Comparison of aerobic training before and after training resisted for the reduction of percentage of fat in young women initiating in musculation

Abstract

Introduction: According to the World Health Organization, in 2025 there will be 2.3 billion overweight and 700 million obese people. A sedentary lifestyle is a major factor for this increase. Objective: To compare the difference between performing aerobic training before and after resistance training to reduce the percentage of body fat in young women. Materials and methods: 14 women participated in this study, mean age 20.7 ± 3.0 years, BMI 27.1 ± 3.55 km / m² with fat percentage 30.0 ± 2.82. The women were divided into two groups that performed 20 minutes of running with Interval intensity before (TRAA) and after (TRDA) from a protocol of eight exercises against resistance for 12 weeks. Also lactate samples were taken at different sessions. Results: In TRAA group, there was an increase of 0.3kg in total body mass, decreased by 2.09% fat percentage (P> 0.12) equivalent to a loss of 0,69kg adipose tissue and increased 2,61kg of muscle mass. All values without significant differences. In TRDA group 0,29kg there was increase in total body mass, fat percentage decreased 1.24% (p> 0.34), in kilograms, 0,94kg, and muscle mass increased 1,71kg between final evaluation and initial. Conclusion: It is concluded that there was no significant difference between the two groups in the percentage of body fat (p> 0.27) between the initial and final evaluations of the experimental protocol, but there was an increase in muscle mass.
