Why the study?
Does genetic variance affect blood pressure and haemodynamic phenotypes at rest and during exercise in male twins?
Population
106 male twins (32 pairs monozygotic, 21 pairs dizygotic) aged 18 to 31 years
Comparison
Supine submaximal bicycle exercise vs Resting conditions
Design
Cross-sectional

Genetic effects predominate at rest but weaken during exercise; hypothesis-generating for heritability in dynamic BP assessment.
Does genetic variance affect blood pressure and haemodynamic phenotypes at rest and during exercise in male twins?
Genetic factors significantly influence resting blood pressure and hemodynamics, but their effect is diminished during submaximal exercise.
