Characteristics of the three phenotypes.

Parameter	Age (years)	Body mass (kg)
Endurance athlete (n = 30)	30.1 ± 5.7	64.5 ± 6.0
Power athlete (n = 17)	25.4 ± 10.1	88.6 ± 25.2
Non-athlete (n = 63)	29.5 ± 9.3	76.5 ± 12.8
p-value (3 phenotypes)	0.147	0.001
p-value (Endurance vs. Power)	0.455	< 0.001

Mean ± standard deviation of age and body mass of the studied endurance and power athletes, and non-athletes. Statistical analysis was conducted with univariate ANOVA with post hoc test of least significant difference.
