Abstract

Background and objectives: A body of evidence confirms the benefits of cardiac rehabilitation (CR) in coronary heart disease (CHD) patients, but it remains unclear whether it enhances the antioxidant potential. The aim of the study was to assess the influence of an eight-week aerobic cycloergometer-based CR program on serum total antioxidant capacity (TAC) and other CHD risk factors. Materials and Methods: The study involved 36 men with CHD (55.2 ± 9.0 years). TAC was assessed with two methods: ferric reducing ability of serum (TAC-FRAS) and 2.2-diphenyl-1-picryl-hydrazyl (TAC-DPPH). Aerobic capacity was evaluated during a submaximal exercise test. TAC and other anthropometric, biochemical and physical activity/fitness measures were performed twice: before the beginning and after termination of CR. Results: Aerobic capacity was higher (7.0 ± 2.6 vs. 8.0 ± 2.5 MET—metabolic equivalents; p < 0.01), but values of resting diastolic blood pressure were lower (81.9 ± 7.6 vs. 77.4 ± 8.9 mmHg; p < 0.01) after termination of CR. Other classic cardiometabolic, anthropometric, and biochemical measures did not change with CR. No difference in TAC-FRAS was found after CR, whereas TAC-DPPH was significantly lower (16.4 ± 4.0 vs. 13.2 ± 3.7% reduction; p < 0.01). Conclusions: Antioxidant potential measured as TAC-DPPH, but not as TAC-FRAS, decreased with the CR program. The recognized health benefits of CR are not related to augmented serum antioxidant status. View Full-Text
