ABSTRACT
BACKGROUND/

OBJECTIVES:

Successful recovery of an animal from exercise is essential, especially prior to the next exercise session. This study was conducted to find an effective exercise-to-rest period ratio for the restoration of energy sources and replenishment of anti-oxidative status in tissue after exercise. MATERIALS/

METHODS:

Thirty-two rats were assigned to either non-training or training exercise groups for 5 weeks. After that period, the two groups were subdivided into four smaller groups non-exercise (NE), exercise 0.5 hour and rest 1 hour (ER0.51), exercise 1 hour and rest 1 hour (ER11), exercise 2 hours and rest 1 hour (ER21).

RESULTS:

In the training group animals and compared to the NE group, the levels of plasma glucose after the rest period were significantly high in all ER groups but highest in the ER21 group. Similarly, the liver glycogen level was highest in the ER21 group. The plasma FFA level reached the highest level in the ER21 group but was similarly high in the ER0.51 group. Liver TG level was unchanged in the ER21 and ER11 groups but was significantly high in the ER0.51 group. Muscle TG levels were decreased in all three ER groups. Plasma protein levels were significantly high in the ER21 and ER0.51 groups. In both training animal and non-training animals, the liver protein levels did not change significantly between the NE and ER groups, irrespective of the exercise-to-rest ratio. In the training animal group, muscle protein level was significantly low in the ER21 and ER0.51 groups. The activity levels of superoxide dismutase and catalase, as well as the malondialdehyde concentration, were not significantly different between NE and ER groups, irrespective of the exercise-to-rest period ratio.

CONCLUSIONS:

These results indicate that animals provided with a 0.51 to 11 exercise-to-rest period ratio can restore their muscle energy sources and recover their anti-oxidative defense system.
