Abstract: | This 9 month prospective study, conducted at the US Army Sergeants Major Academy (USASGMA), examined the association of selected psychological variables (e.g., measures of tension/anxiety, sleep disturbance, Type A behavior pattern) with injury occurrence and physical performance in 126 soldiers. ANOVA and logistic regression analyses revealed significant relationships between: 1) Traumatic injury occurrence and mean tension/anxiety scores, 2) Mean self-reported sleep disturbance scores and traumatic injury occurrence, 3) The Type A behavior pattern (abbreviated Jenkins Activity Survey) and number of sit-ups repetitions completed in 2 minutes, one component of the Army Physical Fitness Test (APFT), 4) The Type A behavior pattern and total score APFT. No significant associations were found for mean tension/anxiety scores and overuse injuries, or Type A behavior pattern and two mile run time or number of push-up repetitions completed in 2 minutes. These data suggest traumatic injury occurrence is influenced by tension/anxiety and disturbances in sleep habits. Additionally, individuals with higher Jenkins Activity scores (characteristic of the Type A behavior pattern) perform better physically. |
