Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, according to a recent study in Japan .

Researchers conducted the first known study to compare these two exercise methodsexercising continually in one long bout versus breaking up the same workout with a rest period. The findings could change the way we approach exercise. Who wouldnt want to take a breather for that"

Many people believe prolonged exercise will be optimal in order to reduce body fat, but our study has shown that repetitions of shorter exercise may cause enhancements of fat mobilization and utilization during and after the exercise.

These findings will be informative about the design of [future] exercise regimens, said lead researcher Kazushige Goto, Ph.D. Most people are reluctant to perform a single bout of prolonged exercise. The repeated exercise with shorter bouts of exercise will be a great help [in keeping up with fitness].

This finding is part of a study entitled Enhancement of fat metabolism by repeated bouts of moderate endurance exercise, found in the June 2007 edition of the Journal of Applied Physiology, which is published by the American Physiological Society.

Summary of Methodology The researchers used seven healthy (avg. body mass: 66.1, percentage fat: 17.6) men with an average age of 25 who were physically active and familiar with exercise and had them perform three separate trials:

one single bout of 60-min exercise followed with a 60-min recovery period (Single) two bouts of 30-min exercise with a 20-min rest after the first 30-min bout, along with a 60-min recovery period at the end (Repeated) one 60-min rest period (Control)

The men performed each trial at the same time of day after fasting overnight. They exercised on a single ergometer (cycling machine) at the commonly recommended exercise prescription of 60% maximum o
