Evaluation of the Cardiorespiratory Endurance of Jeju Crossbred Horses according to Exercise Intensity

The present study was conducted to measure the cardiorespiratory endurance of Jeju crossbred horses according to hill tests and exercise intensity, thereby providing foundational data for evaluation of running capability of horses. The nine Jeju crossbred horses were subjected to the hill test with an inclination of around $30^{\circ}$ and six out of nine horses were used to measure the cardiorespiratory endurance according to three different exercise intensities (moderate, heavy, and very heavy). The running time for the hill test was 205 sec on average, while high deviation was observed between horses from 167 to 258 sec. In addition, the running time for the hill test was highly correlated with moderate exercise. While no significant difference in average heart rate was found between exercise intensities, a trend of large variation was found in the average heart rate between horses. The heart rate recovery was highly correlated with heavy exercise and very heavy exercise. The results showed that no significant difference in average heart rate was found among three exercise intensities, but there are large individual variations among horses.

제주산마의 운동강도별 심폐지구력 측정

본 연구는 제주산마의 hill test 및 운동 강도별 심폐지구력 측정으로 승용능력 평가를 위한 기초 자료로 활용하기 위해 수행하였다. 분석에 이용된 제주산마 9두는 경사도 30도 내외의 경사로 800 m를 주행하는 hill test를 실시하였으며, 이 중 6 두는 운동 강도별(moderate, heavy, very heavy) 심폐지구력을 측정하였다. Hill test 주행시간은 평균 205 초였으며, 개체간 편차는 큰 것으로 확인 되었고, moderate exercise와 높은 상관관계를 보였다. 운동 강도별 평균 심박수는 유의적인 차이가 없었으나, 개체간 평균 심박수는 차이가 큰 것으로 나타났다. 회복 심박수는 heavy exercise와 very heavy exercise에서 높은 상관관계를 확인할 수 있었다. 본 실험결과, 운동 강도별 평균 심박수 차이는 확인 할 수 없었으나, 개체간의 차이는 큰 것으로 확인되었다.
