But what actually goes on during a pump? .. 💪🏾Pumps are the result of metabolic byproducts of muscle contraction, increased blood flow to a muscle group, increased water, and decreased blood flow away from a muscle group. When you performhigh reps, your body produces metabolic byproducts like lactic acid. .. 📲Download My Workouts Directly To Your Phone At Trainwithkai.com Or Click The Link In Bio .. 🧬Your body needs to shuttle these byproducts away, so it sends increased blood flow to that area. That blood is pumped into your muscles. However, that same blood is constricted from leaving by the contracted muscle group. Therefore, the blood pools in your muscle group to create a pump. These pumps can cause cellular fatigue wherein your muscles can no longer contract as forcefully. This translates to something known as cellular swelling. .. 🌡Cellular swelling is increased by supersets and it signals the muscle to increase protein synthesis and decrease protein breakdown, there by growing more dense muscle tissue.」9月9日 12時55分
