Key result
Cycling and running yield similar VO2max but large AT HR errors limit training zone transferability.
Why the study?
Can physiological measurements obtained from cycling be applied to prescribe heart rate zone training for running in triathletes?
Cross-Sectional (n=16)
Can physiological measurements obtained from cycling be applied to prescribe heart rate zone training for running in triathletes?
Absolute Event Rate: 68.4% vs 69%
Triathletes should perform sport-specific testing to assess training zones for cycling and running, as heart rate zones are not directly transferable between the two modes.

May warrant sport-specific testing for HR zones in triathletes; challenges direct transferability of cycling data to running.
Carey et al. (2009) conducted a cross-sectional in experienced triathletes (n=16). Cycle ergometer testing vs. Treadmill testing was evaluated on VO2max (ml/kg/min). Physiological measurements like VO2max (68.4 vs 69.0 ml/kg/min) did not significantly differ between cycling and running, but a large total error in AT HR limits transferability of training zones.
