Abstract
Purpose
The purpose of this study was to investigate the contribution of aerobic and anaerobic energy release on cycling performance in 10 to 180 s.
Methods
18 male cyclists from recreational- to elite level participated in this cross-sectional study. The cyclists were tested in oxygen cost of cycling (C), peak oxygen uptake (VO2peak), maximal sprint power (MSP), and five short time trials (TT): 10 s (10TT), 30 s (30TT), 60 s (60TT), 120 s (120TT) and 180 s (180TT). In all time trials, VO2, maximal accumulated oxygen deficit (MAOD) and blood lactate concentration ([La−]b) were measured.
Results
On average, there was a 50–50% distribution of anaerobic and aerobic energy release at 73 s and at 180TT the distribution was 71% aerobic and 29% anaerobic. When performance was expressed in absolute watt values, strong correlations were found between 180TT and MSP (r = 0.85, p
