Postural muscles are those that maintain our posture, keeping us on our feet and helping us oppose gravity. They are constantly active, even during normal activities and at rest, and have a higher resting tonus and readiness to act. Postural muscles are influenced by the nervous system, which regulates reflex control of the spine and posture. Maintaining good posture is important for health, as poor posture can increase pressure on the spine, induce breathing disorders, and affect the heart and phrenic nerve. Certain exercises like yoga and tai chi can help improve posture, as can maintaining a healthy weight and wearing comfortable shoes. Understanding the function and characteristics of postural muscles can help trainers develop effective training programs for their clients.

Postural muscles are constantly active to help us oppose gravity and keep us on our feet
Postural muscles are a group of muscles that are constantly active and help us oppose gravity and keep us on our feet. They are essential for maintaining our posture and balance, ensuring we remain upright and stable. The ability to maintain balance and posture is known as postural control, which is influenced by the interaction between the individual, the task, and the environment.
Postural control is achieved through the activation of various muscles in the body, including the soleus, gastrocnemius, tibialis anterior, gluteus medius, iliopsoas, erector spinae, and abdominal muscles. These muscles work together to counteract gravity's pull and maintain our stability. The constant activity of postural muscles contributes to their higher resting tonus and readiness to act.
The concept of postural and phasic muscles was developed by Dr. Vladimir Janda, a Czechoslovakian physiatrist and physiotherapist. Phasic muscles differ from postural muscles as they are not responsive to gravity and are activated on demand. While postural muscles are constantly active, phasic muscles exhibit a pattern of weakness and inhibition, sometimes even mimicking paralysis.
Postural muscles are particularly important during the gait cycle when we are standing on one foot. Maintaining good posture is crucial for overall health and well-being. Poor posture, such as prolonged slouching or slumping, can increase pressure on the spine, induce breathing disorders, and affect surrounding structures like the heart. It is important to note that any exercise can help improve posture, with specific practices like yoga and tai chi being particularly beneficial.
Understanding the relationship between postural and phasic muscles is essential for developing effective training programs. Trainers can utilize this knowledge to create exercises that support the body's natural bipedal stance and help individuals achieve their fitness goals. By focusing on the unique characteristics and interactions of these muscle groups, trainers can enhance their clients' function, posture, and overall well-being.

Postural muscles are involved in the bipedal challenge, which is walking on one leg for most of the time
Postural muscles play a crucial role in maintaining balance and stability, especially during the bipedal challenge of walking on one leg. This challenge is inherent to human movement and requires the coordinated action of multiple muscle groups. The bipedal challenge, or "bipedal stance," refers to the unique ability of humans to stand and walk on two feet, a trait shared by no other creature on Earth.
Postural muscles are those that exhibit tonic or anti-gravity behavior. They are constantly active, working to oppose gravity and keep us upright and balanced. This constant activity results in postural muscles having a higher resting tonus and a shorter-than-average resting length. They are essential for maintaining posture, which is the body's attitude or alignment, achieved through the coordinated action of many muscles working together to keep us stable.
The bipedal challenge is a complex task that requires the integrated functioning of all body musculature, including the limbs, trunk, and neck. The trunk, in particular, plays a pivotal role in maintaining balance during locomotion, as it represents 50% of the total body mass and houses the center of gravity. This center of gravity is constantly in motion, even during seemingly static activities like breathing.
The nervous system plays a critical role in regulating posture and movement. It activates the myo-connective tissues and skeleton, allowing for the cyclic movements necessary for locomotion. Additionally, the vestibulospinal tracts, originating in the vestibular nuclei, enable rapid postural adaptations by modulating motor neuron activity. This helps the trunk and extremities adjust to changes in head position, maintaining stability.
Understanding the relationship between postural and phasic muscles is essential for developing effective training programs. Phasic muscles, unlike postural muscles, are not responsive to gravity and are available on demand. Together, they create a "natural, physiologically balanced imbalance" that supports the body's movement and function. By recognizing this relationship, trainers can design exercises that improve clients' function and posture, helping them meet the demands of the bipedal challenge.

