Brachial systolic BP ( bSBP ) and aortic systolic BP ( aSBP ) , AP , AIx , AIx adjusted to 75 beats/min ( AIx75 ) , reflection time ( Tr ) , first ( P1 ) and second systolic peak ( P2 ; wave reflection magnitude ) , heart rate ( HR ) , and systolic time index ( STI ; myocardial oxygen demand ) at baseline and during CPT and magnitude of the response from baseline to CPT were evaluated in 13 individuals ( 10 women ; 571 year ; bSBP 1515 mm Hg ) .
