“…According to sports experts' opinion and scientific researches, coordination of movements is tightly connected to other types of coordination abilities and, first of all, to the ability of evaluating and regulating dynamic, spatial and timing parameters of movements [18,20,23]. The development of experimental complexes [1,10,22,24]. It is related to the fact that along with enhancing the athletes' qualification, the generalization and positive shifting in the sphere of abilities and motor skills reduces.…”

Background and Study Aim. The aim of the research is to investigate the efficiency of designed complexes of training exercises aimed to improve the coordination abilities of qualified athletes in fencing. Material and Methods. 22 qualified athletes specializing in fencing aged from 15 to 18 took part in the research. The study design included the sequential pedagogical experiment that was realized through the several stages. At the first stage, the preliminary testing of the athletes’ coordination abilities (n=22) was conducted. During the preliminary testing the following tests were applied: jumps to the line; shuttle run (4x9 m.); T-test, straight touch from en-garde position to the target of 10 cm in diameter from close range (10 attempts); straight lunge attack from en-garde position to the target of 10 cm (10 attempts). At the second stage of the pedagogical experiment two complexes of exercises aimed at developing the coordination abilities of the athletes were applied for 3 months. The experimental complexes of exercises were used twice a week. At the third stage, the efficiency of experimental complexes aimed at the developing of coordination abilities of qualified athletes in fencing was checked through a control testing. The Statistica 10 software created by the StatSoft Company was used for statistical processing of data. Results. It was established that during the process of coordination abilities development, the greatest attention should be given to the athletes’ ability to control timing, spatial and physical parameters of moves and moves consistency. To improve the process of developing the coordination abilities of the qualified athletes in fencing two complexes of training exercises were developed. The results of the pedagogical experiment confirmed the statistical differences in the levels of the athletes’ coordination abilities manifestation before and after using experimental training complexes (p<0.05). Conclusions. It has been shown that specially developed training complexes could be used during the training process in order to develop and increase the level of coordination abilities of qualified athletes in fencing. The analysis of experts’ opinion showed that the development of coordination abilities in fencing should be oriented towards the development of athletes’ ability to control timing, spatial and physical parameters of movements.

“…In addition, Hykso tends to overestimate RUC against the RS and RH. The boxing punch involves the full-body kinetic chain ( 12 ) where the ankle, thigh, trunk, forearm, and hand must move in a coordinated fashion ( 14 ). Therefore, each punch type requires a unique coordination pattern and punch trajectory ( 9 , 20 ).…”

Omcirk, D, Vetrovsky, T, Padecky, J, Malecek, J, and Tufano, JJ. Validity of commercially available punch trackers. J Strength Cond Res 37(11): 2273–2281, 2023—This study determined how well data from commercially available punch trackers (Corner, Hykso, and StrikeTec) related to gold-standard velocity and force measures during full-contact punches. In a quasi-randomized order, 20 male subjects performed 6 individual rear straight punches, rear hooks, and rear uppercuts against a wall-mounted force plate. Punch tracker variables were compared with the peak force of the force plate and to the peak (QPV) and mean velocity (QMV) assessed through Qualisys 3-dimensional tracking. For each punch tracker variable, Pearson's correlation coefficient, mean absolute percentage error (MAPE), and mean percentage error (MPE) were calculated. There were no strong correlations between punch tracker data and gold-standard force and velocity data. However, Hykso “velocity” was moderately correlated with QMV (r = 0.68, MAPE 0.64, MPE 0.63) and QPV (r = 0.61, MAPE 0.21, MPE −0.06). Corner Power G was moderately correlated with QMV (r = 0.59, MAPE 0.65, MPE 0.58) and QPV (r = 0.58, MAPE 0.27, MPE −0.09), but Corner “velocity” was not. StrikeTec “velocity” was moderately correlated with QMV (r = 0.56, MAPE 1.49, MPE 1.49) and QPV (r = 0.55, MAPE 0.46, MPE 0.43). Therefore, none of the devices fared particularly well for all of their data output, and if not willing to accept any room for error, none of these devices should be used. Nevertheless, these devices and their proprietary algorithms may be updated in the future, which would warrant further investigation.

“…The upper extremity was preferred to the lower extremity because the lower extremity was relatively static compared to the upper extremity (Tong-Iam, Rachanavy & Lawsirirat, 2017). The efficiency of a punch in boxing largely depends on the dynamics of velocity of body segments carrying out movements in multi-link systems of the human body (Gu, Popik & Dobrovolskiy, 2018). Based on the above mentioned, it is also required to engage a muscle chain as much as possible in order to have a strong punch.…”

PURPOSE: Performance in boxing is a combination of strength, speed, and stability to create maximum impact. One of the types of punches commonly used in boxing is the straight punch. The magnitude of force exerted at the point of impact is influenced by a number of factors. Therefore, some biomechanical parameters can have greater effect than others during punch performance. Likewise, different technique modalities influence punch force. This study aims to determine differences between kinetic and kinematic parameters of punches performed with two different techniques (with and without weight shifting). METHODS: Overall, 20 straight punches were performed (10 for each observed technique) by a top-level female boxer (26.1 years old, height 170.3 cm, weight 63.2 kg). Afterwards, four kinematic variables (shoulder, upper arm, forearm, and hand velocities) were analyzed together with the position of center of mass (Xsens, Awinda). Also, overall foot pressure force of both feet (Novel pressure insoles) was analyzed for each technique, as well as the impact force of each punch (Punchsensor). Differences between the techniques were determined by MANOVA. RESULTS: Significant differences were found in foot pressure force and impact force, with higher values of punch force determined in the straight punch performance that includes weight shifting (p=0.00). Regarding kinematic parameters, there were significant differences in shoulder velocity, forearm velocity, and center of mass position (p=0.00). Upper arm and hand velocity variables did not differ significantly. This result indicates that different punch preparation can exhibit greater force and better performance. CONCLUSION: The understanding of movement pattern in punching could provide insightful instruction to coaches and boxers on how to generate powerful straight punches. The presented data objectively determined differences between two approaches in performing a straight punch which could help in correcting technical performance.
