Use the following to answer questions
Scenario I
Ever since Walter Cannon's original research on the flight-or-fight response,researchers have investigated the brain and bodily processes,constituting what is termed the HPA axis,involved in this response to a variety of threatening stimuli.In his seminal research on general adaptation syndrome (GAS),Hans Selye described how these physiological responses change with prolonged exposure to stress and thereby affect overall health.GAS consists of three phases.The alarm phase begins with exposure to an intense stressor and itself consists of two brief subphases: the shock phase in which the body momentarily cannot respond to the stressor and the antishock phase in which the body rapidly mobilizes resources to overcome it.If the stressor persists,the second phase of GAS termed the resistance phase begins.Here,the body adapts to heightened arousal levels and attempts to deal with the stressor by allocating increased energy to it at the expense of other physiological processes not pertinent to survival.The results of these physiological processes can lead to one of two end stages: Either the stressor is eliminated and the body recovers (the recovery stage)or the body's resistance collapses (the exhaustion phase).
-(Scenario I)When training for ultralong distances,a marathon runner's menstrual cycle stops,illustrating which stage of GAS?
A)resistance
B)shock
C)antishock
D)exhaustion

Quizplus · Accepted Answer

The cessation of the menstrual cycle in a marathon runner due to prolonged stress is an example of the resistance phase, where the body reallocates energy to cope with stress, affecting other physiological processes like reproduction.
