The purpose of this study is the development of leg power, reaction time, and force device based on affordable platform with android in badminton. The method used the Research & Development (R&D) approach. 30 samples were involved in testing the prototype device instrument. The materials used were Loadcells TAL220 sensor, Arduino Nano Microcontroler and Bluetooth HC-05. The results showed that the correlation coefficient values for the measurement of the leg power, reaction and force variables each had values r = 0.904, r = 0.891 and r = 0.687, while the reliability were leg power r = 0.832, reaction r = 0.841, and force r = 0.972 using a significance level of 0.05.The conclusion from these data shows that the prototype of this device instrument has a high value of validity and reliability after compared with standard commercial tool so that this prototype is very feasible to be used especially in badminton
One of determinant factors of an athlete’s high achievement is a good physical condition. The cardiorespiratory endurance becomes one of the vital physical condition components in sport. The measurement of cardiorespiratory endurance for the aerobic capacity can be conducted by measuring the maximum oxygen consumption (VO2max). The measuring method of VO2max value can employ the direct and indirect measurement approaches. The purpose of this study was to analyze the VO2max with the direct and indirect measurement in badminton, rowing, and cycling by considering the different mechanism of the dominant movement of each other. The method was a descriptive quantitative study with comparative approach. The sample of this study were male athletes in rowing, badminton, and cycling involving 24 athletes. Each sport consisted of eight athletes as the samples.
Background. The badminton forehand overhead jump smash is one of the high speed and powerful motions among various racket sports. Objectives. The purpose of this study is to analyze the effect of fatigue on the kinematic variable movement changes during overhead jump smash in badminton. Methods. This study is descriptive quantitative research with the pre-test and post-test design methods used to obtain data from 15 male badminton players, aged 19.4±1.6 years, height 1.73 ± 0.12 m, and weight 60.8 ± 3.7 kg. The study used three high-resolution handy-cams, motion software Frame DIAZ IV, and 14 point manual markers to analyze body segments’ movement when carrying out a jump smash. Furthermore, an ergo treadmill was used to test the players’ level by running. Results. The results showed that the shuttlecock velocity was faster during pre-fatigue (188 km/h) than under the condition (145 km/h).
