HFRG Defensive Tactics Exam Study Questions and Answers 2024

Combat anxiety - the anticipation of danger Survival stress - deadly force threat perception that initiates the SNS discharge Combat stress - deals with the post event mental & physiological symptoms that are a result of the SNS activation and the sudden return to the Parasympathetic Nervous System (PNS). This is known as the PNS "blacklash", which may distort the memory. autonomic nervous system (ANS) - the organs of our body, such as the heart, stomach, and intestines, are regulated by the autonomic nervous system (ANS). ANS Two Branches - the parasympathetic nervous system (PNS) and the sympathetic nervous system (SNS). Motor Skill Classifications - there are three basic motor skill classifications; fine, complex, and gross. Fine motor skills - skills that require hand/eye coordination and hand dexterity. When the heart rate reaches 115 BPM, vasoconstriction in the fingers and hands effects the dexterity required to preform the fine motor skills. - Complex motor skills - skills that involve a series of muscle groups in a series of movements requiring hand/eye coordination, precision, tracking and timing. At approximately 145 BPM, complex motor skills begin to deteriorate. - Gross motor skills - skills that involve large muscle or major muscle groups. Examples of a gross motor skill include simple actions such as a straight punch, a forward baton strike, or the isosceles shooting stance. What BPM range is for optimal survival and combat performance? - Between 115 and 145 BPM The Inverted U Law - Performance will gradually deteriorate as stress (arousal) increases. Parasympathetic Nervous System "Backlash" - These are called backlash triggers and include the perception that the threat has diminished or that there has been an injury. Trauma to a vital system or exhaustion of the aerobic and anaerobic systems can also cause this negative backlash. Critical Incident Amnesia - This temporary amnesia will affect both the officer's memory, and the officer's ability to write an incident report. Timetable to memory recovery - The most complete recovery of memory will occur after the second sleep period. Incident Reporting - The first report should be verbal and titled "preliminary" report. A "supplemental" debrief/report should not be prepared until after the first sleep period, and the final report should be prepared until after the second sleep period has occurred. Proteins - a group of amino acids that maintain and build muscle used as an energy source during times of stress and to increase mental performance. ATP/PC System - The ATP system consists of small energy bundles that are stored in the muscles. This system is used during high energy and high strength activities, such as sprinting, lifting heavy weight, or defending against and aggressive assault. When this system is engaged, the officer is able to perform at 100% of his/her maximum output. ATP/PC System (Burnout) - The system burns out after 10-15 seconds, at that time the officer can expect to have a 45% decrease in maximum output. Motor Skill Selection - As stated in Hicks Law study, if a person has more than one option to select from, their reaction time increases. In this study, it was determined that each time a response is added, reaction time will increase 58%. HFRG Components of Acceptability - All HFRG training programs are based upon the three HFRG Components of Acceptability: Tactical Acceptability, Legal Acceptability, and Medical Acceptability, which are all based on documented tactical, legal and medical research. Total Control Theory - associated with a training system centered upon the use of an intermediate weapon (such as a straight baton, side handle baton, chemical agent or electrical control device. One-Plus-One Theory - The most conservative use of force theory, based on the concept of responding to resistance with proportional use of force. Use of Force Justification - -To stop potentially dangerous and unlawful behavior -To protect the officer or another from injury or death -To protect subjects from injuring themselves -And in the process of effecting a lawful arrest when a subject offers resistance Types of Subject Resistance - -Inactive Resistance -Passive Resistance
