A Muscular Strain Occurs When the Load Applied to a Muscle

A muscular strain occurs when the load applied to a muscle exceeds the tissue tolerance and is most often associated with eccentric muscle activity. What two factors are positively correlated with the magnitude of tissue damage?

A) Number of fibres being contracted while under passive stretch and rate of loading of the eccentric force.
B) Cross sectional area of the muscle and magnitude of load.
C) Amount of blood flow and range of motion.
D) None of the above.
