Abstract

Data on resting heart rates, pre-exercise heart rates, the anticipatory rises before exercise, the influence of speed of work and recovery heart rates have been presented. Some observations on differences in the heart rate response on slow and fast working days are also recorded. In conformity with other workers, a linear relationship between heart rate and working speed within the range of 400-800 metre/min was observed. When the speed of work was between 400-800 metre/min, horses with resting ECG's classed as abnormal had significantly higher heart rates than those regarded as normal. It was also observed that the abnormal animals showed lower heart rates than a small number classed as borderline. The significance of these findings is discussed and the need for further work indicated.

摘要

已呈现静息心率、运动前心率、运动前预期升高心率、工作速度的影响以及恢复心率的数据。还记录了关于工作日快慢不同时心率反应差异的一些观察结果。与其他研究者一致，在400 - 800米/分钟范围内观察到心率与工作速度之间呈线性关系。当工作速度在400 - 800米/分钟之间时，静息心电图被归类为异常的马匹心率显著高于被视为正常的马匹。还观察到异常动物的心率低于少数被归类为临界状态的动物。讨论了这些发现的意义，并指出了进一步研究的必要性。
