About this trial
This is an interventional basic science trial for Muscle Tightness focused on measuring multifidus, erector spinae, muscle stiffness
Eligibility Criteria
Inclusion Criteria:
- Physically active at least 3 hours a week
Exclusion Criteria:
- Low back pain in the past 6 months
- History of chronic low back pain
- History of spinal or pelvic operation
- Hypermobility, more than 4 points on Beighton scale
- Cardiovascular or systemic diseases
- Pregnancy
Sites / Locations
- University of Primorska, Faculty of Health Sciences
Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Isometric fatigue
Arm Description
Fatiguing intermittent isometric exertions of trunk extensor muscles will be performed.
Outcomes
Primary Outcome Measures
Change of trunk extensors muscle stiffness
Muscle stiffness will be measured at rest and during standardised sub-maximal exertions in prone lying position. Muscle stiffness will be expressed as the shear modulus value in kilopascals.
Secondary Outcome Measures
Change of muscle electromyography mean amplitude
Muscle activation of trunk extensors will be measured using superficial electromyography at rest and during two standardised sub-maximal exertions in prone lying position (single arm raise and upper body raise). Mean amplitude in six to eight second time frames will be calculated.

Intervention Type
Other
Intervention Name(s)
isometric trunk extensor muscles fatigue
Intervention Description
Participants will perform three sets of intermittent isometric efforts between 50 and 60 percents of their maximal isometric strength. A padded force sensor will be placed approximately at the level of the 7th thoracic vertebrae. The first two sets will last six minutes each, while the third set will last three minutes. Between each set participants will rest for two minutes.
