Sprinting, not jogging, helps men lose harmful belly fat faster. Eight-second bursts of sprinting on an exercise bike repeated intermittently for 20 minutes, 3 times per week, helped overweight men lose 4 pounds of body fat over 12 weeks.
My comment: this data contradicts previous data supporting the notion that longer duration not higher intensity exercise is more efficient & effective at weight loss. The sprinting described was part of a 2o minute exercise program (8 s sprint, 12 s recovery). Interestingly the investigators had subjects sprint to achieve a heart rate which was 80 - 90% of their maximum predicted heart rate, which would qualify as higher but not highest intensity exercise.
