赛艇运动中频率、浸水深度和幅度之间的关系 总被引：2，自引：0，他引：2
研究通过对赛艇“Blig Blade”桨叶的流体动力性能的数值模拟和试验研究以及理论分析，讨论了不同的划桨频率、浸水深度和划桨幅度等运动学参数和动力学参数对桨叶流体动力性能的影响，研究结果和结论：（1）桨叶与水之间的相对运动是桨叶产生作用力的根本原因；（2）随着桨叶浸水深度的增加，桨叶产生的作用力也在增加；（3）大的划桨幅度推进效率是比较低的。建议：划船器材的调整和划船技术都应围绕提高水下的拉桨速度来进行，提高拉桨频率不能够以牺牲桨叶的浸水深度为代价，更不能以牺牲频率来服朋幅度。 相似文献

论新生活运动正当娱乐中的体育 总被引：1，自引：0，他引：1
新生活运动历时15年,涉及到了国民生活的方方面面。娱乐作为生活的重要组成部分,也受到新生活运动的影响。为了纠正社会上根深蒂固的“烟”、“赌”和“娼”等不良风气,新生活运动组织十分重视对正当娱乐的提倡,对体育尤为重视。蒋介石本人在新生活运动周年纪念大会上专门提到过体育问题。体育活动曾被作为新生活运动的年度中心工作或者工作要点来开展。虽然最后对体育的提倡没有达到十分理想的效果,但确实引导了国民的健康观念。新生活运动组织还培养了数量不多的体育人员,为近代体育的发展注入了动力。 相似文献

AbstractThe aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r2 = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r2 = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r2 = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance. 相似文献

A physiotherapist is part of the multidisciplinary team in most intensive care units in Australia. Physiotherapists are primary contact practitioners and use a comprehensive multisystem assessment that includes the respiratory, cardiovascular, neurological, and musculoskeletal systems to formulate individualized treatment plans. The traditional focus of treatment has been the respiratory management of both intubated and spontaneously breathing patients. However, the emerging evidence of the longstanding physical impairment suffered by survivors of intensive care has resulted in physiotherapists re-evaluating treatment priorities to include exercise rehabilitation as a part of standard clinical practice. The goals of respiratory physiotherapy management are to promote secretion clearance, maintain or recruit lung volume, optimize oxygenation, and prevent respiratory complications in both the intubated and spontaneously breathing patient. In the intubated patient, physiotherapists commonly employ manual and ventilator hyperinflation and positioning as treatment techniques whilst in the spontaneously breathing patients there is an emphasis on mobilization. Physiotherapists predominantly use functional activities for the rehabilitation of the critically ill patient in intensive care. While variability exists between states and centers, Australian physiotherapists actively treat critically ill patients targeting interventions based upon research evidence and individualized assessment. A trend toward more emphasis on exercise rehabilitation over respiratory management is evident.Key Words: physiotherapy, intensive care 相似文献

AbstractLateral movements like cutting are essential in many team sport disciplines. The aim of the present study was to analyse adaptations in motor control in response to task unpredictability during lateral movement execution. Twelve subjects performed lateral jumps with different landing modalities (stable, sliding or counteracting) that were either known (predictable setting) or unknown (unpredictable setting) prior to movement execution. Results revealed that regardless of the landing modality, hip joint abduction was significantly greater in the unpredictable compared to predictable setting. Furthermore, during the sliding landing modality, hip flexion decreased from 211 ± 7° to 207 ± 7° and knee flexion decreased from 26 ± 4° to 24 ± 4° at the instant of ground contact in the unpredictable compared to predictable condition. During the stable landing modality, the knee joint abduction increased from ?0.3 ± 6° to ?3 ± 6° after initial ground contact in the unpredictable compared to predictable setting. The present results support our hypothesis that pre-programmed motor activity depends on the predictability of the landing modality during lateral movements. According to its adaptation in the frontal plane and in some extent in the sagittal plane, the hip joint seems to play the major role in the modulation of the pre-programmed activity for successful lateral jump execution in an unpredictable setting. However, these kinematic adaptations are concerning since these changes were associated with higher knee abduction during the stable landing modality and therefore with possible higher risk of injury. 相似文献
