Neuroendocrine responses to running in women after zinc and vitamin E supplementation

Article Abstract:

Short-term supplements may not have any effect on the metabolism and and endocrine responses of women runners. Researchers measured the endocrine responses in ten women who had taken zinc and vitamin E supplements prior to running. Exercise-induced changes were transient and included increased levels of plasma lactate, ACTH, prolactin, and catecholamine. IL-6 and cortisol elevations returned to normal within 24 hours.

Heart rate variability as a predictor of negative mood symptoms induced by exercise withdrawal

Article Abstract:

The effects of the autonomic nervous system (ANS) on the development of a negative mood after a controlled withdrawal of exercise are examined. The study proves that the exercise withdrawal usually leads to significantly higher negative mood scores, though it is not found to have any major effect on the heart rate variability (HRV) of the person.

Expression of lymphocyte subsets after exercise and dexamethasone in high and low stress responders

Article Abstract:

Research indicates that low stress responders (LR) and high stress responders (HR) have different patterns of plasma interleukin 6. Results are based on a study of 18 men and 4 women; topics include hypothalamic-pituitary-adrenal axis and high-intensity exercise.
