Technology is evolving before our eyes! Just a moment ago the flip and slider mobile phones were all the hype. It was considered, smaller the device the more advanced the technology. However, mobiles are getting larger! Technologies like mobile, computer, laptop and/or tablets are now a staple accessory (or in some cases an additional arm) for students, workers, or anyone.
Subsequently, with the development of hi-tech devices, there is an increase of people being sedentary.
Sitting is just about in most things we do in our lives, in particular at school and work. Back and neck pain/discomfort are becoming a common occurrence. Discomfort and pain result from ‘constrained’ postures. The main sitting constraints include forward head carriage, hiking or rolling forward of your shoulders, and slumping of your back.
Prolonged static loading on the muscles leads to early muscular fatigue.1
Muscular fatigue is defined by a decline in muscular performance. Muscles have an inability to maintain the required or expected force or power output in everyday activities. This deconditioning is a result of restricted physical activity that results in a significant decrease of muscles mass and consequentially strength.2
Sitting for ‘long periods’ of time places additional stress on your back. Postural awareness is decreased and muscular fatigue sets in. Not to mention the effects on the cardiovascular system. Minimising these prolonged sitting positions can be simple as varying the tasks throughout the day. Such strategies include taking breaks every 30 minutes, posture training and improving ergonomic work conditions.
