概括

北欧腿筋运动 (NHE) 训练通过连续添加瘤来增加腿筋肌肉束的长度和强度. 这些适应在解除训练后部分逆转,突出显示了持续异常训练对肌肉健康的重要性.

科学领域:

肌肉生理学肌肉生理学
运动科学运动科学
生物力学生物力学

背景情况:

奇特的训练,就像北欧腿筋运动 (NHE),用于防止腿筋应变.
以前的研究表明肌肉囊延长和瘤添加,但在人类的直接测量是有限的.
这项研究研究了多尺度腿筋肌肉适应NHE训练和随后的脱训的情况.

研究的目的:

为了测量筋肌肉在囊和肉层面的适应性,以响应NHE训练.
评估肌肉体积和异常强度的变化.
为了评估这些适应在训练期间的可逆性.

主要方法:

12名参与者接受了9周的监督NHE培训,随后进行了3周的脱训.
两腿长头肌 (BFlh) 肌肉囊长度,瘤长度和序列瘤数量被测量.
肌肉体积和古怪的膝盖屈曲强度在基线,训练后和训练后被评估.

主要成果:

NHE培训显著增加了BFlh囊的长度 (最多可达33%) 和连续瘤的数量 (最多可达49%).
训练后肌肉体积增加了8%,异常强度增加了40%.
脱导致囊长度和序列瘤数量的减少.

结论:

九周的NHE训练诱导了BFlh肌肉长度,体积和力量产生的显著,区域特定的增加.
直接测量证实,增加的囊长度是由于连续添加了瘤.
这些发现阐明了人类骨肌肉中异常运动适应的机制.

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...

Isotonic and Isometric Muscle Contractions

Isotonic and Isometric Muscle Contractions

Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.
Isotonic contractions
Isotonic contractions occur when a muscle changes length while...
