Use of psychophysiological computer tests during the process of sportsmen’s preparation

Abstract

Psychophysiological computer tests are widely accepted in sports science, because they are fast and not expensive. In this study, a new program for computer testing is presented which allows us to find the average reaction time of a sportsman in different directions and estimate his/her reaction symmetry coefficient. On the basis of these parameters recommendations to coaches and sportsmen are given for the future training. The main feature of the program is its design perfectly fitted into reality which contributes to more effective and persistent changes in the reaction skills of a sportsman. On the example of a group of ten 17-19 year old sportsmen with low-medium qualification the improvement of choice reaction time by 10% on the average is demonstrated onemonth after a special training including the computer tests for about 10-15 minutes daily. The method has proved to be effective for improving sportsmen's reaction, attention, concentration, coordination and peripheral vision and should be taken by athletes regularly to develop fine motor skills. Tests for other sports, like basketball, handball and rugby are also included.

Movement Asymmetries: From Their Molecular Origin to the Analysis of Movement Asymmetries in Athletes

“…Such situations often occur in team sports, such as football or hockey, where the player has a certain position on the playing field that determines the focus of his attention. In sports, where attention is distributed unevenly in different directions, specialists recommend athletes pass special cognitive tests to check and improve their reaction time [22,23]. Another important factor determining an athlete's susceptibility to injury may be the rules of the sport in question.…”

“…Another aspect to consider is that there may also be perception-driven movement asymmetries caused by asymmetries in visual, audio, or other senses. For example, athletes whose attention is unevenly distributed in different directions are more likely to also have reduced reaction and movement asymmetries in certain directions, and as a result, will be more prone to injury [22,23]. In this paper, we explore the current knowledge on the molecular basis of the movement asymmetries and the role of movement asymmetries in sport in order to define the line between positive and negative aspects related to the asymmetries and find out how the biomechanical and biological processes in an athlete's organism are connected to each other.…”

Kualitas Tidur Buruk Memperlambat Waktu Reaksi Visual pada Mahasiswa Program Studi Sarjana Fisioterapi Fakultas Kedokteran Universitas Udayana

“…Penelitian yang dilakukan di Indonesia mengukur waktu ©2023, JEKK, All Right Reserved reaksi hanya dengan satu jenis percobaan saja yaitu SRT 14,15 Variabel independen yang diukur adalah kualitas tidur menggunakan kuesioner Pittsburgh Sleep Quality Index (PSQI). Pengisian kuesioner PSQI dilakukan secara daring melalui format google form, hasil diinterpretasikan oleh peneliti dalam skor baik (0-5) dan skor buruk (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21). Kuesioner PSQI berbahasa Indonesia yang digunakan dalam penelitian ini sudah pernah diuji dan didapatkan hasil memenuhi taraf signifikansi dengan nilai korelasi r = 0,487-0,778 (nilai r tabel > 0,444) dan reliabel dengan nilai alpha cronbach 0,841 16 .…”

“…Berdasarkan hasil penelitian, skor waktu reaksi subjek sangat beragam. Rata-rata skor SRT adalah 296,13 milidetik dan rata-rata skor CRT adalah 409,8 milidetik, skor SRT termasuk dalam katagori baik dan skor CRT termasuk normal 20 . Skor CRT lebih besar dibandingkan dengan SRT disebabkan oleh perbedaan waktu dalam memproses informasi.…”
