Exercise physiologists have previously avoided using interval exercise training with the elderly due to concerns over increased heart rates (HRs) and respiratory stress that are generally constant during a steady-state cardiovascular exercise session. The purpose of this research was to examine the physiological responses in the elderly using two protocols, constant and interval intensity cycle exercises. The subjects completed two randomised 20-min exercise protocols on an electronically braked cycle ergometer, one at a constant 50% of VO2 max, and the second alternated intensity from 70% to 30% VO2 max in 1-min cycles. Physiological measures of VO2, HR, RER, and RPE were taken. The subjects reported similar RPE values for both protocols. The elderly subjects generated a 16% higher VO2 during interval training, when compared to a constant intensity exercise. The HR varied 12.1 beats·min-1 during the constant protocol compared to 22.6 beats·min-1 for the interval protocol. When coupled with the self-reported increased enjoyment, the interval protocol may be more beneficial for the elderly when used in a conditioning program.
