Key result
Endurance trained men demonstrated significantly faster oxygen uptake kinetics compared to inactive men regardless of age, indicating that fitness level and not aging per se determines the VO2 kinetics response.
Why the study?
Does fitness level rather than age determine the oxygen uptake kinetics response in healthy men?
Cross-Sectional (n=57)
No

p-value: p=<0.05
Fitness level, rather than aging itself, is the primary determinant of oxygen uptake kinetics and vascular reperfusion responses during exercise.
No takes yet. Share an insight, caveat, or question.
Fitness level was associated with faster VO2 kinetics independent of age; hypothesis-generating for interventional trials on training effects.
George et al. (2018) conducted a cross-sectional in Healthy aging and fitness (n=57). Endurance training / High fitness level vs. Inactive lifestyle was evaluated on Time constant of VO2 (τ VO2) (p=<0.05). Endurance trained men demonstrated significantly faster oxygen uptake kinetics compared to inactive men regardless of age, indicating that fitness level and not aging per se determines the VO2 kinetics response.
