Mechanical Energy as the Ability to Do Work. An object that possesses mechanical energy is able to do work. In fact, mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy-whether it is in the form of potential energy or kinetic energy-is able to do work.s already mentioned, the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.
A towel stretch is an effective way to stretch your psoas muscle. You can use a regular bath towel or a strap that's roughly the same length. To do the stretch, lie close to the edge of your bed on your stomach. Plant your outside foot on the floor and bend your other leg.
The hypertonicity of the psoas muscle has a tendency to flex the lumbar spine, causing the lumbar spine to diminish in lordosis especially when a weakness of the erector spinae is present. The muscles involved in hip extension and abduction can be divided into two groups, postural and phasic (Table 1).he three muscles are the gluteus maximus(primary mover/agonist), biceps femoris(synergist) and erector spinae(synergist). Any deviation from the specific muscle activation is considered an altered movement pattern. This will cause hip extension dysfunction, muscle imbalance, pain and contribute to changes in posture.
