多通道用户界面在举重训练数据管理系统中的应用研究 总被引：1，自引：0，他引：1
伴随着计算机信息技术的迅猛发展，计算机辅助训练的各种应用研究正受到越来越多的关注。作为其中的重要部分，训练数据实时管理与测评系统的研究更是备受关注。然而，考虑到训练数据采集的多样性和时空的不确定性，现有基于窗口的单一图形界面的训练数据管理与测评系统给使用者带来了极大不便，难以做到训练数据的实时管理与测评，严重制约了运动训练向科学化发展的步伐。在探讨不同应用环境中的多通道界面和交互方式的基础上，设计开发了多通道交互的举重训练数据管理与测评系统，以达到随时随地对训练数据的实时监管。 相似文献

通过判读手掌和手腕骨的X光成像图片来评价青少年骨龄是体育和医学界一直使用的传统方法,长期的实践应用已证明它是行之有效的。但为变革其固有的缺陷对新的评价方法的探索一直没有停止,其中以色列阳光公司研制的BoneAge超声骨龄检测仪利用定量超声原理来评价骨龄,已批量投入市场且已为国内部分省市的体育部门所采用。研究目的:对BoneAge超声检测方法和传统X光拍摄方法进行方法学比较分析,检验新方法的准确性和有效性,以维护骨龄检测的权威性和科学性。研究对象:5-17岁男女青少年322名。研究方法:(1)超声骨龄仪的可重复性试验(实验对象93名);(2)X光片判读结果与超声检测结果的比较。对223名男女青少年拍摄手掌(腕)骨进行X光拍摄后随即使用BonAge超声骨龄检测仪对同批对象进行手腕部超声扫描。将超声骨龄结果与两位专家对X光片盲式读片结果的平均值进行比较分析。研究结果:(1)对超声骨龄仪的可重复性实验结果表明,两次测试的骨龄均值无显著性差异且呈高度相关,提示该仪器总体稳定性良好;(2)对超声骨龄结果与X光骨龄均值比较的显示,无论是区分年龄段还是性别,两种评定结果之间均有较大的系统误差和随机误差,且这种误差随年龄段的增大而有所加大;对年龄段较高的人群,超声检测结果更易高估对象的骨发育程度;单因变量多因素方差分析表明,骨龄评价结果主要受到评定方法和年龄段因素的影响,而与性别因素关系不大;对超声骨龄和X光骨龄的相关程度和直线回归分析表明,尽管总体人群的两种评价结果存在高度相关,直线回归效果较好,但引入年龄段因素后,相关程度明显降低,回归效果较差,提示这两种方法之间不能相互替代。 相似文献

The purpose of this work was to develop a new 2D gymnast-high bar model with horizontal bar endpoint dynamics included. To
this end, a three-spring high bar model was extended with a five segment gymnast model followed by evaluation and sensitivity
analysis. Evaluation over more than a complete giant swing (420°) was favourable (bar position rms errors <0.017 m, center
of mass angular position rms error <11°). Single parameter perturbations (10%) caused little deterioration in model performance
(lower 180°of the giant swing-bar position rms errors <0.006 m, arms’ angle rms error <0.9°). Combinations of parameter perturbations
gave bar position rms errors <0.008 m and arms’ angle rms error <1.8°. Model performance was most sensitive to errors in high
bar stiffness values. 相似文献

Mechanography during the vertical jump may enhance screening and determining mechanistic causes underlying physical performance changes. Utility of jump mechanography for evaluation is limited by scant test-retest reliability data on force-time variables. This study examined the test-retest reliability of eight jump execution variables assessed from mechanography. Thirty-two women (mean±SD: age 20.8 ± 1.3 yr) and 16 men (age 22.1 ± 1.9 yr) attended a familiarization session and two testing sessions, all one week apart. Participants performed two variations of the squat jump with squat depth self-selected and controlled using a goniometer to 80º knee flexion. Test-retest reliability was quantified as the systematic error (using effect size between jumps), random error (using coefficients of variation), and test-retest correlations (using intra-class correlation coefficients). Overall, jump execution variables demonstrated acceptable reliability, evidenced by small systematic errors (mean±95%CI: 0.2 ± 0.07), moderate random errors (mean±95%CI: 17.8 ± 3.7%), and very strong test-retest correlations (range: 0.73–0.97). Differences in random errors between controlled and self-selected protocols were negligible (mean±95%CI: 1.3 ± 2.3%). Jump execution variables demonstrated acceptable reliability, with no meaningful differences between the controlled and self-selected jump protocols. To simplify testing, a self-selected jump protocol can be used to assess force-time variables with negligible impact on measurement error. 相似文献

Abstract The purpose of this study was to determine the validity and reliability of a new method for measuring three-dimensional (3D) putting stroke kinematics using the TOMI® device. A putting robot and a high-speed camera were used to simultaneously collect data for the validity evaluation. The TOMI® device, when used in conjunction with standard 3D coordinate data processing techniques, was found to be a valid and reliable method for measuring face angle, stroke path, putter speed, and impact spot at the moment of ball contact. The validity of the TOMI® measurement system was quantified using the 95% limits of agreement method for each aforementioned variable. The practical significance of each validity score was assessed by incorporating the maximum estimated measurement error into the stroke of the putting robot for 10 consecutive putts. All putts were executed from a distance of 4 m on a straight and flat synthetic putting surface. Since all putts were holed successfully, the measurement error for each variable was deemed to be negligible for the purposes of measuring putting stroke kinematics. The influence of key kinematic errors, at impact, on the outcome of a putt was also determined. 相似文献

Progress in micro-electromechanical systems has turned inertial sensor units (IUs) into a suitable tool for vertical jumping evaluation. In total, 9 men and 8 women were recruited for this study. Three types of vertical jumping tests were evaluated in order to determine if the data provided by an IU placed at the lumbar spine could reliably assess jumping biomechanics and to examine the validity of the IU compared with force plate platform recordings. Robust correlation levels of the IU-based jumping biomechanical evaluation with respect to the force plate across the entire analysed jumping battery were found. In this sense, significant and extremely large correlations were found when raw data of both IU and force plate-derived normalised force–time curves were compared. Furthermore, significant and mainly moderate correlation levels were also found between both instruments when isolated resultant forces’ peak values of predefined jumping phases of each manoeuvre were analysed. However, Bland and Altman graphical representation demonstrated a systematic error in the distribution of the data points within the mean ±1.96 SD intervals. Using IUs, several biomechanical variables such as the resultant force–time curve patterns of the three different vertical jumps analysed were reliably measured. 相似文献

This study evaluated baseball pitching accuracy using a variety of parameters to quantify pitching errors and analysed the validity of the accuracy measurements by comparing the outcomes of two small groups of pitchers. Several professional (n = 5) and high school (n = 8) pitchers threw 30 pitches each, including 20 fastballs and 10 breaking balls. To assess pitching accuracy, pitch locations relative to the catcher’s mitt (as the target) were evaluated with various parameters, including major/minor radius, an area of 95% confidence ellipse, absolute error, constant error and pitch location trajectory. Compared to the high school pitchers, the professional pitchers exhibited shorter major and minor radii in their 20 fastball pitches (p < 0.05), more accurate control in the lateral direction (p < 0.05), and shorter pitch location trajectories (p < 0.05). The evaluation methods presented in this study can objectively assess pitching accuracy and may thus provide useful coaching feedback with visual information. 相似文献
