正面双手原地前掷实心球是一项技术性很强的投掷项目,在练习和体质测试中往往见到不少学生由于身体素质较弱,再加上没有正确掌握实心球投掷技巧,成绩不是那么理想。那么如何提高投掷实心球的成绩呢？通过为期9年（3个循环教学）对我校学生原地双手前掷实心球的教学研究、训练实践中摸索出一点体会,并进行本研究,得出结论：1）反弓训练是双手原地前掷实心球教学的基础,他能够保证以后出手速度和出手角度操作的可行性也让学生对双手头上前掷实心球有个准确的切入点,大幅度的提高了学生投掷实心球兴趣与能力。2）根据人体肌肉用力特点和原地双手前掷实心球的投掷工作原理,从学生了的视角给出了一些双手头上前掷实心球超越器械形成满弓的训练方法,旨在抛砖引玉,与同行进行探讨,为学校体育教学的进步提出参考性的意见。 相似文献

原地正面双手头上前掷实心球于2010年被江苏省体育高考新方案确定为必测四项身体素质之一。至今实心球依然是很多考生的薄弱项目,据历年成绩显示,实心球较其他三项素质得分率偏低,大多数考生只能拿到及格分数。笔者将从考生的实心球技术学练、专项身体素质训练等方面展开讨论,总结原地正面双手头上前掷实心球的学练方法。 相似文献

近日拜读了<体育教学>杂志2005年第4期姜林老师的<双手头上掷实心球教学探析>一文,文中对原地双手头上掷实心球的脚的位置、引球(举球)以及发力过程中头的姿势等方面都作了详细的分析和学练的指导,对本人的教学起到了很好的指导作用,收获很大.但对文中提到的"影响实心球投掷效果主要取决于引球(举球)"这一观点,不敢苟同.现就本人多年来的教学心得,试对"原地双手头上掷实心球"的动作要领作以浅析. 相似文献

The aims of this study were to (1) investigate the influence of general anthropometric variables, handball-specific anthropometric variables, and upper-limb power and strength on ball-throwing velocity in a standing position (ν(ball)), and (2) predict this velocity using multiple regression methods. Forty-two skilled male handball players (age 21.0?±?3.0 years; height?=?1.81?±?0.07?m; body mass?=?78.3?±?11.3?kg) participated in the study. We measured general anthropometric variables (height, body mass, lean mass, body mass index) and handball-specific anthropometric parameters (hand size, arm span). Upper-limb dynamic strength was assessed using a medicine ball (2?kg) throwing test, and power using a one-repetition maximum bench-press test. All the variables studied were correlated with ball velocity. Medicine ball throwing performance was the best predictor (r?=?0.80). General anthropometric variables were better predictors (r?=?0.55-0.70) than handball-specific anthropometric variables (r?=?0.35-0.51). The best multiple regression model accounted for 74% of the total variance and included body mass, medicine ball throwing performance, and power output in the 20-kg bench press. The equation formulated could help trainers, athletes, and professionals detect future talent and test athletes' current fitness. 相似文献

The importance of proximal-to-distal sequencing in human performance throwing has been reported previously. However, a comprehensive comparison of the proximal-to-distal sequence in team-handball throwing in athletes with different training experience and competition is lacking. Therefore, the aim of the study was to compare the ball velocity and proximal-to-distal sequence in the team-handball standing throw with run-up of players of different skill (less experienced, experienced, and elite). Twenty-four male team-handball players (n = 8 for each group) performed five standing throws with run-up with maximal ball velocity and accuracy. Kinematics and ball trajectories were recorded with a Vicon motion capture system and joint movements were calculated. A specific proximal-to-distal sequence, where elbow flexion occurred before shoulder internal rotation, was found in all three groups. These results are in line with previous studies in team-handball. Furthermore, the results of the present study suggest that in the team-handball standing throw with run-up, increased playing experience is associated with an increase in ball velocity as well as a delayed start to trunk flexion. 相似文献

The purpose of this study was to examine the effects of calendar and skeletal age, anthropometric dimensions, training history and their interactions on vertical jumping height and horizontal overhead throwing velocity in a cross-section of 318 young male athletes (age range 9-16 years) participating in cross-country skiing (n = 70), basketball (n = 40), apparatus gymnastics (n = 19), ice hockey (n = 50), track and field (n = 89) and wrestling (n = 50). Vertical jumping height was measured with four different loads held on the shoulders and then interpolated for loads representing 0 and 40% body mass. Horizontal overhead throwing velocity using both hands was determined for seven balls of different weights and then interpolated for weights representing 1 and 5% body mass. Both vertical jumping height and overhead throwing velocity were found to increase (P < 0.01) from the skeletally youngest to the oldest cohort when the effects of body height and mass were controlled. The inter-event comparisons did not reveal statistically significant differences in respect of vertical jumping height. Also in the overhead throwing tests, the inter-event differences were small, although the analysis of variance revealed statistically significant (P < 0.001) differences for the skeletal age cohorts of 13 and 14 years. While the quantity of training had no effect on vertical jumping height, it explained the results in the overhead throwing test. The effects of training on vertical jumping and horizontal overhead throwing among adolescent athletes were considered to be small, while maturational processes and anthropometric development followed by increase in calendar age were deemed to be of greater importance. 相似文献
