Summary

The phenotype based on the insertion/deletion (I/D) polymorphism of the human angiotensin converting enzyme (ACE) gene has been associated with individual training response. Briefly, intervention studies have demonstrated an 11-fold greater training-induced improvement in muscular endurance for ACE I/I homozygotes compared to ACE D/D homozygotes. Importantly, the ACE I/D polymorphism causes large inter-individual differences in serum ACE activity. Because the ACE D/D genotype is characterized by high plasma ACE activity and potentially blunted endurance exercise training response, it appears likely that ACE inhibitors (ACEi) have the potential to improve the outcome of exercise training for ACE D/D homozygotes. Thus, in the present study the investigators apply a randomized double-blind placebo-controlled longitudinal design to investigate whether pharmacological inhibition of ACE activity can amplify the exercise training response in healthy humans carrying either the ACE D/D or ACE I/I genotype. The study hypothesis is that inhibition of ACE activity in healthy humans with the ACE D/D genotype will amplify the health beneficial effects of exercise training while this is not the case in ACE I/I homozygotes.

Conditions

• Exercise
• Angiotensin-Converting Enzyme Inhibitors

Interventions

Type	Name	Description
DRUG	Enalapril	Participants will be assigned to daily administration of ACE inhibitors (Initially 5 mg Corodil® 'Enalapril' daily followed by up to 20 mg daily dependent on the blood pressure response) combined with an 8-week training period.
DRUG	Placebo	Participants will be assigned to daily administration of placebo (5-20 mg CaCO3) combined with an 8-week training period.
