Effects of Weekly Climbs of Mt. Fuji on the Aerobic Capacity of a Normal Subject
The purpose of the present study was to investigate the effects of weekly climbing (>3500m) over a 4-week period. The mountain used was Mt. Fuji, which has a summit of 3776m and is the highest peak in Japan. The subject was a normal healthy male (age 40yrs ; height 173cm ; weight 62kg ; BMI 20.7), who had never climbed Mt. Fuji and lived at sea level. He reported a history of physical exercise a few times every week. He took climbing four times, about 3 hours to climb (2400 to 3776m) and 2 hours to descend (3776 to 2400m) Mt. Fuji. Treadmill running tests were conducted before the 1st and after the 4th climb. We measured maximal oxygen uptake (VO_<2 max>), maximal ventilation (VE_<max>), ventilation threshold-speed (VT-speed) and heart rate (HR) for treadmill running tests. In addition, VO_2, VE, HR, SpO_2 and rating of perceived exertion (RPE) were measured for the 1st and 4th climb. Treadmill running tests revealed significant improvements to VO_<2 max> (55.11 vs. 60.73mL/min/kg), VE_<max> (108.1 vs. 123.5L/min), VT-speeds (180 vs. 220m/min) and HR (decreased to about 10 beats/min every running speeds). No change was observed in exhaustion speed (300m/min). Measurements for the 1st and 4th climbs demonstrated clear improvements to VO_2, VE, RPE and SpO_2. The improvements to aerobic potential after the four weekly climbs may be attributable to altitude acclimatization. It is expected that running performance in non-expert runner was improved with weekly mountain climbing (>3500m) for four weeks.
