To penetrate the thin saw through the wood, the woodcutter continuously moves the saw back and forward to apply the friction and the pressure to run it through the wood and cut it into two. Do adequate warm-up and cool-down maneuvers (crucial to proper tendon and bursae health). For example, its possible for children to slide freely on various slides only because there is the presence of gravity; moreover, while sliding, children also experience low friction; leading to an easy and smooth slide. For example, a pendulum, flapping of bird wings, etc. Repetitive Motion Injury (RMI): Also known as repetitive stress injuries, an RMI is a type of stress injury that results from repetitive motions such as frequent bending or sustained awkward positioning performed over extended periods of time without allowing for sufficient rest. 7 Summing-up. overuse syndrome, cumulative trauma disorder, repetitive stress injury, repetition strain injury, tendonitis/tendinitis, tenosynovitis, bursitis, carpal tunnel syndrome, tennis elbow, gout, rotator cuff, repetitive motion injuries.
