Physical activity is known to be an effective way of managing multiple sclerosis (MS)-related symptoms. Furthermore, it has been reported that even a single bout of physical activity can yield improvements in mood in persons with MS. Aquatic exercise can be an effective and enjoyable physical activity in persons with MS. However, there is little research on the immediate effects of aquatic exercise on mood in people with MS. Thus, we assessed the acute effects of a single bout of aquatic exercise on mood.
Eight adults with MS participated in a 45-minute aquatic exercise class as well as 45 minutes of a seated rest control condition. The Profile of Mood States questionnaire was given before and after each condition (rest and aquatic exercise). Repeated-measures analysis of variance and paired-samples tests were used to examine whether aquatic exercise resulted in improvement in mood. Due to the small sample size, effect sizes were considered.
Moderate-to-large effect sizes indicated a condition × time interaction such that mood increased and fatigue decreased after a single bout of aquatic exercise compared with after rest.
This proof-of-concept study suggests that mood symptoms are improved immediately after a short bout of aquatic exercise. Future research is needed to explore whether these effects are reliable and whether they can be sustained with more frequent bouts of aquatic exercise.
众所周知，体育活动是管理多发性硬化症（MS）相关症状的有效方法。此外，据报道，即使单次体育活动也能改善MS患者的情绪。水上运动对MS患者来说可能是一种有效且有趣的体育活动。然而，关于水上运动对MS患者情绪的即时影响的研究很少。因此，我们评估了单次水上运动对情绪的急性影响。
八名成年MS患者参加了一节45分钟的水上运动课程以及45分钟的坐姿休息对照条件。在每种条件（休息和水上运动）前后均进行了情绪状态剖面图问卷调查。采用重复测量方差分析和配对样本检验来检查水上运动是否能改善情绪。由于样本量较小，还考虑了效应量。
中等到较大的效应量表明存在条件×时间交互作用，即与休息后相比，单次水上运动后情绪有所改善，疲劳感有所减轻。
这项概念验证研究表明，短时间的水上运动后情绪症状会立即得到改善。未来需要进行研究，以探索这些效果是否可靠，以及更频繁地进行水上运动是否能维持这些效果。
