This investigation determined the influence of technique and experience on arm retraction force required to apprehend a non-compliant suspect. Phase-One: Nine experienced RAAF military-police completed four apprehension simulations, peak arm retraction force was measured; i) Control( CON ), ii) Pressure-Point( PP ), iii) Targeted-Striking( TS ) and iv) 2-Person( 2Per ) techniques. Phase-Two: Experienced ( EXP , n = 8 ) or Inexperienced ( INEXP , n = 22) military-police completed CON , PP and Pressure-Point + Coaching( PP + C ). Strength was assessed in INEXP . EXP produced more force (178.7 N ± 25.9) than INEXP during CON , but no participant successfully apprehended the suspect. All EXP were successful with PP , arm retraction force 357 N (CI: 233.7,480.2) was lower compared to CON, but no difference was observed between PP and CON for INEXP . PP + C , 82% of INEXP were successful, force declined 138.2 N (CI: 67.8,208.5) compared to CON . All EXP required PP for successful apprehension. INEXP required PP + C for apprehension success. Muscular strength had a limited relationship with arm retraction force. Practitioner summary: For law enforcement personnel, apprehension of a suspect is a critical and physically demanding task, where success is associated with muscular strength and technique. We observed success in the apprehension of a simulated suspect by military law enforcement personnel was primarily determined by participant skill and experience and not muscular strength. |
