双箕斗是运动员皮纹选材中的重要指标之一,在对原630名体操运动员中有双箕斗的260人的皮纹样本进行重新观察、并按运动成绩分组进行分析后发现：（1）世界级体操运动员在双箕斗的判定上无任何误判,两个箕头均较完整,不易与近似的叶形斗相混。（2）优秀体操运动员的双箕斗,左指上右箕头朝下,右指上左箕斗朝下,我们称之为反向双箕,出现率比一般运动员明显增高。（3）优秀体操运动员,特别是男子,他们在双箕斗的形状分类中,中心点到下箕头第一条弧形线的距离长度＞6mm的长双箕的出现率明显高于一般运动员。（4）优秀体操运动员中,嵴线数＞20条的特大型双箕明显少于一般运动员。（5）优秀体操运动员的双箕斗,其两个箕中心到本侧三叉这两点间的距离比与一般运动员相比明显小,对称性较好。因此在运动员皮纹选材时,双箕斗的观察可提供了一定的借鉴和参考作用。 相似文献

优秀少年体操运动员的气质类型与选材 总被引：4，自引：0，他引：4
对上海市４８名优秀少年体操运动员（８～１４岁）进行了问卷测试，发现其气质类型的分布趋势为：粘液质兼型人数最多（３６人），多血质兼型其次（２９人），纯单一气质类型的人数甚少。从理论分析及众多教练员的经验都说明，这两种气质类型与体操运动的内在要求有着密切的联系，因而认为可以将其作为体操运动员选材条件之一。 相似文献

据国内外文献记载,大多数运动员的心脏比一般人增大,其增大的数值随运动项目的不同而不同。我国学者在自行车、马拉松、田径、体操、举重、兰球、游泳、排球、足球、网球等运动项目方面曾作过一些研究,但在划船运动项目方面尚未见报道。为了探讨我国划船运动员的心脏特点,给教学、训练及选材提供一些参考数据,本文对77名优秀划船运动员作了心脏X线摄形态片、测量与分析,现报告如下: 相似文献

The aim of the study was to determine if sex differences exist in the key elbow and wrist joint injury risk factors during different cartwheel (CW) and round-off (RO) techniques performed by young male and female artistic gymnasts. Sixteen active young gymnasts (8 males and 8 females) performed 30 successful trials of CW and RO with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic and kinetic data were collected for each trial. Two-way repeated measures ANOVA (3 × 2, technique × sex) and effect-sizes (ES) were used for statistical analysis. In conclusion, female gymnasts exhibited greater normalised peak vertical ground reaction forces (VGRF), elbow and wrist compression forces and elbow internal adduction moments during CW and RO skills compared with male gymnasts. In both sexes, the parallel and reverse techniques increased peak VGRF, elbow and wrist compression forces and the elbow internal adduction moment. Increased elbow flexion resulted in decreased peak VGRF, elbow compression forces and elbow internal adduction moment. Injury risk factors including elbow extension and internal adduction moment with axial compression force suggest that a CW and RO in reverse and parallel techniques can be hazardous especially for young female gymnasts. 相似文献

The aim of this study was to examine the biomechanical injury risk factors at the wrist, including joint kinetics, kinematics and stiffness in the first and second contact limb for parallel and T-shape round-off (RO) techniques. Seven international-level female gymnasts performed 10 trials of the RO to back handspring with parallel and T-shape hand positions. Synchronised kinematic (3D motion analysis system; 247 Hz) and kinetic (two force plates; 1235 Hz) data were collected for each trial. A two-way repeated measure analysis of variance (ANOVA) assessed differences in the kinematic and kinetic parameters between the techniques for each contact limb. The main findings highlighted that in both the RO techniques, the second contact limb wrist joint is exposed to higher mechanical loads than the first contact limb demonstrated by increased axial compression force and loading rate. In the parallel technique, the second contact limb wrist joint is exposed to higher axial compression load. Differences between wrist joint kinetics highlight that the T-shape technique may potentially lead to reducing these bio-physical loads and consequently protect the second contact limb wrist joint from overload and biological failure. Highlighting the biomechanical risk factors facilitates the process of technique selection making more objective and safe. 相似文献

Biophysical loading of the elbow and wrist is a potential reason for chronic lesions in gymnastics and present a real concern for coaches, scientist and clinicians. Previous research has identified injury risk factors during round-off (RO) skills in elite female gymnasts. The aim of this study was to investigate key elbow and wrist joint injury risk factors during different techniques of fundamental cartwheel (CW) and RO skills performed by young female artistic gymnasts. Seventeen active young female gymnasts performed 30 successful trials of both CW and RO from a hurdle step with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic (240?Hz) and kinetic (1200?Hz) data were collected for each trial. One-way repeated measures ANOVA and effect size (ES) were used for statistical analysis. The results showed statistically significant differences (P?0.8) among hand positions for peak vertical ground reaction force (VGRF), peak elbow compression force, peak wrist compression force, elbow internal adduction moment and wrist dorsiflexion angle. In conclusion, the parallel and reverse techniques increase peak VGRF, elbow and wrist compression forces, and elbow internal adduction moment. These differences indicate that the parallel and reverse techniques may increase the potential of elbow and wrist injuries in young gymnasts compared with the T-shape technique; this is of particular importance with the high frequency of the performance of these fundamental skills. 相似文献

The aim of this study was to determine the range of movement in gymnastic and dance populations. Sixty-five participants (41 females, 24 males; mean age 21.4 years) were assessed. The sample included dancers and gymnasts ranging from novice and club standard to international and professional status. Non-specialized physical education students acted as controls. Range of movement was measured at the shoulders, hips, lumbar spine and ankles using a Loebl hydrogoniometer, and inherent joint laxity was assessed using Beighton and coworkers' adaptation of the Carter and Wilkinson 9-point scale. The right and left sides of the body were assessed and measures of active and passive motion were recorded. A graded increase in laxity was observed from controls, through novice gymnasts, to dancers and finally international gymnasts. The greater laxity of females than males was also confirmed. Dancers and gymnasts had a greater passive range of movement in all joints, which was partly inherited and partly acquired. There was a large difference between their active and passive ranges, which appeared to render the joints unstable. 相似文献
