Summary
Middle age for women is a period of great changes in both physical and mental status. As working hours are lengthening, there is less and less free time, the time needed for recreation and leisure activities is very limited, so women live in a time where food consumption and stress are increasing as time goes by (Andrijašević, 2010). Physical activity in fitness has a strong positive effect on human health, especially in the pathogenesis of diseases that make up the metabolic syndrome (insulin resistance, type 2 diabetes, hyperlipidemia, hypertension, and overweight). Food and physical activity largely determine human health (Joint FAO / WHO Expert Consultation, 2003), and increased energy consumption is one of the main causes of increasing numbers of overweight people (Cutler, M., Glaeser, EL, Shapiro, JM 2003). There is compelling evidence that increasing intake of high-energy foods, rich in fats and sugars, contributes to the development of obesity (Joint FAO / WHO Expert Consultation, 2003). The main purpose of this paper is to assess the prevalence of use of nutritional supplements in people who exercise in fitness centers, what are the reasons for their use and the types of supplements that are most often used in fitness in order to create an overview general and identify the main reasons for using these substances
