Question:

What is microtrauma?  Is it beneficial or harmful?


Answer:

Repetitive and or chronic loading of muscle during exercise produces microtrauma to the tissue. Eccentric strengthening exercises (muscle contracts while it is lengthening) tend to produce more tissue microtrauma. Microtrauma, within acceptable limits, stimulates muscle to rebuild and adapt to the increasing load thus increasing the strength of the muscle. However, too much too soon and not enough rest can affect the balance and potentially lead to an injury.
