“…For example, traditional action recognition methods have static features based on shape and contour, and dynamic features based on optical flow and motion information. e study in [12] aims to achieve action recognition by doing shape matching of key video frames extracted from the video with the saved original action. e study in [13] computes the optical flow field of a target in a video using fuzzy optical flow features and achieves online action recognition by template matching.…”

With the improvement of living standards around the world, people's love for sports has also increased; basketball is especially loved by people. It is of great importance to provide sound motor instruction for basketball. To this end, this paper comprehensively investigates the dependence between the optimal release conditions and the corresponding shooting arm movements in basketball players. We carry out kinematic feature analysis of basketball sports videos, propose a hybrid CNN-LSTM model that can predict the arc of the shooting parry, and identify the key movements of the arm joint that produce optimal release velocity, angle, and backspin in short-, mid-, and long-range shots. The experiment demonstrates that the model has three rigid planar links with rotational joints that mimic the shoulder, elbow, and wrist joints of the upper arm, forearm, and hand, which are better at guiding the optimal ball release speed, angle, and backspin for different players with the fastest ball speed being about 4.6 m/s and the slowest being about 1.7 m/s.

“…The assumption is that the shot speed will be extended when shooting from greater distances because players need more muscular strength and coordination to perform shots, but, considering the influence of fatigue, both parameters will be disturbed (Enoka & Duchateau, 2008;Jarić et al, 1997). This explanation is corresponding to previous studies reporting that the shot speed was decreased when the distance increased (Rupčić et al, 2015;Vencúrik et al, 2021).…”

Few studies investigated the influence of fatigue on the change of kinematic parameters in basketball shooting regarding female players. This study aimed to determine the difference of kinematics in basketball jump shot between non-fatigue and fatigue conditions. Thirty-two professional female basketball players volunteered to take part in the study (age: 22.11 ± 4.92 years; height: 173.99 ± 7.06 cm; weight: 67.89 ± 5.65 kg). 3D motion analysis using an inertial suit and a smart ball were performed for measuring the kinematic parameters. The results demonstrated that there were no significant differences in angular velocity of ankle, knee and hip joints. Conversely, differences in angular velocity of elbow (p = 0.036) and wrist (p = 0.002) were detected. In addition, the results showed that the release height and entry angle of the ball significantly decreased in fatigue condition, suggesting that coaches need to include in the training process exercise that is similar in terms of fatigue and performance to the situational condition during the game as these two variables play an important role in the determination of shooting efficiency.

“…Previous studies have reported that three-point shot accuracy correlates with upper limb strength [ 28 ] and power [ 29 ]. It has also been reported that youth players shoot with a lower shoulder angle than senior players [ 30 , 31 ]. It is speculated that the lower shoulder angle compensates for a lack of muscle strength, and the compensatory movement might have detrimental effects on shooting technique development.…”

This study aimed to investigate the changes in shot distribution and accuracy in senior and under-17 international basketball tournaments in the 2010s. A retrospective cross-sectional design was employed, and a total of 1055 games from 20 world-level tournaments held between 2010 and 2019 were analyzed. The tournaments held in 2010 were played under the old three-point line (6.25 m), and the rest of the tournaments were played under the new three-point line (6.75 m). The numbers of two- and three-point shot attempts in each game were normalized to 100 possessions. Differences in mean values of two- and three-point shot attempts were analyzed by a two-way (category × year) between-subjects analysis of variance (ANOVA). Differences in the success rates of two- and three-point shots were analyzed by Fisher’s exact test. There was no significant category × year interaction for two-point shot attempts. However, there were significant main effects of category and year for two-point shot attempts. The number of two-point shot attempts increased significantly in 2012 and, in 2016, returned to a level not significantly different from that in 2010, independent of categories. There was a significant category × year interaction for three-point shot attempts. The number of three-point shot attempts decreased significantly in 2012 and, by 2016, returned to a level not significantly different from that in 2010 in senior men and under-17 women. There was no significant change in the number of three-point shot attempts in under-17 men. The effect of the extension of the three-point line on shot accuracy was limited. Differences in shot accuracy were prominent between age categories: the accuracy was lower in under-17 games than in senior games for both sexes. Although under-17 men attempted fewer three-point shots than senior men, under-17 women attempted a similar number of or more three-point shots than senior women. These findings can contribute to a better understanding of age and sex differences in recent trends in international basketball.
