概括

带电极骨肌刺激 (B-SES) 提供了一个替代性的运动疗法. 在B-SES期间的峰值氧气吸收接近传统运动测试中的无氧值,这表明其潜在的实用性.

科学领域:

运动生理学运动生理学
康复医学康复医学康复医学
生物医学工程生物医学工程

背景情况:

皮带电极骨肌肉刺激 (B-SES) 正在被探索为具有有限自愿运动能力的个体的替代性运动疗法.
通过B-SES实现的氧气吸收 (VO2) 与使用自愿运动的传统心肺运动测试 (CPX) 的可比性仍然不清楚.

研究的目的:

评估和比较氧气吸收 (VO2) 和乳酸 (LA) 生产在增量B-SES与人体表CPX.
为了确定B-SES和人体表CPX参数之间的关系,包括VO2和LA响应.

主要方法:

一项跨界设计研究,涉及10名健康的日本年轻参与者.
参与者接受了增量B-SES CPX和人体表 CPX,两者都使用了20W的道协议.
进行了血清乳酸度 (LA) 和血诺上腺素的连续测量,B-SES耐受性根据LA (ΔLA) 的变化进行了调整.

主要成果:

在B-SES期间的峰值VO2 (14.1±3.3毫升/公斤/分钟) 显著低于在人体表CPX期间的峰值VO2 (30.2±6.2毫升/公斤/分钟,P<0.001).
在B-SES中,VO2峰值与人体表 CPX (15.1±2.6毫升/公斤/分钟) 中观察到的无氧值 (AT) VO2相当.
在B-SES后,LA和血诺上腺素水平增加. 虽然B-SES峰值VO2与人体表CPX没有直接相关,但B-SES峰值VO2与ΔLA的比率显示出与人体表CPX峰值VO2在耐受性调整后的显著相关性 (r=0.688,p=0.028).

结论:

被动渐进的B-SES可以在没有不良事件的情况下达到接近人体表CPX的AT的VO2峰值水平.
调整为 ΔLA 的 B-SES 峰值 VO2 的比率可以作为 ergometer CPX 期间峰值 VO2 的预测措施.

Muscle Recovery and Fatigue

Muscle Recovery and Fatigue

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...

Muscle Stimulation Frequency

Muscle Stimulation Frequency

The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Energy Supply for Muscle Contraction

Energy Supply for Muscle Contraction

Skeletal muscle fibers have the unique ability to switch between rest and contraction states, using different sources of ATP for energy. The contraction cycle and Ca2+ transport back into the sarcoplasmic reticulum for relaxation require significant ATP. However, the ATP reserves in muscle fibers are limited and can only sustain contractions for a few seconds. Additional ATP production becomes necessary for prolonged contractions. As a result, muscle fibers generate ATP through various sources,...
