本文探讨了肌肉收缩的机制、神经系统的机能状态、肌肉的初长度、肌肉的生理横切面,单个肌纤维收缩的力量,肌肉收缩的数量、体积与力量素质的关系等。并对与力量素质有关的其它因素,年龄、性别、温度、角度等情况进行了研究。总结了各种力量训练的运动负荷,方法和动作幅度。 This article explores the mechanism of muscle contraction, the functional status of the nervous system, the initial length of the muscle, the physiological cross-section of the muscle, the power of contraction of individual muscle fibers, the amount of muscle contraction, and the relationship between volume and strength. And other factors related to strength and quality, age, gender, temperature, angle and so on were studied. Summarized the various types of strength training exercise load, methods and range of motion.
