It's time to talk about what to eat, and when. There are three times for increasing protein/amino acid availability to augment the acute increase in protein synthesis caused by training: Pre-workout: Within an hour or so before the workout begins. Peri-workout: During the training session. Post-workout: Less than two hours post-exercise. The 10,000 dollar question is, which time(s) are best to get the maximum growth response from your training? Scientists have looked into this, and the results of way several studies are shown in the figure below. The take-home from this chart is that post-workout nutrition amplifies the acute, exercise induced increase in protein synthesis more than pre-workout nutrition. This is good information to know, but there's much more to this story. Pre-workout, during training, atp is burned to fuel muscle contractions, which increases amp levels.
Mtor is arguably the most important cell signaling complex for muscle growth. It's the master-controller of protein synthesis in pdf the cell, and there's a direct relationship between muscle growth and mtor activation; the more a workout activates mtor, the more the protein synthesis machinery cranks out new proteins for muscle growth and repair. Mtor is activated by three things: Mechanical stress (from heavy training loads). Growth factors (igf, growth hormone, insulin, etc.). Amino acids (particularly leucine the "Anabolic Window so what can we do nutritionally to accomplish more than simply replacing the muscle you've just broken down in the gym with an equal amount to build back up? You take advantage of the. To get as big as possible you must exploit the window for maximal effect.
You can see how this works in the figure below. Without a training stimulus, muscle protein synthesis and muscle protein breakdown cancel each other out. But add in an intense training session with the right nutrient intake at the right time and things change; protein synthesis is activated and degradation is suppressed. The result is an accumulation of muscle protein over time, as shown in the figure below. Protein Synthesis Primer: It's all about mTOR. To understand protein synthesis, it's important to become better acquainted with mTor. Research tells us that when you force a muscle to contract against a heavy load, the primary response is an activation of protein synthesis. Protein synthesis activation is, in turn, controlled by a series of phosphorylation events orchestrated by a protein called mammalian target of rapamycin, or mtor for short.
Reagents and, methods for Assaying, protein, synthesis
After the complex contains mrna and initiator fmettrna, the following things occur: gtp is hydrolyzed to gdp, the initiation factors are released from the ribosome, and the 50S subunit associates with the complex to form an elongating ribosome, as shown in Figure. Want to know the long-lost secret to muscle growth? Npb mps mpb, so what does this equation mean? Net Protein Balance (skeletal muscle mass, for our purposes here). Muscle Protein Synthesis, muscle Protein Breakdown. Make it a positive value and you're on your way to hugeness.
Remodeling Muscle, you have to eat right to build your muscle tissue back up after destroying it in the gym. Under normal conditions, skeletal muscle has a high turnover rate in the range of 1-2 of muscle proteins are being synthesized and broken down daily. Both training and nutrient intake are potent activators of protein synthesis, although nutrient-induced increases are short-lived. Training has a bigger effect; protein synthesis is ramped up for 24 hours in trained people. The problem is that training also activates muscle protein degradation. Without the right nutrition at the right time, any potential muscle gain from increased protein synthesis could be canceled resume out by protein breakdown.
A further basepairing event between noncoding regions of mrna and rrna is required to select the proper reading frame and initiation codon. Bacterial mRNAs contain a purinerich sequence (called a shineDalgarno. Rbs, which is an abbreviation of RibosomeBinding Sequence) in the 5 nontranslated region of the mRNA. This sequence is complementary to the 3 end of the small subunit rrna, 16S rRNA. See figure .
Figure 1, after basepairing is established, protein synthesis starts with the first aug downstream of the rbs. This feature of initiation is used as a form of translational control. Messenger rnas with the greatest degree of rbs complementarity to 16S rrna are translated most efficiently, presumably because they initiate more efficiently. Several protein factors are involved in the initiation process. These factors aren't usually part of the ribosome; instead, they help form an active initiation complex. Initiation factor 3 (IF3) helps keep the 30S subunit dissociated from the 50S subunit and available for protein synthesis. IF1 binds to the isolated 30S subunit and helps form the complex between the rbs and 16S rRNA. IF2 forms a complex with fmettrna metI and gtp, releasing IF3.
Protein, and, life extension
Because rna is synthesized in a 53 thank direction, a bacterial mrna can start translation while the dissertation 3 sequences are still being transcribed. This is important in several forms of biological control. A special initiator trna, trna metI (I stands for initiator) is used for beginning protein synthesis. In bacteria, this initiator trna carries the modified amino acid Nformylmethionine (fmet). The formylation reaction transfers the formyl group from formyltetrahydrofolate to methionyltrna metI. This initiator trna is used to recognize initiation codons; it does not insert met in response to an internal aug codon. As a further safeguard, the formylation reaction ensures that the initiator methionine can only be at the amino terminus of the synthesized protein. The decoding step of protein synthesis involves basepairing between mrna codon and trna anticodon sequences.
The protein synthetic machinery must select the appropriate starting points for mrna reading and peptide bond formation. Aug is usually used as the starting codon, and essentially all proteins begin with a tears methionine. Aug is also the codon for methionine that occurs in the interior of a protein as well, so there must be a mechanism to distinguish between the two types of methionine codons. The steps of initiation occur on the isolated small subunit (30S) of the prokaryotic ribosome. Ribosomes contain two subunits, a 30S and 50S subunit, which associate to form a 70S particle. (The s values refer to the rate at which each component sediments in the ultracentrifuge; they don't always add.) In general, the 30S subunit is mostly involved in the decoding and tRNAmrna interaction process, while the 50S subunit is involved in actual peptide bond. Ribosomal subunits are dissociated prior to the initiation reaction. Translation is initiated at the 5 end of mRNA.
