人体皮纹学早已在医学、司法部门得到应用,近十多年来,在体育界开始研究和应用,其应用依据是根据皮纹具有遗传性、个体差异性和终身不变性等特点。由于皮纹取样简便易行,对人体无害,易于推广。在体育界,以往主要是对不同运动项目运动员的皮纹特征进行研究,而对皮纹与人体潜能之间关系的研究,未见报道。本研究对人体皮纹的表现特征与体能等方面有何内在联系进行探讨,以寻求对运动员选材建立一个新的指标参考。1研究对象对227名少年队员测试（神经类型测试表,并肤纹测试,男144人,女83人）,另对50名男女青年运动员测试了心脏功能… 相似文献

本文报道了我国优秀皮划艇运动员的手纹特征及其综合评价成绩。研究结果进一步证明皮划艇运动员手纹特征与运动技术水平之间有一定的相关性;并观察到,皮划艇运动员手指端白线和斗型纹总数出现率均较高,尤其是拇指端白线和斗型纹(特别是双箕斗型纹)出现率均较高的现象;联系到拇指在人体劳动和运动中抓握功能及地位,提示,这种特征可能与握桨或抓握动作有关。 相似文献

A postural tremor appears whenever someone attempts to maintain a steady position against gravity. We examined the postural tremor that occurred while air pistol shooters were taking aim so as to compare the coordinative control of the shooters and to identify the features critical to successful shooting. Ten elite and ten pre-elite athletes participated in pistol shooting at 10 m, and the postural tremors in the pistol and upper limb were recorded with lightweight accelerometers. Exploratory analysis showed that the elite shooters had smaller tremor amplitudes than the pre-elite shooters in the pistol and distal arm segments. Compared with the pre-elite shooters, the elite shooters had a smaller tremor amplitude in the lateral direction relative to that in the vertical direction, together with weaker tremor coupling in the lateral direction and stronger vertical coupling of the pistol-hand complex. The resulting shot performance was inversely related to the amplitude of the tremor and to the 8-12 Hz spectral peak of the lateral tremor in the pistol-hand complex. We conclude that the postural tremors of air pistol shooters are associated with the skill of the shooters, and that the elite shooters could optimize the control of the pistol-hand complex, which strongly determined success in shooting. 相似文献

了解不同水平射击运动员的脑电α波特点，为射击运动员的科学选材和训练控制提供一定的参考依据。方法：采用高级运动训练状态监控仪采集、分析了19名国家射击队运动员和19名广东省射击运动员不同训练阶段的152个样本的脑电α波信号。结果：不同水平射击运动员的脑α波类型无显著性差异，但高水平运动员表现出了较高的协同趋势和稳定度；不同水平运动员的熵值及脑α波各类型主频熵值均无显著性差异，但奥运冠军与国家队、广东省队协同稳定度高的被试的熵值存在显著性差异。 国家队认知型和优化型运动员的脑电α波主频与熵值呈显著性负相关。结论：不同水平射击队员的脑电α类型仿向认知型，认识型可作为射击运动员选材的参考指标；高水平射击运动员的训练适应状态和竞技水平的稳定程度均优于低水平运动员；熵值可作为监控优秀射击运动员训练适应状态的参考指标。 相似文献

Visual behaviour of pistol shooters of various levels of experience was studied using a video-oculometric technique to record the direction of gaze. A spatio-temporal analysis of the fixation patterns of subjects (five international pistol shooters and five international pentathletes) found that patterns were related to the level of skill. The pentathletes, whose level was lower, positioned their gaze on the weapon sight and visually followed the movement of the weapon towards the target. The pistol shooters appeared to use negative feedback in bringing up their weapons, so reducing the angle formed by the weapon, target and gaze. They fixed their gaze directly on the target or between the target and the weapon. Observations showed a prolonged time of attack (means = 1.107 s vs 0.558 s; P less than 0.001) and a shorter stabilization time (means = 0.714 s vs 1.216 s; P less than 0.001) for the most expert shooters. The psycho-physiological mechanisms which were the basis of these patterns and the reasons why shooters chose them are discussed. 相似文献
