Relationship of Exercise Capacity With Physical Activity Level, Sleep Apnea Risk and Quality of Life in Obese Adults

The incremental shuttle walking test at increasing speed (ISWT) is one of the field tests used to evaluate exercise capacity. It has been shown that ISWT is a valid and reliable assessment tool that can be used to evaluate exercise capacity in obese individuals. This test is an exercise test in which walking between two cones 10 m apart at increasing speed for 12 minutes is counted as one sit-up for each 10-meter walk between the two cones. It is continued until the patient is unable to continue the test due to shortness of breath, the heart rate reaches 85% of the maximum expected heart rate, or completes the 12-minute test. In this test, the primary measure is the distance walked, and the result is calculated based on the number of shuttles completed.
