Sports nutrition is the study and use of nutrition and diet to support the healing and rebuilding process after intense physical activity, as well as achieving athletic performance in competitive events, all while boosting general health and wellness. Nutrition is a significant aspect of many sports training programs, with strength and endurance sports being particularly popular. Sports nutrition analyzes the type and quantity of fluids and food consumed by athletes. It also covers the intake of essential nutrients including protein, carbs, fats, vitamins, and minerals.

Nutritional requirements are determined by gender, type of activity, BMI, workout stage (pre-workout, intro-workout, recovery), and time of day (e.g. some nutrients are used more effectively by the body while sleeping than when awake). Fatigue, injury, and soreness are the most common causes that affect cognitive performance. A healthy diet can help to alleviate these performance issues. The key to a healthy diet is to eat a wide variety of foods and to obtain all of the essential nutrients.

Supplements

Dietary supplements come in a variety of forms, including tablets, capsules, gummies, powders, drinks, or energy bars that contain one or more dietary components such as carbohydrates, proteins, fats, vitamins, minerals, fiber, and herbs. Athletes may want to consider using dietary supplements to help them perform better in competition. Other supplements include performance-enhancing (steroids, blood doping, creatine, and human growth hormone), energy (caffeine), and recovery supplements (protein, BCAAs).

Energy Supplements 

Energy supplements are sometimes used by athletes to help them exercise more often. Caffeine, Vitamin B12, Ashwagandha, Rhodiola Rosea, Beetroot, Glutamine, Betaine, and Creatine are some of the most common supplements used to boost an athlete’s energy levels.

Caffeine has been shown in studies to improve endurance, high-intensity exercise, and power sports. However, it appears that it is most beneficial to trained athletes. It helps improve athletic performance in trained athletes when taken in low-to-moderate doses (3-6 mg/kg) but does not result in any further improvement when taken in larger doses (9 mg/kg). When opposed to coffee, caffeine has a stronger ergogenic effect when consumed in an anhydrous form. Caffeine has been demonstrated to improve vigilance during periods of prolonged exhaustion, as well as periods of prolonged sleep deprivation.

Recovery Supplements

Athletes use more energy than the ordinary people, and their bodies require additional calories to recuperate from intensive activity. Protein is essential in an athlete’s diet because it helps in the repair and strengthening of muscular tissue. Thousands of different proteins make up our bodies, each serving a unique function. They are the structural components of our cells and tissues, as well as many enzymes, hormones, and immune cell-active proteins. Throughout our lives, our bodies’ proteins are constantly repaired and replaced. This procedure necessitates a steady supply of amino acids. This means we need to consume dietary protein to meet our body’s amino acid requirements. Protein is required for cell and tissue growth, thus getting enough of it is crucial during periods of rapid growth or increasing demand.

Protein supplements, in addition to high-quality protein foods, are an extremely beneficial addition for athletes. Indeed, protein supplements are digested faster than whole foods, making them an effective recovery strategy.

Performance Enhancers

Athletes, particularly bodybuilders, may opt to utilize prohibited substances such as anabolic steroids in the extreme case of performance-enhancing supplements. These substances, which are related to the hormone testosterone, can rapidly increase muscle mass and strength, but they also have a series of adverse effects, including high blood pressure, headaches, nausea, vomiting, acne, weight gain, restlessness, and poor sleep.

Creatine, in combination with a healthy diet, may help athletes improve their exercise performance and strength. The most abundant free amino acid in the human body is glutamine, which can be found in food and supplements. For well-trained and well-nourished athletes, glutamine is thought to play a role in stimulating anabolic processes such as muscle glycogen and protein synthesis. Androstenedione, chromium, and ephedra are three more supplements that have been studied extensively. The data suggest that using these supplements in excess has no significant advantages, but does increase health risks and expenses.
