Carbon Dioxide Expiration and Performance Fatigability Following Aerobic Exercise Training: A Longitudinal, Observational, Pilot Study.

ABSTRACT:

Purpose

This study examined the influence of aerobic exercise training (AET) on components of carbon dioxide expiration (VCO₂), cardiorespiratory function, and fatigability.

Methods

Twenty healthy adults completed peak cardiopulmonary exercise (CPX) and submaximal tests before and after a vigorous, 4-week AET regimen. Each test was followed by a 10-min recovery and endurance test at 70% of peak wattage attained during CPX. Fatigability was assessed using testing durations and power output. Respiratory buffering (excess VCO₂) and non-buffering (metabolic VCO₂) were calculated. Data were analyzed for significance (p<0.05) using regressions and paired t-tests.

Results

Significant improvements in all measures of fatigability were observed
