NATHAN DICKS, MA, CSCS AGILITY TRAINING FOR LAW ENFORCEMENT OFFICERS The ability to react and initiate movement is vital to the safety of law enforcement officers (LEO) in many ways. Oftentimes, LEOs may be attacked by either an armed or an unarmed suspect within a short reactionary gap, or may need to escape the path of an oncoming vehicle for example. Additionally, LEOs are likely to experience quick foot pursuits of suspects, lasting 70 s or less (3). These types of actions require the need for agility, power, and speed. Unfortunately, these needs may be compromised by inactivity and increasing loads of equipment carried. LEOs have been observed to carry between 17 – 25 lb in body armor and duty belts, which are on average 8 – 12% of their bodyweight (1,4). With the increases in load, research has suggested that LEO performances in movement have decreased significantly (1). A more recent study suggests the heavier loads carried may have a direct, negative effect on sprinting ability (5). Including weighing the importance of agility, power, and speed, most departments have a wide variety of resistance training statuses and anthropometric variables that need to be considered before implementation of a program. Tactical facilitators need to consider rate of force development as a priority while training LEOs. Increasing the rate of activation of motor units will positively affect force development, allowing the LEO to accelerate to a higher speed more quickly. Baseline measures and training in the fundamentals of agility and resistance exercise should be emphasized to LEOs early in training but only if the officers are trained enough to warrant these protocols. Over time, and if progressed properly, strength exercises and performing explosive movements (such as heavy squatting and Olympic-style lifts) with officers may help to improve their rate of force development, or acceleration, and absolute speed (7). This article will explain some training techniques to assist officers in improving these necessary components to combat the additional weight of their duty gear. AGILITY TRAINING
