Influence of moderate intensity physical activity levels and gender on conditioned pain modulation     

Masataka Umeda  Wanseok Lee  Courtney A. Marino  Shelby C. Hilliard 《Journal of sports sciences》2016,34(5):467-476

This study examined the potential influence of moderate intensity physical activity (PA) levels and gender on central pain modulation using conditioned pain modulation (CPM) in healthy men and women. Twenty four individuals (12 men and 12 women) who reported engaging in the moderate intensity PA for 150 min or more per week and 24 individuals (12 men and 12 women) who reported engaging in moderate intensity PA for 60 min or less per week completed a self-report PA questionnaire and a 7-day PA assessment using an accelerometer. Furthermore, the participants completed the CPM testing to evaluate the efficiency of central pain modulation. The active individuals scored higher on the PA questionnaire and spent more minutes for light, lifestyle, moderate and vigorous intensity PA than the less active individuals. The active men and women exhibited comparable magnitudes of CPM, and showed a greater magnitude of CPM when compared to their less active counterparts. However, these beneficial effects of higher dose moderate intensity PA disappeared when time spent for vigorous intensity PA was statistically controlled for. These results suggest that the higher dose moderate intensity PA does not add to the benefits from vigorous intensity PA to further improve central pain modulatory systems.  相似文献   

Sex-specific associations of moderate and vigorous physical activity with physical fitness in adolescents

The present study examined the sex-specific associations of moderate and vigorous physical activity (VPA) with physical fitness in 300 Japanese adolescents aged 12–14 years. Participants were asked to wear an accelerometer to evaluate physical activity (PA) levels of various intensities (i.e. moderate PA (MPA), 3–5.9 metabolic equivalents (METs); VPA, ≥6 METs; moderate to vigorous PA (MVPA), ≥3 METs). Eight fitness items were assessed (grip strength, bent-leg sit-up, sit-and-reach, side step, 50?m sprint, standing long jump, handball throw, and distance running) as part of the Japanese standardised fitness test. A fitness composite score was calculated using Japanese fitness norms, and participants were categorised according to their score from category A (most fit) to category E (least fit), with participants in categories D and E defined as having low fitness. It was found that for boys, accumulating more than 80.7?min/day of MVPA may reduce the probability of low fitness (odds ratio (ORs) [95% confidence interval (CI)]?=?0.17 [0.06–0.47], p?=?.001). For girls, accumulating only 8.4?min of VPA could reduce the likelihood of exhibiting low fitness (ORs [95% CI]?=?0.23 [0.05–0.89], p?=?.032). These results reveal that there are sex-specific differences in the relationship between PA and physical fitness in adolescents, suggesting that sex-specific PA recommendation may be needed to improve physical fitness in adolescents.  相似文献   

小学数学课堂练习设计的策略     

王小喜 《宁波教育学院学报》2008,10(1):121-123

在小学数学教学中,练习课约占总教时的一半多,几乎没有一节课是只讲不练的。古人云:"拳不离手,曲不离口"。可见练习的重要性,如何探索新课程理念下的课堂练习设计,是广大教师共同关注的课题。教师可根据教学内容,紧扣教学目标,设计有"坡度"、"难度"、"密度"的练习,加大知识"跨度,"变换练习角度,提高练习设计的有效性。  相似文献   

简述深圳经济发展中的大企业作用     

彭晓峰 《深圳信息职业技术学院学报》2007,5(2):86-89

深圳经济发展到今天的规模,存在的已经不只是GDP总量的问题,而是产业结构调整和可持续发展的问题。与京沪相比,大企业对深圳的贡献作用明显偏低。本文认为,深圳要充分发挥本土大企业的作用,必须通过优质资源向优质企业倾斜,优惠政策向大企业倾斜的政策扶持大企业的发展。本文最后就深圳依托大企业发展物流装备业提出了自己的建议。  相似文献
