Figure 2From: Could martial arts fall training be safe for persons with osteoporosis?: a feasibility studyMaximal hip impact forces for sideways and forward MA fall exercises. The maximal hip impact force among all participants (highest Fmax) was corrected either for soft tissue padding (ST, 10% reduction) and wearing hip protectors (HP) that could attenuate the maximum hip impact force by at least 65% (safety criterion 1) or soft tissue padding only (10% reduction) (safety criterion 2). The corrected highest Fmax values were compared with thresholds of safety criterion 1 (700 N: average femoral fracture load for elderly minus two standard deviations) and safety criterion 2 (1900 N: average femoral fracture load for elderly minus one standard deviation), respectively. Asterisks (*) indicate fall conditions that met both safety criteria.Back to article page
