Methods：8 elite high school korfball player participated this research (age 17 ± 0.93 yrs、height 169.75 ± 8.41cm、weight 64.13 ± 7.0 kg、periods of playing 5.5 ± 2.27 yrs、VO2max：50.76 ± 2.5 ml/kg/min ). Competition HR was recorded by portable HR recorder (Polar S810) , and blood samples were collected by the finger tip method before, during and after the competitions. Results：Within the first 3 games of the competition, all player recorded higher mean HR from the first half of the game than the second (α<.05), and male player being higher than female players. Bla concentration before the games is lower than half time and after the game data (α<.05), but there were no differences between genders (α>.05). Conclusion：korfball provides sufficient exercise loads for athletes from all ages, korfball players should be trained according to competition demands which includes high tolerance of Bla and the exercise intensity must exeed 70% Hrmax, In order to gain maximal training effect, drills should be organized according to this specialty. Key words：competition, heart rate, blood lactate concentration
