HFRG threat pattern recognition exam guide 2024

parameters in which the officer operates - on cal application cal environment cal requirements common types of resistance hfrg design methodology - 27 years ago a design methodology of tactical, legal and, medical research was introduced. legal research - the true effectiveness of any system is the defensibility of the system/technique in a court of law. reasonable force was based on: 1. was there a need for the application of force 2. was the relationship between the resistance and the level of force proportional (one plus one theory) 3. was the extent of the subject's injury proportional to the subject's level of resistance or threat to the officer or another 4. was the force applied on a good faith, based upon the perceptions of a reasonably trained officer and the objectively reasonable facts the officer had at the time of incident medical research - the most unique aspect of HFRG training is the extensive medical research supporting its techniques mental states in combat - combat anxiety- the anticipation of danger survival stress- deadly force threat perception that initiates the SNS discharge (sympathetic nervous system) combat stress- deals with the post event mental & physiological symptoms that are a result of the SNS activation and the sudden return to the PNS (parasympathetic nervous system) known as the PNS backlash, may distort memory autonomic nervous system - the organs of our body, such as the heart, stomach, and intestines are regulated by. Part of the peripheral nervous system, and controls many organs and muscles in the body involuntarily. divided into PNS and SNS Inverted U law - relationship between stress and performance associated with activation of SNS balance between fight or flight/ rest and digest is called homeostasis SNS triggers - objective threat perceptions- fact that the threat is within close proximity, minimal time to control threat, person not confident with abilities, or new experience objective fear perceptions- having fear of death, injury, killing, incorrect decision making, failure, or fear itself physical exhaustion- caused by depletion of ATP fuel system or inadequate nutrition, can activate SNS force can escalate due to exhaustion startle response- anthropologists believe early man was a scavenger and not a predator, early man would have been hunted physiological changes caused by SNS activation - adrenal activity- adrenal glands are two small structures situated on top of the kidneys. Both in anatomy and function they consist of two distinct regions. adrenal cortex (outer layer). adrenal medulla (seperate endocrine gland). adrenal cortex has 3 zones (produce own hormones) but nerves are connected to SNS and are involved with the fight or flight response. hormones produced are epinephrine and nor-epinephrine vascular activity- a second set of changes occurs in the blood vessels, particularly vasoconstriction. perceptual narrowing- each of the perceptual senses (sight, hearing, smell, taste, touch as well as "sixth sense") provides info to brain. brain will tune in to sense with the most relevant information. all others are tuned out as they lack immediate significance. once exposed to survival stress, humans become binocular (use of both eyes to process information). This occurs as a survival requirement to receive more light and information. vision- when peripheral narrowing occurs, 70% of vision is lost (spotlight or tunnel vision) sight alignment- the role of the visual system on accuracy has generated considerable debate. The weaver camp places considerable emphasis on using the front sights and targeting with the dominant eye. motor skill classicfications - there are 3 basic motor skill classifications 1. fine 2. complex
