The Anabolic Window: Do You Really Need A Post Workout Protein Shake?
A pro Rugby player wrote recently that diet is key to training, supplements are secondary. David on January 7, at Whey protein does not enhance the adaptations to elbow flexor resistance training. I was benching and now I bench This is pretty much on point. For a lb man, this is about g of protein per day.
David on December 14, at 6: While some studies found a slight benefit, others found a bigger benefit from consuming a pre-workout meal. They have to hit your stomach and be digested etc. If you want to perform at your best, get stronger, and build muscle, then you want to make sure your glycogen stores are full before every workout. This is true and another reason why getting protein and carbs in immediately post-workout is not needed. Unlike other products backed by nothing but marketing hype and steroid-bloated professional bodybuilders, Monster Mix is backed by university research.
My Bro goes to the gym and drinks protein shakes. His diet sucks though. A pro Rugby player wrote recently that diet is key to training, supplements are secondary. Nothing to suggest that shakes etc. I came across this article by doing a search on the postworkout meal myth. My problem was this: This is pretty much on point.
If you believe in the PWO shake so much than by all means continue to drink it. But I have a question. Here is the link: Hey Bob, the problem is that nothing is black and white when it comes to the specifics of much of exercise science, including muscle protein synthesis.
For every study that concludes one thing, there will be another study that concludes the opposite. Doing this will likely drive you crazy — and most likely have a negligible difference on your actual results. Anthony has a point David. I included them to let you know I exhausted all possible venues to see if there would be a benefit to this type of post-workout nutrition.
Even when including those studies, there is no evidence. This is interpreted from the muscle building perspective but it sounds like it applies to just recovering your muscles in sporty type activities. I mean going for an mtb ride in the morning and then doing BJJ in the evening and then the next day doing strength training for example.
When your aim is to just recover to do very strenuous activities does the same principle apply to restoring your muscles as it does to growing your muscles? In all articles that talk about magic windows and nutrient timing one tiny tiny factor is always missed. They have to hit your stomach and be digested etc. A process that takes time and is different for everybody.
Today you will still be digesting heavy proteins from yesterday. So much for the magic 30 minute windows where you have to get that brotein shake down your gullet ASAP otherwise your muscles will shrink and your next workout will suck.
Same with spiking insulin with fast carbs. There may be a slight benefit if using creatine but the main part of the theory came from pro bodybuilding where insulin abuse is rife.

Mike on August 21, at David on August 21, at 2: Steve on December 14, at 5: David on December 14, at 6: Hey Steve, This is true and another reason why getting protein and carbs in immediately post-workout is not needed.
RevLifestyleDesign on December 18, at 5: This, however, does not mean that the amino acids have to be consumed immediately after exercise. Due to digestion rates, a meal consumed hours before a training session can still provide the amino acids necessary to initiate post-workout muscle protein synthesis.
The consumption of whey protein, carbohydrates, or even a mixed meal after a workout has been shown to elevate insulin levels well above baseline. It is shown to decrease muscle protein breakdown by up to half! This is a very good reason to consume a protein shake and eat a meal post-workout. Insulin levels would stay elevated after training even if you consumed the shake before or during your training session, giving you enough time to get home and eat a whole food meal.
Some studies show amino acids and carbohydrate consumed prior to exercise do a better job of inducing an anabolic response in muscle than the same supplement consumed after exercise. One study showed that 20g of whey protein delivered pre-workout increased amino acid uptake by the muscles during and up to 3 hours after the training session.
In a very recent, and beautifully designed study, Brad Schoenfeld and colleagues showed that supplementation of 25g of protein with 1g of carbohydrate before resistance training had the same effect on muscle thickness, body composition AND maximal strength. The study was one of the first to look at whether the acute effects of nutrient timing were significant over the course of a week weight training cycle. The study compared the effect of a roughly 34g carbohydrate, 32g whey protein, and 5.
The group who consumed the supplement immediately before and after their workout gained significantly more lean mass and strength, while also losing body fat. As you have probably gathered, the jury is still out about whether or not consuming a shake within one hour AFTER training actually provides any real advantages when it comes to muscle strength, size, and performance.
Based on the research that is relevant to strength athletes, it is apparent that consuming protein and carbohydrates around your training session will lead to positive adaptations in the long run. If a protein shake immediately post-workout is already a part of your routine, there is no reason to stop. It is certainly not hurting you. One lesson you can take away from this research is not to neglect your pre-workout nutrition just because the post-workout window has been put on a pedestal.
There is plenty of evidence that sandwiching your workout with protein, carbohydrate, and even creatine is worth your while. If your workout is very strenuous, your electrolytes will be out of whack. After your workout, your body goes into a brief state where it is able to both compensate for the damaged muscle and depleted glycogen stores and spike protein synthesis, ultimately creating new, lean muscle mass that would otherwise not be possible. As it turns out, research shows actual protein breakdown in muscle tissue is only very slightly raised after a workout.
There is one notable exception, however: If you wake up and hit the gym without eating breakfast, for instance, evidence shows that your muscle protein breakdown will be markedly increased, making an immediate post-workout protein shake along with some simple carbs very important.
The most current and methodically sound studies, however, suggest that while maintaining adequate protein intake over a 24 hour period is important for making gains, immediate post-exercise protein intake is not necessary in order to reap the benefits of your workout.
Aragon and Schoenfeld found that overall, existing research which included the young, the elderly, fit people, obese individuals and those who do not habitually workout did not demonstrate a heightened need for protein intake immediately post-workout. To add to that, Aragon and Schoenfeld also noted that glycogen repletion another benefit touted as exclusive to post-workout protein shakes , while important over a hour period, is not necessary immediately post-workout. This experiment compared increases in muscle volume between two groups of young men, one of which was a placebo group while the other had protein supplementation.
This study controlled for both habitual protein intake and level of training, and found that supplementation post-workout did not augment either muscle strength or size relative to the placebo group.
Failure to replenish lost electrolytes post-workout can result in dizziness, nausea, confusion, and muscle weakness, spasms, and cramps.

Get Social With BarBend. Helps ensure smaller protein peptides are formed, which helps maintain normal CRP levels.
These supplies are expected to sell out quickly, so we recommend you reserve your supply NOW. Across all the studies, groups that gorged on protein immediately after exercise fared little better than those who simply ate the same amount of protein throughout the day.
I went from to Studies have shown the availability eorkout amino acids after resistance exercise has a greater effect on maximizing muscle protein synthesis than carbohydrates or placebo alone. It is possible that new athletes simply benefit from any increase in training and protein consumption, but experienced athletes may have to time protein consumption to maintain steady gains. Effect of timing of ingestion of high glycemic index food. The study was one trenbolone kullan?m? the first to look at anabolic post workout shake the acute effects of nutrient timing were significant over the course of a week weight training cycle. Some studies have shown protein consumed anabolkc post-workout is more effective at stimulating muscle protein synthesis and hypertrophy than delaying anabolic post workout shake even a few hours.
