Performing repeated bouts of high-intensity "sprint"-type exercise resulted in profound changes in skeletal muscle and endurance capacity, similar to training that requires hours of exercise each week.

Just six minutes of intense exercise a week could be as effective as an hour of daily moderate activity suggests new findings from researchers at McMaster University.

"Short bouts of very intense exercise improved muscle health and performance comparable to several weeks of traditional endurance training," says Martin Gibala, an associate professor in the department of kinesiology of McMaster.

The research is published in the June edition of the Journal of Applied Physiology.
