Final answer:
Decreased body temperature would not be considered part of the sympathetic fight-or-flight response; it is actually more likely to increase during such a response. The symptoms experienced by the individual in the case study suggest overtraining, which has different symptoms from those of the acute stress response.
Step-by-step explanation:
When discussing the physiological changes that occur as a part of the sympathetic fight-or-flight response, we're looking at how the body reacts to stress or perceived dangers. Among the options provided, decreased body temperature is the one that would not be considered part of this response. During the fight-or-flight response, the body's temperature can actually increase due to heightened metabolism and increased blood flow to muscles. In contrast, decreased pH of the blood, increased carbon dioxide, and increased exercise are all changes that can be associated with this stress response. The symptoms experienced by Jasmin, as mentioned in the case study, also suggest the possibility of overtraining, which includes not only fatigue and muscle cramps but also issues like blurry vision and vomiting, indicative of the body's need for rest and recovery.
