Introduction

This study aimed to assess the extent and reproducibility of time to exhaustion (time limit) to maximal aerobic speed (MAS), which seeks minimum speed V ? O2 termmax.next previous term relationships between time limit at VMA and other criteria of aerobic fitness were also examined. Twelve riders selected to the championships of France half-marathon (<1 h 14 min) completed the test for determining the time limit for VMA treadmill. Eight of them repeated the same test 1 week apart. No significant differences were detected (the threshold a = 0.05) between the measured time limit between the first and second week respectively 6 min 44 sec (± 1 min 41 s) and 6 min 43 s (± 1 min 53 sec) but the coefficients of variation (CV) were equal to 26 and 28%. The standard deviation of differences between the two paired series is 57 seconds, or 14% of the average time limit. Moreover, the value of time limit to VMA was not significantly correlated with other performance parameters on long-distance races such as: ? V O2 termmaxnext previous term (r = 0.17, CV = 5.25% ), maximal aerobic speed (r = 0.32, CV = 4.4%), running economy (r = 0.38, CV = 7.2%) and "endurance index (r = 0.34, CV = 37.9%) (Perronet et al, 1987). However the time limit for VMA is correlated with anaerobic threshold expressed as a fraction (%) of V ? O2 termmaxnext previous term corresponding to the beginning of accumulation of lactate as a function of running speed around 3-5 mmol 1-1 according to the protocol and Aunola Rusko (1984) (r = 0.58, CV = 5.9%) and fraction of VMA supported on a half marathon (r = 0.62, CV = 5.8%) ( n = 12). If no significant difference was calculated between the two paired values tlim obtained 1 week apart, the standard deviation of their difference is taken into account as to conclude with a reproducibility of this measure in different populations studied. However the product of the maximum aerobic speed and limit his time: the distance limit can be a VMA performance index that takes into account both dimensions of intensity and duration to VMA.

Summary

This study Focus on the measurement and reproducibility of running time to exhaustion at V ? O2 termmaxnext previous term at maximum aerobic speed (MAS). The running velocity at maximal oxygen uptake, and The Relationship Between running time to exhaustion at 100% V ? O2 termmaxnext previous term and Other Bioenergetic Characteristics Examined are aussi. Twelve elite male long distance runners sub 29.5 years old (± 3.4) Completed a time limit at MAS is treadmill and 8 of Them prepend The Test One Week Later. Maximum aerobic speed WAS runnig Defined As The velocity at maximal oxygen uptake Which Occurred. To detemine The running time to exhaustion at maximal aerobic speed, The Runners Performed a warmup of 20 minutes duration run at 60% of MAS ...
