“…A smooth and continuous pole drop allows a good posture and is used as a method to increase velocity and acceleration of the approaching take-off. Conversely, if the pole drop is less smooth, the torque of the pole will increase the load on the athlete's body ( Yang et al, 2021 ). It could be that, at the failed attempts, athletes dropped the pole too fast, an action that caused the athlete’s trunk to be pulled forward and was counteracted by shortening their step, which eventually led to a further increase in the vertical impulse and SF turnover of the PC leg.…”

The purpose of the study was to identify the interaction of step characteristics, along with the direction and magnitude of their asymmetry of elite male and female pole vaulters between successful and failed attempts. It was hypothesized that step characteristics and the magnitude of asymmetry between the two legs would interact with the outcome of the attempt. The approach runs of 12 pole vaulters (7 males, 5 females) were recorded during an indoor international competition. The leg used by the athlete for taking-off was defined as the non-pole-carrying leg, while the other was the pole-carrying leg. Using spatiotemporal information obtained from recordings with a panning camera (300 fps), the last steps of each athlete's approach run were analyzed for length, frequency, average velocity, and inter-limb asymmetry. There was no inter-limb difference (p > 0.05) in the absolute values of step length or step velocity between successful and failed attempts. However, the pole-carrying leg presented significantly (p < 0.05) higher step frequency values at the failed attempts. There was no significant difference (p > 0.05) in asymmetry values for step length, frequency, and average velocity between successful and failed attempts. Although step velocity remained unaffected, failed attempts were characterized by a perturbation in the interaction of step frequency and step length. The present findings suggest that although high velocity at the final phase of the approach is essential, it is not the sole determining factor for a successful attempt.

“…The methodology for modeling competitive activity has been widely developed in cyclic sports: in athletics (Dobrynskaya & Kozlova, 2013;Morais et al, 2014;Lundstrom et al, 2017;Yang et al, 2020); in swimming (Barbosa et al, 2010;Platonov, 2011;Skirenya, 2009).…”

Modeling of competitive activity forms the basis for the rationalization and improvement of those means and methods that are used in sports training of athletes. In this regard, a hypothesis was put forward that predictive skating models will ensure the achievement of a certain level of sports results in short-track speed skating. Study purpose. The aim of the study was to develop a prognostic model of the competitive activity of elite athletes at a distance of 500 m in short-track on the basis of regression analysis with a focus on achieving specified results. Materials and methods. The study used an analysis of official competition protocols, modeling method, statistical analysis. The behavior of changes in the speed of skating at a distance of 500 m in 173 elite athletes was analyzed. The main components of competitive activity in short-track were revealed. Results. The results obtained have theoretical significance which lies in the scientific substantiation of the need to improve competitive activity on the basis of its studying and the building of skating models. Their practical significance consists in the development and use of models of competitive activity of elite athletes at a distance of 500 m in short-track, taking into account the construction of a skating option. The presented data are an action plan that allows you to purposefully manage the training process and improve the training of athletes in short-track speed skating at a distance of 500 m in an annual cycle. When processing the results of the study, the level of statistical significance was taken as p ≤ 0.05. Conclusions. The informative characteristics of competitive activity that affect the result at a distance of 500 m include acceleration speed and running speed on the first, second, third and fourth laps of the distance, multiple correlation coefficient r = 0.985 (p < 0.01). These are objective criteria which are a system-forming factor that determines the structure and content of the training process of elite athletes, and allow monitoring the level of special readiness, as well as predicting the ways of further improvement and making timely corrections in the training process.
