Table 5. Characteristics of male and female athletes and athletes with, or without the Asp allele.

		Resting right ventricular stroke volume index (RVSVi, ml/m2)	Right ventricular mass index (RVMi g/m2)
Gender	Men	70.7±9.5 ‡	32.5±4.6 ‡
	Women	61.5±9.2	23.5±5.4
NOS3	Glu/Glu	64.3±9.8	27.4±6.0
	Asp carrier	71.1±9.6 #	31.7±5.5 #

In this age matched population of elite athletes with a similar social and ethnic background linear regression analysis revealed that both male gender and the presence of the Asp allele are independent predictors for higher resting right ventricular stroke volume index (RVSVi) and right ventricular mass index (RVMi) values.
