Millet, G. P., Millet, G. Y., Hofmann, M. D., & Candau, R. B., (2000). Alterations in running economy and mechanics after maximal cycling in triathletes: Influence of performance level. International Journal of Sports Medicine, 21, 127-132.

Elite (N = 8) and intermediate (N = 18) middle-level triathletes completed two 7-min treadmill runs at a sustained velocity that could be achieved after cycling and without being preceded by cycling. The energy cost of running was determined in the last minute of each exercise.

The running of elite triathletes was less affected by cycling than that evidenced in the middle level performers. The mechanical cost of running was more efficient in elite than middle-level athletes. Elite athletes decreased the cost of braking and reduced vertical displacement in running technique, suggesting a better leg stiffness regulation than the lesser performers.

Implication. Elite triathletes run more efficiently after cycling than do middle-level triathletes. Running form improvement could be an avenue for elevating the standard of performance of middle-level triathletes.
