Reference values and secular trends for cardiorespiratory fitness in children and adolescents with obesity

Aim To present specific reference values for cardiorespiratory fitness (CRF) in children with obesity and to analyse secular trends of CRF in the studied population. Methods Cardiorespiratory fitness, the maximal oxygen uptake (VO 2 max), was estimated with the Åstrand‐Rhyming submaximal bicycle test, in 705 Swedish children (356 girls, 8‐20 years) with obesity according to the International Obesity Task Force (IOTF).
