G1-Three sets of exercise
G2-One set of exercise
G3-Control
G1 group - the participants will perform three sets of 15-20 repetitions of the trunk extensor exercise on a roman chair machine with the hips at 45 degrees relative to horizontal; performing trunk flexion-extension cycles for a total of 4 seconds (2 s concentric and 2 s eccentric contraction). The relative load for initial training will be placed at 20% back maximal voluntary contraction (MVC) and will be progressive during the training. The time session of training will be of 10 weeks.
G2 group - the participants will perform only one set of 15-20 repetitions of the trunk extensor exercise on a roman chair machine with the hips at 45 degrees relative to horizontal; performing trunk flexion-extension cycles for a total of 4 seconds (2 s concentric and 2 s eccentric contraction). The relative load for initial training will be placed at 20% back maximal voluntary contraction (MVC) and will be progressive during the training. The time session of training will be of 10 weeks.
G3 group - the participants will be the control group, which not participating of exercise program in any time during the study.
