Carbohydrates and Sports Performance: Fueling Your Performance

Introduction 

When it comes to sports performance, fueling your body properly is essential. One crucial aspect of a well-balanced diet for athletes is carbohydrates. Carbohydrates serve as the main source of energy for our bodies, providing the fuel needed to perform at our best. In this article, we will explore the different forms of carbohydrates and discuss their impact on sports performance. Let's dive in! 


The Importance of Carbohydrates 

Carbohydrates are an essential macronutrient that our bodies rely on for energy. During exercise, our muscles use stored carbohydrates, known as glycogen, to provide the necessary fuel. This fuel allows athletes to perform at their peak level and sustain their efforts for a more extended period. 


Two Forms of Carbohydrates Simple Carbohydrates: 

  1. Simple carbohydrates, also known as sugary carbs, are quickly digested and absorbed by the body. They provide a rapid energy boost, making them beneficial for short bursts of intense activity. Foods such as fruits, honey, and table sugar contain simple carbohydrates. 

  2. Complex Carbohydrates: Complex carbohydrates consist of long chains of sugar molecules and take longer to digest. These carbohydrates provide a more sustained release of energy, making them ideal for endurance activities and longer duration workouts. Foods such as whole grains, legumes, and vegetables are rich in complex carbohydrates. 





The Glycemic Index 

The glycemic index (GI) is a scale that measures how quickly carbohydrates raise blood sugar levels. Foods with a high GI value are digested and absorbed rapidly, leading to a quick spike in blood sugar. On the other hand, foods with a low GI value are digested more slowly, resulting in a gradual rise in blood sugar levels. However, the GI scale only considers the biological response of that single food item. In real world application, athletes are not just eating rice or pasta. Instead, they often pair these foods with protein and fat sources which will alter the GI index. 




Finding the Right Balance 

When it comes to sports performance, finding the right balance of carbohydrates is crucial. Consuming too many simple carbohydrates before a workout can lead to a rapid increase in blood sugar, followed by a crash. On the other hand, not consuming enough carbohydrates can result in low energy levels and decreased performance. Athletes should aim to consume a mix of simple and complex carbohydrates before exercise. This combination provides both an immediate energy boost and a more sustained release of energy throughout the activity. Depending on the athlete’s gut tolerance, training intensity and duration, and satiety, consuming a light snack comprised of mainly simple sugars can be beneficial to performance. Experimentation and trial and error may be necessary to determine the ideal carbohydrate intake for each individual.



FAQ: Carbohydrates and Sports Performance


Q: What is the CHO recommendation for strength training?

A: The GSSI recommends 4-7g/kg for strength training as this may aid in total work capacity. 

Example, athlete A weighs 68kgs so CHO intake should range between 272-476g/d.


Q: How soon before exercise should I consume carbohydrates? 

A: It is recommended to consume 1-4g of CHO per kg of body weight approximately 1 to 4 hours before exercise. This timing allows for proper digestion and absorption of the carbohydrates, providing a steady source of energy during the activity. 


Q: Can low-carbohydrate diets affect sports performance? 

A: Yes, low-carbohydrate diets can negatively impact sports performance. Since carbohydrates are the body's primary source of energy during exercise, inadequate carbohydrate intake can lead to fatigue, decreased endurance, and impaired recovery. It is essential to fuel your body properly with carbohydrates to optimize sports performance.
