Preschoolers' (n = 31) physical activity (PA) levels during indoor and outdoor childcare hours were explored using accelerometers. Participants engaged in 0.54 min/h (SD = 0.59) of moderate-to-vigorous PA (MVPA) and 14.42 min/h (SD = 6.78) of total PA (TPA) indoors compared with 5.03 min/h (SD = 4.92) of MVPA and 31.68 min/h (SD = 0.83) of TPA outdoors. Boys and girls engaged in significantly more TPA outdoors; however, only boys demonstrated a significant increase in MVPA outdoors.
