Incorporating bursts of speed into a workout plan can have big benefits in improving strength, endurance, power and overall health – not only for athletes but others too.
According to researchers of the McMaster University in Hamilton, Ontario, even those who are obese or suffering from health problems like metabolic syndrome or pre-diabetes — can benefit from high-intensity interval training.
They found that 16 overweight and obese women — with body mass indexes above 25 – lost abdominal and leg fat although their weights did not fall after they followed high-intensity plan for six weeks. But, their muscle biopsies showed changes at the cellular level that increase metabolism, or how the body burns energy.
One hour of high-intensity intervals in a week is as healthful as longer more moderate exercise, but former is ahead than the later in stimulation of the body’s metabolism.
High Intensity training (HIT) is a form of progressive resistance exercise marked by a high level of effort. It is relatively a brief and infrequent workout, as compared to physical training methods involving low to moderate levels of effort and longer, more frequent workouts.
The study was published in the Obesity journal.
