Design outcomes

Primary

MeasureTime frame
Change in heart rate from resting state (sitting) before exercise to peak state

Secondary

MeasureTime frame
Peak heart rate during exercise load,Change in the rate-pressure product (heart rate multiplied by systolic blood pressure) from pre-exercise rest to peak exercise,Resting heart rate in the supine position,Change in heart rate during head-up tilt load, Change in the rate-pressure product (heart rate multiplied by systolic blood pressure) from pre-tilt to near the end of the tilt load, Plasma norepinephrine concentration at rest and at the end of exercise during bicycle ergometer exercise load
