The trunk is a kinetic link that facilitates the transmission of force and angular moments between the lower and upper extremities, provides proximal stability for distal mobility, and maintains balance by keeping the body weight within the support surface.While trunk muscle strength is important for maintaining daily living activities, trunk muscle endurance plays an important role in preventing injuries by stabilizing the spine during long-term physical activity and sports activities (2).Decreased trunk muscle endurance can result in fatigue and low back pain. Low back pain is a major public health problem worldwide. In modern industrial society, the number of low back pain patients is increasing due to sedentary lifestyles, lack of exercise and working conditions.The lifetime prevalence of low back pain has been reported as 84%.80% of low back pain is nonspecific, that is, muscle weakness and ligament-related reasons for unknown reasons(3,4).Increasing the endurance of the waist muscles with exercise is used in the treatment of low back pain. From this point of view, while planning our study, we wanted to evaluate whether the decrease in trunk muscles is associated with low back pain and fatigue in young adults.
Our research will be carried out in healthy youngs adult volunteers between the ages of 18-24.It is a non-invasive cross-sectional observational study without a control group. No device will be used.The following measurement and evaluation methods will be applied to all individuals who voluntarily agree to participate in the research.First, demographic data will be collected with the Patient Evaluation Form. For trunk endurance measurement, McGill Trunk Muscle Endurance Tests, Modified Biering-Sorensen test and Lateral bridge test will be used.These tests measure muscle strength in seconds with examination as described below and do not require a device.Fatigue severity scale and Roland Morris Disability Form will be filled to evaluate fatigue and lumbar network.Physical Activity level will be measured with the International Physical Activity Scale.

Trunk flexors endurance test: Participants will be positioned with trunk flexed to 60º, knees and hips to 90º flexion. The evaluator fixes the feet on the ground by supporting them from the toes. When the 60º trunk flexion is broken, the test will be terminated and the time it maintains this position will be recorded in seconds. Modified "Biering-Sorensen" test: With this test, the endurance of trunk extensors is evaluated. The subjects are positioned in the prone position with the pelvis, hips and knees on the bed. The subjects are asked to extend their upper body straight forward from the edge of the table and the time they maintain this position will be recorded in seconds. Lateral bridge test: During the test, the subjects were asked to lie on their side, raise their bodies on their forearms and toes and maintain this position, and the time they held the position would be recorded in seconds. The test will be done on both sides.
"Fatigue Severity Scale" was used to evaluate the fatigue level of the participants. This scale consists of a 7-point Likert scale. 1 point means strongly disagree, 7 means strongly agree. High scores are associated with increased fatigue. Evaluates the effects of fatigue on physical function, motivation, family and social life. Turkish validity and reliability was established.
The "Roland Moris Scale" will be used to evaluate the participants for low back pain assessment. The Roland Morris Inquiry Form was designed to evaluate the functional disability of the patient. The total score ranges from 0 (no disability) to 24 (severe disability). The higher the total score, the lower the patient's functionality. It is a questionnaire filled by the patient, which evaluates the functionality of 24 items questioning the patient's mobility, self-care and sleep status. Each item marked as 'Yes' is given 1 point, and answers marked as 'No' are given 0 points. Turkish validity and reliability was established.
The physical activity level of the participants will be measured with the International Physical activity scale: MET values will be calculated according to this scale, which has Turkish validity and reliability.
