| Resumo: | Background: Few have analyzed the effects of different intensities of acute physical exercise on biochemical parameters of cardiovascular disease. Aim: To examine the acute effects of high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) on biochemical cardiovascular markers in obese male adults. Materials and methods: Twelve sedentary obese male subjects (28.4 ± 2.6 years old, BMI 35.5 ± 4.5 kg/m2, 39.8 ± 2.2% body fat) took part in this randomized, cross-over clinical trial. Three experimental sessions, at 7-day intervals, in random order, were carried out: (1) HIIE: 10 × 60 s at ~ 90% of maximal peak velocity, interspersed by 60 s of active recovery, (2) MICE: 20 min at ~ 70% of maximum heart rate, and (3) control session. A standardized breakfast was offered before the exercise sessions. Biochemical markers of cardiovascular risk (glycemia, total cholesterol and fractions, triglycerides, hepatic enzymes and nitrogen scores) were assessed pre-exercise, immediately post-exercise, and 60 min post-exercise. Results: In general, no significant interaction was observed, with the exception of creatinine, that had a statistically significant two-way interaction between time and condition, F(4,40) = 5.053, p < 0.05. There was a statistically significant two-way effect in time, F(2,22) = 5.906, p < 0.05 for AST, and a statistically significant two-way effect in treatment, F(2,22) = 13.477, p < 0.05 for glucose. Conclusion: In this context, HIIE seems to be a safe alternative to MICE for the prevention and management of obesity, as well as the disorders observed in this population |
