Elite athletes in all sports—whether endurance, power, or skill—have similar efficiency in how their lungs manage carbon dioxide removal during intense exercise, indicating that ventilatory adaptation is not sport-specific.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A systematic review would determine whether the lack of difference in ventilatory efficiency is consistent across studies and whether it reflects universal adaptation in elite athletes.
A systematic review and meta-analysis of all studies reporting VE/VCO2 slope in elite athletes classified by sport category, pooling mean differences and assessing heterogeneity across training environments and ethnicities.
An RCT would determine whether training in different sports causes divergent or convergent changes in ventilatory efficiency over time.
A 2-year RCT assigning 200 healthy young adults to endurance, power, mixed, or skill training (12 hrs/week), measuring VE/VCO2 slope via CPET at baseline, 12, and 24 months, with ventilatory efficiency as the primary outcome.
A prospective cohort would determine whether ventilatory efficiency converges toward a similar level as athletes reach elite status, regardless of sport type.
A 10-year prospective cohort tracking 800 adolescent athletes (aged 12–16) assigned to different sports, with annual CPET assessments of VE/VCO2 slope to determine if it stabilizes similarly across categories by elite status.
A larger cross-sectional study could validate the lack of difference in ventilatory efficiency across diverse populations and training environments.
A multicenter cross-sectional study measuring VE/VCO2 slope in 3000 elite athletes across 10 countries, stratified by sport category, with controls for age, sex, and training volume.
Case series of athletes switching sports could show whether ventilatory efficiency changes in response to altered training demands.
A case series of 40 elite athletes who transitioned from endurance to skill sports (or vice versa), with serial CPET assessments of VE/VCO2 slope before and after transition over 1–3 years.
