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.
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.
