Polycystic Ovary Syndrome (PCOS) is associated with hyperandrogenism, hyperinsulinemia and insulin resistance starting in the perimenarchal period. Insulin resistance also increases the risk of developing glucose intolerance, type 2 diabetes, hypertension, dyslipidemia and cardiovascular disorders. Studies on adult women with PCOS show that their aerobic capacity is affected. Therefore, in this study; it was aimed to compare the physical and cardiovascular fitness levels of adolescent PCOS patients with healthy adolescents.

Studies on adult women with PCOS show that their aerobic capacity is affected. Therefore, in this study; it was aimed to compare the physical and cardiovascular fitness levels of adolescent PCOS patients with healthy adolescents.Total fat and muscle ratios will be measured with the bioelectrical impedance test (BIA) instrument for body composition evaluation of individuals in both groups. Body mass index (BMI), waist/hip and waist/height ratios will be recorded. The level of cardiovascular fitness will be evaluated with the PACER test, which is among the Fitness Gram Test Protocol. For physical fitness level, muscular strength parameter will be evaluated with hand dynamometer and knee extensor muscle strength, and muscular endurance parameter will be evaluated with sit-up and push-up tests. Participants' physical activities will be evaluated with the Adolescent Physical Activity Questionnaire (PAQ-A).The quality of life of individuals with PCOS will be evaluated with the Polycystic Ovary Syndrome Quality of Life-50 Scale.
