Are you increasing the distance you are running? How are you knees?

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.

We all know we need to maintain good posture, but what exactly is good standing posture? Good standing posture When standing, keep these tips in mind:

• Keep your shoulders back and relaxed.
• Pull in your abdomen.
• Keep your feet about hip distance apart.
• Balance your weight evenly on both feet.
• Let your hands hang naturally at your sides.

Try not to tilt your head forward, backward or sideways, and make sure your knees are relaxed — not locked.

Take the wall test

To test your standing posture, take the wall test. Stand with your head, shoulder blades and buttocks touching a wall, and have your heels about 2 to 4 inches (about 5 to 10 centimeters) away from the wall. Reach back and slide your hand behind the curve in your lower back, with your palm flat against the wall. Ideally, you'll feel about one hand's thickness of space between your back and the wall. If there's too much space, tighten your abdominal muscles to flatten the curve in your back. If there's too little space, arch your back so that your hand fits comfortably behind you. Walk away from the wall while maintaining this posture. Keep it up throughout your daily activities.

Check out your reflection

To see if you're keeping your shoulders straight, stand in front of a mirror. Aim to keep your shoulders square and relaxed.

It all adds up

Although good posture should be natural, you might feel wooden or stiff at first if you've forgotten the sensation of standing up straight. The key is to practice good posture all the time.  Remember its never to late to start practicing good posture.  

Previously I discussed how dehydration & lack of sodium or potassium may cause muscle cramps.  I now want to explore other nutritional factors. Calcium Calcium plays an essential role in muscle contractions.  Some active people report their problem with cramping disappears when they boost their calcium intake.  This anecdotal evidence is disputed by scientists who state that when dietary deficiencies of of calcium occur, calcium is released from the bones to provide what the body needs for proper muscle contraction.  If you are plagued by muscle cramps, it may be worth trying to increase your intake of dairy or other calcium rich foods to see if it helps. Magnesium Just as muscles need calcium to contract they need magnesium to relax. Roffe et al demonstrated that magnesium helps reduce leg cramps that occur in the middle of the night.
