Introduction A warm-up is often performed to prevent injury and prepare for optimal performance. Nonetheless, research on its impact on performance, particularly in para-sports, remains limited. We hypothesized that the use of an assistive device during warm-up would enable wheelchair basketball players to perform full-body movements efficiently and effectively, contributing to enhanced wheelchair mobility. Therefore, this feasibility study aimed to assess the safety of warm-up exercise with an assistive device and the changes in wheelchair mobility performance before and after warm-up in able-bodied participants. Methods Thirteen able-bodied participants (nine males and four females; mean age: 34.3 ± 6.11 years) were analyzed. Warm-up consisted of a five-minute stand-up exercise using the lumbar-type Hybrid Assistive Limb. Before and after warm-up, a 3-3-6 m sprint was performed as a wheelchair mobility performance test. The 3-3-6 m sprint is a test in which the athlete repeatedly accelerates, decelerates, and stops while driving at maximum effort for a total of 12 m (0-3 m, 3-6 m, and 6-12 m). The time required for the 3-3-6 m sprint and maximum instantaneous speed, acceleration time, deceleration time, hip joint angle, and average muscle activity of the lower limb and trunk muscles during the acceleration/deceleration phase of each section were compared before and after warm-up exercise. Results Warm-up with an assistive device was safe in healthy participants. The time required for the 3-3-6 m sprint was significantly reduced after the warm-up compared to that before the warm-up (p=0.005). Although not significant, there was a trend toward shorter deceleration times after the warm-up for participants herein. Conclusions In able-bodied participants, warm-up with an assistive device is safe; it may improve wheelchair mobility performance. Further research is required to determine its impact on para-athletes with disabilities.
引言 热身运动通常用于预防受伤并为最佳表现做准备。然而，关于其对运动表现的影响，尤其是在残疾人体育运动中的影响，研究仍然有限。我们假设在热身过程中使用辅助设备能够使轮椅篮球运动员高效且有效地进行全身运动，从而提高轮椅的移动性。因此，本可行性研究旨在评估使用辅助设备进行热身运动的安全性，以及健全参与者在热身前后轮椅移动性能的变化。
方法 对13名健全参与者（9名男性和4名女性；平均年龄：34.3±6.11岁）进行了分析。热身包括使用腰部型混合辅助肢体进行5分钟的站立运动。在热身前后，进行了3-3-6米短跑作为轮椅移动性能测试。3-3-6米短跑是一项测试，运动员在全力驱动轮椅的过程中，总共12米（0-3米、3-6米和6-12米）反复加速、减速和停止。比较了热身运动前后3-3-6米短跑所需的时间、最大瞬时速度、加速时间、减速时间、髋关节角度以及每个路段加速/减速阶段下肢和躯干肌肉的平均肌肉活动。
结果 在健康参与者中，使用辅助设备进行热身是安全的。与热身前相比，热身之后3-3-6米短跑所需的时间显著减少（p=0.005）。虽然不显著，但本文中的参与者在热身之后减速时间有缩短的趋势。
结论 在健全参与者中，使用辅助设备进行热身是安全的；它可能会改善轮椅移动性能。需要进一步的研究来确定其对残疾运动员的影响。
