abdominis (TrA) in older women before and after performing Pilates exercises on the ground. The instruments used were surface electromyography, force transducer and pressure biofeedback unit. Participants were aged 13, who underwent 12 sessions of Pilates exercises on the ground with an average duration of 50 minutes, are reviewed at the end of the intervention protocol. The participants had increased strength and electrical activation of the lumbar paraspinal muscles, as well as increased ability to contract the transversus abdominis muscle. Based on the results obtained we can conclude that there was a significant improvement of strength and electrical conductivity of the stabilizing muscles of the lumbar voluntary and therefore training with MP positively influenced this musculature.

规律进行身体活动被公认为积极老龄化（涵盖健康老龄化与成功老龄化）的重要支撑力量，而积极老龄化的核心表征为个体能够独立且高效地完成各项日常生活活动。普拉提训练法（Pilates Method, MP）现已成为老年群体中极具优势的身体活动备选方案，其核心目标为同时实现肌肉强化与拉伸，并提升身体感知意识。本研究旨在分析针对老年女性群体，在开展地面普拉提训练前后，普拉提训练法对腰椎旁肌群的肌力与电刺激传导特性，以及腹横肌（transversus abdominis, TrA）收缩状态的影响。本研究采用的测评工具包括表面肌电图（surface electromyography）、测力传感器（force transducer）与压力生物反馈单元（pressure biofeedback unit）。受试者共13名，完成了12次地面普拉提训练，单次训练平均时长为50分钟，并于整个干预方案结束后接受了复测。研究结果显示，受试者的腰椎旁肌群肌力与电激活水平均得到提升，腹横肌的收缩能力也有所增强。基于本研究所得结果，可得出结论：腰椎区域自主稳定肌群的肌力与电传导特性均得到显著改善，因此普拉提训练法对该肌群具有积极的正向干预效果。
