Stress

QuestionAnswer
What is it important to diagnose? factors that limit the performance
stress physiological stimuli are called stress (mechanical force)
What does stress try to do? try to alter organisms internal environment
Response or strain Acute, temporary functional changes in the organism in response to stress
Adaptation chronic, long term changes in structural/functional in the organism
Distress the response of organisms to abnormally large stress which results in reduced functional capacity of organisms
Homeostasis State of a normal and constant internal environment regardless of the stress disrupting it
steady state Steady, unchanging internal environment or physical variables (HR, VO2, temp, Blood pH) – does not guarantee normality
Heat stroke proteins/ Stress proteins repair the damaged proteins & cellular structures induced by heat stress – enhance the capacity of the stress – improving functional capacity
Negative FB Mechanism A system in which the final response is opposite to initiating stimulus
components of Negative FB -sensor -integrator/controller -regulate -effector
Positive FB mechanism (vicious cycle) – A system in which the final response is in the same direction as the initiating stimulus
