Protein for athletic power and strength -
Protein is a macronutrient found in bodily structures such as bone, skin, hair, and particularly muscle. Protein helps to rebuild and repair our muscles.
Good sources of protein are foods such as eggs, poultry, turkey and chicken fish and lean cuts of beef, low-fat dairy milk and yogurt beans and soy products. The recommended daily allowance for a sedentary adult is 0. However, many studies have demonstrated that strength athletes who engage in rigorous exercise require higher protein intakes due to the muscle damage that occurs as a result of the exercise.

Many of those reading this will be aware of the general recommendation of 1 gram g of protein per pound lb of body mass However, it can be challenging to determine the specific protein requirements for athletes, as many factors can change the advised ranges.
Whether it is training status, individual sport, or dietary intake, many factors can influence recommendations for protein intake for athletes. Most data discussed in this article will deal with studies that used nitrogen balance to assess adequate protein requirements.
From a physiological standpoint, to be in nitrogen protein balance means that protein nitrogen intake is equal to protein nitrogen loss While nitrogen balance is an accepted measure for assessing protein requirements, it has some drawbacks, which might result in recommendations that are too low Along with nitrogen balance and protein quantity recommendations, it is also vital to keep a note of the quality of protein athletes are ingesting.
Protein Type and Quality As many protein types exist, there is a range of protein quality and completeness that needs to be addressed when it comes to protein requirements Milk proteins whey and casein are typically rated as two of the highest qualities of proteins available while varying plant sources usually score the lowest Protein sources from eggs, beef, poultry, fish, and dairy are regularly viewed as excellent sources of protein A protein source with all of the essential amino acids in the correct amounts and proportions to increase muscle protein synthesis is known as a complete protein Dietary protein sources of animal origin are broadly classified as complete protein sources, while sources of plant origin are commonly missing one or more of the essential amino acids and must be combined with complementary incomplete protein sources The current recommended dietary allowance RDA of protein is 0.
However, a more recent analysis of the same data notes a value of 1. Also, further analysis of daily requirements for sedentary adults using a more accurate amino acid analysis technique Indicator Amino Acid Oxidation found a value of 1. So overall, there exists a range in the literature when it comes to sedentary adults 0.
This should be the absolute bare minimum that athletes ingest daily, but as athletes require more than the typical sedentary adult, read on to the next sections to determine individual needs based upon various situations. Endurance athletes are no different; protein requirements vary depending upon training status, exercise intensity, workout duration, and dietary intake The best way to approach these variations is to classify athletes as recreational athletes those predominantly performing low- to moderate-intensity endurance exercise , modestly trained athletes, and elite endurance athletes Multiple studies have found that a recreational level of endurance training does not alter the amount of protein needed for that athlete 31, One such study by el-Khoury et al.
For modestly trained athletes, multiple studies have reported protein intakes of 0. These protein intakes resulted in net negative protein balances following exercise.
Recommendations of In terms of elite endurance athletes, a small collection of studies has examined their protein requirements. One found that 1. Another advised that 1. A further study by Brouns et al. If an endurance athlete is interested in improving their endurance exercise performance, diets high in protein appear to offer no benefit.
Still, they may help reduce psychological stress and declines in performance commonly seen during blocks on high-intensity training And ingestion of protein following resistance exercise is required for a positive protein balance Regular resistance exercise is also a source of stress and trauma that requires greater protein availability to recover A meta-analysis involving participants across 22 published studies has also demonstrated a positive impact of protein supplementation on improvements in fat-free mass and leg strength when compared to a placebo in both young and old populations 8.
An example of this is the near-universal finding of untrained or unaccustomed individuals needing increased amounts of dietary protein. Tarnopolsky et al.
They concluded that the lowest intake compromised protein synthesis when compared to the moderate and high intakes and that while the moderate protein intake amounted to a neutral protein balance, they recommended one standard deviation above at 1.
Other studies have also suggested that protein intakes ranging from 1. The International Society of Sports Nutrition ISSN has also published position statements on the protein requirements of athletes, and they note 1. And a consensus statement from ACSM et al.
A fascinating and recent study was a systematic review, meta-analysis, and meta-regression by Morton et al. Data from the review, including 49 previous studies and participants, showed that protein supplementation significantly improved fat-free mass gains, maximal strength, muscle fibre diameter, and cross-sectional area of femur thigh mass The authors also noted that a protein intake higher than 1.
Two other studies by Antonio et al. Their first intervention had 30 resistance-trained individuals continue following their typical exercise training program alongside either a control or high-protein diet 4. While the 30 participants were at a caloric surplus for 8 weeks, no changes in body mass, fat mass, fat-free mass, or per cent body fat were found when compared to the control group.
The participants followed either their normal diet of 2. Ultimately, the researchers found similar changes in strength, and the control group saw a significant increase in body mass. In contrast, the high-protein group saw a greater decrease in fat mass and per cent body fat 3.
They theorised that those changes in fat-free mass they saw in both of the groups were the result of a different training stimulus. Intermediate Strength Athletes 6 months — 2 years training : 1.

Protein intake of 1. Protein intake at this level is not detrimental to kidney function or bone metabolism in healthy, active persons when part of a balanced, nutrient-dense diet.
Daily protein requirements can be met through a varied, regular diet. Supplemental protein, e. protein powders, are a practical way of ensuring adequate and quality protein intake for athletes.

It will take 20 calories just to break down the 70 grams of protein. It will be used. Higher protein diets lead to more lean individuals.
Compound movements need more protein intake than isolation movements. Training age has an impact on recovery and the amount of protein needed to get swole.
We also know that eating other macronutrients increases an anabolic response if we eat a higher amount of protein. Having carbs and fats in there will improve our anabolic response. We also know that muscle protein synthesis and muscle protein degradation play on a see-saw.
With training, we have to start with the idea that training age matters. An elite athlete needs more protein. A young athlete, I recommend, 1.
A well-trained athlete probably needs 2. Supplementing and meals bring us into the training age discussion again. For elite athletes, who recover quicker, it is probably easier to have them consume whey protein with raw milk to partition the protein quickly.
Removed from that time period, later on, 3 to 4 hours later, they need to have a large meal with carbs, fats, and a large amount of protein to increase and lengthen muscle protein synthesis to increase the anabolic window. Using that upper confidence interval, that is about.
Weighing kilos means eating grams of protein per meal over the course of four or five meals. That is for anyone with a resistance-based training background. A not as well-trained athlete will be closer to. So a kilo athlete who is not as well trained to get swole AF needs to consume about 40 grams of protein per meal throughout the day.
The body will use the protein. The important takeaways are knowing the three different types of hypertrophy and how they impact muscular growth. We can then break it down by understanding training age and the impact of compound movements and isolation movements.
From there, we can start to think about consuming other macronutrients with a large amount of protein to help how the body responds. Newbies, 1. Well trained, 2. How to Get Strong AF. Are Calisthenics Better Than Weight Training? How to Build Athletic Muscle.
