Within law enforcement and military, the apprehension of a suspect is a common but critical physically demanding strength related task. However, a range of apprehension techniques can be used that may significantly modify the physical demands required to detain a suspect and therefore undermine its utility for inclusion as a bona-fide physical employment standard.

PURPOSE: To determine the influence of using apprehension techniques on the force required to successfully detain a suspect.

METHODS: Nine Royal Australian Air Force personnel (8 males, 1 female, age 25.6 ± 6.9 y) performed an arm retraction simulation on a non-compliant suspect (contained on the ground) to enable handcuffing. Four conditions were used; strength (control) and three apprehension technique conditions (striking, two person and pressure point), to assess the force required to retract the arm of the suspect. Peak isometric force (Newtons) required to retract the arm in each of the four conditions was measured using a 3.5 kN load cell attached to a wrist cuff using high-tensile rope. A one-way repeated measures ANOVA was used to assess differences between each condition.

RESULTS: The use of technique to apprehend a suspect significantly reduced the peak isometric force required to retract the arm (Figure 1). However, there was no significant difference between each of the arm retraction techniques.

CONCLUSION: The physical demands of performing an apprehension task were modified significantly with the use of technique. Therefore the inclusion of an apprehension task as a physical standard for employment appears to be problematic.
