摘要
本初步研究的目的是确定不同类别轮椅篮球运动员罚球技术的运动学因素。来自轮椅篮球俱乐部“Nais”的三名轮椅篮球运动员参加了这项研究。运动员按IWBF 1级、3级和4.5级进行分类。所有的参与者都是右撇子。在罚球线后距罚球线7.5 m, 25 cm处,面向篮筐的球员右侧1.20 m处,采用分辨率为1920 x 1080mm,每秒30帧的固定摄像机进行罚球投篮记录。采用“Kinovea”视频程序对轮椅篮球运动员罚球技术的训练结果和运动数据进行处理。运动学参数显示了1、3、4.5级轮椅篮球运动员罚球技术表现的差异。1、3、4.5班学员投掷成功率的差异为:投球角度为50°、52°、47°,投球速度为7.58 m/s、6.25 m/s、7.27 m/s,投球高度为164.49 cm、180.71 cm、190.86 cm,肘部时间参数和角度相同。我们可以得出结论,篮球运动员要想成功地完成罚球技术,需要在最终位置达到更高的投球高度。
A Biomechanical Analysis of the Free Throw Shooting Technique in Wheelchair Basketball: A Pilot Study
The aim of this pilot study is to determine the kinematic elements of the free throw shooting technique among wheelchair basketball players from various classes. Three wheelchair basketball players from the wheelchair basketball club “Nais” took part in the study. The players were classified from IWBF classification 1, 3 and 4.5. All of the participants were right-handed. Free throw shooting recording were made with a fixed camera with a 1920 x 1080р resolution, 30 frames per s, positioned at a height of 1.20 m on the right side of the players facing the basket, at a distance of 7.5 m and 25 cm behind the free throw line. The “Kinovea” video program was used to process the results and the kinematic data for the free throw shooting technique of wheelchair basketball players. The kinematic parameters indicate differences in the performance of the free throw shooting technique among wheelchair basketball players from class 1, 3 and 4.5. A difference in successful throws between the participants from class 1, 3 and 4.5: the angle of ball release 50°, 52° and 47°, velocity of ball release 7.58 m/s, 6.25 m/s and 7.27 m/s, and height of ball release 164.49 cm, 180.71 cm and 190.86 cm, while the temporal parameters and angles of the elbow had the same values. We can conclude that for the successful performance of the free throw shooting technique a basketball player needs to achieve greater height of ball release in the final position.
