Abstract

Exercises made from concentric and eccentric contractions in cases of physical training and rehabilitation are able to generate cardiovascular, clinical, biochemical and functional adaptations, characterizing the efficiency of the training process. However, studies comparing the two types show differences between them. Taking into consideration the cost benefit of both types of exercise, is considered as important to undertake research on the relationship between these markers to gain muscle strength produced by both jobs. Thus, the purpose of this study will analyze and compare the cardiovascular, biochemical, clinical and functional variables characteristics of healthy subjects, physically active, after 10 sessions of strength training muscle groups with a predominance of eccentric vs. concentric contraction. The casuistry of the study will consist of 80 subjects, divided equally into four groups (2 groups: concentric and eccentric training and 2 control groups: concentric and eccentric). Volunteers will undergo 10 training sessions for 3 consecutive weeks and the initial load composed of 3 sets of 8 repetitions, the third session of 3 sets of 6 reps, the fifth by 3 sets of 4 repetitions, the seventh by 3 sets of 2 reps and ninth in 3 sets of 1 repetition, 100% of 1RM. The control group hold a single session, which corresponds to 3 sets of one repetition of 100% of 1RM. The collections of the cardiovascular, biochemical, clinical and functional variables occur during the sessions and their ranges and after the end of the training.Exercises made from concentric and eccentric contractions in cases of physical training and rehabilitation are able to generate cardiovascular, clinical, biochemical and functional adaptations, characterizing the efficiency of the training process.
