Levels of PA are based on the EVS total score of minutes per week in moderate to strenuous exercise; Inactive (0 min·wk.⁻¹), Insufficient PA (1–149 min·wk.⁻¹), and Sufficient PA (≥ 150 min·wk.⁻¹)

PTSD symptom severity is based on the HTQ total score and divided into the AIS and ANS subscales

PTSD, post-traumatic stress disorder; PA, physical activity; HTQ, Harvard Trauma Questionnaire; AIS, arousal and intrusion symptom subscale; ANS, avoidance and numbing symptom subscale; EVS, Exersice Vital Sign; n, sample size; M, mean; SD, standard deviation; F, Fishers test; p, probability value
