The Intersection of Nutrition and Exercise
The relationship between good health and nutrition is well-established. The impact of nutrition on athletic performance has become a science in itself. Whether you are a professional athlete, a weekend sports enthusiast, or a dedicated fitness goer, a nutritionally adequate diet forms the foundation for improved performance.
Balancing Your Daily Nutritional Intake
The basic dietary regimen should be sufficient to:
Provide enough energy and nutrients to meet the demands of training and exercise.
Enhance adaptation and recovery between training sessions.
Enable the athlete to achieve optimal body weight and body fat levels for performance.
Provide adequate fluids to ensure maximum hydration before, during, and after exercise.
Promote the short and long-term health of athletes.
Anatomy of an Athlete's Diet
An athlete's diet should essentially mirror that recommended for the general public, with energy intake distributed into:
45 to 65% from carbohydrates
15 to 25% from protein
20 to 35% from fat.
Athletes who engage in strenuous exercise for more than 60 to 90 minutes daily may need to increase their energy consumption, particularly from carbohydrate sources.
Guidelines for carbohydrate and protein intake based on grams per kilogram (g/kg) of body weight are also available.
The Role of Carbohydrates in Exercise
During digestion, carbohydrates are broken down into sugars (mainly glucose), which provide the body's primary energy source. Glucose can be converted into glycogen and stored in the liver and muscle tissue, serving as a critical energy source during exercise.
Essential Carbohydrates for Fuel and Recovery
The recommendations for carbohydrate requirements shift depending on the duration, frequency, and intensity of exercise. Athletes are advised to adjust their carbohydrate intake for fuelling and recovery to match their exercise level.
Training with Low Carbohydrate Availability
Some athletes opt to train with low carbohydrate levels. While there is accumulating evidence that carefully planned periods of training with low carbohydrate availability may enhance some of the muscle's adaptations to the training program, the benefits of this approach to athletic performance remain unclear.
Pre-event Meal Preparation
The pre-event meal forms an essential part of the athlete's pre-exercise preparation. Consuming a high-carbohydrate meal 3 to 4 hours before exercise has a positive effect on performance.
Eating During Exercise
During exercise lasting more than 60 minutes, an intake of carbohydrate is required to maintain blood glucose levels and delay fatigue.
Post-Exercise Nutrition
Rapid replacement of glycogen is crucial after exercise. Athletes should consume carbohydrate-rich foods and fluids, particularly in the first one to 2 hours after exercise.
Protein and Sporting Performance
Protein plays a critical role in supporting exercise adaptations and post-exercise recovery and repair.
Using Nutritional Supplements
A well-planned diet will meet your vitamin and mineral needs. Vitamin and mineral supplements will only be beneficial if your diet is inadequate or you have a diagnosed deficiency.
Hydration and Alcohol Consumption
Dehydration can impair athletic performance and, in extreme cases, may lead to collapse and even death. Athletes should ensure they consume plenty of non-alcoholic fluids before, during, and after exercise.
