PURPOSE The purpose of this study was to develop the estimating equations for 4 types of Wingate Anaerobic test setting. METHODS 80 male elite athletes performed 4 trials of the Wingate Anaerobic test by each type. Subjects were conducted the retest one week later. Data collected from the Wingate Anaerobic test included mean power, peak power, and power drop for 30s were measured. Coefficient of correlation was used for validity of type 1(DOS version) and the other types(ver. 2.24, 3.3.0, and 3.2.1). Pearson’s correlation coefficient was used to examine the reliability of test and retest. Simple regression analysis was used for calculating the estimating equation. RESULTS There was significant correlation for absolute value(Watt, p<.01) and relative value(Watt/kg, p<.01) of mean power, absolute value(W, p<.01), relative value(Watt/kg, p<.05), and power drop rate(%, p<.01). Test and retest reliability was excellent for all test variables(p<.01). CONCLUSIONS From the all results, the estimating equation was calculated to convert all outputs from each type to the other types of the Wingate Anaerobic test setting. These findings suggest that the estimating equations are compatiable to 4 types of Wingate Anaerobic test setting.
The purpose of this study was to investigate basal physical fitness and smash speed of elite national badminton players. To perform this study, total forty six korea national badminton player were participated : twenty two male players(age : 20.90±2.24years, height : 179.30±5.40cm, weight : 73.80±7.12kg, career : 11.27±1.88years) and twenty four female players(age : 19.45±1.95years, height : 167.83±4.36cm, weight : 61.39±3.60kg, career : 9.50±2.47years). Each subjects performed the 6 basal physical fitness trials : agility, muscular endurance, muscular strength, flexibility, balance and cardiorespiratory endurance. And the speed of badminton smash were analysis by using radar gun when players were standing smash success. To determine the difference between two groups, independent samples test was used. As a result, we found that there was a large difference male players and female players in basal physical fitness and smash speed. First, male players were significantly strong in agility(side step 10%), muscular endurance(repetitional jump 12%), muscular strength(left grasping power 3%, right grasping power 31%) and cardiorespiratory endurance(20m suttle run 31%). On the other hand, female players were relatively strong in flexibility(sit and reach 27%) and balance(standing on one leg with eyes closed 51%). Second, maximum smash speed show that male players were about 57km/h(24%) faster than female players(male : 247.72km/h, female : 190.37km/h). Based on the findings, we shall be applicable training program to improve flexibility, balance of male athletes and agility, muscular endurance, muscular strength, and cardiorespiratory endurance of female athletes. our results will be appliable to improve the athletic performances of national badminton players by the coaches in the future.
