Researchers at McMaster University have found that a single minute of very intense exercise produces health benefits similar to longer, traditional endurance training.
The findings put to rest the common excuse for not getting in shape: there is not enough time.
“This is a very time-efficient workout strategy,” says Martin Gibala, a professor of kinesiology at McMaster and lead author on the study. “Brief bursts of intense exercise are remarkably effective.”
Scientists set out to determine how sprint interval training (SIT) compared to moderate-intensity continuous training (MICT), as recommended in publichealth guidelines. They examined key health indicators including cardiorespiratory fitness and insulin sensitivity, a measure of how the body regulates blood sugar.
A total of 27 sedentary men were recruited and assigned to perform three weekly sessions of either intense or moderate training for 12 weeks, or to a control group that did not exercise).
The McMaster team has previously shown that the SIT protocol, which involved three 20-second ‘all-out’ cycle sprints, was effective for boosting fitness. The workout totaled just 10 minutes, including a 2-minute warm-up and 3-minute cool down, and two minutes of easy cycling for recovery between the hard sprints… Read More>>
