Stress
| Question | Answer |
|---|---|
| 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 |
