Throughout the experiment, the body weightevolution of the groups and the final average body weight are shown in Fig. 3 and Table2, respectively. Confirming that animals initiated the experiment with similar healthstatus, no significant (p > 0.05) difference was observed in the initial body weightamong the groups (Table 2). After 8 and 12 weeks of experiment, all groups showedsignificant (p < 0.05) body weight gain (∆%) (Fig. 3 and Table 2); the values were21.7%, 26.2%, 30.8% and 33.5% in the T8, C8, T12 and C12 groups, respectively(Table 2). These values were not statistically (p > 0.05) different among all groups.Table 2.

C8, 8 weeks control; T8, 8weeks trained; C12, 12 weeks control; and T12, 12 weeks trained. *Significant difference compared to their initial body weight at p< 0.05.The similar progression of PC in both trained and control groups demonstratedthat the training model used, although intense, did not subject the animals to state ofovertraining. The data show that the increase in body weight reflected only the somaticgrowth of animals, given that they began the experiment in the young phase. Consistentwith no significant (p > 0.05) change in body weight, resistance training did notpromote significant (p > 0.05) alteration in food intake in the T8 and T12 groupscompared to the C8 and C12 groups, respectively (Figure x).53
