To determine if there is any difference in ventilatory performance in individuals with craniofacial cephalometric landmarks associated with obstructive sleep apnoea during sub-maximal and maximal exertion in elite athletes. Twenty-seven, male, team-sport athletes, underwent facial cephalometric assessment and were graded into Class 1 (N = 14), Class 2 (N = 10) or Class 3 (N= 3) facial skeletal profiles. Posterior airway space (PAS), soft palate length (PNS-P) and hyoid to mandibular plane length (MP-H) were also measured. Each athlete then completed a graded exercise test (GTX) to exhaustion on a treadmill. Minute ventilation (L· Min-1) was measured during the GTX at intensities that equated to 10km.h-1, and subjective maximal effort.  A comparison of cephalometric landmarks and ventilation was made. No interpretable statistically significant results were found. There was no relationship between airway cephalometric parameters and ventilatory performance.
