Some kinematics aspects of throwing applied to basketball
New Trends and Issues Proceedings on Humanities and Social Sciences , 2017
Kinematic simulation of sport movements can be considered as an investigation tool for sport scientists. The throw is a motion that most of players, especially from team sport will perform for a hundreds of time in a practice. Sports biomechanics research technique aims to elucidate the improvement of shooting technique in the game of basketball, to improve effectiveness. Motric gesture improvement depends on analyzing the technical execution of it, sequential observation by analyzing each phase of the movement. This study aims to examine aspects of throwing kinematics in sports in general and basketball in particular. For analysis the free throws we used video analysis method and mathematical modeling. Knowledge of kinematic parameters of a throw can contribute to realizing a dynamic model of throwing which ends with modeling the training and achieve the performance. For that we analysis the free throw model and we conclude that it has a stereotypical shooting pattern for all players evaluated and is characterized by a proximal and distal in joint motion for upper and lower body The free throw is characterized by a pattern of angular velocity which varies depending by the joint motion during the release phase.
Kinematic Analysis of the Basketball Free Throw in Preparation Phase of Elite Athletes
International Journal of Human Movement and Sports Sciences, 2021
The purpose of this study was to analyze the kinematic parameters of the body for the preparation phase of the free throw to improve the efficiency and sport performances. The study includes a total twenty elite basketball players from the Kosovo Super League teams: K.B. Prishtina, K.B. Kerasani and K.B. Lipljan. Basketball shooting measurements were conducted during the training of the 2018 year. Filming of the basketball shooting techniques is done with three Canon HD cameras, set at 90-degree angles, which can reproduce sixty pictures per second. 12 variables of kinematic parameters of body were selected for analysis. Only one successful shot from each player was taken for analysis. Analysis is done with Kinematic Analysis System (APAS), outputting the required results and values of the kinematic indicators. The data collected were processed by statistical analysis software "IBM SPSS 20", and statistical parameters were determined using the methods: arithmetic mean, standard deviation, minimum score, maximum score, Skewness and Kurtosis. The confirmation of the mutual influence of the variables was done by the Pearson's coefficients correlation method. The findings of this study show that in the preparation phase for a free throw shot in basketball, variables such as knee angle, wrist angle, thigh angle, and elbow angle have shown to be the kinematic parameters that have the greatest impact on finalizing a successful free throw in basketball. The scientific contribution of this research also provides new insights into the optimal model of basketball player performance during free-throw.
Kinematic Analisis of the Jump Throw in Basketball
Isbs Conference Proceedings Archive, 2007
The aim of this study was to analyze kinematically the jump throw movements of adult category players. The sample of this study was done by ten players. For the kinematic analysis, it was used a bidimensional video graph system and the Jump Test system to analyze the vertical jump. Within the analyzed variables, the angle of elbow extension in the moment of ball release was a value of 126,67 ± 9,42º, which was not verified a significant difference related to other studies. In the variable projected angle of the ball it was observed an average value of 54,75 ± 2,48º, with a significant difference related to other studies. The jump throws has a low technique rate, because only 40% of realized throws had success.

Kinematic Analysis of Basketball Jump Shot
Technique in sport is defined as rational and efficient performance of movement aimed to resolve motoric tasks in the training and competition process. Insight into the available literature resulted in selection of 3 kinematic variables used for analysis: release angle, release velocity and release height. Consequently, aim of this research is systematic review of kinematic parameters influencing the success of performance in basketball jump shot. Throwing angle is considered to be the most important factor for success of jump shot. Increased release angle is in correlation with the height of basketball trajectory which renders it a function of increased angle of entry of the basketball. Increased angle of entry enables the maximum use of the basket ring but demands increased release velocity. It is possible to control the release velocity using the spin created by the wrist flexion. Second manner of regulation of the velocity is increased release height. Influence on the release height is, however, reduced because it is determined by the constant basket ring height, player's height, jump height and organisation of segmented movements of body parts. Understanding the interaction of variables influencing the structure of basketball movement in duration of shot provides insight into the complexity of movement performance in basketball. It is therefore necessary to indicate these variables during trainings, which is possible under the current conditions due to the fact that the technology has advanced significantly in past few years and follow-up of the said parameters demands very little effort.
