lihasepump

Lihaspump, also known as the muscular pump or muscle pump, refers to the temporary increase in muscle size experienced during and immediately after resistance exercise. This phenomenon occurs when blood flow to the working muscles increases significantly to deliver oxygen and nutrients, and to remove metabolic byproducts. The increased blood volume engorges the muscles, causing them to swell and appear larger. This swelling is largely due to the accumulation of fluids, including blood and intracellular water, within the muscle tissue.

The sensation of the muscle pump is often described as a feeling of tightness and fullness in the muscles. While it is a temporary effect, many individuals find the visual and sensory experience of the muscle pump to be motivating and rewarding. Some research suggests that the muscle pump may contribute to muscle hypertrophy, the process of muscle growth, by stretching the sarcolemma, the muscle cell membrane. This stretching is hypothesized to trigger signaling pathways that promote protein synthesis and ultimately lead to an increase in muscle size over time. However, the precise mechanisms and the extent to which the muscle pump contributes to long-term muscle growth are still subjects of ongoing scientific investigation. Factors such as the type of exercise, the training volume, and the individual's hydration status can influence the intensity and duration of the muscle pump.
