Triathlete’s Protein Consumption

Medical specialists are divided on the issue of how important protein is too good health. They discuss the timing of their consumption, the amount that should be taken in, and what kind is the most suitable for athletes and people who are very active.

It is suggested that the average adult consumes 0.8 g/kg of protein per day to sustain the nitrogen balance in their body. This is important, as a negative nitrogen balance signifies that muscle tissue is being utilized as an energy source.

The Recommended Dietary Allowance for protein for children is measured and expressed on a gram-per-body-weight basis which is higher than for adults. Also, the RDAs are increased for women during pregnancy [1.1 g/kg/day] and lactation [1.3 g/kg/day].

Keeping an even nitrogen level is essential for wellness, however, research now points towards the fact that the Daily Recommended Allowance may not be the right amount of protein required to achieve peak health.

In order to achieve that target, additional protein is essential, and research now indicates that athletes, active people and elderly people require even more.

Proteins that originate from food sources are continually changing form within the body, as they experience decomposition into amino acids, alteration into entirely different chemicals and, periodically, re-creation into brand new proteins.

It is also possible to use them too generate energy, which will heighten if either energy intake is low or protein intake is insufficient.

Muscle protein is used as an energy source, resulting in an adverted nitrogen balance. This is a very important issue that athletes have to face given their rigorous activity level.

It makes sense that people who are exercising or being active on a regular basis need more protein, and good-quality protein, each day than those who are mostly inactive and stay in one position all day.

Proteins of high-quality content the nine essential amino acids in proportions which meet the necessary requirements; proteins of animal origin are better quality than those from plant sources.

It is essential to have sufficient high-grade protein to maintain health and peak athletic performance but the recommended daily allowance (RDA) does not offer a single amount of required protein that is suitable for everyone.

How Much Is Enough

It is widely accepted that athletes should have higher protein intakes than those who are not active, however, this amount may differ greatly depending on factors such as the type of athlete, body mass, total energy consumed, the objective of gaining or losing weight, the intensity and length of physical activity, level of training, the quality of dietary protein, and the age of the athlete.

As a general rule, endurance athletes should consume between 1.2 to 1.4 grams of protein per kilogram of body weight, whereas strength and power athletes should have 1.2 to 1.7 grams of protein per kilogram of body weight, according to Christopher Mohr, PhD, RD, a weight-loss consultant and writer with Mohr Results in Kentucky.

The more training you do and the harder you work, the more protein your body needs. Research has suggested an amount of up to 2g of protein per kilogram of body weight should be taken to prevent muscle loss in athletes who have slashed their caloric intake.

Exercising increases the demand for protein intake but it also causes the muscles to make better use of the protein from one’s diet, even for seniors.

Research has shown that having the elderly participate in exercises of moderate intensity can improve how their body responds to protein intake. This could mean that regular activity may be useful in avoiding or treating the muscle breakdown typically associated with ageing.

Type of Protein to Consider

The International Society of Sports Nutrition advocates for the consumption of proteins of good quality.

This text emphasizes the use of whey protein isolate derived from milk, casein, egg whites, and soy protein isolate as essential sources of amino acids which are quickly absorbed by the muscles to enhance nitrogen balance and the synthesis of muscle proteins.

Studies have shown that leucine appears to be necessarily necessary for stimulating muscle protein production and that proteins which contain high levels of leucine may be the most effective way to respond to powerful physical exercise.

Certain experts propose that the superiority of protein in terms of its leucine amount is particularly crucial when eating little meals or when the consumed amount of protein isn’t enough to fulfil requirements.

The amount of proteins in an average American diet is typically around 8% leucine.

It is believed that consuming between 2.5 and 3.5 g of protein can promote muscle protein synthesis after a meal. Foods such as milk and another dairy, beef, chicken, fish, pork, peanuts, legumes such as beans and lentils, and soybeans are all especially high in leucine.

What about protein powder supplements? “They’re not necessary,” Mohr says. Do they provide quick and good quality food for people who don’t have a lot of time? Absolutely. Mix in some dairy, vegetables, and either nuts or nut butter, and you have a great portable meal.

When to Eat Protein

It is equally essential to determine when athletes should consume protein as it is to decide how much and what types of protein to eat. As a result of physical activity, muscle breaks down. If protein intake is low, that muscle isn’t replaced.

People who exercise regularly have less destruction of muscle proteins. But protein requirements are higher during intense training sessions.

Most people agree that consuming protein after physical activity, when the body can best utilize nutrition, will help to improve muscle protein synthesis and restore wellness.

Most people consume only a small portion of their total daily protein intake in the morning, roughly one-fifth in the afternoon, and the majority of it at dinnertime. It would be advantageous to divide our protein consumption over the day since our bodies are unable to store it, according to Mohr.

Donald Layman, a professor emeritus in the Department of food science and human nutrition at the University of Illinois at Urbana-Champaign, suggests that adults need a minimum of thirty grams of protein per two or more meals to uphold their muscles in good shape. Eating small meals throughout the day, such as breakfast or lunch, generally does not provide any advantages for muscle health as they usually contain less than 15 grams of protein.

Findings from a research report put out by The Journal of Nutrition suggest that spreading out protein intake among breakfast, lunch, and dinner results in 25% higher muscle protein synthesis than typical patterns of only eating the majority of protein at dinner, even when the overall amount consumed is the same.

Protein that is consumed over a day rather than just at certain meals may be particularly valuable for ageing individuals who exercise often. In comparison to younger people, older individuals have a higher threshold for the amount of protein required in one sitting to set off their muscle protein synthesis.

Timing of Protein Intake

It is essential to not only fulfil your daily necessities for protein and energy but also the time of the day to consume your protein and carbohydrates is vital for enhancing strength capabilities and getting back to health.

