we investigated the effects of a 10 week training program (i.e., minute oscillatory stretching; MOS) on the mechanical responses and walking capability in people with type 2 diabetes (T2D).
seventeen T2D patients performed maximum voluntary contractions of the plantar flexor muscles during which Achilles tendon stiffness (k) and muscle-tendon stiffness (k) were evaluated at different percentages of the maximum voluntary force (MVC). In addition, each participant was requested to walk at different walking speeds (i.e. 2, 3, 4, 5, and 6 kmh) while their net energy cost of walking (C), cumulative EMG activity per distance travelled (CMAPD) and kinematic parameters (step length, step frequency, the ankle/knee range of motion) were evaluated.
maximum tendon elongation increased after MOS training, and k significantly decreased (between 0 and 20% of MVC). No differences were observed for muscle elongation or k after training. C decreased after training (at the slowest tested speeds) while no changes in CMAPD were observed. Step length and ankle ROM during walking increased after training at the slowest tested speeds, while step frequency decreased; no significant effects were observed for knee ROM.
these results indicate the effectiveness of 10 weeks of MOS training in reducing tendon stiffness and the energy cost during walking in people with T2D. This training protocol requires no specific instrumentation, can be easily performed at home, and has a high adherence (92 ± 9%). It could, thus, be useful to mitigate mechanical tendon deterioration and improve physical behaviour in this population.
我们研究了为期10周的训练计划（即分钟振荡拉伸；MOS）对2型糖尿病（T2D）患者的力学反应和行走能力的影响。
17名T2D患者进行了足底屈肌的最大自主收缩，在此期间，在最大自主力量（MVC）的不同百分比下评估跟腱刚度（k）和肌腱肌肉刚度（k）。此外，要求每位参与者以不同的行走速度（即2、3、4、5和6公里/小时）行走，同时评估他们的行走净能量消耗（C）、每行进距离的累积肌电图活动（CMAPD）和运动学参数（步长、步频、踝关节/膝关节活动范围）。
MOS训练后最大肌腱伸长增加，且k显著降低（在MVC的0%至20%之间）。训练后肌肉伸长或k未观察到差异。训练后C降低（在测试的最慢速度下），而CMAPD未观察到变化。在测试的最慢速度下训练后，行走时的步长和踝关节活动范围增加，而步频降低；膝关节活动范围未观察到显著影响。
这些结果表明，10周的MOS训练在降低T2D患者的肌腱刚度和行走时的能量消耗方面是有效的。该训练方案不需要特定的仪器，可以很容易地在家中进行，并且依从性高（92±9%）。因此，它可能有助于减轻该人群的肌腱机械性退化并改善身体行为。
