Hydration and Electrolyte Balance
Proper hydration and electrolyte balance are crucial for optimal sport performance. Athletes lose water and electrolytes through sweat during physical activity, and failure to replace these fluids and minerals can lead to dehydration, fatigue, and decreased performance. Here are some key points to consider when it comes to hydration and electrolyte balance:
Fluid Intake
Athletes should aim to drink enough fluids to replace the water lost through sweat during physical activity. The amount of fluid needed will vary depending on factors such as the duration and intensity of the activity, the environment (e.g., temperature, humidity), and the individual’s sweat rate. A general guideline is to drink 500-700 ml of water per hour, but this may need to be adjusted based on individual needs.
Sodium, Potassium, and Other Electrolytes
Electrolytes are minerals that help regulate fluid balance in the body. Sodium, potassium, calcium, and magnesium are some of the most important electrolytes for athletes. During exercise, these minerals are lost through sweat and need to be replaced to maintain proper electrolyte balance.
Sodium is the most important electrolyte for athletes, as it helps regulate fluid balance and is lost in large amounts through sweat. Athletes should aim to consume 500-700 mg of sodium per hour during exercise, which can be obtained through sports drinks or other sodium-containing foods.
Potassium is also important for fluid balance and muscle function. Athletes should aim to consume 200-400 mg of potassium per hour during exercise, which can be obtained through bananas, sports drinks, or other potassium-rich foods.
Calcium and magnesium are also important for muscle function and bone health. Athletes should aim to consume adequate amounts of these minerals through their diet, with a focus on calcium-rich foods such as dairy products and leafy greens.
It’s important to note that the amount of electrolytes needed will vary depending on the individual and the type of activity being performed.

Energy and Amino Acid Requirements for Sport Performance
Carbohydrate Intake for Endurance and Intensity
Pre-exercise Carbohydrate Loading
Pre-exercise carbohydrate loading is a technique used by athletes to maximize their glycogen stores before a competition or a high-intensity training session. This involves consuming a large amount of carbohydrates in the days leading up to the event, typically 3-5 grams per kilogram of body weight per day. This strategy has been shown to increase glycogen stores in the muscles and liver, which can improve endurance performance and delay fatigue.
Intra-exercise Carbohydrate Intake
Intra-exercise carbohydrate intake refers to the consumption of carbohydrates during exercise, typically in the form of sports drinks or gels. This strategy is used to maintain blood glucose levels and provide energy to working muscles during endurance events or high-intensity training sessions. Research has shown that consuming carbohydrates during exercise can improve endurance performance and delay fatigue, particularly in events lasting longer than 60 minutes.
One study found that cyclists who consumed a carbohydrate-electrolyte solution during a 40-kilometer time trial completed the trial faster than those who did not consume the solution. Another study found that runners who consumed a carbohydrate-protein supplement during a 5-kilometer run had improved time-trial performance and increased muscle glycogen levels compared to those who consumed a carbohydrate-only supplement.
In conclusion, carbohydrate intake is a crucial aspect of sports nutrition for endurance and high-intensity sports. Pre-exercise carbohydrate loading and intra-exercise carbohydrate intake have been shown to improve endurance performance and delay fatigue, and should be considered as part of a comprehensive sports nutrition plan.
Protein Requirements for Recovery and Growth
Timing of Protein Intake
Proper timing of protein intake is crucial for optimizing muscle recovery and growth after exercise. Research suggests that consuming protein before, during, and after exercise can maximize muscle protein synthesis, the process by which muscle tissue is repaired and rebuilt. Specifically, consuming protein before exercise can help to increase muscle protein synthesis during exercise, while protein consumed during or immediately after exercise can help to optimize muscle recovery and reduce muscle breakdown.
Optimal Protein Sources
When it comes to choosing protein sources, there are a variety of options available to athletes. Animal-based sources such as chicken, beef, and fish are commonly used due to their high protein content and easy availability. However, plant-based sources such as beans, lentils, and tofu can also be effective sources of protein for athletes, particularly for those following a vegetarian or vegan diet.
It’s important to note that not all protein sources are created equal. For example, whey protein, a popular supplement among athletes, has been shown to be particularly effective at promoting muscle recovery and growth. Additionally, some plant-based protein sources may be lower in certain essential amino acids, which are necessary for muscle protein synthesis. As such, it’s important for athletes to choose a variety of protein sources to ensure they are getting all the necessary nutrients for optimal performance.
