  • Significantly greater than in elite athletes and recreational athletes without LVH;

  • significantly greater than in individuals with HCM and recreational athletes;

  • significantly greater than in individuals with HCM.

  • legend ANOVA = analysis of variance; AT = anaerobic threshold; delta systolic BP = rise in systolic blood pressure from rest to peak exercise; BSA = body surface area; HCM = hypertrophic cardiomyopathy; HR = heart rate; LVH = left ventricular hypertrophy; LVWT = left ventricular wall thickness; O2 = oxygen pulse; pVO2 = peak oxygen consumption; RER = respiratory quotient.
