The study investigated physiological responses during 2-km walking at a certain intensity of a previously performed maximal exercise test where a moderate perceived exertion was reported. 20 seniors were examined by an incremental walking treadmill test to obtain VO2max. A submaximal 2-km walking test was applied one week later. The corresponding moderate perceived exertion (of 4, CR-10 scale) during the VO2max-test was applied to the 2-km treadmill test. Moderate exertion (mean RPE: 4±1) led to 76±8% of VO2max and 79±6% of HRmax. RPE values drifted with a significant time-effect (p=0.001, ηp=0.58) during the 2-km test from 3±0.7 to 4.6±0.8... . Total energy expenditure (EE) was 3.3±0.5 kcal/kg. No gender-differences in ventilatory, heart rate and EE data occurred. Brisk walking at moderate RPE between 3 and 5 would lead to a beneficial physiological response during endurance training and a weekly EE of nearly 1200 kcal when exercising 5 times per week for 30 minutes. |
