摘要：

To test the hypothesis that the changes in hypoxic ventilatory response (HVR) of men and women mountaineers on induction to HA by trekking is not influenced by gender, isocapnic HVR as DeltaV(E)/DeltaSa(O2) was studied in eight men and eight women mountaineering trainees initially at 2100 m, then during 6 to 7 days of sojourn at 4350 m, and retested again on return to 2100 m. Results indicated that HVR at 2100 m increased significantly at 4350 In in both sexes, and the values reverted to baseline level within 4 to 5 days between leaving high altitude (4350 m) and restudy at 2100 m. No sex differences were observed at 2100- or at 4350-m altitude, indicating that men and women have a similar level of chemosensitive response as measured by HVR during induction to HA.
