In a study published in Medicine & Science in Sport & Exercise the researchers studied a group of 20 participants who were divided into two groups — sprinters and runners. Both the sprint group and the running group trained three times a week for six weeks. Sprinters performed “all-out” maximum sprints of 30-seconds, 6-repetitions, with 4-minute rest periods between each repetition. The runners ran for 30-60 minutes each training session at 65% of their VO2 max (VO2 max is a measure of the intensity of an aerobic exercise). At the end of 6-weeks the runners averages a 5.8% decrease in fat mass, while the sprinters lost 12.4%!
So what does this limited study show us? While this study by itself doesn’t prove much, it does suggest that exercising at higher intensity levels for shorter durations definitely can have a beneficial effect of body fat loss. Interval or high-intensity training MAY have a place in your workout plan, but because it involves higher intensity cardio work, you should always check with your physician first, AND seek the advice of an experienced and certified personal trainer or strength and conditioning professional.
Just another bit of information to add to your arsenal!
