Feeding well: an essential criterion for athletes
Healthy eatinghas a major importance to succeed in thesport. This gives energy, helps to buildmuscleand to recover more effectively. Let's see why balancing your meals is the key to achieving your sporting goals.
Influence of power on performance
A varied and balanced diet improves the quality of the workouts. According to Birmingham University, athletes who consume a lot of protein and complex carbohydrates see their performance increase by 20% compared to those who have a less structured diet.
Eating properly ensures the energy required during the exercise, helps the muscles repair and recover quickly. Carbohydrates feed the body glycogen for good endurance, while proteins repair muscles after exercise.
The dangers of inadequate feeding
There are dangers when you eat badly by practicing asport, such as injuries, fatigue and diminished performance. Use testimonies and studies to illustrate these threats. Poor diet can cause nutritional imbalances, increase the risk of injury and cause gastrointestinal problems.
The International Sports Nutrition Society reports that athletes with a destructured diet are twice as likely to suffer from cramps, nausea and digestive disorders during and after the exercise. Emily Infeld, an Olympic athlete, testifies that her wrong eating choices have caused serious digestive problems in competitions, thereby reducing her performance.
Essential nutrients for athletes
What are the nutrients an athlete needs and how to get them? Here are the macronutrients and micronutrients needed to give the best of yourself.
Macronutrient requirements
Protein, carbohydrates, and lipids are essential. Proteins are vital for muscle repair and growth. They must make up 10 to 35% of the daily intake, with sources such as meat, fish, eggs, dried vegetables, and tofu. Carbohydrates are the main source of energy, especially during prolonged efforts, and must make up 45-65% of daily calories.
Complete cereals and fruit are therefore recommended. Fat, although often neglected, is essential to produce energy and absorb vitamins. These should account for 20 to 35% of daily calories, especially unsaturated fatty acids in fatty fish and vegetable oils.
| Macronutriments | Recommended sources | Use |
|---|---|---|
| Proteins | Chicken, fish, eggs, legumes | Muscle repair and growth |
| Carbohydrates | Complete cereals, fruit and vegetables | Supplying energy |
| Lipids | Fatty fish, nuts, olive oil | Energy production and absorption of vitamins |
The importance of micronutrients
Vitamins and minerals are equally vital for athletes. Vitamins B, C, D, and E as well as iron, calcium and magnesium are needed for energy and bone and muscle health. Athletes should eat varied with green vegetables, fruits, nuts, and dairy products. For example, calcium is crucial for bones, and vitamin D helps absorb calcium.
Why probiotics are useful
Probiotics play a major role in digestive health. They balance the intestinal microbiome and improve the digestion and absorption of nutrients. Studies show that probiotics reduce digestive disorders and strengthen the immune system. The Bio-K+ SCI Pro is recommended for its proven benefits.
Tips for eating better by doing sports
Some nutrition strategies before, during and after the effort to maximize your performance and recovery. Ideas to plan your meals and snacks.
What to eat before going to sports
Meals and snacks before exercise must be rich in complex carbohydrates to provide constant energy. For example, a bowl of oatmeal flakes with fruits and nuts, or a chicken and avocado sandwich on whole bread 2 to 4 hours before exercise is ideal to avoid insulin fluctuations.
- Breakfast: Bowl cake with oatmeal
- Lunch: Full rice with chicken and grilled vegetables
What to eat during exercise
To stay hydrated and energized during a long session, consume isotonic drinks and carbohydrate-rich snacks. Energy gels and drinks like ISO Aptonia are perfect.
What to eat after the effort to recover well
Good post-exercise nutrition is essential to repair muscles and restore energy. Choose high protein and carbohydrate meals. You can have grilled salmon with sweet potato purée, or fruit protein smoothie.
