Dissociação do polimorfismo do gene da enzima conversora de angiotensina com a força, volume e qualidade muscular em mulheres sedentárias

Introduction: Strength and muscle mass reflect the interactions between environmental factors and genetics. Objective: To analyze the influence of the genotype of the angiotensin converting enzyme (ACE) on strength, muscle volume, quality and total-body skeletal muscle mass in middle-aged sedentary women. Methods: The sample consisted of 32 women divided into two groups according to the I/D polymorphism that underwent assessments of muscular strength tests of 1RM. In addition muscle volume measurements of the quadriceps and biceps by ultrasound were obtained, and the muscle quality of the biceps and quadriceps. Results: There was no difference on muscle strength, volume and quality neither of the quadriceps and biceps muscles, nor in the total-body skeletal muscle mass. Conclusions: The findings of this study did not demonstrate an important role of the polymorphism in the ACE gene in determining the phenotypes of strength, muscle volume and quality of middle-aged sedentary women.

Avaliação da pressão arterial em mulheres sedentárias e sua relação com a força muscular - doi: 10.5020/18061230.2012.p337

Objective: To compare the ambulatory blood pressure in women with different values of relative muscle strength. Methods: Data from 21 (aged 33.8±8.0 years) sedentary women from Vila Telebrasilia was collected during the period of November 2010 to July 2011. The volunteers were submitted to the evaluation of the handgrip strength and ambulatory monitoring of blood pressure (AMBP) for a 72-hour period. Following the evaluation of handgrip strength to determine the absolute muscle strength, an adjustment in the body mass was made, in order to determine the relative muscle strength. Based on the relative value of muscular strength, the sample was divided into tertiles to compare systolic, diastolic and mean blood pressure during the periods of 24 hours, daytime and night-time, by using an one-way ANOVA, followed by Bonferroni test when appropriate, with a significance level of p<0.05. Results: Significant differences were found for systolic blood pressure between tertile 1 (99.3±12.2) and tertile 3 (106.8±11.1) in the night-time (P<0.05). Values of mean blood pressure were also significantly different between tertile 1 (70.2±6.3) and tertile 3 (80.3 ± 8.8) in the night-time (p<0,05). Conclusion: Women with higher relative muscle strength present lower values of blood pressure during night-time.
