核心部位整体性意识在健身健美操动态姿势中的应用研究

Application Study of Core Position as Integration Consciousness in Dynamic Posture of Aerobic Exercise

目的探讨在健身健美操动态姿势中建立核心部位整体性意识的健身效应。方法将72人随机分为4组A(跳操)组、B(跳操+意识)组、C(跳操+力量)组、D(跳操+意识+力量)组,进行为期6个月的健身训练。在训练前、后对各组骶棘肌肌电指标、形态指标、素质指标等进行测试。结果B、D组在30s、60s时段波幅的增加及时程的降低较训练前具有非常显著性意义(P<0.01);B组在胸围、腰围、腹部皮脂3项指标的降低较A、C组具有显著性意义(P<0.05),D组训练后较C组同指标而言有显著差异(P<0.05)。D组在闭眼单脚站立、仰卧起坐、纵跳等3项指标的变化具有非常显著性变化(P<0.01)。B、D组对结果的满意度较高。结论采用核心部位整体意识进行健身健美操锻炼,能有效地锻炼腰腹部,增加骶棘肌肌力,改善形态指标,提高身体素质。

The purpose of this study was to discuss the effect of establishing core position as integration consciousness in dynamic posture of aerobic exercise. Seventy-two subjects were divided into four groups randomly. Group A of aerobic exercise,group B of aerobic and consciousness exercise,group C of aerobic and strength exercise and group D of aerobic, consciousness and strength exercise for six month fitness training. The result showed that group B and D increased the amplitude of EMG of extensors and reduced the duration of EMG of extensors significantly after training. Changes of shape index revealed that group B was significantly decreased comparing with group A and C on the index of chest circumference,waist circumference and abdomen. Group D changed significantly on three indexes including single foot standing with eye closing, sit-up and jumping. It concludes that core position integration consciousness in aerobic exercise can effectively train the chest and waist, improve shape index and physical fitness.
