UNASSIGNED: Impaired @entity410 ( @entity410 ) is a hallmark characteristic in @entity28 and lean sedentary young @entity1 . Peak @entity26 consumption (VO2peak) prediction from the six-minute step test (6MST) has not been established for sedentary females. It is recognized that lower-limb muscle strength and power play a key role during functional activities. The aim of this study was to investigate cardiorespiratory responses during the 6MST and CPX and to develop a predictive equation to estimate VO2peak in both lean and @entity28 subjects. Additionally we aim to investigate how muscle function impacts functional performance. Lean (LN = 13) and @entity28 (OB = 18) @entity1 , aged 20-45, underwent a CPX, two 6MSTs, and isokinetic and isometric knee extensor strength and power evaluations. Regression analysis assessed the ability to predict VO2peak from the 6MST, age and body mass index (BMI). @entity34256 and 6MST main outcomes were compared between LN and OB and correlated with strength and power variables. @entity410 , functional capacity, and muscle strength and power were lower in the OB compared to LN (<0.05). During the 6MST, LN and OB reached ~90% of predicted maximal heart rate and ~80% of the VO2peak obtained during CPX. BMI, age and number of step cycles (NSC) explained 83% of the total variance in VO2peak. Moderate to strong correlations between VO2peak at CPX and VO2peak at 6MST (r = 0.86), VO2peak at CPX and NSC (r = 0.80), as well as between VO2peak, NSC and muscle strength and power variables were found (p<0.05). These findings indicate the 6MST, BMI and age accurately predict VO2peak in both lean and @entity28 young sedentary @entity1 . Muscle strength and power were related to measures of aerobic and functional performance.
