ABSTRACT

Objective: The aim of this study is to exam the effects of exercise modes on the systolic blood pressure and rate-pressure product during a gradually increasing exercise load from low to high intensity.

Methods: Fifteen apparently healthy men aged 19 to 23 performed the graded exercise tests on cycle ergometer (CE) and treadmill (TM). During the low-to-maximal exercises, oxygen uptake (VO2), heart rate (HR), systolic blood pressure (SBP) and rate-pressure product were measured.

Results: CE had a significantly lower maximum VO2 than TM (CE vs. TM: 48.51±1.30 vs. 55.4±1.19 mL/kg/min; p<0.001). However, CE showed a higher maximum SBP (SBPmax) at the all-out exercise load than TM (CE vs. TM: 170±2.4 vs. 154±1.7 mmHg; p<0.001). During the low-to-maximal intensity increment, the slope of the HR with VO2 was the same as VO2 increased in times of the graded exercise test of CE and TM (CE vs. TM: 2.542±0.100 vs. 2.506±0.087; p=0.26). The slope of increase on SBP accompanied by VO2 increase was significantly higher in CE than in TM (CE vs. TM: 1.669±0.117 vs. 1.179±0.063; p<0.001).

Conclusion: The SBP response is stronger in CE than in TM during the graded exercise test. Therefore, there is a possibility that CE could induce a greater burden on workloads to cardiovascular system in humans than TM.

Mentions: From the graded exercise tests on the CE and TM reaching from low intensity to maximal intensity, patterns of responses of HR, SBP, and RPP for gradually increasing load VO2 are as in (Fig. 2). HR, SBP, and RPP proportionally increased as VO2 increased, but SBP and RPP of CE were higher than TM, except that HRs of CE and TM maintained the same level with each other in terms of the width and slope for the increase.
