从肌肉力学的观点出发,通过对三级跳远运动员不同高度跌深及三级跳远跨步跳踏跳的测试,分析了受试者下肢肌的“承受能力”。研究表明:最适宜高度跳深承受载荷与三级跳远成绩呈正相关,相关程度紧密;受试者三级跳远跨步跳踏跳承受的垂直载荷远大于他们最适宜高度跳深时承受的载荷,他们下肢肌“承受能力”较差,致使跨步跳蹬伸无力,未产生良好的起路效果。  相似文献

一、助跑(尤其是后三步)、攻板的速度、节奏与踏跳的训练是影响三级跳远技术第一因素 大家都知道,三级跳远技术是由助跑起跳、单脚跳、跨步跳与跳跃几个环节构成。助跑起跳作为整个技术的第一环节,它决定着后面技术的发挥或者说直接影响着该次试跳的有效性。因此加强助跑起跳训练尤其是助跑后三步的速度训练与踏跳蹬伸起跳训练是创造优异成绩的第一步。  相似文献

跳远和三级跳远均属于典型的速度力量型远度项目。采用文献资料、专家访谈、测试法和数理统计等研究方法,通过对我国优秀男子跳远和三级跳远运动员的助跑最后一步的某些运动学参数进行对比研究,结果表明:(1)助跑最后一步摆动腿支撑阶段的身体重心高度变化值,跳远组比三级跳远组大且具有显著性差异。(2)助跑最后一步的最大缓冲瞬间,跳远组的摆动腿大腿角速度比三级跳远组大,且具有显著性差异。(3)助跑最后一步支撑阶段摆动腿缓冲扇角和蹬伸扇角,三级跳远组均大于跳远组。  相似文献

助跑速度与跳远成绩之间存在高度的相关 ,是影响跳远成绩的主要因素。在当今世界跳远助跑速度越来越快且助跑速度日趋接近的今天 ,踏跳技术的差异已成为决定成绩优劣的一个重要指标。因此 ,跳远成绩不仅取决于助跑速度 ,而且在较大程度上受到踏跳技术和踏跳能力的制约。  相似文献

纵跳摸高能力是优秀篮球运动员比赛争抢板球和原地起跳投篮的重要专项素质之一,纵向摸高素质的提高与多种跳跃素质(如助跑摸高、五级蛙跳、连续快速起跳等)可能具有密切的相关关系(假说)。男子篮球运动员纵向摸高素质与跳跃素质的相关关系和科学训练的研究是很有必要的。文章以山西省体育职业学院20名男子篮球专项学生为研究对象,运用测试法测出:原地纵跳摸高、助跑摸高、立定跳远、30秒单摇跳绳、五级蛙跳、立定三级跳各项数据并得出相应的研究结果,以期为相关研究提供参考。  相似文献

运用文献资料法、运动学及动力学测试法,对跳深跳远离台动作对落地动作的影响做了生物力学的分析。研究显示:跳深跳远第二高度第三坡度落地有最小的水平制动力和最大的垂直支撑反作用力,适宜进行落地积极缓冲和落地瞬间的退让性工作能力的训练;第一跳起跳的起跳角与第一跳落地水平制动力成负相关,可以通过增大起跳角来减小水平制动力;垂直速度、腾起角与第一跳落地垂直支撑反作用力呈高度显著性负相关,根据训练目的适当增大或减小第一跳起跳的垂直速度和腾起角可以获得相应的落地乖盲支撑反作用力。  相似文献

In this study, we compared the kinematic variables of the split triple twist with those of the split double twist to help coaches and scientists understand these landmark pair skating skills. High-speed video was taken during the pair short and free programmes at the 2002 Salt Lake City Winter Olympics and the 2003 International Skating Union Grand Prix Finals. Three-dimensional analyses of 14 split double twists and 15 split triple twists from eleven pairs were completed. In spite of considerable variability in the performance variables among the pairs, the main difference between the split double twists and split triple twists was an increase in rotational rate. While eight of the eleven pairs relied primarily on an increased rotational rate to complete the split triple twist, three pairs employed a combined strategy of increased rotational rate and increased flight time due predominantly to delayed or lower catches. These results were similar to observations of jumps in singles skating for which the extra rotation is typically due to an increase in rotational velocity; increases in flight time come primarily from delayed landings as opposed to additional height during flight. Combining an increase in flight time and rotational rate may be a good strategy for completing the split triple twist in pair skating.  相似文献

运用文献资料调研、现场测试、数理统计和对比分析等方法,对2008年在漳州集训的全国8支重点青年男子排球队13~20岁共计91名运动员的身高、体重和部分身体素质(助跑摸高、米字移动、三级蛙跳)进行测试,并对测试数据进行比较分析,结果显示,我国青年男子排球队运动员的身高条件较好,平均身高195.71 cm,最高达209 cm,有35人已达到了欧美强队的平均水平.但身高和体重发展极不平衡,克托莱指数低,身体肌肉充实度低、体重过轻是我国青年男排运动员当前在身体形态方面存在的主要问题,也是与世界诸强队无法抗衡的原因之一.我国青年男排运动员助跑攫高平均成绩与2002年时相比有显著性提高,但同成年队相比还有一定的差距;三级蛙跳成绩同成年队相比也有些差距;米字移动平均成绩为24.26 s,与2006年全国排球联赛男子运动员米字移动平均成绩24.51 s相比无显著性差异,但整体成绩仍发展不均衡.应抓住年轻运动员素质发展的敏感期,加强反应起动、灵活、协调性练习,提高反应时和肌肉内协调能力,提高运动员的速度素质.排球力量素质的发展应充分考虑其整体与局部的相互关系,应从整体上把握力量训练的比重,使力量全面均衡地发展.  相似文献

The aim of this study was to assess the relationships between various field tests in female athletes. Altogether, 83 high school soccer, 51 college soccer, and 79 college lacrosse athletes completed tests for linear sprinting, countermovement jump, and agility in a single session. Linear sprints (9.1, 18.3, 27.4, and 36.6 m) and agility tests (Illinois and pro-agility) were evaluated using infrared timing gates, while countermovement jump height was assessed using an electronic timing mat. Pearson's product-moment correlation coefficients (r) were used to determine the strength and directionality of the relationship between tests and coefficients of determination (r2) were used to examine the amount of explained variance between tests. All of the performance scores were statistically correlated with each other; however, the coefficients of determination were low, moderate, and high depending on the test pairing. Linear sprint split times were strongly correlated with each other (r= 0.775 to 0.991). The relationship between countermovement jump height and linear sprinting was stronger with the longer distances (27.4 and 36.6 m) than with the shorter distances (9.1 and 18.3 m), and showed a stronger relationship within the college athletes (r= -0.658 to -0.788) than high school soccer players (r= -0.491 to -0.580). The Illinois and pro-agility tests were correlated (r > or = 0.600) with each other as well as with linear sprint times. The results of this study indicate that linear sprinting, agility, and vertical jumping are independent locomotor skills and suggest a variety of tests ought to be included in an assessment protocol for high school and college female athletes.  相似文献