The ideal moment to take advantage of anabolic effects starts 1 hour before a workout and lasts until 24 hours following a session of strength training.


You should eat 15-20g of protein, take in 25-50g of carbohydrates, and drink 16-24oz of water within an hour before doing strength training exercises. If you are going to be doing aerobic exercise after your resistance training, it is important to increase your carbohydrate intake to replenish your body’s glycogen stores.

During a workout

It depends on whether or not you have already completed an endurance workout, a pre-workout snack was missed, or you will be doing an endurance workout immediately after a strong one, and how much fuel you need during a strength session.

It is generally not necessary to consume fuel during an activity unless extra energy is needed. In that situation, it would be beneficial to have a beverage with carbohydrates that is specially formulated for athletes. No matter what, make sure to have some water handy and begin exercising while already hydrated.


To promote muscle repair, rebuild glycogen, and have a positive effect on body composition, make sure to have either a snack or a meal that contains both protein and carbohydrates.

During the initial phase after a workout (0-45 minutes), have 15-25 grams of protein, 25-50 grams of carbohydrates, and 20 ounces of fluid for every pound you have sweated out in that session.

It’s important to remember that there is no benefit to having more than 40 grams of protein at one time regarding developing muscle. Even though bodybuilding circles tend to glorify the intake of protein, it is not necessarily the case that more is better.

If you take in more protein than is necessary, it can be used as energy, though it is not very efficient, or it can be stored as fat, which is probably not something you want.

What you eat close to your workouts is usually decided by how easy it is and how functional it is. Try to focus on snacks that are easy to take with you if you’re not sitting down for a meal. Some good ideas are Greek yoghurt and fruit, a peanut butter and jelly or honey sandwich, some low-fat cheese and crackers, a portion of chocolate milk, or a protein bar.

Maintaining a Positive Energy Balance

The energy that is used up in the process of breaking down and constructing muscle fibres is considerable, so if your caloric intake is inadequate it will slow down your ability to recover, which could eventually put your overall health and metabolism in danger.

When glycogen stores become depleted and the body has insufficient energy, it calls upon protein as an energy source by degrading muscular tissue. Hence, it is imperative to consume sufficient calories, particularly from carbohydrates, to keep up with energy needs and avoid unnecessary muscle breakdown.

As a demonstration, a vigorous strength workout could consume up to 30% of glycogen supplies, depending on the intensity and length of the session.

If you aren’t careful about eating when you are engaging in a combination of training and endurance training that is shorter now than usual, your glycogen stores will be exhausted.

Optimal Protein Choices

The most powerful nutrient for preserving, repairing, and building up skeletal muscle protein is a high-grade protein.

Consuming such items as low-fat dairy products, lean meats, eggs, and whey protein are highly beneficial as they provide essential amino acids which act as the most effective stimulus of Muscle Protein Synthesis (MPS). Whey protein is rated higher than soy according to a grading system, and in comparison to casein, soy is more successful in stimulating protein formation.

Whey is the most well-known type of protein powder and accounts for 20% of the protein found in milk. It is easy to digest and is quickly absorbed into the body.

The reputation of whey has grown thanks to its elevated levels of leucine, a branch chain amino acid (BCAA). Leucine has been labelled the anabolic activator which causes the body to repair and build muscles in response to exercise.

Cow’s milk protein is mostly comprised of casein, which is slowly absorbed, harder to digest and has a lower leucine content. As such, whey is the more advantageous option to consume after a workout.

Plant Proteins

Many proteins derived from plants are labelled as “inadequate” because they are devoid of some of the nine essential amino acids. Exceptions to be noted are powders made from soy, pea, and hemp proteins, which provide all the vital amino acids, although the amount of leucine contained is lower than is seen in whey.

You can get enough of your protein requirement if you have plant proteins of various types in larger amounts. The optimal approach when pursuing this healing process is to blend various vegetable proteins.

Protein Supplement

Athletes are often tempted by the promise that supplements can be a magical solution to all their problems, more so than simply eating nutritiously. Let’s face it, there is such a great amount of selections out there that it is hard to filter through them all, particularly those with protein from multiple sources.

It is essential to consider when to use protein supplementation, yet it is also important to remember that the timing of when to consume protein is essential.

Picking the Best Protein Powder

Generally, it is preferable to source your protein from diet sources, such as animal or plant food, nevertheless, when you are in a hurry, the convenience of protein supplementation should not be overlooked.

Many athletes turn to protein powder for ease of use and to make sure their diet contains enough.

It’s quick and easy to make, suitable for bringing on the go, can last at room temperature for a whole twelve months, and is generally cheaper when weighed against each other. It is important to be knowledgeable about the different types of protein powder, even though it is necessary to not compromise quality.

Whey protein isolate

It has 90% protein and is the least processed, but it also costs more and has a lower lactose content.

Whey protein concentrate

It consists of 30-80% protein and also has some lactose and fat. Furthermore, it is the most inexpensive variant of whey.

Whey hydrolysate

Whey protein that has been pre-processed so that it is absorbed faster, though the most processed of all whey proteins, has an unpleasant flavour and is the most costly. Best for sensitive stomachs.

Casein protein

The best way to repair and build muscles overnight or to fill any gap between extended meals is to snack on healthy foods. Although harder to absorb than whey protein, the so-called “slow” digesting protein can prove to be a challenging nutrient to process. Found in dairy sources.

Soy protein

A great way to get top-notch plant-based protein, a great choice for vegetarians and vegans.

Pea and Hemp Protein

A full-fledged plant-based protein that is beneficial for those on vegan, vegetarian or any other restrictive diets due to an allergy or sensitivity towards whey or soy. Most protein powders contain 20-25g of protein per scoop. Keep in mind more is not better.
