Background This study aimed to identify latent moderate-to-vigorous intensity physical activity (MVPA) and sedentary behavior (SB) trajectories in older adults participating in a randomized intervention trial and to explore associations with baseline social-cognitive predictors. Methods Data were assessed at baseline (T0, participants were inactive or had recently become active), after a ten-week physical activity intervention (T1), and a second 24-week intervention phase (T2). Latent class growth analysis was used on accelerometer-assessed weekly MVPA and daily SB, respectively ( n  = 215 eligible participants). Activity changes within trajectory classes and baseline social-cognitive predictor differences between trajectory classes were analyzed. Results A “stable insufficient MVPA” ( n  = 197,  p  for difference in MVPA level at T0 and T2 ( p  T0-T2 ) = .789, effect size (Cohen’s  d ) = .03) and a “stable high MVPA” trajectory ( n  = 18,  p  T0-T2  = .137,  d  = .39), as well as a “slightly decreasing high SB” ( n  = 63,  p  for difference in SB ( p  T0-T2 ) = .022,  d  = .36) and a “slightly increasing moderate SB” trajectory ( n  = 152,  p  T0-T2  = .019,  d  = .27) emerged. Belonging to the “stable high MVPA” trajectory was associated with higher action planning levels compared to the “stable insufficient MVPA” trajectory ( M  = 5.46 versus 4.40,  d  = .50). Belonging to the “decreasing high SB” trajectory was associated with higher action self-efficacy levels compared to the “increasing moderate SB” trajectory ( M  = 5.27 versus 4.72,  d  = .33). Conclusions Change occurred heterogeneously in latent (not directly observed) subgroups, with significant positive trajectories only observed in the highly sedentary.
