Resting Between Workouts Burns More Fat
between workouts can be more beneficial than one continuous workout,
according to a study by researchers at the University of Tokyo.
With a break
in the middle of a workout, there is an increase in lipolysis, or fat
breakdown. Results also show that a greater amount of free fatty acids
and glycerol were released when there was a rest in between.
lipolysis may be due to a higher level of epinephrine and lower level
of insulin that occurred in those who rested, the study said.
compared two methods of exercise: one 60-minute session versus two
30-minute sessions. Seven men performed each method in three trials.
In the first trial, the men used a cycling machine for an uninterrupted period of 60 minutes, followed by a 60-minute rest.
trial had the men undergoing 30 minutes of the same exercise followed
by a 20-minute rest. The men then cycled for an additional 30 minutes,
and completed the trial with a 60-minute recovery, according to the
American College of Sports Medicine recommends an exercise period of 45
to 60 minutes, the study results found that dividing the session into
smaller ones burn more fat.
findings will be informative about the design of [future] exercise
regimens," said lead researcher Kazushige Goto, Ph.D of the University
