Efeito da suplementação com vitamina D sobre parâmetros de estresse oxidativo em adultos obesos hipertensos submetidos a exercícios físicos

Abstract

Objective: To analise the effect of vitamin D3 supplementation on oxidative stress parameters in hypertensive subjects after a single session of resistance training and aerobic intermittent treadmill walking test. Methods: The subjects underwent supplementation with 800 mg/day of vitamin D3 for 11 days. On seventh day underwent resistance training and on eleventh day conducted intermittent aerobic treadmill walking test. The blood pressure (BP) and heart rate (HR) were measured before, during and after exercise and blood samples were collected for analysis of biochemical parameters before and after the sessions of exercise. Results: Subjects were classified as aging adults, obese, hypertensive and with increased cardiac risk. The vitamin C levels did not change, while the levels of vitamin E and protein carbonyl showed antioxidants effects. Conclusion: Vitamin D3 is shown reducing per se the levels of carbonyl protein thus demonstrating that it has an antioxidant effect and attenuating sarcopenia by the increase in muscle mass.
