More factors that contribute to muscle cramps

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.

  • Why does slumping at your desk contribute to lower back pain?

    We all know that we should maintain good posture when sitting rather than slumping (poor posture) to avoid lower back pain, but why? The human spine is an upright bendy column and in someone with good posture it’s an S shape.  With perfect posture a straight line can be drawn through the ear, the tip of the shoulder, the front of the knee joint and the back of the ankle. The spine is made of 24 vertebrae or segments.  If we look at the S shape it consist of the cervical lordosis which is the arch in the neck, this is followed by the thoracic kyphosis which is an arch in the chest in the opposite direction, this is then followed by the lumbar arch or lumbar lordosis which is the hollow in the lower back. Perfect lumbar lordosis (or perfect arch in your lower back) helps

    • Ensure the correct distribution of your body weight
    • Allows your lower back to bow forwards slightly when walking to absorb the impact during walking
    The lumbar lordosis lessens when we are sitting as our pelvises tip backwards on to the sitting bones and increases when we stand.   This explains why some people with lower back pain feel worse when sitting and better when standing.  Furthermore sitting for long periods of time in a slumped “C” shaped posture, changes our weight distribution through our spine, compressing the lumbar vertebra which often leads to lower back pain. So what is good sitting posture? When seated, keep these tips in mind:
    • Choose a chair that allows you to rest both feet flat on the floor while keeping your knees level with your hips. If necessary, prop up your feet with a footstool or other support.
    • Sit back in your chair. If the chair doesn't support your lower back's curve, place a rolled towel or small pillow behind your lower back.
    • Stretch the top of your head toward the ceiling, and tuck your chin in slightly.
    • Keep your upper back and neck comfortably straight.
    • Keep your shoulders relaxed — not elevated, rounded or pulled backward.

    Remember

    Although good posture should be natural, you might feel wooden or stiff at first if you are used to slumping rather than sitting up straight.  The key is to practice good posture all the time, and be extra vigilant when you are really concentrating, getting tired or its late in the day. You can make improvements at any age. Stretching and core strengthening exercises can help, too. And if you have got lower back pain, why not try massage.  

  • Stretches for Head, Neck and Shoulders

    These stretches can either be done as a complete series or individually and most of them can be done at your desk.  Some will ease tension in specific parts of the body whilst others are generally relaxing.  Please remember stretching should always be relaxing and never painful! To get maximum benefit from these stretches you should do them daily and hold each stretch for 15 seconds and repeat twice. Head And Neck

    • Head rotation - keeping your head level, slowly turn from side to side.
    • Slowly drop your head sideways moving your right ear towards your right shoulder and push down with your left shoulder - repeat on other side.
    • Stand with your feet shoulder distance apart; look down towards your right foot (hold for 15 seconds),  dropping left shoulder - repeat the exercise looking towards your left foot.
    • Drop the lower jaw and open the mouth wide.
    Shoulders
    • Shrugging shoulders in a circular movement - forwards and then backwards.
    • Raise your shoulders high and let them drap heavily; whilst letting breathing out.
    • Clasp hands behind your head, with elbows back - push your chin back.  Hold for 15 seconds.  From this position look down and push your elbows together at the front and hold for a further 15 seconds.
    • Clasp you hands and push up towards the ceiling, palms up now look down.
    • Sit upright in a chair with a firm seat.  Raise your arms as high as possible and remaining seated drop forward letting your head and arms hang heavily towards the floor.
       

  • More how to chill out…

    In my previous post I said that the activity you do to chill out doesn't matter it you just need to enjoy it and it absorbs you. So why not consider paying video games, yes video games.  If you ask any gamer, who enjoys playing them and they will tell you it help them relax or de-stress.  I know this may sound unlikey.  However that is scientific research to support the idea that regularly playing video games can help people unwind an dimprove their ability to handle everyday stress. In 2010 Associate Professor Dr. Christopher J. Ferguson of the Texas A&M Public Research Facility demonstrated that both men and women who play violent video games long-term seem to be able to adopt mental skills to handle stress, become less depressed and get less hostile during stressful tasks.  In 2014 reserarchers from University College London  found that people who played video games after work experienced faster recovery from work related stress. While there are a number of video games on the market which are specifically aimed at helping people unwind and manage stress, it seems that almost any form of game playing will do the trick.  Spending half an hour each day on a video console could be be as effective as going to the gym for helping you “chill out” at the end of a busy day.
