The aim of the study was to analyze and compare gains of strength muscle and to observe the behavior of the subjective perception of pain (SPP) in the period eight weeks in sedentary women through two different programs from resistive exercises. The study was composed of 16 women (27.5 ± 4.8 years; 57 ± 3.9 kg; 162.8 ± 3.3 cm; 21.4 ± 1 kg/m2) healthy and sedentary. They were separate in two different groups: group 1 (G1) - during two initial weeks accomplished two sets of 10 repetitions with load that varied of 40 to 60% of the mass weight. However, 3th and 4th weeks they executed three sets of 10 repetitions to 80% of 1RM. Among 5th and 8th weeks it happened progressive increase of the set number for four maintaining the number of repetitions (10 repetitions) and same overload value; group 2 (G2) - program continuous in the exercise training of three sets of 10 repetitions was accomplished in the first two weeks with a load that varied of 40 to 60% of the corporal weight. Subsequent weeks the training was altered for four sets of 10 repetitions with an equivalent load to 80% of 1RM along the eight weeks of training. For analysis of the strength muscle the test of 1RM was used in the end of 2nd, 4th, 6th and 8th weeks with intention of to verify the behavior of the strength muscle starting from the displacement of loads and to optimize the training load. The exercises used in the training protocol and in the test of 1RM they were: leg press 45°, knee extension, knee flexion, lat pull down, elbow flexion, elbow extension. SPP was presented to each volunteer 48:00h after accomplishment of the test of 1RM. ANOVA Two Way following by the test post hoc of Bonferroni verified that the results intra-groups for G1 presented significant difference for all of the exercises in all the tests. However, G2 the significant difference was observed, in a large part of the exercises, only of the 3° and 4° test in relation to the 1° test. For the analyses inter-groups the test Mann-Whitney for independent samples verified increase significant of strength muscle in the G1 in relation to G2 with exercises leg press 45°, elbow flexion, elbow extension. In relation to SPP a significant fall was observed in the analogical scale of G1 in relation to G2 (p <0.001). The conclusion revealed that the progressive overload imposed G1 promoted increased gains of muscle strength than G2.
