随着年龄的增长，跌倒风险的增加增加了对改善平衡和活动能力的方法的需求。该研究的主要目的是确定穿着经过 Aqua Titan 处理的长袜是否可以改善老年人群的平衡和行走能力；其次是阐明机制。在一项随机、双盲交叉试验中，16 名健康老年人（年龄，67.9 ± 4.2 岁；BMI，24.8 ± 3.1 kg/m2）进行了两项为期 4 天的试验，包括基线测量和第一天的疲劳运动，以及运动后 14、38 和 62 小时的恢复测量，穿着 Aqua Titan 和对照长袜。在基线和恢复期间测量平衡、步行表现、小腿三头肌牵张反射、踝关节活动范围和腓肠肌微血管灌注、血流量和耗氧量。 Aqua Titan 对微血管参数没有影响，但在 38 小时（2.4°；95% CI ± 1.8°）和 62 小时（2.7°；±1.7°）时增加了踝关节的总运动范围，这是由于背屈和跖屈的增加所致。与对照长袜相比，38 小时时，内侧-外侧压力运动中心的持久性降低（q = 0, -0.0635 ± 0.0455）。 Aqua Titan 服装具有改善老年人在进行疲劳运动后几天的平衡和活动能力的潜力。所提出的与增强感觉反馈相关的机制需要进一步探索。
The increased risk of falls associated with advancing age has increased demand for methods to improve balance and mobility. The primary purpose of the study was to determine whether wearing Aqua Titan-treated stockings could improve balance and walking performance in an older population; secondary was to elucidate the mechanisms. In a randomized, double-blind crossover, 16 healthy older adults (age, 67.9 ± 4.2 years; BMI, 24.8 ± 3.1 kg/m2) performed two 4-day trials composed of baseline measures and fatiguing exercise on Day 1, with recovery measures at 14, 38 and 62 h post-exercise, wearing Aqua Titan and control stockings. Balance, walking performance, triceps surae stretch reflex, ankle range of motion and gastrocnemius muscle microvascular perfusion, blood flow and oxygen consumption were measured at baseline and during recovery. Aqua Titan had no effect on the microvascular parameters, but increased total ankle range of motion at 38 h (2.4°; 95% CI ± 1.8°) and 62 h (2.7°; ±1.7°), contributed to by increases in dorsiflexion and plantar flexion. There was decreasing persistence in the medial-lateral center of pressure movement at 38 h (q = 0, −0.0635 ± 0.0455), compared to control stockings. Aqua Titan garments hold potential for improving balance and mobility in older adults in the days following a bout of fatiguing exercise. The proposed mechanisms associated with enhanced sensory feedback require further exploration.
