The purpose of this study was to investigate correlation analyses and relative contributions between 4km individual time trial, response variable that represent the cycling capacity of endurance performance and explanatory variables in elite cyclists. These variables was assessed in 15 male elite cyclists(age 20.3±1.17 years, height 176.3±4.09 cm, weight 71.2±4.95kg, career 6.53±years).
Independent variables were composed of 20 variables(VO2max, VT, aerobic maximum power, anaerobic maximum power, anaerobic average power, ratio of click position, foot average angle for 1min., maximum flexion-muscle power, maximum extension-muscle power, ratio of maximum flexion-muscle power to extension, flexion-muscle endurance, extension-muscle endurance, ratio of maximum flexion-muscle endurance to extension, flexion-muscle average power, extension-muscle average power, ratio of flexion-muscle average power to extension) from 5 regions(aerobic, anaerobic, kinematic, isokinetic region, and physical constitution) and response variable, record of 4km individual time trial was measured under field test conditions.
Aerobic data were collected with Excalibur(Lode com.) and Quark b2(Cosmed com.) during an incremental exercise test and anaerobic data were collected with Excalibur(Lode com.) during Wingate test designed by Bar-Or. Kinematic data were captured with Qualisys System(Sweden), anthropometric data were measured with body measuring rulers by an authorized expert(ISAK), and Isokinetic muscle power were measured with Norm 3(Humac com, USA). The conclusions of this study were as follows:
First, The correlations of coefficient between VO2max(maximal oxygen uptake) and anaerobic threshold were not statistically significant. But between the records of 4km individual time trial and the anaerobic average power, aerobic maximal power that means mechanical energy, and the average extensor power were statistically significant(negative correlation coefficients).
Second. the effects of VO2max affecting a capacity of endurance exercise somewhat were conceded, but VO2max was not an indicator which evaluated the records of 4km individual time trial
Third, the correlation coefficients between body weights affecting negative effect and records of 4km were statistically significant(negative correlation coefficients).
Fourth, the relative contributions affecting the records of 4km individual time trial were the anaerobic average power and the average extensor power in order.
Cycling is a process which transmit human energy to bicycle, and has characteristics depended on the muscle power using high gear-rate and a rapid pedaling speed. Therefore, cyclists must have two factors to play the game well. As for the records of 4km individual time trial, because anaerobic average power has both a muscle a power and a speed, anaerobic average power was a greater relative contribution of the two.
If anaerobic average power was enhanced, the records of 4km individual time trial could enhance. Thus, power was a good tool to estimate endurance performance in 4km individual time trial. In future, to improve the records of that it is necessary that anaerobic average power should be improved above all, and we suggest that anaerobic average power was regarded as main training factors to raise endurance performance.
