This new research, using state - of - the - art methodology, builds on an earlier publication reporting that a soy - dairy blend extends muscle protein
synthesis when compared to whey alone, as only the blended protein kept
synthesis rates elevated three to five hours
after exercise.
After a turkey meal, blood levels of tryptophan rise, which may amplify the pineal's production of such serotonin, but not melatonin, whose
synthesis rate depends on the amount of enzymes available for the subsequent biochemical reactions to occur, Wurtman says.
However, in the next 28 hours
after the workout, both groups experienced similar lasting elevations in muscle protein
synthesis rates without any significant differences.
The results showed that the five - minute rest group had a much greater
rate of muscle protein
synthesis in the first four hours
after training, while a certain level of anabolic pathways reduction was determined in the one - minute rest group.
However, most types of resistance exercise will accelerate protein turnover (an increase in the
rate of protein
synthesis and breakdown), which is going to increase calorie expenditure in the hours (and, in some cases, days)
after exercise.
Co-ingestion of carbohydrate and whey protein increases fasted
rates of muscle protein
synthesis immediately
after resistance exercise in rats.
To optimize and expedite the recovery process, athletes need to rehydrate and replenish lost stores, with a goal of repleting 100 - 150 % of body mass losses within one hour of exercise cessation (side note: repleting 150 % may be hard on the stomach for heavy sweaters).1 Endurance athletes especially should replenish with water, sodium, and carbohydrate within the first hour
after exercise to ensure the highest
rates of glycogen (our stored energy) resynthesis.15 Recovery drinks with protein have been reported to maximize protein
synthesis rates, consisting of approximately 0.2 — 0.4 g / kg / h protein and 0.8 g / kg / h of carbohydrates.16 Chocolate milk has a nice carbohydrate to protein ratio of 4:1 and is an inexpensive, but still palatable, recovery option.17
Now, if you go into a workout several hours
after eating, you're letting that machinery remain inactive even longer, and if you wait too long to eat
after the workout, breakdown
rates will exceed
synthesis rates, which results in muscle loss.
Besides the mental aspect that being flat has on a competitor, the real problem is that having a flat muscle over time will lower protein
synthesis and the
rate of recovery for the muscle
after a workout is less than what it could be by replenishing the muscle with glycogen.
Ingestion of approximately 20 g protein during and / or immediately
after exercise is sufficient to maximize post-exercise muscle protein
synthesis rates.
More interestingly, another study indicated that citrulline malate supplementation increased the
rate of oxidative ATP production during exercise by 34 %, and increased the
rate of phosphocreatine recovery
after exercise by 20 % - indicating a large contribution of CM towards ATP
synthesis and energy production.
After a workout, the
rate of muscle protein
synthesis has to be greater than the
rate of muscle protein breakdown (MPB).
Myofibrillar muscle protein
synthesis rates subsequent to a meal in response to increasing doses of whey protein at rest and
after resistance exercise
Furthermore, it has been demonstrated that postexercise muscle protein
synthesis rates increase more with the ingestion of greater amounts of protein, reaching maximal stimulation
after ingestion of ∼ 20 g of protein (39, 40).
