Adolescents ( n = 31 ) with decreased % BF ( mean change [ range ] , -4.4 % [ -18.3 to -0.01 % ] ) after the intervention had significant increases in the mean large arterial elasticity index ( mean change [ 95 % CI ] , 5.1 [ 1.9 to 8.2 ] mL/mm Hg * 10 ; P = .003 ) and insulin sensitivity index ( 0.5 [ 0.1 to 0.9 ] ; P = .010 ) and a decrease in systemic vascular resistance ( -82 [ -129 to -35 ] dyne * s * cm ( -5 ) ; P = .001 ) .
