Relationship of Kinematic Variables with the Performance of Basketballplayers in Lay-Up Shot
Citius Altius Fortius, 2009
The purpose of the study was to determine the relationship between selected kinematic variables and performance of lay-up shots. Five (N=5) male basketball players who represented Punjab Technical University, Jalandhar, were selected as subjects for the study. The help of digital photography was used to film the subjects in sagittal plane of lay-up shot. Joint point method was used in order to obtain the values of selected angular kinematic variables from developed stick figures. Height of center of Gravity was calculated by segmentation method. The performance in Lay-Up Shot was recorded by the scores in Lay-Up Shot, which was obtained by using a three point scale by the three judges. To determine the degree of relationship between selected kinematic variables with the performance in Layup Shot, Pearson's Product Moment Correlation Method was used. The results have shown the insignificant values of coefficient of correlation incase of all the selected kinematic variables and significant relationship between the height of center of gravity at the moment of release with the performance of the subjects in lay-up shots.
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.

Thirty (N=30) Basketball player of Basketball academy from NBA Academy Indore are purposively selected as a subject for present study. Further it was divided into three different heights groups of Ten (N=10), subjects each, the first group was heighted from 155 to 165 cm, second group was heighted from 166 to 175 cm and third group was heighted from 176cm and above respectively. The entire subject ranged between ages 15 to 21 years. Videography method was used to biomechanically analysis the selected moments i.e. execution of Jump shot in Basketball. The selected kinematic variables such as Displacement of CG, player's CG height during ball release and velocity of the ball during ball release were selected for the present study. Kinovea software was used in order to obtain the values of selected kinematic from developed stick figure. For the purpose of this study ANOVA test was used. The level of significance was set at 0.05. The result reveled significant difference in player's cg height during ball release but the researcher failed to get the significant result in displacement of cg and velocity of the ball during ball release.
Kinematic assessment of the vertical jump in young basketball players
Journal of Physical Education and Sport, 2020
Problem statement Jumping is a Fundamental Movement Skill and a milestone for motor development. It is well known that this performance relates to the features of the considered population. In the sport practice, the jump is a component to assess physical abilities. Furthermore, basketball players are exposed to many injuries because of the jump rate, such as ankle or knee sprains. Approach Sixty young basketball players aged between 8.3 and 12.6 years (37 males, 23 females) participated in this study. An ecologic assessment protocol to investigate the specific vertical jump pattern of this sample was set up in the basketball gyms. An anamnestic questionnaire, BMI, and kinematic assessment were used. Purpose The aim of this cross-sectional study is to describe the specific kinematic jumping pattern in young basketball players. Results Data support the importance of a child-specific kinematics analysis of the vertical jump. The lower quadriceps strength and the larger flexibility of ankles in children justify the large involvement of this joint during the vertical jump (down 25.3°, up 24.1°, flight 7.4°, landing 26.4°). Multiple linear regression demonstrates that the movement of the hip during flight is significantly influenced by age (p-value=0.04), especially in males (p-value=0.02). In addition, the movement of the knee during flight is significantly related to BMI in males (p-value=0.01). Conclusions New data about the specific jumping pattern of young basketball players are provided to create adapted and appropriated prevention protocols. Young basketball players show a specific immature motor pattern during the vertical jump.
UNSUPPORTED SHOT BIOMECHANICS SPECIFIC FOR DIFFERENT SKILL LEVELS IN BASKETBALL
There is a wide variety of shots in basketball, but 70% of all shots in the game are done using one hand in a jump (jump shot). It is important both for professional basketball players and for successful workouts of beginner players (students, pupils) to improve this type of shot, as it influences the psychological aspect of success in the game, and therefore the training process. At the same time, in the context of sports physiology unsupported position is not a standard condition for any motor action, and one needs a complex overall restructuring of functional systems to adapt to it. The specifics of the jump shot biomechanics depending on the skill levels of basketball players acting in the unsupported positions was studied. The results indicate that the restructuring of the set of movements of highly skilled basketball players provides first adaptation to the unsupported position, coordination of movement and turn the aerial position of the body into a technical skill. At the same time, the physiological adjustment of body systems to the unsupported position during a jump shot is a factor generating aspect that has an adverse complex effect on the quality of performance of this motor action.
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.
