1. Chase the Pump
Arnold was a big proponent of training for "the pump." The pump is a phenomenon whereby muscles become engorged with blood following resistance training. It's primarily achieved by performing multiple sets with moderate to high reps.
Here's the short course: During a moderate rep set, the veins taking blood out of working muscles are compressed by muscular contractions. However, the arteries continue to deliver blood into the muscles, creating an increased amount of intra-muscular blood plasma. This causes plasma to seep out of the capillaries and into the interstitial spaces (the area between muscle cells and blood vessels).
The buildup of fluid in the interstitial spaces along with the osmolytic properties of lactate creates an extra-cellular pressure gradient, which in turn causes a rush of plasma back into the muscle. The net result is that blood pools in your muscles, causing them to swell. Researchers refer to the pump as cell swelling.
This is what Arnold had to say about the subject in the immortal movie, Pumping Iron: "The most satisfying feeling you can get in the gym is 'the pump.' Let's say you train your biceps. The blood is rushing into your muscles. Your muscles get a really tight feeling, like your skin is going to explode any minute. It's like somebody blowing air into your muscles. There's no better feeling in the world."
Although many consider the pump a temporary condition that's strictly cosmetic, this belief may be shortsighted. Studies have demonstrated that a hydrated cell stimulates protein synthesis and inhibits proteolysis (protein breakdown).
Understand that muscle hypertrophy is ultimately a function of protein balance – synthesize more muscle proteins than you break down and you'll pack on size. The fact that cell swelling simultaneously increases synthesis while reducing degradation is a muscle-building home run!
What drives this swelling-induced hypertrophic response? Increased fluid in muscle fibers causes a stretch of the cell membrane, like an overinflated water balloon. The muscle, in turn, perceives this as a threat to its integrity and responds by initiating an anabolic signaling cascade that ultimately serves to reinforce its ultrastructure.
Unfortunately, no direct studies have attempted to investigate whether these anabolic effects are attained from pump-oriented training. Still, the implied evidence gives reason to believe that it very well may have a positive affect on muscle growth.
Usually targeted movements that keep constant tension on the muscle induce the pump. The occlusion and hypoxia created from "chasing the pump" has been shown to lead to a long list of hypertrophy-boosting mechanisms, and one of these includes increased satellite cell activity, which also increases the muscle cell's ability to continue expanding.
Bottom line is, if muscle development is the goal, don't be afraid to incorporate some 'pumping' sets into your routine.
מה זה פאמפ אתה יודע?
פאמפ זה מצב שבו לשריר מוזרם דם עקב כך שאתה מתאמן על אותו שריר ברגע הנתון שאנו מדברים עליו כלומר האימון.
עקב זרימת הדם לשריר השריר נראה גדול יותר אך כאמור לאחר האימון השריר חוזר למצבו הנורמלי.
שריר גודל כאשר אתה עובד עליו נכון(בהנחה שאתה עובד עליו נכון אני לא אתחיל לפרט כאן איך ומה לעשות מאמין ומקווה שאתה יודע) וכאשר באימון הסיבים האדומים נקרעים והם מתחדשים על ידי התאוששאות אוכל וכו...
כשאר הם מתחדשים הם גודלים דבר הגורם לשריר לגדול
