El efecto de la vibración aguda en el tiempo de reacción visual en esgrimidor

The purpose of this study is to determine the effect of an acute local vibration exercise on the visual reaction time of a fencer’s upper body extremities. Twenty-six male fencers between the ages of 15 and 23 (mean age, 17.38 ± 2.13 years, height: 173.6±9.1 cm, body mass: 70.2 ±14.1 kg) volunteered for this study. The reaction time test was applied before and after the vibration exercise (applied for 30 seconds in 27 Hz with a 2-mm amplitude). After 25 min. standard warming up, fencers were informed about the test, and three repeated reaction tests were performed to provide familiarization. The fencers started the reaction test in the standard fencing guard position. According to five signals coming at two to five second intervals from the target monitor, the fencers made touché by bending (attacking). The reaction time test had five trials. The average reaction time values pre-vibration, and post-vibration were compared. The visual reaction time measured pre-vibration were significantly longer than those measured post-vibration (p<0.001). Acute local vibration exercise applied to fencers shortened the visual reaction time. Given the fact that vibration can improve RT, the use of vibration in training has the potential to provide an advantage to fencers.El propósito de este estudio es determinar el efecto de un ejercicio de vibración local aguda en el tiempo de reacción visual de las extremidades superiores de un esgrimidor. Veintiséis esgrimidores masculinos entre las edades de 15 y 23 (edad media, 17.38 ± 2.13 años, altura: 173.6 ± 9.1 cm, masa corporal: 70.2 ± 14.1 kg) se ofrecieron como voluntarios para este estudio. La prueba del tiempo de reacción se aplicó antes y después del ejercicio de vibración (aplicado durante 30 segundos en 27 Hz con una amplitud de 2 mm). Después de 25 min. calentamiento estándar, se informó a los esgrimidores sobre la prueba y se realizaron tres pruebas de reacción repetidas para proporcionar familiarización. Los esgrimidores comenzaron la prueba de reacción en la posición estándar de protección de esgrima. De acuerdo con cinco señales que vienen a intervalos de dos a cinco segundos desde el monitor objetivo, los esgrimistas hicieron un toque al doblarse (atacar). La prueba del tiempo de reacción tuvo cinco ensayos. Se compararon los valores promedio de tiempo de reacción pre-vibración y post-vibración. El tiempo de reacción visual medido antes de la vibración fue significativamente mayor que el medido después de la vibración (p <0.001). El ejercicio de vibración local aguda aplicado a los esgrimidores acortó el tiempo de reacción visual. Dado que la vibración puede mejorar la RT, el uso de la vibración en el entrenamiento tiene el potencial de proporcionar una ventaja a los esgrimidores

Evaluation of scores of the 33rd and 34th Junior European Championships in Men's Artistic Gymnastics

To determine the effects of difficulty (D), execution (E), and total score of the apparatus on the all-around total score, and compare the scores of the 33rd and 34th Junior European Championships in Men's Artistic Gymnastics (JECMAG). The data of the study are the all-around scores of the final of the 33rd (2018) and 34th (2020) JECMAG. The all-around total score (AATS), apparatus total score, D and E score of each apparatus were evaluated. A multiple regression was run to predict AATS20 18 from the total score of the vault, pommel horse, horizontal bar, floor exercise, parallel bars, and AATS2020 from the parallel bars (p<.001). Multiple regression analysis was run to predict AATS201 8 from scores of vault D, pommel horse D, vault E, horizontal bar E, horizontal bar D, pommel horse E, floor exercise D scores and AATS202 0 from parallel bars D, parallel bars E, pommel horse E scores (p<.001). In the 34th JECMAG, there were significant decreases in AATS and some apparatus scores compared with the 33rd JECMAG. Although the effect of apparatus scores changed according to the competition dynamics, the most important apparatus seemed to be the vault (2018) and parallel bars (2020). It can be concluded that D scores were better predictors than E scores. Coaches can take these findings into account when determining competition strategies

A COMPARISON OF TIME OF FLIGHT AND HORIZONTAL DISPLACEMENT SCORES IN TRAMPOLINE GYMNASTICS ROUTINES

In trampoline gymnastics, elements with low difficulty values are given more place in the first routines in accordance with the international competition rules. In the second routines, because the difficulty value of all the elements performed earn points for the gymnast, elements with high difficulty values are preferred. This difference may affect other score types in the routines. Accordingly, the aim of this study was to compare the time of flight and horizontal displacement scores in first and second routines. The results of the 2019-2020 Trampoline Gymnastics Turkish Championship constituted the data of the study. In both competitions, both the entire group and the female and male groups were evaluated. Except for the 2019 male horizontal displacement scores, the time of flight and horizontal displacement scores of all groups were found to be statistically significantly lower in the second routines compared with the first routines (p<0.05). According to these results, the trampoline gymnasts preferred more complex and difficult elements to obtain high difficulty scores in the second routines in accordance with the international rules, which may have caused them to achieve lower time of flight and horizontal displacement scores compared with the first routines. Trainers and gymnasts should aim to increase the difficulty score without decreasing the total score while choosing elements for second routines. To find this difficulty level, trainings and trial competitions can be performed with routines with different difficulty scores

The effect of score types on total score in trampoline gymnastics:Example of the European Championship in Sochi 2021

Background and Study Aim Trampoline gymnastics has a versatile scoring system that has evolved and become more complex over the years. This study aimed to find the effect of the difficulty (D), execution (E), time of flight (TOF), and horizontal displacement (HD) scores on the total score in male and female trampoline gymnasts
