摘 要：社會(huì)的快速發(fā)展，對(duì)當(dāng)代大學(xué)生各方面的素質(zhì)有了更高的要求。除了專業(yè)知識(shí)外，學(xué)生的身體素質(zhì)同樣值得關(guān)注。擁有強(qiáng)健的體魄是社會(huì)對(duì)每人的基本要求。大學(xué)生體質(zhì)健康測(cè)試是促進(jìn)學(xué)生體質(zhì)健康發(fā)展，激勵(lì)學(xué)生積極進(jìn)行身體鍛煉的教育手段。學(xué)生體質(zhì)測(cè)試，是促進(jìn)大學(xué)生養(yǎng)成體育鍛煉的習(xí)慣、不斷增強(qiáng)體質(zhì)健康的重要方法。 主成分分析是利用降維的思想，在損失很少信息的前提下把多個(gè)指標(biāo)轉(zhuǎn)化為幾個(gè)綜合指標(biāo)的多元統(tǒng)計(jì)方法．通過主成分分析法，在收集了本校2011年的體能測(cè)試數(shù)據(jù)的基礎(chǔ)上，利用本校學(xué)生體質(zhì)測(cè)試項(xiàng)目：身高、體重、肺活量、握力、臺(tái)階、立定跳遠(yuǎn)，找出控制這些指標(biāo)的主要因素，根據(jù)各個(gè)主成分的貢獻(xiàn)率計(jì)算出各體測(cè)項(xiàng)目的綜合得分，按照得分的高低對(duì)學(xué)生體質(zhì)綜合評(píng)價(jià)進(jìn)行排名，并對(duì)評(píng)價(jià)結(jié)果進(jìn)行分析，找出他們之間存在差異的主要原因，科學(xué)地指導(dǎo)大學(xué)生鍛煉身體。 關(guān)鍵詞：大學(xué)生 體能測(cè)試 主成分分析
