Correlation of the lactate threshold and threshold glycemic in exercises of located muscular resistance with supplementation of maltodextrina in different percentages

Abstract

The objective of this study was to verify the ergogenic effect of the supplementation with different concentrations of maltodextrina (6%, 12% and 18%) and placebo in the training of located muscular resistance. Moreover, to correlate sanguineous lactate with the circulating glucose. For in such a way, 7 individuals of the masculine sex had been selected, physically active. The participants had been submitted the four previous exercises (supine rectum, squat, pulley coasts and flexor table), measured 1RM and repetitions until the imperfection mechanics with 50, 60 and 70% of 1RM. Serving to find the adequate load 50% of 1RM in the biggest muscular groupings. The training was composed for fifteen exercises, “alternated for pursuing” with only one series until the imperfection mechanics with 50% of 1RM, interval of ninth seconds between series. To each five exercises were collected: Lactate, glycemia, two tests has controlled (test of supine in one minute and horizontal jump) and the supplementation (150ml), which was divided at four moments (600 ml) for session of trainings. Conclusion, the carbohydrate ingestion was capable to attenuate the deleterious effect of the training of located muscular resistance in the tests has controlled, supine in one minute, with 18% of carbohydrate 33.67, while with placebo 29.60 results in (average and shunting line standard), horizontal jump, carbohydrate 12% 192.92, placebo 184.58, now with carbohydrate 18% 180.83, being the lesser measured distance. It is necessary that it is carried through more invasive studies correlating such facts.
