概括
肌酸单酸 (CrM) 补充剂最初增加了瘦体质量,特别是在女性身上. 然而,当CrM与12周的抵抗训练相结合时,CrM并没有进一步增强瘦体质量的增加.
科学领域:
- 运动生理学 运动生理学
- 营养科学 营养科学
- 运动医学 运动医学
背景情况:
- 肌酸单 (CrM) 是一种流行的补充剂,用于在抵抗训练期间增加瘦体质量 (LBM).
- CrM可能会影响身体水分,可能会影响LBM测量.
- 这项研究调查了CRM在抵抗训练和没有抵抗训练的情况下对LBM的影响.
研究的目的:
- 评估7天肌酸单 (CrM) 冲洗期对瘦体质量 (LBM) 的影响.
- 为了确定CrM是否会在与12周的抵抗训练计划相结合时增强LBM的效果.
- 检查对CRM补充剂和抵抗训练的性别特异反应.
主要方法:
- 一个随机对照试验,涉及63名参与者 (34名女性,29名男性).
- 参与者接受了13周的每天5g的CrM或安慰剂/没有补充剂.
- 在基线时使用双X射线吸收计测量瘦体质量,在7天的洗后,并在12周的抵抗训练后进行测量.
主要成果:
- 与对照组 (0.51 kg,p=0.03) 相比,CrM组在7天的洗后显示LBM显著增加.
- 这种初始的LBM增长在女性中更为明显.
- 经过12周的力量训练,两组人都获得了相似的LBM增量 (2公斤),CrM和对照组之间没有显著差异.
结论:
- 一个为期7天的肌酸单水合物 (CrM) 冲洗可以急剧增加瘦体质量,特别是在女性身上.
- 当与12周的抵抗训练相结合时,CrM没有提供额外的瘦身质量益处.
- 需要更高的维护剂量CrM可能需要在长时间的抵抗训练计划中增强瘦身量.

Exercise and Muscle Performance
1.3K
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...

Muscle Recovery and Fatigue
1.9K
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...

Energy Supply for Muscle Contraction
2.8K
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,...

Cross-bridge Cycle
116.5K
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
