Starting nutritional intervention preparation

Nutritional strategies used before, during and after exercise should take into account a number of objectives. They should provide energy, support goals and exercise capacity by taking into account various factors related to nutrition and fatigue. These may include dehydration, hypoglycemia, depletion of glycogen resources, electrolyte imbalance, discomfort from the digestive tract (walking, nausea, feeling hungry).

1. Food preparation for launch

Nutritional strategies based on the preparation for the start depend on several factors, including: sporting events, environmental conditions, individual preferences, appetite, food tastes and rules applicable during competitions. Start preparation should begin a few weeks before the start of the event by introducing snacks during the activity and trying out a meal before the race. Nutrational strategies that appear a few days before the event should be based on increased availability of carbohydrates for optimal performance.

2. Food snacks during the performance

The introduction of snacks during prolonged workouts can keep the effort as intense as possible. Any discomfort resulting from a malfunctioning digestive tract can affect the quality of the exercise performed. By introducing snacks while exercising, we can train the digesting tract reduce the feeling of discomforts. Regular intake of snack during activity improves absorption and emptying the stomach. This technique allows us to prepare the body for performance and ensures that no unpleasant situation occurs during our runs or meets.

3. Hydration during activity

The vast majority of physically active people start their activity with an inadequate level of hydration, and the reduced fluid status is negatively impacted by the exercises performed. 510 ml of fluid per kg of body weight should be supplied before training within 24 hours. The purpose of exercise hydration is to prevent dehydration of less than 2% body weight. It is estimated that during training fluid loss can range from 0.3 l/h to as much as 2.4 l/hr. Routine body measurements before and after exercise give images of the intensity of fluids to be taken during long-term exercise.

4. Nutritional strategies prior to launch day

Pre-starter meals should be based on light, well-tolerated fiber products. On this day, it is advisable to give up heavy-fat, fatty and spicy products and a high amount of caffeine. It is admissible to eat steamed, low fat, grilled foods. If there is a tendency to stomach and intestinal problems during exercise, the amount of fiber should be reduced.

5. Hypoglycemia is a method of avoiding it

In studies conducted in the 1970s, it was observed that carbohydrate intake per hour before exercise caused high blood glucose and insulin levels to occur 45 minutes after exercise. This condition is often referred to as hypoglycemic suppression of the hippocampus than hypoglicampus activity. It is claimed by the head of the impaired person that these symptoms include nausea and hippocampius discomfort.
