PurposeTo examine the reproducibility and validity of a new submaximal, ramped cycle ergometer testing methodology known as the Aerobic Adaptation Test (AAT), which attempts to detect changes in submaximal work capacity and minimize participant discomfort.Methods36 sedentary men (mean age= 48.1+/-10.2 yr [SD]) and 22 sedentary women (mean age= 51.9+/-10.2 yr [SD]) participated in the study. To test reproducibility, participants were tested twice with an average of 20 d between tests (+/-15 d). To test validity, participants were tested before and after a 6-month physical activity intervention, and outcomes were compared with standard measures of fitness (exercise time and oxygen consumption at 70% max heart rate). The main outcome variable of the AAT was work output (W) over a period of 3 min after reaching 70% maximal heart rate.ResultsThe average work output at 70% HRmax was highly reproducible, with a test-retest reliability of rho= 0.85 (P< 0.001). Average work output at 70% HRmax significantly increased after 6 months of physical activity intervention (87.8+/-32.9 W vs 95.5+/-37.9 W, P= 0.002), and changes in average work output at 70% HRmax correlated with changes in exercise time to elicit 70% HRmax (r= 0.87, P< 0.001) as well as changes in VO2 at 70% HRmax (r= 0.75, P< 0.001). Thus, the AAT appears to be a valid measure of submaximal work capacity.ConclusionsThe AAT is a reproducible and valid measure of submaximal work capacity that can serve as an effective means to evaluate physical activity interventions.
