RESUMO
The purpose of this study was to explore the significance of AT nn the prediction and determination of endurance performance in 60 athletes, including long distance runners, marathoners and cyclists. 17 nonendurance athletes served as control group. Every subject performed an. incremental exercise test on Monark cycle ergometer. The work rate was increased in steps of 30W/min until the subject was unable to sustain the workrate. The Vo_2, Vco_2 and Mets werecontinually measured during and after test by MMC of Beckman company The test and retest of AT were made in 14 long distance runners in their one-year training cycle. On the basis of the results the prediction of the endurance performance was done before competition After competition the determination of endurance performance and positive rate for variables and correlation. coefficient to AT were summarized. All calculated performance: variables correlated the 1500m, and 10,000m with r=0.68 and r=0.80 respectively. In conclusion, the results of the study confirmed the high significance of AT in the prediction of endurance performance in athletes.
