Taking break while exercising helps diet
TOKYO (UPI) -- A Japanese study showed taking a break in the middle of
an exercise workout may metabolize more fat than exercising without
The study, published in the Journal of Applied Physiology, compared
one single 60-minute bout of exercise to two bouts of 30-minute
exercise divided by a 20-minute rest.
"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," lead researcher Kazushige Goto of the
University of Tokyo, said in a statement.
Seven healthy, physically active men with an average age of 25
exercised on a cycling machine and rested in chairs. Their respiratory
gas and heart rates were monitored continuously.
Trials with the break showed a greater amount of lipolysis -- fat
breakdown -- than did the no-break trials. The trial with the break
also had a pronounced increase in the final 15 minutes of exercise of
free fatty acids and glycerol -- chemical compounds released when
stored fat is used, the study said.
