概括

认知运动双任务 (CMDT) 训练,与传统的高强度间歇训练 (HIIT) 不同,有效地防止中枢神经系统疲劳,并减少强度炼期间的精神努力. 这种CMDT特定的培训可以提高训练有素的成年人的认知表现和耐力.

科学领域:

运动生理学运动生理学
神经科学是一个神经科学.
运动科学运动科学运动科学

背景情况:

强烈的认知运动双重任务 (CMDTs) 可以导致中枢神经系统疲劳和认知功能下降,即使在健康的个体.
高强度间歇训练 (HIIT) 是一种常见的训练方法,但它对CMDT诱导的疲劳的影响尚未完全理解.

研究的目的:

调查CMDT特定训练在强烈的CMDT期间预防中心疲劳和认知衰退的有效性.
在训练有素的成年人中,将CMDT训练与传统HIIT进行比较.

主要方法:

40名受过培训的成年人参加了为期4周的培训计划,每周有2次培训.
参与者被分为三个组:单独HIIT (HIIT_CTRL),HIIT与低强度间隔的认知训练 (HIIT_DTL),或HIIT与高强度间隔的认知训练 (HIIT_DTH).
训练包括自我选择的高强度间隔. 训练前和训练后的评估包括一个增量循环认知测试 (ICCT) 来测试任务失败,持续的注意力,神经肌肉功能,前额叶皮层氧化和感知的炼.

主要成果:

所有组都表现出改善的ICCT耐力时间,并在训练后持续提高注意力.
与HIIT_CTRL组相比,CMDT训练组 (HIIT_DTL和HIIT_DTH) 在任务失败时自愿激活 (VA) 的下降明显较小.
此外,CMDT培训也导致了在ICCT后期培训期间感知到的精神努力的更大降低.

结论:

虽然传统的HIIT提高了耐力和注意力,但CMDT特定的训练在减轻中枢疲劳方面提供了卓越的好处.
在要求认知运动任务的过程中,CMDT训练在减少感知到的精神努力方面更有效.
这些发现表明,将认知任务纳入训练方案可以提高受过训练的个体对疲劳的弹性.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Exercise and Cardiac Output

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.
Sustained exercise increases the muscles' oxygen demand, which can be met...

Exercise Stress Test

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
