microtears
Pronunciation: MY-kro-teerz
Microscopic damage to muscle or tendon fibers that occurs during intense exercise or overuse.
Full Definition
Microtears refer to small-scale disruptions in muscle or tendon fibers that occur at the cellular level during strenuous exercise or repetitive loading. These microscopic injuries are part of the normal adaptation process in response to training stimuli and typically heal within 24-72 hours when adequate recovery is provided. However, when microtears accumulate faster than the tissue can repair, they can lead to more significant injuries such as muscle strains or tendinopathies. Understanding the concept of microtears is crucial for developing appropriate training loads and recovery protocols in athletic populations.
Usage
Usage note: Distinguish from clinical muscle strains which involve larger tissue disruption.
