The intricate relationship between the fascia and muscles in the human body plays a fundamental role in human mobility. This connection, referred to as the myofascial system, significantly influences the efficiency and fluidity of movement, posture, and alignment. This paper will explore the current understanding of the relationship between fascia and muscles and its effect on human mobility.
The Myofascial Continuity
Thomas Myers in his book, “Anatomy Trains,” illustrates the concept of myofascial continuity, highlighting that the muscles in the human body are interconnected through a web-like network of fascia. Myers explains that these lines of pull or “myofascial meridians” distribute strain, transmit force, and affect the structure and function of the body, enhancing the efficiency and fluidity of movement (Myers, 2014).
Biomechanical Energy Storage and Release
The fascia’s viscoelastic properties play a pivotal role in enhancing the fluidity of movement. Schleip et al. (2012) describe how the fascial system acts like a biological spring. In activities such as running and jumping, the fascia lengthens and stores mechanical energy during the landing phase. It then shortens and releases this stored energy during the push-off phase, augmenting muscle power and conserving energy. This process, known as the stretch-shortening cycle, significantly enhances the efficiency and fluidity of movement.
Fascia as a Sensory Organ
Findley and Schleip (2009) highlight the importance of fascia as a sensory organ. The fascial network is rich in mechanoreceptors, including Pacinian corpuscles and Ruffini endings, making it highly responsive to changes in mechanical pressure and tension. The sensory information from these receptors is continually relayed to the central nervous system, providing feedback that facilitates real-time adjustment of muscle activity and movement coordination, enhancing movement fluidity and efficiency.
Fascia and Postural Control
The fascia plays a pivotal role in postural control. Carla Stecco’s work on the fascial system, as outlined in her book “Functional Atlas of the Human Fascial System,” emphasizes the importance of the fascia in maintaining the body’s structural integrity. The continuous tensional network of the fascia assists in distributing mechanical forces across the body, contributing to the maintenance of posture and alignment (Stecco, 2014).
Fascial Densification and Compensation
Fascial densifications, or areas of increased tension, can result from chronic poor posture, repetitive movements, or trauma. These densifications can lead to compensatory changes in posture and alignment, as the body attempts to maintain balance despite the increased local tension. Over time, these changes may contribute to chronic pain and reduced mobility (Stecco, 2014).
Mechanotransduction and Fascial Remodeling
Helene Langevin’s research explores the concept of mechanotransduction and its role in fascial remodeling. Chronic mechanical stress, such as that from poor posture, can lead to fibrosis or thickening of the fascial tissues, disrupting the body’s alignment and potentially leading to chronic pain conditions. Understanding the process of mechanotransduction provides insights into the long-term impacts of mechanical forces on posture and alignment (Langevin et al., 2011).
In summary, the interaction between the fascia and muscles plays an indispensable role in human mobility, contributing to the efficiency and fluidity of movement, and the maintenance of posture and alignment. Appreciating this interaction can enhance our understanding of movement and posture control and inform therapeutic strategies for movement-related disorders.