Postural muscles are more susceptible to shortening even during normal activities and at rest
Postural muscles are those that are inherently active and help us to oppose gravity and keep us on our feet. They are in constant use, which may contribute to their higher resting tonus, readiness to act, and tendency to have a shorter than normal resting length. This shortening occurs even during normal activities and at rest.
Postural muscles are susceptible to shortening because they are always in use, even when we are just breathing. Standing and walking with the body in good alignment is a nearly effortless process due to the give and take of muscular activity and a finely tuned proprioceptive system. However, this constant activity can lead to postural muscles having a higher resting tonus and a shorter resting length.
The tendency of a muscle to be short or tight is not fully understood, but this pattern of muscle behaviour has been consistently observed. Poor posture, such as prolonged slouching or slumping over, can increase pressure on the spine, induce breathing disorders, and affect surrounding structures including the heart and phrenic nerve. In addition, ageing inevitably affects posture, and extra weight can weaken abdominal muscles, cause problems for the pelvis and spine, and contribute to low back pain.
To improve posture, it is recommended to stay active and engage in exercises that strengthen the core, such as yoga, tai chi, and other classes that focus on body awareness. Maintaining a healthy weight and wearing comfortable, low-heeled shoes can also help to improve posture.

Postural muscles are controlled by the nervous system, which regulates all other bodily systems
Postural muscles are those that maintain our posture. Posture is the attitude assumed by the body either with support during muscular inactivity or the coordinated action of many muscles working to maintain stability. It is an active process involving not only our muscles and joints but also our perception, emotions, and the environment we are in. Even seemingly static positions, like sitting or standing, are full of tiny adjustments and movements.
The nervous system plays a crucial role in maintaining reflex control of the spine and posture. It controls and regulates all other bodily systems, and disruptions to normal nervous system function can contribute to a wide variety of common ailments. The medial and lateral vestibulospinal tracts modulate motor neuron activity, allowing for rapid postural adaptations. The cerebellum collects afferent information from the visual field, the vestibular nerve, and the cervical mechanoreceptors, interpreting this information for the generation of reactive postural corrections.
The vestibulospinal tracts help correct sudden perturbations in static upright posture. While visual input may be more important for constant postural adaptation, the vestibular apparatus, via the vestibulospinal tracts, is much quicker to respond to early or slight postural disruptions, allowing for a faster overall response. The descending control of axial muscles, which are important for posture, originates from a wide variety of cortical and sub-cortical structures, including the somatic brain stem pathways.
The monoaminergic descending systems also regulate muscle tone, with fibres originating from various nuclei in the brainstem. The limbic system, another brain structure, also influences postural tone. The axial musculature is architecturally complex, with muscles spanning long distances and having multiple attachments to multiple bones. The descending brain stem pathways provide an important source of control to the axial muscles, which are essential for maintaining posture and stability.

Poor posture can induce breathing disorders and affect the heart and phrenic nerve
Poor posture can have a detrimental impact on your health, including your breathing and heart function. Slumped or forward posture, often caused by looking down at phones or computers, can cause the muscles in the front of the chest to shorten, while the muscles in the back are stretched and weakened. This can lead to a decrease in the space available in the thorax or chest area, which in turn restricts the diaphragm's ability to expand and contract fully. As a result, your cells, heart, and vital organs may not receive optimal levels of oxygen. This can contribute to a range of health issues, as your body and organs are not functioning at their best.
Breathing disorders are a common issue associated with poor posture. The strain on the respiratory system can make it difficult to take deep breaths, reduce overall lung function, and lead to shallow chest breathing. This shallow breathing can further contribute to tension in the neck and shoulders, causing pain and restricting the rib cage's expansion. Over time, this can lead to more serious musculoskeletal problems, such as altered spinal alignment and degenerative spinal conditions. Additionally, poor posture is linked to elevated cortisol levels, which can result in various health issues, including high blood pressure.
The diaphragm is controlled by a nerve called the phrenic nerve, which runs through the neck and lower chest. Damage to this nerve can cause breathing difficulties as it disrupts the function of the diaphragm, making it harder to breathe comfortably. Poor posture can contribute to phrenic nerve issues, as maintaining proper neck and shoulder flexibility is crucial for keeping this nerve in good condition. By practising good posture, you can help ensure the phrenic nerve functions optimally, allowing your diaphragm to work smoothly.
To improve your posture and mitigate the potential impact on your breathing and heart health, it is essential to be mindful of your sitting and standing positions. Sitting or standing tall can provide more space in your thoracic cavity, allowing more oxygen to enter your bloodstream with each breath. Additionally, arranging your workspace to ensure your computer screen is at eye level can help prevent forward head posture. Regular stretching and massage can also positively impact your posture and cardiovascular system, reducing tension and increasing blood flow, which lessens the burden on your heart.
