Sports Nutrition Trends
For long, athlete’s training teams remained squarely focused on refining exercise regimes to increase the performance of athletes. Over the 20th century, though, the importance of modern sports nutrition was understood to be an integral part of athletes’ training, performance, and recovery, with everything from balanced diets to supplements refined to improve athlete’s wellbeing. In this article, we’ve explored the evolution of the field and some current nutritional trends shaping the professional sporting world.
Intro to Athletic Eating Habits
To help contextualize modern sports diet regimes, we’ve covered the early years of nutrition in athletics, leading up to the nutrition revolution in the latter half of the 20th century. We’ve then tracked how this is used to aid both training and performance.
From there, we’ve looked at the importance of diet and supplementation in recovery, whether it’s in injury rehabilitation or sleep. To close out this guide, we’ve shared insights into the biggest nutrition trends emerging in the sporting world and their global impact.

The Early Years of the Sports Diet
The evolution of athletic eating has been a long and winding one, beginning with unscientific superstitions and myths to the highly technological approach today. Before the 20th century, athletes’ approach to nutrition was generally focused on maintaining energy levels. Nutrition was generally impacted by traditional wisdom and cultural eating norms rather than knowledge of how specific nutrients impacted performance.
For example, early athletes tended to favor calorie-dense foods such as meat and bread, with more of a focus on quantity than quality. After the first Olympic Games, athletes and their trainers began to experiment with different food combinations and how they could affect performances. Cyclists and marathon runners in particular noticed the impact of consuming heavy foods on endurance.
That said, the approach was still based on anecdotal evidence and intuition as opposed to scientific understanding. It would be decades until nutritional science was taken more seriously and found widespread acceptance by athletes. Now, most teams in high-profile sports featured at the best online sportsbooks will have dedicated teams focused solely on nutrition.
The Nutrition Revolution
One of the earliest examples of sports nutrition research came in the 1920s when doctors studied the blood sugar levels of runners in the Boston Marathon. They found that those with the lowest levels were the most fatigued at the end of the race, which indicated the role of carbohydrates in performance.
The 1930s saw advancements in biochemistry and physiology impact nutritional science greatly. German scientist Nathan Zuntz investigated the impact of certain nutrients on physical performance, and his research was further expanded during World War II to understand food’s impact on soldier’s performances and endurance.
In the 1950s, Swedish exercise physiologists began studies on carbohydrate storage in muscle glycogen. They found that carb intake could have sizable impacts on athlete endurance, and the concept of “carb loading” was born. This has remained fundamental to endurance sports such as cycling and marathons.
The 1960s and 1970s saw scientific methods improve even further. Advances in metabolic testing and biochemical analysis achieved valuable insights into how different nutrients interact with the human body. By tracking the metabolic process in real-time, they began to form an understanding of how the body turns nutrients into energy.
Athletes and coaches began to work closely with nutritionists to develop sophisticated fueling strategies. At this time, sports drinks such as Gatorade came to the market to rapidly offer electrolyte and carbohydrate replacement. As the 21st century approached, more emphasis was given to formulating personalized nutritional plans.
Understanding that each individual’s metabolism and physiology were unique, coaches created personalized plans that met their needs. The importance of an individual diet approach during training, performance, and recovery was discovered, launching a new era in modern sports nutrition.
Diet in Training
A rounded sports diet plays a pivotal role in preparing athletes for competitive performances. Working with a team of coaches and nutritionists, the tailored nutritional plans will align with their specific sports and physiology. Teams will seek to find a good balance of macronutrients such as carbs, proteins, and fats while ensuring sufficient food intake to achieve their desired results.
For high-intensity activities, carbohydrates are the primary source of energy. As scientists in Sweden discovered, carbs are stored as glycogen in muscles and liver and help to fuel prolonged periods of activity. Complex carbohydrates that take longer to digest are favored for sustained energy, with whole grains, fruits, vegetables, and high-fiber foods a key component of the best sports diet plan.
Protein is essential for muscle growth and repair. Depending on the athletic activity, up to two grams of protein per kilogram of body weight daily is generally recommended. This intake can help to stop the degradation of lean body mass. Quality protein sources include lean meats such as chicken and fish, eggs, dairy, and plant-based proteins such as legumes.
Sometimes, these nutrients may be found in sports diet supplements too. While fat has often been demonized in diet trends, healthy fats are crucial for endurance activities to provide long-lasting energy. These can be found in nuts, seeds, avocados, and fatty fish. Hydration is an essential component of energy and digestion too. It’s not just about what foods are eaten in sports nutrition, but the timings of consumption. Consuming nutrient-rich meals two hours before training can ensure sustainable sources of energy.
Diet for Performance
Depending on the length of the sports performance, nutritional uptake can be recommended for maintaining energy levels and reducing fatigue. However, these will tend to be easily digestible foods and liquids that replenish glycogen stores. Often, energy gels, chews, and sports drinks such as Gatorade are recommended for glucose and electrolytes.
During longer events, small portions of dried fruits or bananas can deliver glucose quickly. Hydration has a vital impact on physical and mental performance, so regular reuptake of water and sports drinks based on the environmental conditions and athlete sweat rate should be factored in.
Athletes in endurance events lasting over 90 minutes will benefit from additional protein while performing. This will help prevent muscle fatigue. Easily consumed food such as protein and energy bars are commonplace during competitive performances. What’s important is that the nutrients are delivered efficiently and according to the individual needs.
Diet in Recovery
A post-performance nutrition plan is essential for any athlete to quickly restore energy reserves and mend muscles. Administered correctly, this can reduce recovery times to help athletes get back to training or competition. Within the first two hours of activity completion, a carbohydrate-heavy meal is recommended.
A recovery meal should also contain up to 30 grams of high-quality protein to stimulate muscle protein synthesis. If possible, athletes should consume a smaller snack within 30 minutes after the performance. This will prepare the body for the heavier meal later. Anti-inflammatory foods such as berries and leafy greens can also promote faster recovery.
Several modern sports nutrition studies have also uncovered the detrimental effects of alcohol on recovery, so athletes should avoid this in the hours following a performance. Foods that are high in calories and low in nutrients also do little to aid recovery and could increase inflammation.
Emerging Nutritional Trends
Sports science has a tangible impact on mainstream nutritional trends, so it’s common to see a cross-over between standard diet trends and sports nutritional trends. Recently, the impact of fasting on fat-cutting and lean muscle retention has resulted in intermittent fasting being adopted during some training regimes.
The use of wearable devices that track metabolic data in real-time has also been integral for nutritional testing, offering insights into the best times to refuel. Gene testing has resulted in more refined data to accurately map an athlete’s nutritional requirements, with artificial intelligence offering in-depth analysis of complex metrics.
To supplement athletic eating, many have also looked to compounds such as nootropics to aid with athletes’ mental performance. There is also a greater emphasis on improving gut health to reduce inflammation and aid digestion, with athletes encouraged to eat more diverse foods to create more diversity in the gut microbiome.
The sports diet has come a long way since the 1900s, from being informed by generation wisdom to being based on scientific breakthroughs and technology-informed nutritional strategies. As the science is improved, the findings have had a major impact on society at large, improving not just the health of athletes but everyday people.
