An Experimental Study On The Effects Of Different Core Strength Training On The Core Muscle Strength Of Middle - Aged Women

Objective: through research of intervention effect of core strength by different core strength trainings on middle-aged women, and analyzing the effect of core strength indicators by these three trainings on middle-aged women by using landscape contrast, to expect to provide theoretical basis for middle-aged women choosing more suitable, scientific and effective core strength training. Methods: Collecting voluntary and healthy middle-aged women between 45-59 years old in the communities near Chengdu Sports University who have the exercise habit. Flitering 37(53.6±4.7years) subjects through the questionnaire on health fitness before exercise and PAR-Q. They were randomly divided into three experimental groups, the Pilates(N=10), the Swiss ball(N=10), the balance soft tread(N=9), and one control group(N=8). Confirming the final experimental group training plan, based on the preliminary experiment and combined with RPE. The control groups weren’t taken any form of core strength trainings; they can exercise by usual habit. Experiment Site: the health building of Chengdu Sports University. The experimental groups were taken core strength trainings during 19:00-20:30 on every Monday, Wednesday and Friday on the third floor of Health Building at Chengdu Sport University, a total of 8 weeks. The subjects were taken height and weight, Troso(Germany) and premier level of eight abdominal bridge tests before and after the experiment. Gaining ?X±S by using SPSS 16.0, then processing the datas with T test and one-way ANOVA. Results:(1) after eight weeks of pilates core strength training, compared with before(1.09±0.13), the subjects’ flexion strength of spinal muscle(1.17±0.85) increased with significant difference(P<0.05). The extension strength of spinal muscle(0.93±0.07) and premier level of eight abdominal bridge(114.96±43.02s), compared with the previous data 0.76±0.17 and 22.24±9.71 s, has very significant difference(P<0.01);(2) after eight weeks of swiss ball core strength training, the subjects’ flexion strength of spinal muscle(1.09±0.11) and premier level of eight abdominal bridge(56.48±34.34s), compared with the previous data 0.83±0.41 and 26.34±9.45 s, has significant difference(P<0.05). Compared with before(0.66±0.22), the extension strength of spinal muscle(0.94±0.07) improved with very significant difference(P<0.01);(3) after eight weeks of balance soft tread core strength training, the subjects’ flexion and extension strength of spinal muscle has a very significant difference(P<0.01). Compared with before(28.67±11.63s), the premier level of eight abdominal bridge(82.78±21.53s) has very significant difference(P<0.01);(4) After the experiment, compared the pilates group with the Swiss ball group, the pilates’ level of the premier level of eight abdominal bridge(114.96±43.02s) is obviously higher than the Swiss ball groups’(56.48±34.34s)(P<0.01);(5) After the experiment, compared the pilates group with the balance soft tread group, flexion and extension strength of spinal muscle has a very significant difference(P<0.01), and the balance soft tread is higher than the pilates;(6) After the experiment, compared the Swiss ball group with the balance soft tread group, flexion strength of spinal muscle, the swiss ball(1.09±0.11), the balance soft tread(1.57±0.32), has a very significant difference(P<0.01). The extension strength of spinal muscle, the swiss ball(0.94±0.07), the balance soft tread(1.02±0.06), has a significant difference(P<0.05). Conclusion:(1) These three core strength trainings all can effectively improve the flexion and extension strength of spinal muscle of the middle-aged women;(2) The pilates core strength training is superior to Swiss ball core strength training on improving the strength of transverse muscle of abdomen, straight muscle of abdomen, internal oblique, et al;(3) The balance soft tread core strength training is superior to pilates core strength training on improving the flexion and extension strength of spinal muscle;(4) The balance soft tread core strength training is superior to Swiss ball core strength training on improving the strength of gluteus maximus, et al.
