What Should A Swimmer Eat For Peak Performance? The 2024 Diet Guide

Whether you’re just dipping your toes into the world of competitive swimming or a seasoned pro slicing through the water, one thing unites all swimmers: proper nutrition.

As you swim lap after lap, your body demands more than just physical training; it requires nutritional support. This article explains what a swimmer should eat before and after practice or a swim meet to enhance performance, ensure recovery, and maintain overall health.

This article is your go-to resource, providing insights into the swimmer’s diet and other important tips. 

What To Eat Before Training Sessions

What swimmers eat before training impacts their ability to focus and perform swimming drills. The right food energises them and provides sufficient nutrients to support their physical activity.

However, keep in mind that the timing of pre-training meals and snacks is critical. Consume a larger meal about 3-4 hours before training and a smaller snack 30 minutes to an hour before.

Here’s a list of what you should include in your diet as you prepare for practice. 

Carbohydrate-Rich Foods

Carbohydrates are the primary fuel source for swimming and other high-intensity exercises. In a study, it was discovered that carbohydrate-rich foods help improve the average swim performance of the participants. 

Consuming the following food before training ensures that the body has enough energy.

  • Wholegrain Cereals and Oats: These provide slow-releasing energy, ideal for long training sessions.
  • Fruits: Options like bananas and apples offer quick energy and are easy to digest. Bananas are excellent as they also provide potassium, which helps in muscle function.
  • Bread and Bagels: Preferably whole grain, these provide a good balance of carbohydrates and fibre.

Proteins

While not the primary fuel source, proteins are essential to repair and prevent muscle breakdown during intense training. 

  • Eggs: A versatile option, they can be boiled, scrambled, or made into an omelette.
  • Greek Yoghourt: It’s rich in protein and can be combined with fruits or honey for added carbohydrates.
  • Nut Butter: Spread on whole grain toast or crackers, they offer a good mix of protein and healthy fats.

Low-Fat And Low-Fibre Foods

It’s generally advisable to avoid high-fat and high-fibre foods right before training as they can cause discomfort or gastrointestinal issues.

  • Lean Meat Sandwiches: Using whole grain bread and lean meats like turkey or chicken.
  • Smoothies: Made with low-fat yoghurt and fruits, they can be a light yet energy-packed option.

Energy Bars

They can be a convenient source of carbohydrates and protein, but it’s important to choose bars with a good balance of nutrients and low in added sugars.

The key is focusing on easily digestible, energy-rich foods that provide sustained energy without causing gastrointestinal discomfort during long training sessions. This approach ensures that swimmers are adequately fueled and ready to perform at their best during training sessions​​​​​​.

What To Eat The Day Before A Swim Meet

When preparing for a swim meet, swimmers must focus on their diet to ensure optimal performance. What you eat in the 24 hours leading up to the event is crucial for ensuring you are adequately fueled and also in peak physical condition to perform your best.

Complex Carbohydrates

Complex carbohydrates must be included in a swimmer’s diet because they provide sustained energy release. This is because they are digested slowly, gradually releasing energy and stable blood sugar levels, which is key to avoiding energy spikes and crashes. 

As you prepare physically for the competition, consume complex carbohydrates such as whole grains, nuts, beans, brown rice, fresh and dried fruits and vegetables.

Healthy Fats

People generally avoid fats due to the misconception that all fats are unhealthy and contribute to weight gain, heart disease, and high cholesterol. However, not all fats are bad for health.

Foods rich in unsaturated fats, such as almonds, olive oil, avocados, and salmon or tuna) provide a feeling of fullness, helping to control hunger and manage weight effectively. So, is it okay to eat fats? The short answer is yes. 

Healthy fats are also a dense source of energy. When stored in the body, they provide a reservoir of energy that can be utilised during long-duration swim meets, especially when carbohydrate stores start to deplete.

Avoid the temptation of excessive carbo-loading. A balanced diet is more effective in the weeks and months leading up to the meet. 

What To Eat Hours Before The Swim Meet

Swimmers must eat a few hours before the meet to ensure they have a steady energy supply. But timing is critical as eating too close to the competition can lead to discomfort or gastrointestinal issues, while eating too early might result in depleted energy reserves.

Here’s a list of what you can eat hours before the competition:

  • Hearty Breakfast: A light but nutritious breakfast 3 to 4 hours before the meet is ideal, especially if the event is early. This could include foods like yoghurt and wholegrain toast.
  • Carbs and Protein-rich Food: If the event is later in the day, a more substantial carbohydrate- and protein-rich food 4 to 5 hours before the competition are recommended, such as a turkey breast sandwich with vegetables on whole grain bread. 
  • Small Snacks: A small snack can provide a final energy boost approximately one hour before the swim.

