通过建立乒乓球的动力数学模型,对弧圈球在每一种情况下的运动规律及运行轨迹变化曲线进行分析。结果显示:影响弧圈球运行轨迹的主要因素有乒乓球运动方向、运动速度、旋转速率、加速度及Magnus力,其中乒乓球运动方向和Magnus力的变化是改变乒乓球速度变化的重要因素;在运行过程中,球向的不断变化使弧圈球的速度及加速度也不断改变;而影响乒乓球运行轨迹的直接因素是旋转速率,且弧圈球第一弧线和第二弧线在不同旋转速率下存在着明显的区别。 相似文献

AbstractThe capturing of movements by means of wearable sensors has become increasingly popular in order to obtain sport performance measures during training or competition. The purpose of the current study was to investigate the feasibility of using body worn accelerometers to identify previous highlighted performance related biomechanical changes in terms of substantial differences across skill levels and skating phases. Twenty-two ice hockey players of different caliber were equipped with two 3D accelerometers, located on the skate and the waist, as they performed 30 m forward skating sprints on an ice rink. Two measures of the temporal stride characteristics (contact time and stride time) and one measure of the propulsive power (stride propulsion) of a skating stride were calculated and checked for discriminating effects across (i) skill levels and (ii) sprint phases as well as for their (iii) strength of association with the sprint performance (total sprint time). High caliber players showed an increased stride propulsion (+22%, P?<?0.05) and shorter contact time (?5%, P?<?0.05). All three analysed variables highlighted substantial biomechanical differences between the accelerative and constant velocity phases (P?<?0.05). Stride propulsion of acceleration strides primarily correlated to total sprint time (r?=??0.57, P?<?0.05). The results demonstrate the potential of accelerometers to assess skating technique elements such as contact time or elements characterizing the propulsive power such as center of mass acceleration, to gauge skating performance. Thus, the findings of this study might contribute to establishing wearable sensors for in-field ice hockey skating performance analysis. 相似文献

Abstract This study verified earlier anecdotal evidence indicating that spatial assimilations could be reduced by offsetting movements in time. In Experiment 1, 40 right-handed participants (ages 18–23 years) made single and dual quick lever reversals of 20° and 60° with the left and right limbs, respectively. Participants were assigned to either the Overlapping (O) group, in which one limb began when the other limb reached the reversal point, or to the Sequential (S) group in which one limb followed the other with a delay of 114 ms, on average. The shorter-distance limb of the O group overshot relative to the S group. Short-distance spatial assimilations were also shown in the S group in Experiment 2, when the delay was increased to 250, 500, or 1,500 ms (N = 30), suggesting that assimilation effects can be caused by command interactions at both the planning and the execution levels. 相似文献

In this study, life satisfaction and its correlates were explored through analysis of the experiences and psychological traits of highly gifted students who were accelerated into an early college-entrance program. Happiness, fulfillment in life, assuredness, and good dispositions are constructs that point toward positive character development and thriving. These early college entrants expressed greater global satisfaction with their lives than age peers. They specifically reported elevated levels of satisfaction in their achievements, immediate standard of living, personal safety, and future security than age peers. They expressed powerful feelings of general self-efficacy and high levels of trait seriousness, two constructs related to facilitating success. The findings in this study suggest these early college entrants are on a path toward personal thriving and living a good life. 相似文献
