由本研究之結果發現,心血管疾病高危險群婦女之危險因子,除以停經者為最多 (66.8%)外,其收縮壓、BMI、血清總膽固醇濃度平均值亦有偏高現象,此外,是否停經 與婦女血清總膽固醇及LDL-C 濃度具顯著相關性(r=0.24, p=0.03; r=0.29, p=0.01),而研 究者於另一項研究中亦發現,BMI 偏高及血脂異常為冠狀動脈疾病婦女疾病嚴重程度之 重要預測因子(蔡,2003),故針對國內婦女群體之 BMI 和血脂分佈情形,及其改善措施 進行深入探討是非常重要之工作。
在運動訓練強度方面,門診走步機運動訓練組較高於居家步行運動組(79.8% vs.
70.4% peak HR),故參與門診走步機運動訓練之婦女身體有氧功能增加顯著優於控制組 之變化(p=0.02);而居家運動組婦女有氧功能雖然也有增加的趨勢,但相較於控制組之變 化,並未達顯著差異(p=0.32)。
此外,三組婦女平均BMI 及收縮壓於計劃前後具有顯著交互作用,其中門診走步機 運動組BMI 改善優於居家運動組,而居家運動組平均收縮壓降低則有優於門診運動組之 趨勢。然運動訓練措施對婦女血脂肪濃度及血糖值之改善並未呈現顯著之成效,由以上 資料分析之結果,提供以下三點建議:
一、針對中年婦女之運動訓練計劃,平均達80% peak HR 之運動訓練強度,對於婦女 BMI 及身體有氧功能之改善為佳;而70% peak HR 之運動訓練強度,則對婦女收縮壓之 控制有較好的效果。
二、婦女血脂肪濃度的改善,宜再增加飲食控制之介入,來觀察其血脂之變化,並與藉 由運動促進措施之成效加以比較及分析。
三、未來針對停經期婦女血脂肪濃度之變化(尤其血清總膽固醇及 LDL-C 濃度)及其相關 因素,宜再深入進行研究加以探討。
