坐式排球是残疾人奥运会正式比赛项目,2000年我国把坐式排球列为全国残疾人运动会正式比赛项目。经过五年的发展,我国坐式排球运动水平已进入世界六强行列。为了完成2008年北京残奥会上男女双获金牌的战略目标,当前最重要的工作就是加强二线队伍的建设,加大运动员的选材力度。经过三年的跟队研究,总结出坐式排球运动员选材的特殊性:放宽运动员的年龄界限,要求队员有较长的上体和上肢。残障程度:以小腿截肢和两下肢不等长的运动员最适合参加坐式排球运动的训练。在挑选攻手时,注意残障腿与扣球手成反向;在挑选二传手时,残障腿是右腿的运动员更适合。 相似文献

This study examined the accuracy of self-attachment of the activPAL activity monitor. A convenience sample of 50 participants self-attached the monitor after being presented with written material only (WMO) and then written and video (WV) instructions; and completed a questionnaire regarding the acceptability of the instructional methods. Participants positioned the monitor lower than the instructed position on the thigh (WMO ?5.15 ± 2.75 cm, WV ?4.16 ± 2.15 cm; p = .008 difference) and approximately 2 cm laterally from the thigh midline (WMO 1.90 ± 0.92 cm; WV 2.08 ± 1.24 cm). The orientation of the device was positioned correctly along the midline (within < 1° of vertical). Acceptability was high for both instructional methods although preference was shown for the WV instruction. In conclusion, participants consistently self-attached the activPAL close to the intended placement with either instructional method. The addition of video instruction produced a slightly more accurate attachment and was preferred by the participants. 相似文献

坐卧类家具是人们日常生活中常见的与人体接触最密切的家具,起着支撑人体、缓解疲劳、供人休息的作用。但是,坐卧类家具在功能尺度设计上仍存在许多缺陷。坐卧类家具功能尺寸设计必须依据人体测量学提供的参数为依据,把人体工程学的要素与其它要素综合起来,依照“以人为本”的设计理念,才能设计出符合人们使用的坐卧类家具,体现家具设计的人性化。 相似文献

The aim of this study was to examine relationships between activPAL?-determined sedentary behavior (SB) and physical activity (PA) with academic achievement. A total of 120 undergraduates (N = 57 female; 20.6 ± 2.3 years) participated in the study. Academic achievement was measured as the grade point average obtained from all completed courses. Participants wore on the right tight an activPAL? for 7 days to determine total sedentary time, total number of sedentary breaks, sedentary bouts, standing time, light and moderate-to-vigorous physical activity (MVPA). Separate multiple linear regression models were performed to examine associations between SB variables and academic achievement. Light PA, MVPA, total sedentary time, total standing time, or total number of sedentary breaks were not related to academic achievement. Independently of PA, the amount of time spent in sedentary bouts of 10-20min during weekdays was positively related to academic achievement. Given that college students spend the majority of their workday in environments that encourage prolonged sitting, these data suggest that interruptions in prolonged periods of sitting time every 10-20min via short breaks may optimize cognitive operations associated with academic performance. 相似文献
