“…On the one hand, it agrees with other recent papers (Abdelkader, Madani, Adel, et al, 2018;R. M. Bartlett, 1992;Frossard et al, 2013b;Leigh et al, 2010) and computational simulations for the kinematic angle values close to this study (Sueyoshi and Maruyama, 1992). On the other hand, these differences in the timing of movement for each athlete indicates the specific characteristics of kinetic performance according to his medical classification and degree, and this causes a discrepancy in the distribution of time along the technical stages of discus throwing.…”

The aim of this study is to analyze kinematical variables of discus throw activity in Para-Athletics F57 and to investigate their relationships with digital level achievement. International Para-athlete "Saifi Nassima" participated voluntarily in this study. The athlete throwed the discus with her right arm. Recordings were made by synching cameras (AEE MagicCam, 170° view, MOV Format Video, 720p Video Resolution, 120 ips NTFS, Screen Resolution 1280*720 16:9) for side and rear views by a LANC (CONTROL-L) device. The athlete wore reflective markers to track their motions on joints of the wrists, the elbows, the shoulders, the hip center, and down the neck with the least possible number of occlusions, to analyze the length and angle of movement by the x and y axis. The best six throws during the first and second phases (start and finish throwing) of the discus throw were included for analysis in two-dimensional by Dartfish.9 software. Means, standard deviations, minimum and maximum values were applied as descriptive statistics, and Pearson test for the correlations between all variables. As a result, there was a positive significant correlation of digital level with cubitus angle of the throwing hand (p< .001), trunk angle (p< .005) in the first phase, and with disk flight time (p< .005), throwing angle (p< .001) in the second phase. In conclusion, we confirm that the increase in the values of the variables of distance shot from the armrest, and the wrist angle of the shooting hand in the first phase of throwing, affects the digital level achievement. The decrease in the value of the throwing angle variable in the second phase of throwing affects the digital level achievement.

“…In another study, it is put forward that the optimum height of release is 90% of thrower's height [ 22 ], while Bartlett think that 93% of thrower's height is the best release height. Of course, in addition to technical parameters, there are anthropometric indicators such as athlete's height and arm length of athletes [ 1 ]; other studies also indicate that the height of release is important to performance of discus throwing [ 23 , 24 ].…”

The purpose of this study was to examine the difference of kinematic skill characteristics between the Chinese and world elite female discus athletes. We used the methods of literature, three-dimensional video analysis, and mathematical statistics to compare and analyze the differences of some kinematic parameters between the three Chinese female discus athletes and four world female discus athletes. The result shows that the speed of discus release of the Chinese elite female discus athletes is lower ( p < 0.05 ) than that of the world elite female discus athletes. Compared to the world elite female discus athletes, the height of release is higher ( p < 0.05 ). But there was no significant difference in the angle of release ( p > 0.05 ), rotation rhythm ( p > 0.05 ), and discus speed increment ( p > 0.05 ) in different stages during the throwing procedure from double support stage to delivery stage. The results may provide reference for the special technique training of the Chinese female discus throwers, so as to improve the discus throwing level of Chinese women.

This study presents a new way to improve technical training in para-athletic disciplines (for athletes with musculoskeletal disorders). The experimental group included 5 men and 1 woman. 5 athletes were preparing to perform in shot put, 2 athletes were preparing to perform in discus throw and 5 athletes were preparing to perform in javelin throw. An algorithm for technical training was developed, comprising three stages. The first stage includes high-speed video recording of the performed exercises in the front plane (from the front, from the back), sagittal plane (from the right, from the left), and transverse plane using a video camera attached to the quadcopter. The second stage includes synchronization of video recordings, recognition of markers, and obtaining 3D biomechanical model of the exercise. The third stage includes the analysis of kinematic characteristics of equipment of competitive exercises with the subsequent interpretation and comparison with the model characteristics revealed earlier by identification of parameters of available motor actions. The recommendations for updating the individual locomotion in the activity and guidance on the selection of major exercises were elaborated. According to the developed algorithm, six measurements were performed in each competitive discipline during the preparatory period of 2 months. After identifying the reserves of equipment, the technique was corrected in each competitive exercise, and the individual recommendations for optimizing the technique were given. At the end of the experiment, the average improvements of athletes were 0.85±0.13 m in discus throw (n=5, P<0.01), 3.15±0.69 m in shot put (n=2, P<0.05); 2.53±0.41 m in javelin throw (n=5, P<0.001). At important competitions at the end of the experiment, the athletes set 10 personal records.
