Abstract/Description

This study assessed age-related changes in power and heart rate in 114 competitive male cyclists age 15–73 years. Participants completed a maximal Kingcycle™ ergometer test with maximal ramped minute power (RMPmax, W) recorded as the highest average power during any 60 s and maximal heart rate (HRmax, beats/min) as the highest value during the test. From age 15 to 29 (n = 38) RMPmax increased by 7.2 W/year (r = .53, SE 49 W, p < .05). From age 30 to 73 (n = 78) RMPmax declined by 2.4 W/year (r = –.49, SE 49 W, p < .05). Heart rate decreased across the full age range by 0.66 beats · min–1 · year–1 (r = –.75, SE 9 beats/min, p < .05). Age accounted for only 25% of the variance in RMPmax but 56% in HRmax. RMPmax was shown to peak at age 30, then decline with age, whereas HRmax declined across the full age range.
