Cardiovascular response
intensity-related increase
During the exercise period a significant intensity-related increase in HR and CO was evident (Tables The present results show that the HR and CO during exercise and during cumulative exercise and resting times was significantly higher at 75% intensity than at the two lower intensities (Table We recorded the blood pressure during exercise at 62.5% RM in follow-up examinations. The squats were done with one arm at a slowed repetition frequency. As doing the squats while measuring blood pressure was equivalent to the training sessions except for the lower speed, one can assume the assessed blood pressure values to be representative, with a tendency to higher valuesIn the post-exercise period SBP and DBP did not differ between intensities. This might relate to decreased vascular resistance (TPR) after strength exercise with higher intensity because of either higher flow-mediated and/or metabolic vasodilationStrength training does not seem to stimulate oxygen uptake substantially more than endurance trainingTo summarize: the cardiac parameters (unlike the pulmonary parameters due to pressurized breathing), reveal a more distinct intensity-dependent response during exercise. Significant increases in CO are evident during the post-exercise period, which is attributable to the lower blood pressure without load.
