摘要：以健康长寿为视角，采用相关性统计分析等方法，研究20～69岁人群身体素质衰减特征。研究结果：①身体素质促进健康长寿；②成年全期平缓衰减、老年初期加快衰减；③不同身体素质衰减幅度不同，男性身体素质衰减幅度及排序为：柔韧素质83.7%>平衡素质74.8%>速度素质59.1%>力量素质22.7%；女性为：平衡素质77.8%>速度素质60.4%>柔韧素质40.7%>力量素质16.3%；④全周期（20-69岁）身体素质衰减时序为：相对衰减期（20-24岁）、柔韧素质衰减期（25-34岁）、力量素质衰减期（35-39岁）、平衡素质衰减期（40-59岁）、全面衰减期（60-69岁）。我国20-69岁人群身体素质衰减方向、衰减幅度等特征明显。由此建议：遵循衰减特征规律，进一步增强锻炼目的性、针对性，从而更好地促进身体素质全面发展和人的健康长寿。关键词：健康长寿；成年人；老年人；身体素质Abstract:Fromtheperspectiveofhealthylongevity,thispaperanalyzesthecharacteristicsofphysicalfitnessdecayinpeopleaged20-69years,usingmethodssuchascorrelationalstatisticalanalysistoexploreexistingcharacteristicsanddiscussanalysisandrecommendations.Theresultsareasfllows:(a)Physicalfitnesspromoteshealthandlongevity;(b)Theattenuationisgentlethroughoutadulthoodandacceleratedinearlyadulthood;(c)Theattenuationrateofdifferentphysicalfitnessvaries.Theorderoftheattenuationrateofmalephysicalfitnessis:flexibility83.7%>balance74.8%>speed59.1%>strength22.7%;forwomen,thebalancequalityis77.8%,speedqualityis60.4%,flexibilityqualityis40.7%,andstrengthqualityis16.3%;(d)Thetimesequenceofphysicalfitnessdecayacrosstheentirelifespan(20-69yearsold)is:relativedecayphase(20-24yearsold),flexibilitydecayphase(25-34yearsold),strengthdecayphase(35-39yearsold),balancedecayphase(40-59yearsold),andoveralldecayphase(60-69yearsold).Thecharacteristicsofphysicalfitnessdeclineinthe20-69agegroupinChinaareobvious,suchasthedirectionandmagnitudeofdecline.Therefore,itisnecessarytofollowthelawsofphysicalfitnessdeclineandfurtherenhancethepurposeandrelevanceofexercisetobetterpromotethecomprehensivedevelopmentofphysicalfitnessandhumanhealthandlongevity.Keywords:healthylongevity;adults;elderly;physicalfitness群众体育QUNZHONG...
