Brief Summary:
In this study, our primary aim is to investigate the effects of structured core stabilization exercise program on functional capacity, body composition, muscle strength, endurance, balance, quality of life in adult obese individuals expecting bariatric surgery. Our secondary aim is to provide the individual with exercise habits and increase the level of physical activity in daily life with the exercise program planned according to the needs of the individual.

Arm Intervention/treatment
Experimental: Core-Stabilization Exercise Other: Core-Stabilization Exercise
A program consisting of core stabilization exercises and physical activity counseling accompanied by physiotherapists will be applied to the study group.

Experimental: Counseling of physical activity Other: Counseling of physical activity
Only physical activity counseling will be given to the subjects in this group.

Primary Outcome Measures :
  1. Six Minute Walk Test [ Time Frame: Change from baseline to 8 weeks, follow up at two months ]
    The Six Minute Walk Test was conducted according to a standardized protocol, using an internal hallway with the 30-meter distance marked by colored tape on the floor. Participants will be told that "the purpose of this test is to see how far you can walk in six minutes." Then, they will be instructed to "walk from end to end of the hallway at your own pace, in order to cover as much ground as possible." Participants will be allowed to stop and rest during the test, but will be instructed to resume walking as soon as they were able to do so. Before the walk started and at the end of the 6-min walk, participants will be shown a modified Borg dyspnea scale printed on a card and asked to "indicate your current degree of shortness of breath" on a scale of "0 = nothing at all" to "10 = very, very severe." At the end of the walk, they will be asked if they had experienced any of the following specific symptoms: dyspnea, chest pain, light-headedness, or leg pain, or any other symptoms.

  2. Assessment of Core Stabilization [ Time Frame: Change from baseline to 8 weeks, follow up at two months ]
    Core stabilization evaluation will be done with Anterior and Side Abdominal Strength Tests, Trunk Flexor Test and Modified Push Up Test. These tests will be performed using a 2 kilogram medicine ball. Test positions are supine and sitting position.

Secondary Outcome Measures :
  1. Bioelectrical Impedance Analysis-obesity score [ Time Frame: Change from baseline to 8 weeks, follow up at two months ]
    Body components such as body fat percentage, body fat amount, lean body percentage, lean body mass, body water percentage, body water quantity, body mass index are calculated with bioelectrical impedance analysis. The muscle, fat and water ratio of the cases will be evaluated with Tanita Bioelectric Impedance Device. When the device assess the body fat percentage, body fat amount, lean body percentage, lean body mass, body water percentage, body water quantity and body mass index, it offers to us a score as called obesity score.

  2. Biodex Balance System-Fall Risk Test [ Time Frame: Change from baseline to 8 weeks, follow up at two months ]
    Biodex Balance System is a system that offers the possibility of evaluating the balance statically and dynamically. It is a system that measures the displacements in the center of gravity of a patient standing on an outpatient balance platform and the reactions of the support surface when the surface changes. For the static balance will be assessed with "Fall Risk Test " by using Biodex Balance system. Fall risk test offers to us a total score.

  3. Obesity Specific Quality of Life Scale [ Time Frame: Change from baseline to 8 weeks, follow up at two months ]
    Quality of life (QoL) will be measured using the Obesity Specific Quality Of Life (OSQOL) questionnaire. This disease-specific questionnaire includes 11 questions grouped into four dimensions: 1- "Physical state" (7 questions), 2- "Vitality, desire to do things" (2 questions), 3- "Relations with other people" (1 question), 4- "Psychological state" (1 question). Each question offered five possible answers ('absolutely false', 'fairly false', 'neither true nor false', 'fairly true' and 'absolutely true'), classified according to reduced QoL. For dimensions 1 and 2, a quantitative score is calculated (0% minimal QoL, 100% maximal QoL).
