AB Running performance is a determinant factor for victory in Sprint and Olympic distancetriathlon. Previous cycling may impair running performance in triathlons, so brick training becomesan important part of training. Wearable technology that is used by triathletes can o er several metricsfor optimising training in real-time. The aim of this study was to analyse the e ect of previous cyclingon subsequent running performance in a field test, while using kinematics metrics and SmO2 providedby wearable devices that are potentially used by triathletes. Ten trained triathletes participated ina randomised crossover study, performing two trial sessions that were separated by seven days:the isolated run trial (IRT) and the bike-run trial (BRT). Running kinematics, physiological outcomes,and perceptual parameters were assessed before and after each running test. The running distancewas significantly lower in the BRT when compared to the IRT, with a decrease in stride length of0.1 m (p = 0.00) and higher %SmO2 (p = 0.00) in spite of the maximal intensity of exercise. No e ectswere reported in vertical oscillation, ground contact time, running cadence, and average heart rate.These findings may only be relevant to ‘moderate level’ triathletes, but not to ‘elite’ ones. Triathletesmight monitor their %SmO2 and stride length during brick training and then compare it with isolatedrunning to evaluate performance changes. Using wearable technology (near-infrared spectroscopy,accelerometry) for specific brick training may be a good option for triathletes.
