. Previous work suggests that both can be effective but may have different playing execution outcomes. 7 Finally, no interaction effect for sal-T was observed, whereas sal-C was typically greater in week 2 versus week 1. Assuming a sustained increase in cortisol is a marker for negative stress response, 1

characteristics are not fixed, the internal load experienced by a specific athlete for a given external load may also change when these factors are modified (ie, changes in their training status, health, etc). In addition, the stress response (ie, internal load) can be influenced by other stressors (eg

Cortisol has primarily been recognized as a neuroendocrinological stress response associated with distress. Although exercise has

Sport Biofeedback provides feedback on physiological responses related to the sympathetic nervous system’s stress response. Essentially, when the sympathetic nervous system is activated, the body responds physiologically by (a) increasing respiration rate, heart rate, electrodermal activity, and muscle

Regarding periodization, the general adaptation syndrome purports a universal physiological stress response, based on experiments demonstrating that common outcomes (adrenal enlargement, atrophy of the thymus, gastrointestinal ulceration) occur in rodents after a wide array of

Can Lifetime Stress Exposure Impact Acute Stress Responses? Studies have shown strong associations between cumulative stress exposure, which includes all the stressors that a person has experienced throughout his or her life span, and physical and mental health. The biological mechanisms
