The aim of this study was to investigate the throwing velocity and kinematics of overarm throwing in team handball of elite female and male handball players. Kinematics and ball velocity of a 7 metre-throw in eleven elite male (age 23.6 ± 5.2 yr, body mass 87.0 ± 6.8 kg, height 1.85 ± 0.05 m) and eleven elite female (age 20.3 ± 1.8 yr, body mass 69.9 ± 5.5 kg, height 1.75 ± 0.05 m) team handball players were recorded. The analysis consisted of maximal joint angles, angles at ball release, maximal angular velocities of the joint movements, and maximal linear velocities of the distal endpoints of segments and their timing during the throw. The ball release velocity of the male handball players was significantly higher than the females (21.1 vs. 19.2 m · s(-1); p < 0.05). No major differences in kinematics were found, except for the maximal endpoint velocities of the hand and wrist segment, indicating that male and female handball players throw with the same technique. It was concluded that differences in throwing velocity in elite male and female handball players are generally not the result of changes in kinematics in the joint movements. 相似文献

This study investigated ball release speed and performance kinematics between elite male and female cricket fast bowlers. Fifty-five kinematic parameters were collected for 20 male and 20 female elite fast bowlers. Group means were analysed statistically using an independent samples approach to identify differences. Significant differences were found between: ball release speed; run-up speed; the kinematics at back foot contact (BFC), front foot contact (FFC), and ball release (BR); and the timings between these key instants. These results indicate that the female bowlers generated less whole body linear momentum during the run-up than the males. The male bowlers also utilised a technique between BFC and FFC which more efficiently maintained linear momentum compared to the females. As a consequence of this difference in linear momentum at FFC, the females typically adopted a technique more akin to throwing where ball release speed was contributed to by both the whole body angular momentum and the large rotator muscles used to rotate the pelvis and torso segments about the longitudinal axis. This knowledge is likely to be useful in the coaching of female fast bowlers although future studies are required to understand the effects of anthropometric and strength constraints on fast bowling performance. 相似文献

运用文献资料法、数理统计法、逻辑分析法,对2004-2012年间参加奥运会、世锦赛男女跳高、跳远、三级跳、撑杆跳八个单项的前三名共126名运动员的竞赛成绩及其年龄特征进行统计并对其相关性进行分析,初步探讨形成这一特征的因素,为田径体能跳跃类项目的选材与训练提供参考。研究结果显示:在这四个项目中,跳远男女运动员的年龄与竞赛成绩成正相关;三级跳和撑杆跳男女运动员的年龄与竞赛成绩成负相关;跳高项目男子运动员竞赛成绩与年龄成正相关,女子运动员成负相关。因此,运动训练中应有针对性地根据不同项目、不同性别,合理地进行运动员选材、安排训练计划与人才培养,进行符合运动员自身年龄阶段特征的训练,不断挖掘其运动潜质,提高运动员竞技成绩。 相似文献

通过论述评价撑杆跳高“自由起跳”技术的指标,从而使得撑杆跳高“自由起跳”技术的评价,有一个统一的指标评价体系,为客观评价优秀撑杆跳高运动员起跳技术提供统一的指标。为更多研究撑杆跳高技术的学者提供统一的评价和交流平台。撑杆跳高“自由起跳”技术,是运动员在起跳过程中,有一个短暂脱离撑杆约束的运动瞬间,技术动作要求运动员的踏跳点严格地控制在静态插穴时,上手握点的投影上。由此论述产生几项评价指标,如最后两步助跑至起跳完成这一过程的速度情况、起跳角度、上握手的投影点距起跳点距离、起跳及插穴时间、起跳时杆弦角以及起跳时杆弦的缩短量等。 相似文献

Discriminant analysis of anthropometric and biomotor variables among elite adolescent female athletes in four sports 总被引：1，自引：1，他引：0
The aim of this study was to identify anthropometric and biomotor variables that discriminated among groups of elite adolescent female athletes aged 14.3 +/- 1.3 years (mean +/- s) from four different sports (tennis, n = 15; swimming, n = 23; figure skating, n = 46; volleyball, n = 16). The anthropometric variables included body mass, height, bi-epicondylar breadth of the distal extremity of the humerus and femur, maximal girth of the calf and biceps and the sum of five adipose skinfolds. The biomotor variables were maximal aerobic power, muscular endurance and flexibility of the trunk. Discriminant analysis revealed three significant functions (P < 0. 05). The first discriminant function primarily represented differences between figure skaters and all other groups of athletes. The other two underlined anthropometric and biomotor differences between swimmers and volleyball players and between tennis players and swimmers, respectively. After validation, the analysis showed that 88% of the athletes were correctly classified in their respective sports. Our model confirms that elite adolescent female athletes show physical and biomotor differences that clearly distinguish them according to their particular sport. 相似文献

The aims of this study were to gain insights on sepaktakraw serves, identify technique differences, and establish factors influencing ball speeds. The best successful kuda and sila serves of nine elite male national sepaktakraw players were captured using seven ProReflex 1000 optical cameras operating at 240 Hz. The kuda and sila serves are non-planar kicking techniques exhibiting a non proximal-to-distal sequence. Differences in kicking kinematics (P < 0.05) signify differences between techniques. Compared with the sila, the kuda kicking limb is a longer rigid segment that moves over a greater range of motion. Together with a greater increase in foot and shank angular accelerations approaching ball contact, this leads to marginally higher kuda foot impact speeds. Since foot speeds were not at their peak during impact, a longer rigid kuda kicking limb was the primary determinant of kuda ball release speeds. Greater range of motion enables the longer rigid kuda lever to generate greater kicking angular momentum, resulting in greater impact impulse. This immediately translated to the significantly higher ball release speeds based on the impulse-momentum relationship. Coaching implications include improving hip joint flexibility and working on a fluid movement of a longer rigid segment kicking technique. 相似文献
