What are postural muscles?
Postural muscles are also referred to as core stability muscles, are found deep in the body.
The first muscles that typically come to mind with posture are the muscles along the spine. The erector spinae muscles run along the bones of your spine, the vertebrae, from your neck all the way to your tailbone. These muscles hold the spine in extension or upright, counteracting the pull of gravity. Abdominal muscles support the structures at the front of your trunk, balancing the pull of your back extensors. The quadratus luborum muscles at the top of your pelvis help stabilize the pelvis and spine in the lower back in an upright position.
The purpose of postural muscles is to keep good posture in the field of gravity. These muscles consist mostly of slow-twitch muscle fibres and have a greater capacity for prolonged use but are prone to over working. This means if you have poor posture or you have long periods of sitting immobile your postural muscles get tired and they become weak and less efficient. The longer the situation continues the more likely you are to develop postural imbalances and they finally you get knots and pain!

The Impact of Sitting All Day – Part 1
For most people know they sit all day as part of their job. Recently there has been a spate of article in the press about the impact of sitting all day, so I wanted to take some time to look at the impact of sitting all day.
Sit up Straight
I want to start this series of articles on a positive note, as most of my clients have to sit to work, the negative impact of sitting is minimised if you sit correctly. As your Mum always said, "Sit up straight", i.e.- Not leaning forward
- Shoulders relaxed
- Arms close to sides
- Elbows bent 90°
- Lower back should be supported
- Feet flat on floor
So what happens if you don't sit up straight?
As you would expect from a masseur I am going to start by looking at the impact on your muscles.
Strained Neck & Sore Shoulders
If most of your sitting occurs at a desk at work, craning your neck forward toward a keyboard or tilting your head to cradle a phone while typing can strain the cervical vertebrae and lead to permanent imbalances. The neck doesn't slouch alone. Slumping forward overextends the shoulder and back muscles as well, particularly the trapezius, which connects the neck and shoulders. Here at Vitality Therapy we offer Seated Acupressure Massage to directly address these issues.Bad back
When we move around, soft discs between vertebrae expand and contract like sponges, soaking up fresh blood and nutrients. But when we sit for a long time, discs are squashed unevenly. Collagen hardens around supporting tendons and ligaments. So people who sit more are at greater risk of slipped disks or herniated disks.I recommend the Yoga position cat-cow for increasing your spinal flexibility. (Click here for guidelines on how to do cat-cow.)
When you sit for a long time, a muscle called the psoas travels through the abdominal cavity and, when it tightens, pulls the upper lumbar spine forward. Upper-body weight rests entirely on the ischial tuberosity (sitting bones) instead of being distributed along the arch of the spine. A sports massage or a deep tissue massage can release a tight psoas muscle.
Mushy abs
When you stand, move or even sit up straight, abdominal muscles keep you upright. But when you slump in a chair, they go unused. Tight back muscles and wimpy abs form a posture-wrecking alliance that can exaggerate the spine's natural arch, a condition called hyperlordosis, or swayback. So sitting up straight is the first step to good abs!Tight hips
Flexible hips help keep you balanced, but chronic sitters so rarely extend the hip flexor muscles in front that they become short and tight, limiting range of motion and stride length. Studies have found that decreased hip mobility is a main reason elderly people tend to fall. So when you are in the gym remember tohttp://vitalitytherapy.co.uk/wp-admin/post-new.php stretch your hip flexors.Limp glutes
Sitting requires your glutes to do absolutely nothing, and they get used to it. Soft glutes hurt your stability, your ability to push off and your ability to maintain a powerful stride when walking. They can impact your performance when you run, as all powerful glutes are the key to increasing your speed and powering you up hills.Is the way you breathing causing your neck pain? – Part 1
If you have had a treatment with us, we may have talked to you about importance of deep breathing, if you have tension in your neck. Shallow breathing, thoracic breathing, or chest breathing is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using accessory muscles rather than throughout the lungs via the diaphragm. This means that you over use some of the accessory muscles of breathing, including the scalenes and sternocleidomastoid muscles both of which are located in the side of the neck. The scalenes elevate the 1st rib during inspiration and the sternocleidomastoid raises the sternum. Unfortunately, these accessory muscles aren’t built for routine respiration, and they exhaust and eventually injure themselves which may result in pain and/or a reduced range of movement (i.e. inability to turn your head fully from side to side). People shallow breath when they are nervous, stressed, anxious, or when they concentrate. So simply stopping and taking one deep breath after you send each email, can reduce the over use of your scalenes and sternocleidomastoid.
