The purpose of this study was analysis of physical function affected by the climb down of group climber. The subjects was 16 healthy male and female college students in 400 climbers of 18 to 21 and they were divided into two groups : Group A (take 10 minute rest during climb down), Group B (take no rest during climb down), The influence of physical function inferred to the percent of HR max (%HRmax) from heart rate during climb up, rest, mountaintop and climb down. The following results were obtained : 1) The mean of % HR max at climb down of two groups indicated of the numerical value about 60 % of HR max. 2) The % HR max of each subject during climb down was 40 % through 80 % of HR max. 3) Therefore, the most important thing during climb down for group climber continued to keep the same walking speed during climb down. Becouse the difference of physical function was affected by walk distance and the condition of natural environment. The most important thing on the walking speed during climb down was to walk at the rate of about 30 m per minute. The best condition of % HR max during climb down is throught to keep numerical value about 60 % of HR max on the work load during climb down.
