This study was carried out to investigate exercise load of visitors and physical condition of stairway in the trail of Keumsan located in Hallyo-Haesang National Park. Total trail length of Keumsan is 2,126m, and the number of step-trail section are 15, and the total length of step-trail section is 1,000.4m. Average gradient of step-trail was 20~40%. But the gradient and length were 45.7% and 268.5m in the section 11, and 58.4% and 188.6m in the section 12. The greatest gradient was 67.8% in the section 13. During the climbing in trail, heart rate were 104~184beats/min.. And in the step-trail section 11, 12, and 13, IHR, ELI, and %HRmax were 166.5%, 89.1%, 92.9%, and 167.4%, 89.6%, 93.2%, and 157.8%, 84.5%, 89.9%, respectively.

To investigate the heart rate changes under the influence of physical conditions on mountain trails, heart rates of 3 subjects were recorded on 9 routes in Kyeryongsan National Park and Odaesan National Park. Maximal heart rate during uphill walking recorded between 84% and 96% to individual maximal heart rate using ergometer, thus uphill walking on mountain trail was an exhaustive exercise. The ratio of maximal heart rate during downhill walking indicated between 78% and 93% to maximal heart rate during uphill walking. And gradient of trail influenced on heart rate, but width of trail didn't. The heart rate on wooden- or stony-step-trail were rapidly increased in comparison with the heart rates on soil-trails.
