Heart rate (fc) and post-competition blood lactate concentration ([La+]) were studied in seven male professional National Hunt jockeys over 30 races. The fc response for individual races followed a similar pattern for all subjects. The mean peak fc recorded during competition was 184 beats.min-1 (range 162-198 beats.min-1) with average fc during the races ranging from 136 to 188 beats.min-1. During consecutive races the recovery fc did not return to resting values. The mean [La+] was 7.1 mmol.l-1 (range 3.5-15.0 mmol.l-1). The conclusions of this study suggest that riding in National Hunt races is a physically demanding occupation. The muscular activity in this profession requires a high metabolic drive and produces a significant cardiorespiratory response.
对7名男性职业障碍赛马骑师在30场比赛中的心率（fc）和赛后血乳酸浓度（[La+]）进行了研究。所有受试者在各场比赛中的fc反应模式相似。比赛期间记录的平均最高fc为184次/分钟（范围为162 - 198次/分钟），比赛期间的平均fc范围为136至188次/分钟。在连续比赛中，恢复fc未恢复到静息值。平均[La+]为7.1毫摩尔/升（范围为3.5 - 15.0毫摩尔/升）。本研究的结论表明，参加障碍赛马比赛是一项对体力要求很高的职业。该职业中的肌肉活动需要高代谢驱动力，并产生显著的心肺反应。
