Hydration and Athletic Performance
Menu
When it comes to physical performance, the importance of a well-balanced diet cannot be overstated. The food we consume before a workout plays a crucial role in fueling our bodies and enhancing our performance. This blog post will delve into the optimal structure of a pre-workout meal, highlighting the dos and don'ts, and providing practical recommendations for hydration and supplementation.
A pre-workout dinner should be light, slightly alkalizing, and predominantly composed of liquid or semi-liquid dishes. It's essential to keep protein intake low, as an excess of protein can lead to longer digestion times, which may cause discomfort during your workout.
The focus should be on dishes rich in vegetables and legumes, such as pureed soups and vegetable creams, along with digestible dishes like baked poultry or fish croquettes. Including cooked vegetables and fresh fruits (preferably consumed on an empty stomach for better digestion) can also be beneficial.
When planning your pre-workout meal, it's crucial to avoid combining protein and starchy foods in the same dish or meal. The contrasting effects these foods have on gastric secretion can lead to longer digestion times, which is not ideal before a workout.
Additionally, certain combinations like meat and milk, or eggs with milk and its derivatives, should be avoided. Acidic foods and drinks should not be combined with proteins and starches, as their acidity can slow down the digestion of these nutrients.
Stimulants like tea, coffee, or chocolate can increase the heart rate and metabolism, leading to a temporary sensation of well-being or reduced fatigue. However, these effects can also cause nervousness and insomnia post-workout. Therefore, it's advisable to limit the consumption of these stimulants before your training session.
Proper hydration is crucial before, during, and after exercise. A general guideline is to consume 400-600 ml of water in the two hours leading up to your workout, and continue to hydrate throughout the session with 150-300 ml every 15-20 minutes.
If your workout is prolonged (more than 90 minutes), consider using hypotonic sports drinks, which contain carbohydrates and electrolytes. These drinks can help prevent dehydration and mineral deficiencies caused by sweating. Sweat contains essential minerals like sodium, chlorine, magnesium, and potassium, and deficiencies in these minerals can lead to disorders and performance issues.
The ideal workout drink should contain a maximum of 5% carbohydrates and essential electrolytes like chlorine, sodium, potassium, and magnesium. The concentration of the drink should be isotonic or hypotonic to ensure quick absorption from the intestine to the blood.
During periods of high energy demand or when optimal nutrition cannot be achieved, multivitamin and multimineral supplements can be beneficial. However, it's crucial to read all the components carefully before taking any supplement. Always ensure the supplement is approved by the relevant health authorities.
A well-planned pre-workout meal can significantly enhance your performance, while improper food combinations can hinder it. Remember, the key is to consume a light, alkalizing meal, stay hydrated, and consider supplementation when necessary. Always listen to your body and adjust your dietary habits accordingly to achieve your fitness goals.
