- 贝叶斯统计方法用于分析标准化平均差异 (SMD) 和日志响应比率 (lnRR).
- 评估肌肉大小的百分比变化,考虑各种影响因素.
主要成果:
- 绝对肌肉大小的增加在男性中略大 (SMD = 0.19).
- 相对肌肉大小的增加在两性之间是可比的 (例如. % lnRR 的变化 = 0.69%).
- 身体上部缩绝对有利于男性;身体下部缩是相似的. 第一种类型的纤维缩有利于男性,而第二种类型类似.
结论:
- 女性具有与男性相似的相对肌肉缩潜力.
- 研究结果表明,高的性别差异受测量 (绝对与相对) 和身体区域的影响.
- 未来的研究应该探索高训练的个体和特定类型的肌肉纤维的性别差异.

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...

Classification of Skeletal Muscle Fibers
55.8K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.
