A few 30 second sprints as beneficial as hour long jog

Hamilton, ON. June 1, 2005 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, which is published in the June edition of the Journal of Applied Physiology, found that 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.

The study was conducted on 16 subjects: eight who performed a two-week sprint interval training program and eight who did no exercise training. The training program consisted of between four and seven 30-second bursts of "all out" cycling followed by four minutes of recovery three times a week for two weeks. Researchers found that endurance capacity in the sprint group increased on average from 26 minutes to 51 minutes, whereas the control group showed no change. The muscles of the trained group also showed a significant increase in citrate synthase, an enzyme that is indicative of the tissue's ability to utilize oxygen.

"Sprint training may offer an option for individuals who cite "lack of time" as a major impediment to fitness and conditioning," said Gibala. "This type of training is very demanding and requires a high level of motivation, however less frequent, higher intensity exercise can indeed lead to improvements in health and fitness."
