PURPOSE: To validate the International Physical Activity Questionnaire-Short Form (IPAQ-SF)the Chinese college students using health-related fitness tests. METHODS: 2513 (1698 males & 815 females; Aged 18.8 ± 0.8 yr.; Height = 170.1 ± 7.8 cm; Weight = 63.1±11.3 kg; BMI = 21.6±2.7) colleges students from a Chinese university were assessed using both IPAQ-SF and a set of physical fitness tests, including vital capacity (VC), step test, standing long jump (SLJ), and 50-M dash for everyone, sit-ups and 800-M run/walk for female students, push-ups and 1000-M for male students. Total, vigorous, moderate and walking MET-hours per week were derived from IPAQ-SF first and then correlated with physical fitness test scores. RESULTS: Descriptive statistics of IPAQ-SF and fitness tests were summarized as below:Table: No title available.The correlations between the IPAQ-SF the fitness tests were summarized as below:Table: No title available.CONCLUSION: Consist with the findings of other validation studies, only low correlations between physical activity time measured by IPAQ-SF and physical fitness were found, which provide some validity evidences to support the Chinese version of IPAQ-SF.
