The Effect of Different Strength Training on Capacity and Cognitive Function in Overweight Women The aim of research work: to determine the impact of different strength training to physical performance and cognitive functions in overweight women. Tasks of work: 1. To evaluate and compare effects of different strength training in overweight women on cardiovascular capacity, muscular strength and endurance strength after 6 weeks. and after 12 weeks the duration. 2. To evaluate and compare effects of different strength training in overweight women on cognitive functions: attention, concentration and executive function after 6 weeks. and after 12 weeks. the duration. Methods of research. This randomized clinical research was performed during November, 2016 – February, 2017. Research group consisted of fourty-three women with overweight, for whom functional capacity parameters on cardiovascular capacity (using Harvard Septest index), muscle strength (using a dynamometer), strength endurance - closed kinematic chain upper extremity stability test, landing-station test and McGill endurance evaluation tests were assessed. Cognitive parameters were tested using Trial Making test and Stroop test. Statistical data analysis was performed using Excel 2010 and SPSS for Windows 22.0 software packages. Results. thirtynine volunteers were divided into I experimental group (n = 21), which had traditional resistance training and II experimental group (n = 18), which had the resistance training to muscle failure. In both groups cardiovascular strength, muscle strength and endurance strength improved significantly (p <0.05) both and after 6 weeks and after 12 weeks the duration. Significant difference between groups were identified for the lateral trunk muscle endurance after 12 weeks. Effect sizes were greater in the II-d experimental group (12.92 ± 2.04 sec.) than in the I-st experimental group (10.49 ± 2.67 sec.) (p <0.05). Cognitive parameters for both groups (attention and concentration, executive function) were improved statistically significant on Trial Making Test and Stroop test after 6 weeks and after 12 weeks duration (p <0.05). Trial Making Test showed significant difference between-groups both after 6 weeks and after 12 weeks the duration and was greater in group II (9.5 ± 0.06 sec.) than the I-th group (4.88 ± 0.11 sec.). The difference in results on Stroop test were statistically significant between-groups after 6 weeks duration. After 12 weeks the difference between-groups was a statistically significant higher in group II (11.33 ± 0.76 sec.) than the I-th group (6.42 ± 0.1 sec.) (p <0.05). Findings: Traditional resistance training and resistance strength training to muscle failure significantly improves on cardiovascular capacity, muscle strength and muscle endurance power in overweight women after 6 weeks and after 12 weeks the duration. Statistically significant difference was identified between-groups after 12 weeks of training-term in evaluation of the side trunk muscle strength endurance (p <0.05). Traditional resistance training and resistance strength training to failure improves cognitive function parameters (p <0.05). The significant change were observed after 6 weeks and after 12 weeks the duration of the study. Comparing the results between-groups significantly greater cognitive change (concentration of attention, executive function) was determined on II-d experimental group than I-st experimental group after 6 weeks training-term and after 12 weeks the duration. |
