Effect of tension and metabolic resistance training on the body composition of healthy young people

Abstract

Concerns about health are becoming more and more evident as people seek to exercise to escape a sedentary lifestyle and gain muscle mass. Gaining mass requires an elaborate strength training program, such as increasing strength and muscle mass, as well as reducing the percentage of fat and improving exercise performance. The aim of this study was to evaluate the advantages of resistance training using tension and metabolic stimuli, offered by means of an extension chair on the quadriceps femoris muscle. A descriptive study with a quantitative approach was carried out to assess body composition and maximum strength measured by one repetition maximum (1RM). The results show 5 individuals (n=5), all male, with an average age of 23.41 ± 2.87 years and a BMI of 23.62 ± 1.48 kg/cm2. After two months of physical training, with intensity between 30% and 80% of 1RM and volume ranging from 3 to 5 sets of 8 to 20 repetitions, a slight reduction was found in the group average values, where at the start of data collection the values were 80.88kg ± 12.9kg and after two months it evolved to 80.5kg ± 12.5kg with a significance index of p= 0.5. It can be concluded that a good periodization of training and a weekly frequency will generate gains for exercisers.
