舞蹈啦啦操干预对肥胖女大学生体成分和心血管功能的改善及生物学关系

Effect and Correlation of Dance Cheerleading Intervention on Body Composition and Cardiovascular of Obese College Female Students

目的:探讨舞蹈啦啦操运动干预对肥胖女大学生体成分和心血管功能的影响及干预后体成分与心血管功能指标的相关性。方法:34名肥胖女大学生为实验组(舞蹈啦啦操干预),95min/次,4次/周,共16周,干预前、中、后测试各指标。20名正常女大学生为对照组,实验前测试各指标。结果:干预前,两组指标(CO)差异显著,P<0.001。干预中、前比,指标(WHR、CO、TC、HDL、LDL)差异显著,P<0.05。干预后、中比,指标(CO、HDL、LDL)差异显著(P<0.05、P<0.01)。干预前后,指标(CO)差异显著(P<0.05、P<0.01、P<0.001)。干预后两组比,指标(EF、SV、CO、HR、CO无)差异显著(P<0.05、P<0.01)。W降低与SBP、DBP、TG、TC降低相关,P<0.05。Fat降低与LVET、EF、SV、HDL上升,与HR、SBP、DBP、TG、TC降低相关,P<0.05。Fat%降低与LVET,EF、SV、HDL上升,与SVR、HR、SBP、DBP、LDL、TG、TC下降相关(P<0.05、P<0.01)。WHR下降与TG、TC下降相关,P<0.05。BMI降低与LVET、EF、SV、HDL上升,与SVR、HR、LDL、SBP、DBP、TG、TC下降相关(P<0.05、P<0.01)。结论:舞蹈啦啦操干预能显著改善体成分和心血管功能,长期干预效果好于短期,但部分指标与正常女性仍有一定差异。Fat%、BMI与心血管功能指标变化的等级相关性最高;TG、TC与所有体成分指标相关。

The objective of the study was to reveal the effect and correlation of dance cheerleading intervention on body composition and cardiovascular function of obese college female students. 34 obese college female students were as classi- fied into experimental group and took physical exercise for 95 rain/time, 4 times per week, with a total of 16 weeks. Indexes were monitored before, during and after taking the exercise. 20 other female college students were classified into control group and related indexes were recorded before the exercise intervention. It showed that before the intervention, indicators of the two groups （ CO no） were of no significant difference （P〈0. 001）. During the intervention, WHR, CO, TC, HDL and LDL no were significantly different （P〈0. 05）. After the intervention, CO, HDL and LDL no were greatly different （P〈O. 05,P〈O. 01）. Before and after the intervention, COno was significantly different （P〈O. 05,P〈0. 01, P〈0. 001）. After intervention, EF, SV, CO, HR, COno of both groups differed （P〈0. 05,P〈 0. 01）. W reduction wasrelated to SBP, DBP, TG, TC reduction（P〈0. 05）. Fat reduction was associated with increase of LVET, EF, SV, HDL, and reduction of HR, SBP, DBP, TG and TC （P〈0. 05）. Reduction of Fat % was relevant to increase of LVET, EF, SV, HDL, and to reduction of SVR, HR, SBP, DBP, LDL, TG and TC （P〈0. 05,P〈0. 01）. WHR decrease was related to TG and TC decrease （P〈0. 05）.Reduction of BMI was related to increase of LVET, EF, SV and HDL, and to the decrease of SVR, HR, LDL, SBP, DBP, TG, and TC （P〈0. 05,P〈 0. 01）. It was concluded that dance cheerleading intervention could significantly improve the body composition and cardiovascular function. Long-term intervention proved to have better effect than shortterm intervention. Though some indicators still were different with those of the normal female students, Fat % and BMI were mostly correlated to cardiovascular function indicators. TG, TC were related to all body component index.
