Abstract

TIBANA, Ramires Alsamir et al. EFFECTS OF DIFFERENT VOLUMES OF RESISTANCE EXERCISE ON THE FOOD INTAKE OF RATS. Rev Bras Med Esporte [online]. 2018, vol.24, n.2, pp.145-148. ISSN 1517-8692.  http://dx.doi.org/10.1590/1517-869220182402160028.

Introduction:

Physical exercise changes food intake after an acute session; however further research is needed to identify the effects of resistance exercise (RE) with different training volumes.

Objective:

To investigate the effects of acute RE (two sessions) with different training volumes on the food intake of rats.

Methods:

Twenty four Wistar rats were randomly divided into three groups: control group (who did not perform RE; n=8); RE (stair climbing) with four series (G4, n=8) and overload of 50%, 75%, 90%, and 100% of the maximum load capacity of the animal and RE with eight series (G8; n=8) with two increases of each overload of 50%, 75%, 90%, and 100% of the maximum load capacity of the animal. The average amount of ingested feed was measured for each experimental group 24 and 48 hours after the first RE session and 72 hours after the second RE session.

Results:

The food intake of the groups that performed the RE session was significantly lower (p<0.05) when compared to the control group only at 24 hours after the first training session. After the second training session (72 h), the G8 showed a significantly lower food intake (p<0.05) when compared to G4 and the control group. However, the food consumption relative to the body mass of the animals (g/gBM) was significantly lower only after the second training session (72 h) in G8 (p<0.05) compared to G4 and the control group.

Conclusion:

Therefore, the resistance exercise decreases the food intake of rats after an acute session; in addition, a higher training volume seems to be more advantageous. Level of Evidence II; Therapeutic studies - Investigation of treatment results.
