abstract：PURPOSE:This study aimed to examine the longitudinal associations of person-related factors with physical activity (PA) behavior in young adults. METHODS:We analyzed longitudinal self-reported time spent in moderate-intensity PA (MPA; 4-7 METs) and vigorous-intensity PA (VPA; >7 METs) from 499 young adults (49% male) ...
