General mixed effects models revealed that the intervention group reduced pulse wave velocity by 9 % ( p = 0.05 ) ; Emv/Vp by 14 % ( p = 0.06 ) ; E to A ratio by 24 % ( p = 0.004 ) , E to Emv ratio by 8 % ( p = 0.05 ) , MLHFQ score by 66 % ( p = 0.003 ) and the depression score by 19 % ( p = 0.5 ) ; increased augmentation index by 29 % ; VTI by 4 % ( p = 0.05 ) , 6-minute-walk distance up to 13 % ( p = 0.05 ) , peak oxygen uptake by 28 % ( p = 0.001 ) and peak power by 25 % ( p = 0.005 ) .
