目的描述西双版纳州1985—2010年25 a来7~18岁傣族学生身体形态、生理功能和身体素质的变化特点,为研究傣族学生生长发育提供科学依据。方法利用1985年、1990年、2000年、2010年全国学生体质健康调研数据中云南省资料,对7~18岁傣族学生体质健康状况进行比较分析。结果 1985—2010年,7~18岁傣族学生形态指标有不同程度的增长,男、女身高分别增长3.94,2.99 cm,体重分别增长2.69,2.06 kg,胸围分别增长2.63,3.14 cm。各年龄组肺活量呈明显下降趋势,男、女肺活量分别下降304.55,237.14 mL。速度素质男生基本持平、女生下降,力量素质均明显提高,耐力素质明显下降,柔韧性降低;女生除柔韧性优于男生,其余项目男生均优于女生。结论 7~18岁傣族学生生理功能和耐力素质指标明显下降。应针对学生生理功能和部分身体素质指标下降的特点,采取干预措施,增强学生体质。
Objective To describe the changes of body shape, physiological functions and physical fitness of Dai students aged 7-18 years from 1985 to 2010 in Xishuangbanna Prefecture, and to provide scientific basis for studying the growth and development of Dai students. Methods By using the data of Yunnan Province from the survey data of 1985-2009, 2000, 2010 and 2010, the health status of Dai students aged 7-18 was compared and analyzed. Results From 1985 to 2010, the morphological indices of Dai students aged 7-18 years increased to some extent. The height of male and female students increased by 3.94 and 2.99 cm respectively, the body weight increased by 2.69 and 2.06 kg respectively, and the busts increased by 2.63 and 3.14 cm respectively. The vital capacity of all age groups showed a significant downward trend, male and female lung capacity decreased 304.55,237.14 mL. Speed boys were basically the same quality, girls decreased, strength and quality were significantly improved, endurance quality decreased significantly, flexibility decreased; girls than the flexibility than boys, the rest of the boys were better than girls.
