Excess weight in adult life is an important risk factor for the development of
noncommunicable diseases. On the other hand, aerobic physical exercise programs have been
shown to be important components both in the prevention and control of these conditions.
This work aims to evaluate the effects of moderate intensity training on the body weight
(BW) and food intake (FI) of adult male rats. Wistar rats were obtained at 30 days old.
Throughout the experimental period, they were kept in appropriate cages (4 rats per box)
containing food and water, temperature (22ºC) and photoperiod (07:00 to 19:00) controlled.
At PN 40 they were divided into sedentary (S) and exercised (E) groups. The BW and FI were
measured twice a week, from 40 to 140 days old. Exercised rats performed a moderate-
intensity treadmill running from PN 90 to 120. During this period, they were submitted to an
effort test to evaluate performance and control the training load (55% to 65% VO 2max ). The
results showed that both BW and FI were not altered with the training performed during adult
life, even after 20 days of exercise cessation. More studies are needed in order to assess
whether moderate-intensity training is able to attenuates the deleterious effects observed in
the biometric and metabolic markers of adult rats programmed for obesity and/or metabolic
syndrome.
