Continuous heart rate recordings were obtained on elite American bi-athletes during competitions to provide a better understanding of the physiological demands of biathlon and the strategies used in approaching the shooting range. The findings demonstrate that the average age heart rate during skiing was approximately 90% of maximum heart rate. Heart rates decreased 10-12 bpm over a time period of approximately 50-60 sec during the approach to the firing line. At arrival to the firing line, heart rates were similar for prone and standing shooting averaging 85-87% of maximum heart rate. Mean minimum heart rates while at the firing line dropped to 61-73% of maximum heart rate and averaged approximately 20 bpm lower for prone shooting. The lower minimum heart rates during prone shooting were accounted for by the bi-athletes spending a longer time at the firing line and having a more rapid decrease in heart rate while in the prone position.
在美国优秀冬季两项运动员比赛期间进行了连续心率记录，以便更好地了解冬季两项的生理需求以及接近射击场时所采用的策略。研究结果表明，滑雪期间的平均年龄心率约为最大心率的90%。在接近射击线的大约50 - 60秒时间内，心率下降了10 - 12次/分钟。到达射击线时，卧射和立射的心率相似，平均为最大心率的85 - 87%。在射击线时的平均最低心率降至最大心率的61 - 73%，卧射时平均比立射低约20次/分钟。卧射时较低的最低心率是由于冬季两项运动员在射击线停留时间更长，且在卧姿时心率下降更快。
