ABSTRACT

The physical exercise has demonstrated to be a preventive factor for the development of chronic- degenerative diseases. The continuous aerobic physical exercise decreases the insulin resistance and the atherogenic lipid profile; however, the intermittent aerobic exercise has been less studied in relation to its effects on lipid metabolism. The metabolic response to both kinds of exercise depends on the intensity, energy expenditure, diet, fitness and health status of the subject, among others. The present work shows the effects of two types of exercise, continuous and intermittent, on the acute changes of glucose, triacylglycerols (TAG), and the HDL-cholesterol (HDL-C), in young, healthy, active males, with and without systematical training. The results show that in trained subjects with continuous exercise the HDL-C was increased 7.3%, whereas on the intermittent exercise was observed increases on glucose 6%, TAG 10.4% and HDLC 12.8%. In contrast, in subjects without training the continuous exercise decreases the glucose values 13%, but TAG and HDL-C values increased 10.4 and 12.8%, respectively. The continuous exercise caused different responses in both subject groups. The results suggest that glucose levels in the continuous exercise are influenced by the physical fitness, whereas in the intermittent exercise the changes on glucose and TAG seem to depend on the exercise intensity. To explain the changes of HDL-C, in both kinds of exercise and in both populations, it was suggested that they are the result of the combination of training, energy expenditure and intensity of the exercise.
