Key result
Peak cardiorespiratory fitness below ~40 mL/kg/min indicates elevated cardiometabolic risk in youth.
Why the study?
The study aimed to select the best-performing cardiorespiratory fitness peak estimation equation and synthesize and validate diagnostic thresholds for identifying elevated cardiometabolic risk in youth.

What are the diagnostic thresholds of cardiorespiratory fitness for identifying elevated cardiometabolic risk in youth?
Specific cardiorespiratory fitness peak thresholds can identify elevated cardiometabolic risk in youth with moderate-to-strong diagnostic performance.
These CRF thresholds identify elevated cardiometabolic risk in youth; extends diagnostic evidence for fitness screening in pediatrics.
BACKGROUND AND AIM: peak estimation equations (Barnett, Léger, Matsuzaka) to select the best-performing index, and (ii) performing a systematic review and meta-analysis to synthesize and validate findings. METHODS AND RESULTS: peak thresholds for identifying elevated CMR were 43.2 mL/kg/min for boys and 41.9 mL/kg/min for girls aged <13 years, and 40.0 mL/kg/min for boys and 38.5 mL/kg/min for girls aged ≥13. These thresholds demonstrated moderate-to-strong diagnostic performance, and corresponded to the 20th-40th percentiles of international normative data. CONCLUSION: peak thresholds for elevated CMR in youth, with good diagnostic performance, to aid early identification and prevention.

García‐Hermoso et al. (2025) conducted a meta-analysis in Elevated cardiometabolic risk. Cardiorespiratory fitness peak thresholds was evaluated on Diagnostic thresholds for elevated CMR. Peak cardiorespiratory fitness thresholds for identifying elevated cardiometabolic risk in youth were 43.2 and 41.9 mL/kg/min for boys and girls <13 years, and 40.0 and 38.5 mL/kg/min for those ≥13.
