Journal ArticleDOI
Effects of long duration exercise on cognitive function, blood glucose, and counterregulatory hormones in male cyclists.
Fabien Grego,Jean-Marc Vallier,Maya Collardeau,Stéphane Bermon,Patricia Ferrari,Mirande Candito,Pascale Bayer,Marie-Noëlle Magnié,Jeanick Brisswalter +8 more
TL;DR: A combined effect of arousal and central fatigue on electrocortical indices of cognitive function during acute physical exercise is suggested.
Journal ArticleDOI
Influence of exercise duration and hydration status on cognitive function during prolonged cycling exercise
TL;DR: Results provide some evidence for exercise-induced facilitation of cognitive function, however this positive effect disappears during prolonged exercise, as evidenced within this study by an increase in errors during the complex task and an alteration in perceptual response.
Journal ArticleDOI
Energetically optimal cadence vs. freely-chosen cadence during cycling: effect of exercise duration
Jeanick Brisswalter,Christophe Hausswirth,Darren M. Smith,Fabrice Vercruyssen,Jean-Marc Vallier +4 more
TL;DR: The results suggest that during prolonged exercise triathletes choose a cadence that is close to the energetically optimal cadence, a change of muscle fibre recruitment pattern with exercise duration and cadence would explain the shift in energetical optimal rate towards a higher pedal rate observed at the end of exercise.
Journal ArticleDOI
Increase in energy cost of running at the end of a triathlon
TL;DR: This outdoor study of running economy at the end of an Olympic distance triathlon demonstrated a decrease in running efficiency.
Journal ArticleDOI
Effect of two drafting modalities in cycling on running performance.
Christophe Hausswirth,Jean-Marc Vallier,Didier Lehénaff,Jeanick Brisswalter,Darren M. Smith,Grégoire P. Millet,Patrick Dréano +6 more
TL;DR: It is shown that drafting continuously behind a lead cyclist allows triathletes to save a significant amount of energy during the bike leg of a sprint triathlon and creates the conditions for an improved running performance compared with a situation where cycling is performed alternating the lead with another cyclist.
