ClinConnect Summary

Fifty highly trained endurance runners (men and women, age: 18-35 years) will be recruited for this study. The first testing session will serve as a screening tool to determine subject eligibility. Following the first testing sessions subjects will be divided into EIAH or non-EIAH groups based on SaO2 at VO2max (EIAH \< 93%, non-EIAH \> 95%; Dempsey and Wagner criteria). Subjects with intermediate SaO2 (93-95% at VO2max) values will be included in the study for correlational analyses only.

All subjects will be advised orally, and in writing, as to the nature of the experiments and will giv...
