Psychologists have conceptualized stress in 3 ways:
Stress can be regarded as a stimulus when the person perceives events or circumstances as threatening or harmful (stressors).
Stress is a response to environmental challenges, if the person examines the real and mental stress that stressors produce.
Stress is really a procedure that involves continuous interactions and adjustments between your person and also the environment.
On the basis of these concepts, stress can be defined as the condition that result when person-environment transactions lead to a perceived discrepancy between the demands from the situation and also the resources from the person’s biologic, psychological, and social system.
This definition may suggest that stress in sports and exercise ought to be understood like a condition that’s challenging, threatening, or even bad for the body. With perfect body condition, finishing a marathon is rewarding. With tight hamstring muscles, the same marathon is stressful. The tight muscles could be the consequence of excessive repetitive use, or overtraining, and now additionally they become stressors. If an athlete with tight hamstring muscles believes that the coming marathon will be a tough challenge, she or he may be comparing it with a previous easily accomplished marathon, understanding that his or her current training was handicapped or not completed because of tight hamstring muscles. If the athlete continues to feel the tight muscles, his or her thinking may evolve into anxiety and fear, which result in psychological stress, which can cause homeostatic imbalance from the musculoskeletal, cardiovascular, respiratory, and digestive systems.
Together, these imbalances manifest as pre-competition anxiety. The physical demands on the working muscles send signals towards the brain, a bottom-up pattern of stress activation. The athlete’s thinking, which includes the memory of past experience, creates tension in the body, a top-down pattern of stress activation. They are examples of interaction between psychological and physical stresses.
Physical training involves repeating a set of exercises with increasing intensity over a long period. Selye2 noticed that exposure to a particular stressor can boost the body’s capability to deal with that stressor in the future through a procedure for physiologic adaptation. The increase in ability and gratifaction with training shows how the body adapts towards the required effort. Selye also recognized that severe and extended exposure to any stressor could ultimately exceed the ability of the machine to cope. Runners who habitually train more than 45 miles a week at moderate to high intensity are known to have chronically elevated cortisol levels and negative mood states.3 Full recovery from overtraining stress may take months of abstinence in the particular exercise.
