Table 2 GH1 A/T polymorphism genotype and allele frequencies in the South African Ironman triathlete (Fast Triath) and control (Con) groups.

	Fast Triath (n  =  169)	Con (n  =  155)
AA genotype	36 (21.3)*	31 (20.0)*
TA genotype	84 (49.7)*	74 (47.7)*
TT genotype	49 (29.0)*	50 (32.3)*
A allele	156 (46.2)†	136 (43.9)†
T allele	174 (53.8)†	174 (56.1)†

Values are expressed as the number of subjects or alleles, with the percentage in parentheses.

*Fast Triath v Con genotype distribution, Pearsons χ²  =  0.412 and p  =  0.814.

†Fast Triath v Con allele distribution, χ²  =  0.254 and p  =  0.614.
