Why High Intensity Interval Training Can Match Endurance Training

Short bursts of just a few minutes of exhausting physical activity can prepare muscles to work harder, boosting the production of new mitochondria (powerhouses of the cells, generating the energy that our cells need to do their tasks), which culminates endurance enhancement much like more time consuming endurance training.

The research included male subjects who cycled for 30 seconds for maximum-exertion, followed by 4 minutes of rest and repeat this routine 6 times altogether. Twenty-four hours after the test, tissue samples of their thigh muscles were taken and revealed an increased rate of free radicals, showing that just a few minutes of intense exercise is all it takes for benefits to kick in.
