Nutrition For Optimal Health & Performance!

Common supplements to increase an athlete's energy include: Caffeine, Guarana, Vitamin B12, and Asian ginseng. Caffeine is used to improve energy and increases metabolism. Guarana is another supplement that athletes take to enhance their athletic ability, it is frequently used for weight loss and as an energy supplement.

This was attributed to the effects of caffeine, sucrose and Vitamin B in the drink - however scientific consensus does not support the efficacy of using Vitamin B as a performance enhancer. To explain the performance improvement the writers report an increase in blood levels of epinephrinenorepinephrine and beta-Endorphin.

Caffeine takes the place of adenosine in your brain, attaching itself to the same neural receptors affected by adenosine, and causing your neurons to fire more rapidly, hence caffeine's stimulating effects. The main use for athletes to take dietary proteins are for hormones, oxygen transport, cellular repair, enzymes and conversion to fuel.

In addition, it aids in performance and recovery. Dietary protein intake for well-trained athletes should occur before, during and after physical activity as it is advantageous in gaining muscle mass and strength. Characteristics of this particular diet include the type of exercise, intensity, duration and carbohydrate values of diet.

Traditionally, sports drinks such as Gatorade and Powerade, are consumed during and after exercise because they effectively rehydrate the body by refueling the body with minerals and electrolytes. Electrolytes regulate the bodies nerve and muscle function, blood pH, blood pressure, and the rebuilding of damaged tissue.

A recovery drink is supposed to replenish the sugar lost, and help recover the muscles to be able to workout at full intensity by the next time they workout. When compared to plain water or sports drinks, research suggests that chocolate milk is more effective at replacing fluids lost through sweat and maintaining normal body fluid levels.

Athletes drinking chocolate milk following exercise-induced dehydration had fluid levels about 2 percent higher on initial body mass than those using other post-exercise recovery beverages. These results allowed for prolonged performance, especially in repeated bouts of exercise or training. These compounds which are related to the hormone testosterone, can quickly build mass and strength, but have many adverse effects such as high blood pressure and negative gender specific effects.

The supplement, Creatinemay be helpful for well-trained athletes to increase exercise performance and strength in relation with their dietary regimen. The findings show that there are no substantial benefits from the extra intake of these supplements, yet higher health risks and costs.

Factors that may affect an athlete's nutritional needs include type of activity aerobic vs. Most culprits that get in the way of performance are fatigue, injury and soreness.

Introduction to the importance and influence of nutrition on exercise

A proper diet will reduce these disturbances in performance.Journal of the International Society of Sports Nutrition (JISSN) focuses on the acute and chronic effects of sports nutrition and supplementation strategies on body composition, physical performance and is aimed at researchers and sport enthusiasts focused on delivering knowledge on exercise and nutrition on health, disease, rehabilitation, training, and performance.

Aug 11,  · Nutrition is increasingly recognized as a key component of optimal sporting performance, with both the science and practice of sports nutrition developing rapidly.1 Recent studies have found that a planned scientific nutritional strategy (consisting of fluid, carbohydrate, sodium, and caffeine) compared with a self-chosen nutritional strategy.

Sports nutrition is a topic of constant change and has grown as a dynamic field of clinical study. Research continues to advise improved nutritional guidelines and support for both active adults and competitive athletes. Sports nutrition is the study and practice of nutrition and diet as it relates to athletic performance.

It is concerned with the type and quantity of fluid and food taken by an athlete, and deals with nutrients such as vitamins, minerals, supplements and organic substances such as carbohydrates, proteins and fats. The healthy performance of college athletes is foundational to the work of the NCAA Sport Science Institute.

That’s why we promote adequate nutrition, hydration, sleep, science-driven strength and conditioning efforts and the responsible use of supplements consistent with NCAA drug policies. In most cases, protein and carbohydrates are the two dominating factors when it comes to the overall nutrition plan for the athlete.

This is because tactical athletes are constantly put in a high stress and or extreme circumstances consisting of resistance and endurance type activities which stress the body.
