Objective The purpose of this study is to determine the prevalence of consumption sport drinks among physically active and athletes in Riyadh city, K.S.A.

Methodology The study is cross sectional (descriptive study), five-hundred healthy athletes and physically active lived in Riyadh city will be volunteered as subjects. Anthropometric measurement during study will be determined.

Introduction The athletes who consumes sport drinks before, during, or after the competition or training aims to improve their performance by minimizing the impact of the factors that impair the performance and cause fatigue. R.J Maughan, University Medical School, Fosterhill, Aberdeen AE25 220, UK: The sports drink as a functional food: formulations for successful performance, 1998

Definition "A sports drink is a beverage designed to help athletes rehydrate when fluids and electrolytes are depleted after training or competition. Replacement promotes proper rehydration, which is important in delaying the onset of fatigue during exercise…” Byars A. and others, Comparing two sports drinks effects on indices of aerobic Performance, 2008, Journal of the International Society of Sports Nutrition.

Types of sports drinks According to its osmolality, there are three types of sport drinks; isotonic, hypotonic, and hypertonic, all of which contain various levels of fluid, electrolytes and carbohydrate. Blood has an osmolality of 280 to 330mOsm/kg

Types of sports drinks 1- Isotonic fluids: contains electrolytes and 6 to 8% carbohydrate. Isotonic fluids quickly replaces fluids lost by sweating and supplies a boost of carbohydrate

Types of sports drinks 2- Hypotonic fluids: contains low level of carbohydrate. And quickly replaces fluids lost by sweating. Suitable for athletes who need fluid without the boost of carbohydrate 3- Hypertonic fluids: contains high level of carbohydrate

Carbohydrate and Exercise Consuming carbohydrate before exercise can promote performance by raises muscle and liver glycogen stores. Consuming carbohydrate during exercise maintain blood glucose levels thus improving performance. After exercise, consuming carbohydrate can rapidly facilitates refilling of carbohydrate stores Dunford, M. Sports Nutrition. 4 th edition. American Dietetic Association. 2006

Fluid, Electrolytes, and Exercise ingestion of adequate water and electrolytes can restore the plasma volume and osmolality to normal levels. Dunford, M. Sports Nutrition. 4 th edition. American Dietetic Association. 2006

The General Ingredients of Sport Drinks Water: Water is the primary ingredient in all sports drinks. CHO:The type of carbohydrates doesn't appear to be critical, all glucose, sucrose, and oligosaccharides have been shown to be effective. R.J.Maughan, University Medical School, Fosterhill, Aberdeen AE25 220, UK: The sports drink as a functional food: formulations for successful performance, 1998

The General Ingredients of Sport Drinks Electrolytes: Athletes use sports drinks to replenish the electrolytes lost during intense physical activity. Artificial Colors and Flavors: Adding flavours to sport drinks have been shown to increase fluid intake relative to plain water. www. wardmulroy.com R.J.Maughan, University Medical School, Fosterhill, Aberdeen AE25 220, UK: The sports drink as a functional food: formulations for successful performance, 1998

Sports Drink Side Effects The consuming of sports drinks lead to store the sugar and carbohydrates as fat in the body, in case of not doing any physical activity. Copyright ClutchWave LLC, 2009

Conclusion Human body needs an adequate supply of carbohydrate, electrolytes, and fluids before, during, and after exercise to promote a proper performance and improve restoration, replenish, and rehydration processes. These needs can be easily covered by sport drinks.

Recommendations Cont, 1.To maintain blood glucose levels and supply proper energy, an intake of 5 to 7 g carbohydrate/kg/day is recommended for general training needs and 7 to 10 g/kg/day is recommended for endurance athletes. Ultra-endurance athletes' needs may exceed 10 g/kg/day. 18% to 24% of this needs can be obtained from sport drinks.

Recommendations 2. To rehydration process, an estimate of 3.7 liters/day for males and 2.7 liters/day for females is assumed to be adequate in minimally active people and for individuals who train or work, their daily water needs may exceeds 10 liters/day.
