Pedometer-determined physical activity and its comparison with the International Physical Activity Questionnaire in a sample of Belgian adults     

De Cocker K  Cardon G  De Bourdeaudhuij I 《Research quarterly for exercise and sport》2007,78(5):429-437

Pedometer-determined physical activity (PA) levels in Belgian adults were provided and compared to PA scores reported in the International Physical Activity Questionnaire (IPAQ). The representative sample (N=1239) of the Belgian population took on average 9655 (4526) steps/day. According to pedometer indices 58.4% were insufficiently active. Steps/day differed significantly between gender (F = 5.0, p = .026), age groups (F = 3.3, p = .01), employment status (F = 6.2, p = .013), and days of monitoring (F = 7.4, p = .007). Steps/day were negatively correlated to the time spent sitting and positively to PA at work, in transport, and in leisure time (p < .001). Steps data can discriminate between PA levels reported in the IPAQ. Belgian population pedometer-determined PA levels are higher than those reported in samples of the United States; however, there is a wide distribution of ambulatory behavior  相似文献   

大学生体育消费行为决定因素的定量分析——以湖北为例   总被引：11，自引：0，他引：11  

段鹏  肖德  赵汉华 《体育科学》2007,27(5):36-40

对学生的体育消费行为进行分类，通过问卷调查的形式，采用统计、计量分析方法，深入分析每类体育消费行为的决定因素及与决定因素之间的定量关系。结果显示，除体育运动的兴趣爱好等主观因素外，学生年生活费用水平、课程压力大小、性别是影响学生体育实物消费的主要客观因素；学生年生活费用水平、性别是影响学生体育信息消费的主要客观因素；学生来源是影响学生体育劳务消费的主要客观因素。这对更深刻地认识体育消费行为、预测高校学生体育消费支出有重要意义。  相似文献

教育是立国之本，强国之路，面对当代科技革命的挑战，党和国家了适时的回应，和出全面推进素质教育的决定。在如何实施素质教育工作中，毛泽东同志关于“教学民主”、“知行统一”、“少而精”、“启发式”等一系列教学思想给我们提供了一定的思路和启迪。  相似文献   

Optimized versus corrected peak power during friction-braked cycle ergometry in males and females     

James DV  Wood DM  Maberly TC  De Ste Croix M 《Journal of sports sciences》2007,25(8):859-867

The aim of this study was to compare optimization and correction procedures for the determination of peak power output during friction-loaded cycle ergometry. Ten male and 10 female sports students each performed five 10-s sprints from a stationary start on a Monark 864 basket-loaded ergometer. Resistive loads of 5.0, 6.5, 8.0, 9.5, and 11.0% body weight were administered in a counterbalanced order, with a recovery period of 10 min between sprints. Peak power was greater and occurred earlier, with less work having been done before the attainment of peak power, when the data were corrected to account for the inertial and frictional characteristics of the ergometer. Corrected peak power was independent of resistive load (P > 0.05), whereas uncorrected peak power varied as a quadratic function of load (P < 0.001). For males and females, optimized peak power (971 +/- 122 and 668 +/- 37 W) was lower (P < 0.01) than either the highest (1074 +/- 111 and 754 +/- 56 W respectively) or the mean (1007 +/- 125 and 701 +/- 45 W respectively) of the five values for corrected peak power. Optimized and mean corrected peak power were highly correlated both in males (r = 0.97, P < 0.001) and females (r = 0.96, P < 0.001). The difference between optimized and mean corrected peak power was 37 +/- 30 W in males and 33 +/- 14 W in females, of which approximately 15 W was due to the correction for frictional losses. We conclude that corrected peak power is independent of resistive load in males and females.  相似文献
