Data are means ± SE. P value was set at less than .05 significance level. Of the 61 persons with complete data on genotype, and glucose and insulin indices at baseline, 55 completed the intervention and final testing. ṾO2max (L/min) and ṾO2max (mL/kg per minute) indicate absolute and relative maximal oxygen consumption, respectively.
a
Statistically significant between genotype comparison.
b
Change within genotype groups.
