What is the effect of prolonged sitting on muscle function?

Prolonged sitting significantly impacts muscle function, most notably by leading to muscle atrophy. When the body remains in a seated position for extended periods, certain muscle groups, particularly the glutes and hip flexors, become underused. This lack of engagement can result in a reduction in muscle size and strength, as the muscles do not receive the necessary stimulation for maintenance and growth.

Additionally, prolonged sitting can contribute to poor circulation and decreased inflammatory response in the muscles, further exacerbating the atrophy process. Thus, the correct understanding of this phenomenon is crucial for developing effective strategies to counteract the negative effects of a sedentary lifestyle, such as engaging in regular movement or exercise routines that activate these muscles to maintain their function and health.
