Abstract/OtherAbstract:
To determine the effects of anaerobic metabolism on blood pressure (BP), 25 subjects were studied for BP response to graded and continuous leg-crank ergometry under both aerobic and anaerobic conditions. Measurements obtained during exercise also included ventilatory equivalents for oxygen and carbon dioxide to determine anaerobic threshold. Systolic and diastolic BP responses to exercise before anaerobic threshold were compared with responses after anaerobic threshold by linear regression analyses. The systolic BP response to graded exercise was significantly accelerated (p less than 0.01) after anaerobic threshold, demonstrating a nonlinear response to proportionately graded exercise demand. Comparison of the slopes or rates of change in diastolic BP before and after anaerobic threshold also indicated a significant difference (p less than 0.01) under these 2 different metabolic conditions. It is concluded that in contrast to the linear response of BP under conditions of aerobic metabolism, BP responds nonlinearly during anaerobic metabolism.
