跳舞过程中人体变化解析

跳舞过程中人体变化解析

跳舞有益于健康，已被世界所公认。但有些具体细节仍有些模糊不清，带着一些问题我们咨询了一些生理学家，得到了较专业的解释和科学依据。

跳舞属中低度有氧运动，每天跳舞一小时对业余舞蹈爱好者和健身者是最合适的选择。据权威人士分析：

从开始跳舞第1~5分钟

跳舞的热身运动会使心率加快、血流增加、肌肉得到预热、关节开始释放润滑液。

从6~10分钟

随着动作加快，血压会轻微上升、心跳可达140/分钟，血液和氧氛会不断对肌肉进行补充，使血管扩张。

从11~20分钟

体内热量增加，呼吸加深、排汗、肾上腺素、胰岛素分泌量上升以满足肌肉的需求。

从21~45分钟

随着舞步的进展，运动量增加和身体能量的释放，大脑皮层会释放“内啡呔”激素，又称“快乐素”，人会感觉心情愉悦，此时通过排汗消耗体内多余的脂肪、胰岛素分泌量开始下降，此时的现象对肥胖、糖尿病患者很有利。

从46~60分钟

此时肌肉开始逐步进入疲劳状态，体内碳水化合物的存储量减少。进行到一小时的时候，不要突然停止，应做适当的整理活动，使心率、呼吸都适当放缓，给体内脏器和骨骼肌肉以缓冲的机会。

每天跳舞一小时，坚持一年以上，您就会得到深切的体会。

您的骨骼肌肉变结实了、心肺功能增加了、身体的免疫力增强了、多余的脂肪消失了、形体越来越好、气色和精神状态会俱佳。
