[Mechanism study of muscle injury from high tension (I)--The biomechanical effect of training on muscle injury from downhill running in rats].
In this experiment, we tested the biomechanical characteristics of rat's fast and slow skeletal injury from downhill running at different times. The result indicates that the mechanical properties of fast and slow skeletal muscle, including maximum tensile strength, maximum strain, elasticity and energy absorption, gradually stregthen with extended time (not more than 48 hours) after eccentric exercise-induced injury. On the other hand, the maximum strain of slow muscle is higher than that of fast muscle.
