Physical Exercise (PE), more precisely Strength Training (PT) has been demonstrated with an effective prevention and non-pharmacological treatment for women who go after the period of menopause, the present decrease in BMD at different bone sites analyzed in bone densitometry examinations. So, this update of literary study, were reviewed articles that met the inclusion criteria of the theme: BMD, postmenopausal women, exercise-based strength training and diet with calcium and concluded to be essential to establish exercise programs this period of life that produce stress and load on bone tissue, specifically strength training along with an adequate intake of bioavailable calcium sources, main nutrient of bone mineral content.

Introduction: The soccer is a type of sport with intermittent exercises with variable intensity, is world renowned and very practiced in many countries. The energy demands of training and competition requires players to consume a diet rich in carbohydrates. Thus, carbohydrate supplementation is a nutritional strategy that also allows the maintenance of blood glucose. Hydration is also an important factor that must be considered before, during and after exercise, since the chronic state of dehydration and heat stress during a football match may limit performance and be detrimental to the player. Objective: To analyze the influence of a carbohydrate solution in improving hydration and blood glucose during a football game adult players from the team base Baependi city in Minas Gerais. Results: The supplementation of a carbohydrate drink at 6%, provided an increase in glycemic index at the end of the match, as well as a smaller weight loss. Discussion: By providing exogenous carbohydrate there is less demand from endogenous glycogen stores, which attenuates the glucose decrease, increases muscle glycogen / liver and the availability of blood glucose, avoiding negative influences on performance. In addition, the carbohydrate drink prevents dehydration, avoiding thus the fatigue. Conclusion: The ingest of a carbohydrate drink at 6% for football players kept the high blood glucose at the end of the game, besides reducing the percentage of weight loss.

Grocery posture for several hours and a work of repetitive stress can lead to a painful, disabling the individual to develop their activities. This study aimed to verify the efficiency of the practice of laboral gymnastics (LG) in reducing pain of officials of the administrative sector and identify possible nutrients that may aggravate inflammation in the offered diet. 30 employees from the administrative section of a steel manufacture mill. Two groups were randomized: a control group sedentary and the group Laboral Gymnastics (LG) which participate effectively in LG sessions three times a week at Gymnastics Pause in the morning. The perception of pain condition and quality of life questionnaire were assessed at program start and end respectively on the three-month program, a dietary history was collected during the business day search. The criterion for choosing the company has never participated in a structured exercise program on the desktop. The results suggest that the LG has been satisfactory in reducing the level of pain, improve quality of life and reduce the stress of the samples of group fitness participants, as well, was effective in assessing the food offered in business and to identify possible precursors to increase the painful inflammation. The three months of practice of LG seems to have been enough to encourage physical activity and provide an improved quality of life of workers and could be easily implemented achieving a good compliance rate.

Introduction: The fluids imbalance caused by sweating during exercise can alter the physical ability and perceived exertion impairing athletic performance Objective: To verify the presence of dehydration and to evaluate the athletes performance by testing different forms of oral rehydration. Materials and Methods: Ten judokas, eight males and two females, have held four training sessions with different forms of hydration, free water intake (AL) intake of sports drink free (GL), controlled intake of water (AC) and controlled intake of sports drink (GC). The hydration status was determined by analysis of urinary staining and percentage of weight loss and the level of performance through the test of arm strength. Results: Based on the coloration of urine, at pretraining entire sample had some degree of dehydration. When comparing the pre and post workout, the groups of controlled consumption decreased to 15% the percentage of significant dehydration. Groups of controlled consumption showed better results both in the percentage of weight loss or the number of push-ups in the final yield advantage for the GC. Discussion: Drinks containing 6% to 8% carbohydrate and small amounts of sodium and potassium appear to promote greater benefits than the water in activities lasting more than an hour. Conclusion: The ingestion of a controlled independently of the substrate promoted the best results in all aspects evaluated. Key words: Judo, Dehydration, Hydration, Performance.
