| Background: Exposure to high altitude causes significant stress in the functioning of cardiovascular and respiratory systems. Aim: The aim of this study was to investigate the changes in systolic and diastolic blood pressure (BP), heart rate (HR) and pulmonary volumes during the classic ascent of Damavand 5671 m peak. Materials and Methods: 14 healthy male climbers (age = 23.85±5.93 years, height = 175.5±5.91 cm, weight =71.35±8.20 kg) participated voluntarily in this study. BP, HR and lung volumes were measured in basic (2000 M), BC (3100 m) the first day, C1 (3650 m) the first day, BC (3100 m) the second day after the one-night stopover, C1 (3650 m) the second day, C2 (4100 m) the second day, C2 (4100 M) third day after the one-night stopover, C3 (5000 m) and, peak (5671 m). Data were compared by repeated measures test at the significant level of P≤0.05 and Bonferroni post hoc test. Results: The results of repeated measures analysis were significant for HR, systolic BP, diastolic BP and MVV (P<0.05), but not significant for FVC and FEV1 (P≥0.05). BP was high in the base camp and the first camp and gradually decreased. HR continued to increase significantly with increasing altitude. MVV increased with increasing altitude and is reduced after the one-night stopover in each height. Conclusion: It can be concluded that climbing with classic method increased the HR and decreased systolic and diastolic BP of climbers. It was able to induce adaptation in lung volumes of climbers. | ||
