目的：研究当代黎族青年的体质特征，为少数民族地区体育卫生服务提供基础参考理论。方法应用SPSS17.0软件对590名(其中男性290人，女性300人)黎族青年各类相对体质指标建立R聚类矩阵模型，并与本地600名同龄汉族青年(其中男性300人，女性300人)三项身体形态机能指标相比较，描述当代黎族青年的体质特征。结果经R聚类矩阵分析，黎族男青年各体质派生指标聚为两类。身高/坐位体前屈、体重/坐位体前屈与肺活量/体重、肺活量/台阶指数聚为第一类，身高/立定跳远、体重/立定跳远、体重/身高与台阶实验聚为第二类，黎族女青年各体质派生指标聚为两类。体重/身高、体重/立定跳远与身高/坐位体前屈、体重/坐位体前屈及台阶试验聚为第一类，肺活量/体重、肺活量/台阶指数与身高/立定跳远聚为第二类。通过与本地汉族青年三项身体机能派生指标的比较，体重(kg)/身高(cm)×1000指数值，男女青年黎族都显著高于汉族，差异均有统计学意义(P男<0.01；P女<0.05)，肺活量(m1)/体重(kg)指数值比较差异均无统计学意义(P>0.05)。台阶试验指数黎族青年显著大于汉族青年，差异均有统计学意义(P男<0.01；P女<0.05)。结论黎族男青年第一聚类体质指标体现身体长度、重量对人体屈伸度的影响及其与身体心肺机能潜在的联系；第二聚类体质指标体现身体高度、重量、等长重量及摄氧机能水平对跳跃能力影响的内在关系。黎族女青年第一聚类体质指标体现身体等长重量对身体屈伸度和跳跃素质的影响及其与身体心肺机能的潜在联系；第二聚类体质指标体现身体心肺机能水平对身体等长跳跃远度素质间直接影响。黎族男女青年较本地汉族青年身体形态机能派生指标相比较，具有身体形态相对较充实，身体心肺机能水平相对强的体质特征。目的：研究噹代黎族青年的體質特徵，為少數民族地區體育衛生服務提供基礎參攷理論。方法應用SPSS17.0軟件對590名(其中男性290人，女性300人)黎族青年各類相對體質指標建立R聚類矩陣模型，併與本地600名同齡漢族青年(其中男性300人，女性300人)三項身體形態機能指標相比較，描述噹代黎族青年的體質特徵。結果經R聚類矩陣分析，黎族男青年各體質派生指標聚為兩類。身高/坐位體前屈、體重/坐位體前屈與肺活量/體重、肺活量/檯階指數聚為第一類，身高/立定跳遠、體重/立定跳遠、體重/身高與檯階實驗聚為第二類，黎族女青年各體質派生指標聚為兩類。體重/身高、體重/立定跳遠與身高/坐位體前屈、體重/坐位體前屈及檯階試驗聚為第一類，肺活量/體重、肺活量/檯階指數與身高/立定跳遠聚為第二類。通過與本地漢族青年三項身體機能派生指標的比較，體重(kg)/身高(cm)×1000指數值，男女青年黎族都顯著高于漢族，差異均有統計學意義(P男<0.01；P女<0.05)，肺活量(m1)/體重(kg)指數值比較差異均無統計學意義(P>0.05)。檯階試驗指數黎族青年顯著大于漢族青年，差異均有統計學意義(P男<0.01；P女<0.05)。結論黎族男青年第一聚類體質指標體現身體長度、重量對人體屈伸度的影響及其與身體心肺機能潛在的聯繫；第二聚類體質指標體現身體高度、重量、等長重量及攝氧機能水平對跳躍能力影響的內在關繫。黎族女青年第一聚類體質指標體現身體等長重量對身體屈伸度和跳躍素質的影響及其與身體心肺機能的潛在聯繫；第二聚類體質指標體現身體心肺機能水平對身體等長跳躍遠度素質間直接影響。黎族男女青年較本地漢族青年身體形態機能派生指標相比較，具有身體形態相對較充實，身體心肺機能水平相對彊的體質特徵。

Objective To explore the physical features of young people of the Li ethnic minority and to pro-vide theoretical basis for the health services of ethnic minority areas. Methods SPSS software was used to establish R clustering matrix model for derived physical indexes in young people of the Li ethnic minority (590 people, includ-ing 290 males and 300 females). The three physical function indexes of young people of the Li ethnic minority were compared with those of 600 youth people of the Han nationality in local place (including 300 males and 300 females). The physical characteristics of young people of the Li ethnic minority were analyzed. Results R type cluster analysis showed that the derived physical indexes of young people of the Li ethnic minority were grouped into two categories, with height/body anteflexion in sitting position, weight (kg)/body anteflexion in sitting position, vital capacity/body weight, vital capacity/step index clustered into one category, and height/standing long jump, weight/standing long jump, weight/height, step test clustered into the other category. Compared with youth people of the Han nationality, the value of weight (kg)/height (cm)×1 000 in young people of the Li ethnic minority were significantly higher, both in males and in females (Pmale<0.01;Pfemale<0.05), while the vital capacity (M1)/weight (kg) showed no statistically signifi-cant difference (P>0.05). Step test index in young people of the Li ethnic minority was significantly higher (Pmale<0.01;Pfemale<0.05). Conclusion In young male people of the Li ethnic minority, the first category of physical indexes re-flect the effect of body height, body weight on body flexion and extension and their potential link with heart and lung function, and the second category of physical indexes reflect the inherent relationship between body weight, body height, weight and length, the level of oxygen uptake and jumping ability. In young female people of the Li ethnic mi-nority, the first category of physical indexes reflect the effect of body weight, body height on body flexion and exten-sion and jumping quality, as well as their potential links with heart and lung function, and the second category of physi-cal indexes reflect the effect of body mass index, body heart and lung function level on the quality of jumping dis-tance. Compared with youth people of the Han nationality, the young people of the Li ethnic minority have relatively better body shape and higher level of heart and lung function.
