The Efficiency of Different Strength Training on Body Composition and Quality of Life in Overweight Women. The aim of research work: To estimate the efficiency of different strength training on body composition and quality of life in overweight women. Research Tasks: 1. To determine different strength training effects on body composition, strength endurance and quality of life in overweight women. 2. To compare the efficiency of different strength training on body composition, strength endurance and quality of life in overweight women. Methods and implementation: The research was conducted in community of Vilnius region and Vilnius University Faculty of Medicine, The Department of Rehabilitation, Physical and Sports Medicine Cathedral since of November 2016 till February 2017. In order to conduct this research, the ethical approval from research ethics committee in Vilnius University had been received. The participants had been informed about the research and their anonymity had been guaranteed. While carrying out the research, all the labour safety requirements were met. A total of 50 overweight women were randomly divided into two groups: 25 in the first group and 25 in the second. The groups were homogeneous (p≥ 0,05) by the age and BMI. In order to estimate the efficiency of different strength training on body composition body mass index, measured skin folds and parts of the body size were used. The internal body fat, percentage mass of fat and muscle were assessed using body composition analyzer. Quality of life assessment was applied to the selected SF - 36 quality of life questionnaire. In order to estimate strength endurance Mc Gill, squats and upper extremity stability tests were used. Statistical analysis of the data was carried out. The data was processed using Microsoft Excel for Mac and IBM SPSS 24.0 for Mac software. Results: The study revealed that traditional strength training and strength training workout in a large number of repetitions of the exercise had a positive effect on BMI and internal body fat reduction (p < 0.05), but no statistically significant difference between the groups was found. The study revealed that the percentage mass of fat almost 3 percentage it was significantly lower in the first group that had the traditional strength training workout. The analysis of body size and fat folds of the skin shows a statistically significant decrease in both groups. The study shows that strength endurance in the first group and the second group significantly increased in comparison to the rezults of upper extremity stability, squats and Mc Gill tests (p < 0,05). Having compared the groups with each other, endurance of torso muscle was significantly higher in the second group. The assessment of the quality of life results did not show any statistically significant differences while comparing the groups (p ≥ 0,05). Conclusions: 1.The positive side of different strength training effects on body composition (p < 0,05), strength endurance (p < 0,05) for the first and the second groups were determinated. For the assessment of quality of life, it was found that the traditional strength training significantly improved physical activity, pain, general health and emotional state (p <0,05); strength training workout using a large number of repetitions of the exercise improved overall health, energy / vitality, and emotional state (p < 0.05). 2.Comparing the results of the second test between the groups it was found that the traditional strength training group was effective in reducing the percentage mass of fat (p < 0,05); strength training workout in a large number of repetitions of the exercise was effective in reducing subscapular skinfold thickness (p < 0,05), and increasing torso muscle endurance (p <0,05). |
