The effect of 3 weeks mountaineering training on the cardio-pulmonary response to submaximal exercise was studied on 7 women mountaineers. Exercise of 650 kg m/m to 700 kg m/m was given on a treadmill at a gradient of 20% and speed of 3.22 km/h. The physical conditioning effect imparted by the mountaineering training and altitude exposure was reflected in their response to exercise after training. The exercise and recovery O2 uptake and ventilation was significantly reduced after mountaineering. The recovery heart rate after exercise was significantly reduced. The improvement in the mechanical efficiency of mountain climbing with load after the mountaineering and the changes in the anaerobic component involved in the exercise may be the causative factor for the observed changes in the exercise and recovery O2 uptake, ventilation and recovery heart rate.
