概括
更高的有氧能力与多发性硬化症 (pwMS) 患者的疲劳降低有关,可能是通过其对后背乳头核的影响. 这种关系可能不同于认知和身体疲劳.
科学领域:
- 神经科学是一个神经科学.
- 康复医学 康复医学 康复医学
- 医疗成像医学成像
背景情况:
- 疲劳显著影响多发性硬化症 (pwMS) 患者,影响身体和认知功能.
- 降低有氧能力和thalamic体积与pwMS疲劳的病理生理学有关.
研究的目的:
- 为了确定pwMS中乳头核体积,有氧能力和疲劳水平之间的关联.
- 调查体完整性是否调解了pwMS中的有氧能力和疲劳之间的关系.
主要方法:
- 83个 pwMS 完成了疲劳评估 (修改疲劳影响量表 (MFIS)) 和氧气吸收峰值 (VO2峰值) 测试.
- 脑部MRI扫描被用来测量pwMS和63名健康对照 (HC) 中的整个丘脑和丘脑核体积.
主要成果:
- 与HC相比,PwMS的MFIS得分更高,VO2峰值和thalamic体积更低.
- 增加的VO2峰值与降低的MFIS和物理MFIS (pMFIS) 评分相关,并在pWMS中增加了后背侧核 (Dor) 体积.
- 减少多体群体体积与增加的MFIS,pMFIS和认知MFIS (cMFIS) 评分有关.
- 多尔体群体体积部分介导了VO2峰对MFIS (21%) 和cMFIS (32%) 的影响.
结论:
- 升高的VO2峰值与pwMS中疲劳的减少有关,可能是通过其对Dor体群的影响.
- 在pwMS中,有氧能力对疲劳的影响可能在认知和身体疲劳类型之间有所不同.

Muscle Recovery and Fatigue
2.1K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Exercise and Cardiac Output

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
