Association between ACE and ACTN3 genetic polymorphisms and the effects of different physical training models on physically active women aged 50 to 75

Abstract

The aim of this study was to analyze the association between ACE (DD + ID versus II) and ACTN3 (TT + TC versus CC) polymorphisms in the response of multicomponent physical training programs and combined in the health parameters of physically active women aged 50 to 75 years. Participants were randomly divided into two groups: multicomponent training and combined training. Intervention lasted 14 weeks, 180 minutes a week. Genomic DNA was extracted from blood samples and genotyping analyzes were performed by conventional and real-time PCR. Associations were observed between polymorphisms in anthropometric measurements, blood pressure, physical capacity and quality of life in both models physical training, with improvement in group II -(ACEmulticomponent training in terms of abdominal circumference and sit-to -Combined training in terms of waist circumference) and TT + TC group (ACTN3 -multicomponent training in tests of muscle strength and mental quality of life domain, and combined training in body mass index, waist circumference, diastolic blood pressure, upper limb strength and cardiorespiratory capacity). Fourteen weeks of multicomponent and combined physical training in physically active women aged 50 to 75 years resulted in greater health benefits for genotypes II (ACE) and TT + TC (ACTN3).
