 Biometric variables, maximum aerobic capacity, and blood iron markers in athletes (n  =  65) grouped by HFE genotypes

wt/wtC282Y/wtH63D/wtC282Y/H63DH63D/H63DNormal ranges
Values are mean (SD). No significant differences in any of the variables (p>0.05) were detected among the athlete subgroups.
wt/wt, Wild-types; C282Y/wt, heterozygotes for the C282Y mutation; H63D/wt, heretozygotes for the H63D mutation; C282Y/H63D, compound heterozygotes; H63D/H63D, homozygotes for the H63D mutation; Vo2max, maximum aerobic capacity; Fe, iron; TSI, transferrin saturation index.