The study aimed at revealing the linear kinematical variables responsible for a successful free shot in basketball. Five subjects of homogenous nature in terms of anthropometric measurements and training age was selected. Casio Exilim EX-F1 high speed camera was used for recording of performance and Silicon Coach pro 7 software and Kinovea software were used for the analysis of data. The patterns values were superimposed which revels that there exists a difference in pattern of successful and unsuccessful free throws.
Biomechanical Analysis of Ball Trajectory Direction in Free Throw
Proceedings of the 1st International Conference on Education Social Sciences and Humanities (ICESSHum 2019), 2019
Basketball game is decided by the most point counted from successful shooting. Moreover, free throw is one of many shooting techniques which is frequently used in basketball game. So, the aims of this research are reviewing the ball trajectory direction to find the formula to increase possibility of successful shooting and decrease shooting error possibility. This is a quantitative study with independent t-test data analysis by SPSS. There are 73 male college physical education students(age : 20 1.2 years) who were categorized based on their height in to 5 groups. Each of them tried to make 3 successful free throw. The result, there are significant different of ball direction, launching angle, maximum elevation, and ball velocity among different height group (< 0.05). In the conclusion, the launching angle and maximum elevation among different height group has different characteristic. However, the ball direction and velocity have more similarities among different height group.

A Kinematic Analysis of the Basketball Shot Performed with Different Ball Sizes
Applied Sciences
In youth basketball, the ball’s size is adapted to fit the participants’ physical capacities and improve the development of manipulative skills. The current study compared the kinematic parameters of the basketball shot (BS) performed with two different ball sizes. Twenty-seven adolescent females aged 12.1 ± 0.9 years (height: 153.3 ± 8.0 cm; body mass: 48.8 ± 12.8 kg) completed 10 BS trials from a frontal position at 5.75 m from the basket with two ball sizes: a smaller and lighter ball (size five, 480 g) and the standard ball size for their age (size six, 566 g). No statistically significant differences were observed for ball release variables or efficacy levels. Significantly greater shoulder flexion was detected at release while shooting with a size six ball (F = 2.982, p ≤ 0.01). The shoulder’s angular velocity at release was significantly lower while performing with a size six ball (F = 3.089, p ≤ 0.01). No significant differences were found for the elbow or knee angles or ang...
Kinematic Differences Between Proficient and Non-Proficient Free Throw Shooters – Video Analysis
Journal of Applied Sports Sciences, 2021
Despite its importance and signifi cant contribution to the fi nal game outcome, the free throw shooting motion is greatly understudied. The purpose of this study was to examine kinematic differences between profi cient and non-profi cient free throw shooters and to determine which variables have the greatest impact on successful free throw shooting performance. Thirteen healthy recreationally active males volunteered to participate in this study. Each participant shot three sets of ten consecutive free throws from the regulation distance from the basket. Each set was performed under 3 minutes with 1-2-minute rest between each set. A high-defi nition camera recording at 30 fps captured the free throw shooting motion from a sagittal point of view. Video analysis software was used to analyze the following kinematic variables: knee angle, elbow angle, hip fl exion, ankle fl exion, release angle, shoulder angle, hand release height, and elbow height. The fi ndings of this study suggest that lower elbow positioning infl uenced by greater knee, ankle, and hip fl exion during the preparatory phase of the shooting motion may lead to improvements in free throw shooting accuracy. Moreover, greater ball release height and release angle, as previously suggested, could decrease the margin of error and enhance free throw shooting performance. By using these kinematic variables to create the discriminant function projection model, it is plausible that profi cient free throw shooters can be accurately classifi ed in 94% of cases.
