Fitness replenishment formula -
With the overwhelming amount of information, it can be challenging to figure out what you should be doing to support your active lifestyle. All activities are not created equal, so we break down how to fuel your body to give it what it needs to perform and recover!
Calories are the first piece of the puzzle when looking at maintaining a healthy and active lifestyle. According to the International Society of Sports Nutrition, those who participate in a general fitness program minutes per day 3 times a week can usually meet their nutritional needs by following a normal, balanced diet as their caloric demands are around calories per session.
When we look at athletes at moderate intensity levels, the caloric burns are significantly higher at upwards to kcals per hour. This will continue to increase as the t does and during higher volume training weeks.
Elite and professional athletes will exceed these levels significantly as the workout intensifies. So what does this all mean? These can include illness, reduced sleep quality, incomplete recovery, and hormonal fluctuations increased resting heart rate, apathy towards training and increased stress.
Diving deeper than simply just eating enough calories, athletes, in particular, should be mindful of the kinds of foods and more specifically what macro and micronutrients they provide.
There is no lack of research out there that emphasizes the importance of carbohydrates, especially for those athletes who are looking to perform in team sports or endurance racing.
When athletes compete in events up to three hours carbohydrates are the predominant fuel source used by working muscles. Endurance athletes are encouraged to consume carbohydrates before, during depending on the duration of the session , and after exercise to optimize performance and ensure there is enough carbohydrates readily available for your training sessions.
Replenishing carbohydrates after moderate to high-intensity exercise will restore glycogen levels, the stored form of carbohydrates, in both the muscles and liver. This will promote adequate recovery after sessions and adequate caloric intake, as energy restriction tends to interfere with an athlete's ability to meet their higher carbohydrate needs.
These carbs should ideally be coming from a diet rich in vegetables, fruits, legumes, and whole grains to provide a range of vitamins and minerals. When exercising at a moderate to high intensity for longer than 2 hours it is recommended that carbs be taken in session to prevent fatigue and improve performance.
This has also been shown to be beneficial in athletes participating in intermittent or team sports when the intensity, duration, and pre-competition intake of carbs are taken into consideration.
It's not simply about getting enough protein but focusing on getting high-quality sources. Different types of protein are broken down and absorbed at varying rates. Opt for foods like chicken, fish, egg whites, and lean cuts of beef. Protein powders made from whey, egg and pea protein are great for meeting protein needs, but choose food sources whenever you can.
Spacing out your protein every hours in ~20g portions has been shown to have the greatest effect on muscle growth and repair. In a world where we've gone from low fat to high-fat diets , this brings up lots of controversy for athletes.
Getting adequate fat helps to maintain energy balance, replenishes intramuscular triacylglycerol stores, and ensures that we are getting enough essential fatty acids.
While past research shows a high-fat diet providing no performance benefits and increased gastrointestinal issues, more recent studies show limited, mixed results on the efficacy of a high-fat diet, ketogenic diet for athletes.
When looking for fat sources in your diet strive for mostly unsaturated fats; think avocados, walnuts, flax, and canola oil while limiting saturated fats found in animal products and processed foods as much as possible!
Tracking calories and macronutrients with apps like MyFitnessPal can be a helpful tool and strategy for some athletes. Putting a focus on a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats throughout the day with proper fueling pre and post workout is key.
Knowing that when you are training more and with more intensity, you will need more to meet the increased demands you are putting on your body! Kerksick C, Wilborn C, Roberts M et al. J Int Soc Sports Nutr. Cermak N, van Loon L. The Use of Carbohydrates During Exercise as an Ergogenic Aid.

Glycogen can be easily metabolized into glucose, which provides immediate energy to fuel the brain, nervous system, and muscles during exercise.
As glycogen stores are depleted, the body begins to break down fat to burn for fuel, especially during low- to moderate-intensity activity. In the latest stages of prolonged exercise when glycogen stores are at their lowest, the body begins to break down skeletal muscle protein for glucose production.
Physical activity can also induce muscle growth, also known as hypertrophy. Weight lifting and other resistance training exercises are commonly used to increase skeletal muscle mass, but cardiovascular exercise like running can also spur muscle growth. Physical activity causes structural damage to muscle fibers, especially when muscles are challenged with multiple repetitions of heavy weights.
A variety of factors influence how rapidly muscles grow with exercise, including the amount of weight lifted and the number of repetitions. Spotlight on protein powder Powdered protein can come from a variety of sources, including eggs , milk e. Protein powders are dietary supplements and are not reviewed by the FDA for safety or effectiveness.
They can often contain non-protein ingredients, including vitamins and minerals , thickeners, added sugars , non-caloric sweeteners , and artificial flavoring. Casein and whey contain all essential amino acids and are easily absorbed by the body, but their speed of absorption differs.
Casein, on the other hand, is not soluble in water and is digested more slowly than whey—when ingested, it forms a clotted gel in the stomach that provides a sustained slow release of amino acids into the bloodstream over several hours.
However, multiple studies have found no clear evidence that casein is more effective than any other protein source for satiety or weight loss. It is a common alternative to milk protein for vegans or people with dairy sensitivities or allergies. Soy protein is absorbed fairly rapidly by the body, although it is not as bioavailable as animal-based proteins.
One study found that soy protein promoted muscle protein synthesis significantly more than casein protein when consumed by healthy young men at rest and after leg resistance exercise, but that soy protein was inferior to whey protein in increasing muscle protein synthesis.
Pea protein is rich in eight of the nine essential amino acids; it is low in methionine, which can be obtained from other sources including rice and animal proteins. There is limited research on the effects of pea protein. One double-blind, randomized, placebo-controlled study found that men aged 18 to 35 years who ingested 50 grams of pea protein daily in combination with a resistance training program over 12 weeks experienced similar increases in muscle thickness compared to those who ingested the same amount of whey protein daily.
Hemp protein powder is derived from the seeds of the hemp plant. Although there is little research on the use of hemp protein powder as a workout supplement, it contains omega-3 fatty acids and a number of essential amino acids.
However, it is not a complete protein, as it has relatively low levels of lysine and leucine. References Council for Responsible Nutrition. Economic Impact of the Dietary Supplement Industry.

Pre-workout supplements are designed to provide energy and aid endurance throughout a workout. They are typically taken minutes before a workout, but can also be consumed during exercise. Below are common ingredients found in pre-workout supplements that the Academy of Nutrition and Dietetics, Dietitians of Canada, and the American College of Sports Medicine have highlighted as having evidence-based uses in sports nutrition.

You simply cannot recover properly if your body remains depleted of fluids after a workout. You also should avoid waiting until you feel thirsty. Instead, your workout routine should include a rehydration step during and right after you are done so you can maintain consistent hydration.
