Question

请帮我翻译一段英文

A display of "strength" (e.g. lifting a weight) is a result of three factors that overlap: physiological strength (muscle size, cross sectional area, available crossbridging, responses to training), neurological strength (how strong or weak is the signal that tells the muscle to contract), and mechanical strength (muscle's force angle on the lever, moment arm length, joint capabilities). Contrary to popular belief, the number of muscle fibres cannot be increased through exercise; instead the muscle cells simply get bigger. Muscle fibres have a limited capacity for growth through hypertrophy and some believe they split through hyperplasia if subject to increased demand

Answer 1

显示“力量”（例如举起的重量）是由于三个因素：生理强度重叠（肌肉大小，横截面面积，可交联，反应强度训练），神经系统（多强或弱的信号，告诉肌肉收缩），和机械强度（肌肉的力角的杠杆，力臂长度，关节功能）。与流行的信念相反，一些肌肉纤维不能通过增加运动；相反，肌肉细胞只得到更大。肌肉纤维有能力有限增长肥厚和一些相信他们分裂增生如果通过主体的需求增加
