HFRG Skills AcademyOptimal Heart Beat for performing complex motor skills - correct answer 115-145 BPM What happens during SNS (Sympathetic Nervous System) activation? - correct answer 1. "Fight of Flight" 2. SNS dominates all VOLUNTARY and INVOLUNTARY systems 3. Visual perceptions become dominant 4. Other 4 perceptual senses become diminished Six tactical implications that the SNS has on Vision - correct answer 1. Tunnel Vision 2. Loss of Near Vision (Hard to focus within 4ft. 3. Loss of Ability to focus (Decrease accuracy, Increase reaction time) 4. Loss of monocular Vision (Inhibits accuracy of distance shooting, May enhance close accuracy 5. Loss of Depth Perception- Assailant appears close/farther away. (Shoot down and to dominant side) 6. Loss of Night Vision- Night Vision preceptors located in peripheral field ***Must Scan*** Four Steps in Survival Reaction Time Process - correct answer 1. Perception 2. Analyze and evaluate level of threat or information 3. Formulate a survival response 4. Initiate motor response (execution of each step, reaction time increases as heart rate exceeds 145 BPM, physical performance poor at 175 BPM) How does SNS effect cognitive processing Rx time? - correct answer 1. Survival Rx time increase 4x 2. Disrupted concentration 3. Failure to develop logical survival response 4. Irrational behavior 5. Repetitive actions 6. Freezing in place
