HT, heart rate; RER, respiratory exchange ratio; VO2, oxygen uptake; EE, energy expenditure; EEsteady_state, estimated energy expenditure over one hour based on the EE during the last minute of each intensity stage; EE4min, exact energy expenditure during each of the 4-min stages; EPOC, excess post exercise oxygen consumption;
*, different to all other exercise modes; NS, not significant.
