The human body has hundreds of muscles that must work together for movement. However, there are some major muscles that are primarily responsible for certain movements of the body. These major muscles are called prime mover muscles. Prime movers are muscle groups that initiate movement and provide the dominant force for a joint movement. For some joints, there is only one prime mover muscle group but others can have multiple muscle groups that are a prime mover for different motions. There are also supporting muscles that assist the prime mover muscles, antagonistic muscles that oppose the movement and fixator muscles that help to slow down the movements and keep them in check.
Several studies have shown that powered bed Muscle Movers LLC Las Vegas reduce the physical efforts required by health care workers, leading to a lower risk of occupation related injuries. These power bed movers are becoming increasingly common in hospital settings. However, little research has been conducted to determine how these battery operated machines impact levels of physiological strain and muscle activation. A recent study compared muscular demands of moving a weighted hospital bed using the powered StaminaLift Bed Mover, the powered Gzunda Bed Mover and manual pushing on six male subjects. Fourteen muscles were assessed to measure the intensity of the effort required. Trunk inclination and upper spine acceleration were also measured for each movement.
To perform the test, each subject moved a loaded hospital bed along a standardized route within a hospital setting. The results showed that both the PBM1 and the PBM2 powered bed movers reduced the levels of physical exertion in the majority of muscle groups tested. This included the back extensors, hip flexors and knee extensors. The results also showed that there was a greater variation in trunk inclination when manually pushing the beds as compared to the powered bed movers.
As well as reducing the intensity of movement, using power bed movers can have other significant benefits. Those who use them regularly can develop pre-existing tension in the agonist muscles of the back, shoulders, arms and core that will allow them to lift heavy loads with less exertion than if they were unloaded onto the movers at the start of the movement. This is because the agonist muscles will be working with a pre-existing level of tension and are therefore able to contract more quickly.
In order to maintain a healthy and functional life, you need strong mover muscles. This is why it is important to exercise and challenge these muscles regularly. This helps to prevent them from getting weak and inefficient over time. Exercises such as walking on a treadmill, lifting weights and swimming can all be used to strengthen mover muscles. In addition, a balanced diet can also aid in the development of these muscles. By consuming adequate amounts of protein, fibre and good fats you can ensure that the movesr muscles are well fed to do their job.
