Proposed mechanisms by which obesity increases injury risk

Predominant injuryProposed mechanism
Dental injuryPoorly adapted to “trauma-predisposing behaviour” due to low physical activity level14
Acute TraumaticImpaired postural control; moods disorders15
Overuse InjuriesHigher relative musculoskeletal strain during weight bearing activities for subjects with higher BMI20
Overuse and acute injuriesPoor physical fitness and low prior physical activity level21
Ankle sprainsInability to control momentum during changes in direction5
Ankle sprainsImpaired balance ability17
