I have been thinking recently since I wrote the blog on “Honey, computers are killing our students”, we as PDHPE teachers are in best position to prevent possibles injuries sustained from sitting in front of computers for long periods of time. These problems associated with Neck, Shoulder, Upper Back, Elbow, Lower Back, Fingers and Wrists can all be prevented through frequent breaks during work, the continual change of tasks performed, work satisfaction and physio-therapeutic measures (Klussmann, Gebhardt, Liebers, Rieger, 2008). As PDHPE teachers we can have huge impact on the physio-therapeutic measures described. These measures include frequent stretching and flexibility as well as physical exercises.
If schools were to set a side 5 mins extra after any computer lesson, exam or activity were students are seated for a long period of time, this could have a huge benefits to students physiological and psychological well-being. If we as a PDHPE teacher could find a place for 2 weeks of stretching and physical exercise rather than playing Touch football, Netball or any other sport, this may teach student long term health promotion and injury prevention techniques. These techniques could include Yoga, Pilate’s, ballistic stretches, static stretch, small office games etc.
The role of flexibility is to increase range of motion around a joint, as a body stays sedentary or stressed muscles will constantly contract and shorten. With this continuous strain on those muscles, any slight tear or strain in a muscle fiber will be exacerbated. Physical exercise again will indirectly increase flexibility by an increase in blood flow to the muscles, further from this it may cause the participant to relax through the release of endorphins as well as preventing blood pooling (often experienced on planes).
Therefor as suggested, these exercises could really influence students for the rest of there lives and i beleive with our ever increasing use of technology e.g computers, cars, mobile phones, TV, computer games etc, this is very very necessary.
