Brief Summary

The rectus abdominis, which enables the trunk to flex with its activation, and the erector spinae muscles, which provide trunk extension with its activation, are among the structures located in the core region and involved in the stabilization of the spine. While the muscles in the core area actively provide the stabilization of the medulla spinalis, this stabilization is also supported by passive subsystems. Passive subsystem fascia etc. creates structures. Thoracolumbar fascia is one of the important fascias due to its connections with the muscles in the core area. Fatigue etc. of the structures in the core area. As a result of physiological processes, their functionality may decrease, which may affect the stabilization of the core area. Fatigue occurs as a result of lactic acid accumulation in the structures in the body and this process is called the recovery period. The types of exercises performed also affect the recovery period. For this reason, different exercise types such as dynamic and static can be used when creating exercise programs. Due to the functions of the rectus abdominis and erector spinae muscles and thoracolumbar fascia in the body, their effects on the spine and their connections with each other; It is aimed to examine the effect of muscle fatigue in these muscles on the viscoelastic properties of the thoracolumbar fascia and their recovery rates.

Outcome Measures

Primary Outcomes (1)

• Thoracolumbal Fascia Viscoelastic Properties

  Viscoelastic properties of the thoracolumbal fascia (TFL) was performed with the MyotonPRO™ (Myoton AS, Estonia) device. Before and after imeddiately after application of the fatigue protocol. The measurement point determined for TFL of individuals rest were marked with a medical marker pen. During the measurement, the probe of the device was adjusted to pulse once into the skin with a force of 0.4 N and for 15 ms. During the test, the tip of the MyotonPro™ device was placed perpendicular to the marked area and gently pressed against the skin at a depth of 3 mm until the green light came on.

  2 weeks
