Protein ingestion after exercise stimulates muscle protein synthesis (the main process regulating muscle recovery, adaptation and growth). It has been well established that protein intake improves resistance training adaptations.
2/
However, little is known about the impact of protein on muscle adaptations following endurance exercise.
3/
We investigated the impact of 15, 30, and 45 g of milk protein ingested post endurance exercise in trained cyclists. Both myofibrillar (contraction) and mitochondrial (energy production) protein synthesis were measured.
4/
The endurance exercise session consisted of 1.5 hours of cycling on 60% of the maximal wattage of the subject.
5/
None of the protein doses stimulated mitochondrial protein synthesis rates.
6/
15 g of milk protein was not enough to significantly stimulate myofibrillar protein synthesis after cycling exercise. However, both the 30 and 45 g protein stimulated myofibrillar protein synthesis after cycling, with no significant differences between the doses.
7/
Statistical analyses showed that ~0.49 g/kg was the optimal dose.
8/
In conclusion, 30 g of milk protein gives a near-maximal stimulation of muscle protein synthesis during recovery from endurance exercise.
Protein distribution: beneficial, detrimental, or inconsequential?
Our response to commentary.
❌Not eating =/= fasted state
🥩Protein amount vs protein distribution
✅Practical recommendations
A 9-part thread. 🧵👇
The concept of protein distribution suggests that how you distribute your meals throughout 24 hours strongly impacts your overall anabolism.
There are contrasting lines of thought of what meal frequency is preferred for various health or athletic outcomes.

In intermittent fasting or time-restricted feeding, food is consumed in a relatively short feeding window.
The goal is to be in a fasted/catabolic state, which is believed to be healthy. For example, it is thought to speed up the removal of damaged proteins (autophagy).
The ketogenic diet restricts carbohydrates with the purpose of lowering insulin levels. Insulin is a hormone that is involved in fat metabolism. Therefore, some suggest that a ketogenic diet is very effective for fat loss.

This study investigated whether a ketogenic diet increases fat loss compared to a high-carbohydrate diet in overweight and obese men.

Pre-sleep Protein Ingestion Increases Mitochondrial Protein Synthesis Rates During Overnight Recovery from Endurance Exercise: A Randomized Controlled Trial
Prostate cancer is one of the most common types of cancer. An effective treatment is androgen deprivation therapy (ADT), which lowers testosterone levels to castration levels. However, such low testosterone levels tend to result in a loss of muscle mass and strength.
2/
Our study investigated the effect of resistance training with or without protein supplementation on muscle mass and strength in prostate cancer patients undergoing ADT.
Exercise and protein ingestion are the main factors that stimulate muscle protein synthesis (the main process driving muscle adaptations such as growth).

It has been reported that athletes are more likely to consume excessive amounts of alcohol, especially as part of binge-drinking practices in team sports. Can these practices affect muscle protein synthesis?