What To Eat During The Swim Meet

Competitions last a whole day, depending on the type of swimming event. If the swim meet spans an entire day, you must include a variety of nutrients in your snacks. This means a mix of carbohydrates for energy, proteins for muscle repair, and healthy fats.

Easily Digestible Snacks

Opt for snacks rich in carbohydrates and easy on the stomach. This is important because intense physical activity can slow down digestion, and easy-to-digest foods ensure quick energy availability. 

Recommended options include bananas, apple sauce, pita chips, bagels, dried dates, energy bars, pretzels, energy chews/gels, and chocolates.

Water Or Energy Drink

Swimmers can become dehydrated due to sweat loss despite being in the water. So, drinking plenty of water is a must. You may also consider sports drinks to replenish electrolytes and provide additional carbohydrates.

Avoid Simple Sugars

Simple sugars, such as those found in candy, soda, and baked goods, are not recommended because when they are absorbed into the bloodstream, they cause rapid spikes in blood sugar levels. 

While this might provide a short burst of energy, it’s typically followed by a sharp drop, known as a “sugar crash.” This crash can result in feelings of fatigue and lethargy, which are detrimental to athletic performance.

What To Eat Post-Swim

After a swim meet or training, consume a meal that aids in the recovery process. Ideally, the meal should balance carbohydrates, proteins, and fluids.

  • Carbohydrates: These are crucial for replenishing the glycogen stores depleted during swimming. Quality carbohydrate sources include rice, pasta, bread, and potatoes. These provide the necessary energy for recovery and prepare the body for future physical activities.
  • Proteins: You need protein for optimal muscle repair and recovery after strenuous exercise. Chicken, fish, eggs, and dairy products are excellent choices as they have the essential amino acids for muscle synthesis and repair. These foods can reduce muscle soreness and enhance recovery.
  • Hydration: Rehydrating after a swim is as important as eating the right foods. Water replenishes lost fluids, while energy drinks can restore lost electrolytes. These drinks help maintain electrolyte balance in the body, which is vital for muscle function and overall hydration.
  • Fruits and Vegetables: You should also consume a variety of fruits and vegetables for additional vitamins, minerals, and antioxidants, which are vital for overall health and can aid in recovery. They also contribute to hydration and can help replenish other nutrients lost during exercise.

Food Swimmers Should Avoid

Swimmers, like all athletes, need to be mindful of their diet, not just what to eat but also what foods to avoid. Certain foods can negatively impact a swimmer’s performance, energy levels, and overall health. Here are some types of foods that swimmers are generally advised to avoid:

  • High-Fat Foods: Foods that are high in fat, especially saturated and trans fats, can slow digestion and make athletes feel sluggish. This includes fried foods, certain cuts of red meat, and full-fat dairy products.
  • Highly Processed Foods: Processed foods contain substantial amounts of sodium and preservatives that can harm a swimmer’s health and performance. These include fast food, chips, and some frozen meals.
  • Sugary Foods and Drinks: Foods and beverages high in sugar, such as candy, soda, and some sports drinks, can lead to energy spikes followed by crashes. They also offer little nutritional value.
  • Excessive Caffeine: While some caffeine can benefit performance, too much can lead to jitteriness, increased heart rate, and gastrointestinal discomfort. This includes not just coffee but also energy drinks and some pre-workout supplements.
  • Alcohol: Alcohol can impair muscle recovery, hydration, and overall athletic performance. It also adds empty calories to the diet.

Maintaining Proper Nutrition

Swimmers burn a significant amount of calories during their training and competitions. The renowned Olympic swimmer Michael Phelps reportedly consumed around 12,000 calories daily during his peak training. This is several times the average daily calorie intake for most people.

While elite swimmers may consume a high number of calories to meet the demands of their rigorous training schedules, the calorie requirements for swimmers vary greatly depending on their training intensity, body composition goals, and individual metabolism. 

Therefore, maintaining proper nutrition and healthy weight is essential to a swimmer’s training regime. Here’s how you can do it:

  • Balanced Diet: Focus on a diet that includes a balance of carbohydrates, proteins, and healthy fats. Carbohydrates are crucial for energy, proteins for muscle repair, and fats for overall health.
  • Monitor Caloric Intake: Be mindful of the number of calories consumed versus expended. This balance can change depending on the intensity of training cycles.
  • Regular Weigh-Ins: Regularly monitoring weight can help swimmers stay on track with their goals, whether it’s maintaining, losing, or gaining weight.
  • Staying Hydrated: Proper hydration is essential as it affects metabolism and helps regulate appetite.
  • Avoid Fad Diets: Swimmers should avoid fad diets that promise quick weight loss, as these can be unsustainable and harmful in the long run. 
  • Incorporate Strength Training: Alongside swimming, strength training can help in maintaining a healthy muscle mass, which in turn can aid in managing a healthy weight.
