Cardiorespiratory fitness (CRF) is the core element of health-related physical evaluation. High pressure and low oxygen in Tibet (over 3,500 m above sea level) may negatively impact residents' CRF. The 20-m shuttle run test (20mSRT) most popular field-based assessment estimate CRF children adolescents worldwide. However, normative data for residing China's plateau region are unavailable, which prevents comparability among those living at high-altitudes around world.To measure Chinese aged 9-18 years altitudes exceeding m, to identify correlations between this metric demographic characteristics (age, sex, ethnicity). These were then compared with generated lowland (Shanghai, China) various global regions.20mSRT performance (number completed laps) predicted peak consumption (VO2peak) used as indicators We measured 1,717 healthy Tibet. from school-age subjects Shanghai (2,437 boys 2,396 girls) worldwide (1,142,026 students 50 countries/regions Africa, Asia, Europe, Latin America, North Oceania) collated published papers.The average participants was 39.8 mL/kg/min. male (n = 876; 41.1 ± 4.42 mL/kg/min) had a higher than their female counterparts 841; 37.8 5.40 mL/kg/min). decreased age both sexes statistical significance (F 1249.9, p trend 0.05). indigenous Tibetans 1289; 40.1 3.71 significant Han descent 394; 38.9 4.70 (p < 0.05).Children 7-18 displayed lower traits plains area other high altitude places. varied according age, ethnic group. Given importance adolescents, effective intervention strategies should be implemented improve on plateau.
