对手球运动员在训练中的乳酸无氧代谢进行了研究。七名年龄在18-21岁之间的球员，属于乙级联赛俱乐部，参加了这项研究。在实验室中，用进行性最大功循环试验确定VO 2 max和血乳酸积累（OBLA）的开始。在球场上，视频记录，心脏遥测和直肠温度测量在上半场的比赛中被用来量化的努力。在第5、10、15、20和30分钟的比赛和10分钟的休息期后，使用永久佩戴的静脉导管抽血进行乳酸盐测量。结果证实了早期的观察显示，需要一个优秀的最大有氧功率和能力的手球。然而，观察到的最大乳酸盐水平（4- 9mmol. L-1）高于仅在游戏结束时抽取的样品所预期的那些。这些发现表明，球员必须接受训练，以容忍高乳酸水平，以保持他们的最大效率在整个游戏。最后，乳酸的产生随着运动员的努力和OBLA的增加而增加。
The authors investigated lactic anaerobic metabolism in handball players during practice games. Seven players aged 18-21, belonging to second division league clubs, took part in the study. In the laboratory, .ovrhdot.VO2 max and the onset of blood lactate accumulation (OBLA) were determined with progressive maximal ergocycle tests. On the field, video recordings, cardiotelemetry, and rectal temperature measurements made during the first half of the game were used to quantify exertion. An intravenous catheter worn permanently was used to draw blood for lactate measurements at the 5th, 10th, 15th, 20th, and 30th min of play and after a 10-min rest period. The results confirmed earlier observations showing the need for an excellent maximal aerobic power and capacity in handballers. However, the maximal lactate levels observed (4-9 mmol .cntdot. l-1) were above those that could be expected from samples drawn only at the end of play. These findings indicate that players must be trained to tolerate high lactate levels to preserve their maximal efficiency throughout the game. Finally, lactate production increased with player exertion and with increasing OBLA.
