Characteristics of a diet and supplementation of American football team players: following a fashionable trend or a balanced diet?

Background: American football is based on speed and strength efforts players forming both defensive and offensive units in the team. Players' diet's may differ with regard to the variety of physical efforts performed and their different nutritional needs. Objective: The aim of the study was to evaluate a diet and the supplementation, including the comparison of both the defensive and offensive player's formations, which may constitute a background of sportsmen' balanced menus permitting them to achieve better sports results. Material and methods: The study included 44 American football players (24 defensive, 20 offensive players). The study group completed a three-day-dietary recall containing the time of consumption as well as a questionnaire about a type and amount of supplements used, including questions of one or multiple choice. Results: The mean age of defensive players was 25.1±5.8 years, while of offensive players was 23.4±3.7. The mean body mass equaled 101±15.6 kg vs. 88.7±22.2 kg. The mean height of defensive players was 183.8±6 cm vs. 182.4±7.3 cm of offensive players. Offensive players consumed on average 2471.9±838.6 kcal/24 hs, whilst defensive players 3086.1±908.9 kcal/24 hs. The mean level of cholesterol level consumption equaled 667.81±300 mg in defensive players, while 546.2±285 mg in offensive players. Of energizing preparations, protein powder supplement and coffee were most frequently chosen by players. Conclusions: Defensive unit players were characterized by higher consumption of certain nutritional components and more frequent diet supplementation. A too low caloric intakes well as water, vitamin D, carbohydrates and dietary fiber intake was observed in both units. A high intake of high level cholesterol products requires reduced consumption of saturated fatty acids and increased consumption polyunsaturated fatty acids.

Comparison of diet and physical activity of children and adolescents with patients after cancer treatment

Background: Properly balanced diet and exercise are an essential element of healthy living for children and adolescents. Particular attention should be paid to nutrition and physical activity among juniors after cancer treatment, which is one of the most important elements of the convalescence period. Objective: The aim of the study was a comparative analysis of diet, physical activity of healthy children and adolescents with patients after cancer treatment. Material and methods: The study involved 60 children and adolescents; 30 healthy juniors and 30 patients after treatment for cancer. An analysis of diets based on a 3-day 24-hour nutrition diary. The questionnaire surveyed collected data about participation and physical activity preferences. Statistical program-Statistica 12.0, published by StatSoft, was used to develop the results. Results: Both groups were characterized by increased consumption of proteins and carbohydrates. Insufficient fat intake was shown in comparison with the recommended amounts in all study groups. It was observed that in the group of patients after treatment, vitamins B1, A, E and D intake was higher than in their healthy peers. Determinants of the choice of physical activity among children after cancer treatment was pleasure and fun, while among their healthy peers, aesthetic considerations (taking care of appearance). Conclusions: Children and adolescents after cancer treatmentin a much greater percentage covered of daily intake of nutrients than healthy children, and more willingly spent time on physical activity. Greater interest in physical activity in this group was probably due to previous restrictions related to illness and therapy.

Probiotic strains as the element of nutritional profile in physical activity ­ new trend or better sports results?

A diet, individually customized to the needs of sportsmen and sportswomen prepares them better for competition and achievement of better sports results. However, disorders of the gastrointestinal tract and frequently recurrent upper respiratory tract infections pose a common problem observed among athletes of disciplines such as triathlon, cycling and marathon. Diarrhea, splashing in the intestines or gastrointestinal bleeding make it difficult to start and win in the race. Recently researchers have paid special attention to the therapeutic effect of probiotic strains on the human body. Various probiotic strains may have a beneficial effect on elimination of disorders mentioned above among athletes of these disciplines. Still, researchers continue looking for answers to the question how a specific probiotic strain is able to reduce the risk of the gastrointestinal tract and the respiratory system disorders appearing during training or competition. Attention is also drawn to the possible impact of probiotics on the physical capacity athletes and their athletic performance. Probiotic strains properly applied may have a positive influence on the athletes' bodies, but still randomized controlled trials are required to prove this thesis.

The use of contraception for patients after bariatric surgery.

Obesity in women of reproductive age is a serious concern regarding reproductive health. In many cases of infertility in obese women, reduction of body weight may lead to spontaneous pregnancy, without the need for more specific methods of treatment. Bariatric surgery is safe and is the most effective method for body weight reduction in obese and very obese patients. In practice there are two bariatric techniques; gastric banding, which leads to weight loss through intake restriction, and gastric bypass, leads to weight loss through food malabsorption. Gastric bypass surgery (the more frequently performed procedure), in most cases, leads to changes in eating habits and may result in vomiting, diarrhea and rapid body mass reduction. There are reliable data describing the continuous increase in the number of women who are trying to conceive, or are already pregnant, following bariatric surgery. Most medical specialists advise women to avoid pregnancy within 12-18 months after bariatric surgery. This allows for time to recover sufficiency from the decreased absorption of nutrients caused by the bariatric surgery. During this period there is a need for the use of reliable contraception. As there is a risk for malabsorption of hormones taken orally, the combined and progestogen-only pills are contraindicated, and displaced by non-oral hormonal contraception or non-hormonal methods, including intrauterine devices and condoms.
