Understanding the impact of physical activity and its relationship with changes in the biomechanical parameters of the myofascial system at different stages of menopause is important for planning and implementing effective action strategies. The reduction in elasticity and increase in stiffness in upper limb muscles, including in particular tonic muscles, lead to mobility limitations and increased risk of pain. Therefore, the aim of the present study was to evaluate and compare the impact of different types of Nordic walking training on muscle stiffness and elasticity indicators in postmenopausal women.
Thirty women were randomly assigned to two training groups using different kind of poles and completed 8 weeks of training program. Before starting the training programs and after their completion, total fat, lean body mass were measured, along with muscle stiffness and elasticity indicators. Main calculations was based on 2 × 2 analysis of variance ANOVA with repeated measures.
The significant interaction effect was found in differences between the two groups of women with respect to the upper trapezius muscle (p = 0.037). Significant "time" effects were observed for the triceps brachii and brachioradialis muscles (p = 0.032, p = 0.028, respectively) as a result of increased post-intervention muscle stiffness for all participants.
The upper trapezius may be the muscle most strongly engaged during the training, which may lead to sustained passive changes and should have an influence on recommendations on the use of RSA poles in population of postmenopausal women in selected clinical conditions. NW training with RSA poles may be an alternative to traditional NW training for individuals whose physical fitness and health status allows them to engage in such training.
了解体育活动的影响及其在绝经不同阶段与肌筋膜系统生物力学参数变化的关系，对于规划和实施有效的行动策略至关重要。上肢肌肉，尤其是紧张性肌肉的弹性降低和僵硬增加，会导致活动受限和疼痛风险增加。因此，本研究的目的是评估和比较不同类型的越野行走训练对绝经后女性肌肉僵硬和弹性指标的影响。
30名女性被随机分配到使用不同类型手杖的两个训练组，并完成了8周的训练计划。在开始训练计划之前和完成之后，测量了总脂肪、瘦体重以及肌肉僵硬和弹性指标。主要计算基于重复测量的2×2方差分析（ANOVA）。
在两组女性的斜方肌上部差异方面发现了显著的交互作用效应（p = 0.037）。由于所有参与者干预后肌肉僵硬增加，肱三头肌和肱桡肌观察到显著的“时间”效应（分别为p = 0.032，p = 0.028）。
斜方肌上部可能是训练期间参与度最高的肌肉，这可能导致持续的被动变化，并应会影响在特定临床情况下对绝经后女性群体使用RSA手杖的建议。对于身体状况和健康状况允许其进行此类训练的个体，使用RSA手杖的越野行走训练可能是传统越野行走训练的替代方案。
