This study aimed to verify the level of knowledge and hydration habits of physical activity practitioners. We evaluated 185 subjects (25,2 ± 5,9 years) with a questionnaire containing objective questions on the sport practiced, knowledge and habits of hydration during exercise. We used descriptive statistics and the results are presented using percentage distribution. The most practiced was the weight (71.3%), with time practice over 18 months (40.5%). That most of the evaluated hydrates (72.4%), regardless of the season (61.0%), worry about the liquid ingested (63.7%), consume water as liquid replenishes (56.5%), worry about the type of clothing and fabric ( 69.1%), do not weigh before and after exercise (45.4%) and prefer to consume cold liquids (72.4%). Regarding knowledge about hydration, most indicated that hydration must occur before the sensation of thirst (74.0%), Gatorade was the best known electrolyte replenishes (55.9%) and consumed (69.1%), and the orange flavor the most used (35.2%). Most do not know how to hydrate (48.6%) and do not know the function of isotonic (40.0%), and had not received guidance on the correct form of hydration (60.0%). Despite having a level of knowledge about hydration, this is still incipient. It is necessary to expand the number of individuals using the weighing technique, as well as the students’ knowledge about the function of an isotonic and the best strategies of fluid replacement during activity. Key words: Dehydration, Sports nutrition, Performance, Health.

Introduction: The present study investigated the effect of supplementation with different doses of maltodextrin. Before, during and after an exercise protocol with continuous loads predominantly aerobic blood glucose levels and cardiovascular variables in patients with T2DM. Materials and Methods: Six patients diagnosed with T2DM, aged between 40 and 60 years, were supplemented with different doses of carbohydrates (100 mg/kg, 1g/kg e 2g/kg), for 40 minutes of aerobic exercise at 40% heart rate reserve (FCreserve) evaluating cardiorespiratory parameters and blood glucose. We used the ANOVA, and considered significant value than p<0.05. Results: The results show a significant difference in blood glucose for the supplementation of 100 mg/kg of maltodextrin in relation to the group 1 g/Kg (32%, 66 mg/dL; p=0,03) and supplemented with 2g/kg (38%, 79 mg/dL; p=0,02) 40 minutes during the exercise protocol at 40% of FCreserve and 10 minutes after exercise. Discussion: Supplementation with 100 mg/kg maltodextrin can be an effective strategy for preventing rebound hypoglycemia after physical exercise. Conclusion: Control of rebound hypoglycemia with 100 mg/kg of maltodextrin. Key words: Diabetes mellitus, Carbohydrates, Glycemia, Exercise.

Ergogenic resources are often consumed in gyms due to the purpose of provide an improved performance in certain physical activities as competitive and aesthetic. Creatine is a supplement used in strength training that aims to assist in the yield strength and muscle hypertrophy in students and / or athletes. The aim of this review is to investigate the effects of the use of creatine supplementation on strength training for such beneficial improvements to the performance of strength and hypertrophy in men with individuals experienced in training. We conclude that creatine supplementation associated with strength training for men proves to be an efficient practice that can contribute to being part during the periodization of strength training. Key words: creatine, strength training, hypertrophy.
