肌纖維破壞的說法哪邊來的...
生理學研究來的吧
肌纖維內的肌原纖維的肌球蛋白絲跟肌動蛋白絲；因為強力的收縮力度導致蛋白絲無法復位而在肌節上出現空隙，就可以說是肌纖維的微小撕裂。 要說成肌纖維破壞也是可以啦..當然破壞有分程度，太嚴重就是斷裂嚴重受傷。

我有問過教練，運動當...(恕刪)
這有相當詳細的解說,
最有效果看你到底想要練什麼.
肌纖維被破壞指的是這類型的.
"Myofibrils are essentially bundles of myofilaments (The contractile parts of a muscle, the parts that pull). They are found in each skeletal muscle fiber.
Each muscle cell contains many myofibrils. Myofibril hypertrophy occurs due to an overload stimulus (lifting more than your body is used to) that applies trauma to the individual muscle fibers. Your body treats this as an injury and as such overcompensates during the recovery process by increasing the volume and density of the myofibrils so that the “injury” does not occur again.
This is one of the reasons why you must maintain overload to continue making gains."
