目的通过逐级递增负荷运动试验测定13~15岁中学生最大有氧活动能力,建立间接预测模型。方法选取武汉市区一所初中31名学生作为研究对象,利用活动跑台对研究者的最大摄氧量进行测量,同时测量身高、体重、肺活量(VC)、脂肪体重和安静心率... 目的通过逐级递增负荷运动试验测定13~15岁中学生最大有氧活动能力,建立间接预测模型。方法选取武汉市区一所初中31名学生作为研究对象,利用活动跑台对研究者的最大摄氧量进行测量,同时测量身高、体重、肺活量(VC)、脂肪体重和安静心率,计算体质指数和体脂百分比,分析最大摄氧量与人体测量学指标的相关性,并建立多元线性回归预测模型。结果男生的相对最大摄氧量[(48.00±5.80)L/min vs(39.79±6.37)L/min,t=3.753,P<0.001]、绝对最大摄氧量[(2.66±0.29)m L/(kg·min)vs(2.02±0.36)m L/(kg·min),t=5.418,P<0.001]及氧脉搏[(13.33±1.28)m L/次vs(10.34±1.70)m L/次,t=5.562,P<0.001]均高于女生,且差异具有统计学意义;最大摄氧量与体重、BMI、体脂百分比及安静心率呈负相关(P<0.05),与瘦体重呈正相关(P<0.05);采用多元线性回归建立男生VO_(2max)预测模型为:VO_(2max)=0.856+0.044×瘦体重-0.011×安静心率+0.0002×肺活量,其中R=0.903,R^2=0.816;女生预测方程为VO_(2max)=4.769+0.044×瘦体重-0.020×安静心率-0.254×年龄,R=0.813,R^2=0.662。结论人体测量学指标与最大摄氧量密切相关,可有效预测有氧活动能力。 展开更多

The risk factors of high trait anger of juvenile offenders were explored through questionnaire study in a youth correctional facility of Hubei province, China. A total of 1090 juvenile offenders in Hubei province were investigated by self-compiled social-demographic questionnaire, Childhood Trauma Questionnaire(CTQ), and State-Trait Anger Expression Inventory-Ⅱ(STAXI-Ⅱ). The risk factors were analyzed by chi-square tests, correlation analysis, and binary logistic regression analysis with SPSS 19.0. A total of 1082 copies of valid questionnaires were collected. High trait anger group(n=316) was defined as those who scored in the upper 27 th percentile of STAXI-Ⅱ trait anger scale(TAS), and the rest were defined as low trait anger group(n=766). The risk factors associated with high level of trait anger included: childhood emotional abuse, childhood sexual abuse, step family, frequent drug abuse, and frequent internet using(P〈0.05 or P〈0.01). Birth sequence, number of sibling, ranking in the family, identity of the main care-taker, the education level of care-taker, educational style of care-taker, family income, relationship between parents, social atmosphere of local area, frequent drinking, and frequent smoking did not predict to high level of trait anger(P〉0.05). It was suggested that traumatic experience in childhood and unhealthy life style may significantly increase the level of trait anger in adulthood. The risk factors of high trait anger and their effects should be taken into consideration seriously. 展开更多
