Sports Nutrition: Water - Hydration - & Athletic Performance


Every athlete has a different hydration requirement, which changes due to weather conditions. Generally, it is recommended that everyone drink 64 ounces of water a day to stay in a fully hydrated state. Sweating, which often occurs during physical activity, releases water and sodium from the body. To function at their peak, athletes need to replenish this loss through water and sports drinks. Neglecting to replace both fluid and sodium loss results in dehydration, which causes impaired mental focus, impaired energy metabolism, and an imbalance in electrolyte levels. It also results in rapid fatigue and decreased energy.

As a general rule, athletes should drink 16 ounces of water or sports drink 2 hours before activity. They should then consume another 8 ounces 30 minutes before activity. During an activity, fluids should be readily available for athletes as they need it. Coaches should watch for athletes expelling a higher-than-normal amount of sweat and ensure that the athlete is drinking as much as they need. It is recommended that athletes replenish half of the fluid lost by sweat.

Athletes involved in short-term activity lasting over 30 seconds are at a high risk for dehydration due to the intensity of the activity. These athletes should drink the recommended fluids before their activity and replenish the lost fluids as soon after finishing as possible. Short-term activity lasting less than 30 seconds has little effect on dehydration and does not pose a hazard.

Athletes involved in long-term activity, such as running, cycling, and skiing for more than 30 minutes need periodic fluid intake to reduce dehydration levels, even though this may cause cramping and gastrointestinal problems. To prevent such problems, athletes should train themselves to take in the necessary liquid to accustom their bodies to the fluid.

During an activity, athletes should drink 8 ounces of fluid every 20 minutes. For activities over 40 minutes, water is not sufficient, because it does not provide the necessary sodium intake to maintain electrolyte levels. If water is all that is available, mixing 1 teaspoon of salt per liter of water is enough to maintain the balance.

Too much water can cause another problem, hyponatremia, when the sodium levels in the body are too low. Symptoms of hyponatremia are nausea, muscle cramps, disorientation, slurred speech, confusion, and inappropriate behavior. This occurs when there is an intake of water to replace lost fluids, but no intake of salt to replace lost sodium. Hyponatremia is much more dangerous than dehydration, and it is important that coaches monitor how much fluids are taken in to ensure that their athletes do not run the risk of suffering from this potentially life-threatening disease. The old method of ?drink as much as you can? is now seen as dangerous because of the effects it can have in lowering sodium levels.

If your athletes are still unclear as to how much fluid to drink, there is a simple urine test that determines the hydration levels of a person. Athletes should have clear urine, showing that they are fully hydrated. If the urine is dark or there is restricted flow, the athlete needs more fluids. There is not a set amount for each person, so it is important that as a coach, you train your athletes to learn what their individual bodies need.

Sports Nutrition Degrees



Now, the $2 billion-worth sports nutrition industry has moved away from the plain-tasting protein powders into a bigger pool of choices for customers. Available in almost any drug stores or supermarkets are energy bars, meal replacement products, protein powders, individual items (e.g., creatine, L-carnitine), amino acids, herbs, prohormones (hormone precursors); vitamins; minerals; and combination products. Because of this the sports nutrition nutraceutical industry is considered a 'niche' market and an offshoot of the mainstream food industry.

Competition factors for the Sports Nutrition Market

Product/brand differentiation

Because of greater saturation and competition in the marketplace sports nutrition products look alike and sound the same. Maintaining a brand that stands apart from the rest is difficult but a thing to strive for.

Research-substantiated claims.

Consumers� ability to make intelligent choices should never be underestimated. People place more faith endorsements by university professors and doctors and claims backed by independent research than by endorsements Sports Nutrition Home Study by celebrities.

Core products and strategies

A good strategy now is to focus development of core products or integrating with large food and pharmaceutical concerns (e.g., Powerbar, BalanceBar).

E-commerce

For small companies that cannot or will not rely on strong distribution relationships, e-commerce is an increasingly attractive option.

Basis for marketing strategy

The factors for competition stated above have been gleaned from researches of what consumers are willing to pay for. Overall, customers want:

Something New

Retailers and consumers clamor for "new," whether it means new forms of delivery (gels, effervescent tablets, functional beverages), new applications of or combinations with existing products, or all-natural sports nutrition products that are free of artificial ingredients and solvents.

Excellent Tasting All-natural products

Consumers are also looking for products that taste good and are easy to take. Taste is a major feature that can either make or break a product. The hunt is on for manufacturers to come up with better and new flavors.
