 The assessment of exercise tolerance is an important part of clinical diagnosis of health status in children and adolescents. It can provide valuable information regarding the cardiovascular, respiratory, and musculoskeletal system functions, as well as the overall physical fitness of the child. Different tests can be used to measure exercise tolerance, such as treadmill tests, cycle or gometer tests, and other forms of exercise testing. These tests allow for continuous monitoring of heart rate, blood pressure, ECG recordings, and blood oxygen saturation levels. Additionally, maximal oxygen consumption, VO2 max, can be measured directly or estimated using indirect methods. The results of these tests can provide valuable insight into the health status of the child and can help guide treatment decisions.
