How Our Body Works –Our Muscle

Did You Know?

  • A muscle tenses (contracts) to hold the joint in position.
  • This is called “static loading”.
  • Static muscles fatigue faster and can cause discomfort and pain if held in place for long periods.

Can you think of any static postures or when our muscles are tense?

  • Sitting is a static posture.
  • Arms stretching forward to type.
  • Slumped over desk when working.
How we sit at computer workstations.

There is growing evidence that there needs to be flexibility in the way we sit at computer workstations, especially for those who work at home.

While there is not one correct way to sit at a workstation, seating should support postures that can be changed frequently within a comfortable range throughout the day.

It should accommodate the:

  • work being done
  • visual demands
  • Workers’ individual

Did you know that sitting at your desk for prolonged periods is a static posture that has the potential to result in musculo skeletal disorders?


These postural defects in turn can cause:

  • Headaches
  • excessive muscle tension in your neck, chest, shoulders, arms and forearms, back, abdomen, hips, and thighs and legs
  • strains and trigger points to muscles
  • joint dysfunction and sprains in your neck, back, and ribs
  • increased loading on the intervertebral discs of your spine
  • impaired function of your breathing muscle (your diaphragm), causing the muscles lifting your upper ribs and shoulders to become overactive and subject to problems

A few good work practices can significantly reduce these risks:    

  • It will reduce fatigue and strain on the neck, shoulders, back and legs.
  • Please remember that the smallest changes can make the world of difference!
  • Setting up your workstation properly may be the single easiest way to prevent injuries.
  • These are guidelines provide you with a simple workstation self-assessment.

Follow through the checklist to set up your workstation correctly.
