Key result
Elite triathletes exhibited specific pulmonary responses to a cycle-run succession, including increased residual volume and functional residual capacity (P<0.05), compared to competitive triathletes.

Does performance level affect pulmonary responses during a cycle-run succession in male triathletes?
p-value: p=<.05
Elite triathletes exhibit different pulmonary adaptations and responses to sequential cycle-run exercise compared to competitive triathletes.
Performance level may influence pulmonary responses to cycle-run exercise; leaves open whether differences affect outcomes or warrant training changes.
OBJECTIVES: The purpose of this study was to determine the effect of performance level on the pulmonary responses in triathletes during the cycle-run succession. METHODS: Eight regionally and nationally ranked (Competitive) and six internationally ranked (Elite) male triathletes underwent 30 min of cycling followed by 20 min of running (C-R) and 30 min of control cycling (C). Before and 10 min after each trial, the triathletes underwent lung function testing. Ventilatory data were collected every minute using an automated breath-by-breath system. RESULTS: The results showed that (a) cycling induced a significant increase in residual volume and functional residual capacity in the Elite group (P <.05); (b) although cycling induced a significant decrease in DLCO in both groups, this decrease persisted at the end of the cycle-run exercise in the Competitive group only (P <.05); and (c) the rise in breathing frequency was significantly greater in the Competitive triathletes during the first 8 min of the subsequent run (P <.04). CONCLUSIONS: We conclude that the internationally ranked--or elite-performance--triathletes may have developed specific responses to the cycle-run succession.

Hüe et al. (2001) conducted an observational in Healthy triathletes (n=14). Elite performance level vs. Competitive performance level was evaluated on Pulmonary responses (residual volume, functional residual capacity, DLCO, breathing frequency) (p=<.05). Elite triathletes exhibited specific pulmonary responses to a cycle-run succession, including increased residual volume and functional residual capacity (P<0.05), compared to competitive triathletes.
