ABSTRACT

Scientific research about metabolic response, by means of blood tests, during large swimming (LS), in swimmers with several kinds of nutrients, could give us important information about suitable diet, in accordance with the variability of blood parameters during LS.
The metabolic response quantified by means of capillary blood tests, before, during (each hour) and after 12 hours of swimming, in a swimmer who was feeded with a mixture of proteins/ carbohydrates, was studied. Blood parameters: glucose, triacyglicerols, urea, lactic acid, creatine kinase, total proteins, albumin, globulins, total cholesterol, HDL-cholesterol, LDL-cholesterol and VLDL-cholesterol, were quantified. It is possible to separate the metabolic adaptation in four periods, in accordance with the changes in such parameters: acute (1 hour), intermediate (2-4 hours), advanced (4-8 hours) and chronic (after 8 hours) adaptation.
In sequence, the changes we found were: glucose used decreased (limited storage), triacyglicerols used decreased (unlimited storage) and proteins used increased (supplementary storage), as energetic sources during advanced adaptation. Creatine kinase, after 2 hours of swimming, increased step by step until the even was finished. Albumin increased and globulins decreased during the swimming. HDL-cholesterol increased and LDL + VLDL-cholesterol decreased during the swimming, as well as total cholesterol. We are going to research the metabolic response in the same swimmer with a diet which contains just carbohydrates, in order to compare the blood parameters during the swimming with the results we obtained in this work.
