Comparison of two Actigraph models for assessing free-living physical activity in Indian adolescents     

Corder K  Brage S  Ramachandran A  Snehalatha C  Wareham N  Ekelund U 《Journal of sports sciences》2007,25(14):1607-1611

This aim of this study was to compare the new Actigraph (GT1M) with the widely used Model 7164. Seven days of free-living physical activity were measured simultaneously using both the Model 7164 and GT1M in 30 Indian adolescents (mean age 15.8 years, s = 0.6). The GT1M was on average 9% lower per epoch than model 7164, thus a correction factor of 0.91 is suggested for comparison between the two monitors. The differences between monitors increased in magnitude with intensity of activity (P < 0.001) but remained randomly distributed (r = 0.01, P = 0.96). No significant difference was observed between monitors for time spent in moderate (P = 0.31) and vigorous (P = 0.34) physical activity when using the same epoch length. The Model 7164 classified less time as sedentary (P < 0.001) and more time as light-intensity activity (P < 0.001) than the GT1M. In conclusion, data from the GT1M can be compared with historical data using average counts per minute with a correction factor, and the two models might be comparable for assessing time spent in moderate to vigorous physical activity in children when using the same epoch length.  相似文献   

Authoritarianism, perceived threat and exclusionism on the eve of the Disengagement: Evidence from Gaza   总被引：1，自引：0，他引：1

Major political events such as terrorist attacks and forced relocation of citizens may have an immediate effect on attitudes towards ethnic minorities associated with these events. The psychological process that leads to political exclusionism of minority groups was examined using a field study among Israeli settlers in Gaza days prior to the Disengagement Plan adopted by the Israeli government on June 6, 2004 and enacted in August 2005. Lending credence to integrated threat theory and to theory on authoritarianism, our analyses show that the positive effect of religiosity on political exclusionism results from the two-staged mediation of authoritarianism and perceived threat. We conclude that religiosity fosters authoritarianism, which in turn tends to move people towards exclusionism both directly and through the mediation of perceived threat.  相似文献   

Effects of rest interval during high-repetition resistance training on strength, aerobic fitness, and repeated-sprint ability   总被引：1，自引：0，他引：1  

Hill-Haas S  Bishop D  Dawson B  Goodman C  Edge J 《Journal of sports sciences》2007,25(6):619-628

The effect of altering the rest period on adaptations to high-repetition resistance training is not well known. Eighteen active females were matched according to leg strength and repeated-sprint ability and randomly allocated to one of two groups. One group performed resistance training with 20-s rest intervals between sets, while the other group employed 80-s rest intervals between sets. Both groups performed the same total training volume and load. Each group trained 3 days a week for 5 weeks [15- to 20-repetition maximum (RM), 2 - 5 sets]. Repeated-sprint ability (5x6-s maximal cycle sprints), 3-RM leg press strength, and anthropometry were determined before and after each training programme. There was a greater improvement in repeated-sprint ability after training with 20-s rest intervals (12.5%) than after training with 80-s rest intervals (5.4%) (P = 0.030). In contrast, there were greater improvements in strength after training with 80-s rest intervals (45.9%) than after training with 20-s rest intervals (19.6%) (P = 0.010). There were no changes in anthropometry for either group following training. These results suggest that when training volume and load are matched, despite a smaller increase in strength, 5 weeks of training with short rest periods results in greater improvements in repeated-sprint ability than the same training with long rest periods.  相似文献

斯坦福大学陆上训练计划     

S·舒尔策  S·罗迪欧  徐乐 《中国体育科技》1985,(Z1)

在斯坦福大学,力量训练设施在游泳训练总体发展中起着重要的作用,游泳运动员每周训练很多时间,严格的陆上训练从每天早上的六时开始,女子游泳队教练员乔治·海恩斯和男子游泳队教练阿伦·肯尼认为力量训练是游泳队成功的关键一环。游泳队有一名工作人员负责设计陆上训练计划,首先由他提出设计方案。助理力量教练员斯科特·罗迪欧(从前是斯坦福大学的游泳运动员)(译注:本文作者之一)在探讨游泳队的全部需要和训练目标上密切与游泳教练员合作,然后设计了这个计划,使之精炼并修订它,最后将它送交游泳教练员,得到他们最后批准。安排一个时间,召集男、女游泳队,向他  相似文献
