Some athletes who undertake strenuous training programs for a prolonged period of time develop the overtraining syndrome. The pathophysiology of the condition is unknown. Hypothalamic-pituitary function was studied by determining the hormonal responses to insulin-induced hypoglycemia in five asymptomatic male marathon runners during a 4-month period in which they ran 42-, 56-, and 92-km races and in four overtrained male athletes. The response of the asymptomatic runners was not different when…

Impaired pituitary hormonal response to exhaustive exercise in overtrained endurance athletes.

The hypothesis of a hypothalamo-pituitary dysregulation during OT expressed by an impaired response of pituitary hormones to exhaustive short-endurance exercise is confirmed.

Hormonal Responses to Endurance Training and Overtraining in Female Athletes

Hormone responses to exercise load are superior in indicating heavy training-induced stress when compared with resting hormone levels, and individual hormonal profiles are needed to follow up training effects.

Hormonal responses in athletes: the use of a two bout exercise protocol to detect subtle differences in (over)training status

The results of the case presentation of an overtrained athlete provide evidence of an altered and dysfunctional hypothalamic–pituitary axis response to two bouts of maximal exercise that can be used to develop markers for diagnosis of OTS and to address the pathologic mechanism operative in the syndrome.

Hormonal responses to acute exercise, training and overtraining a review with emphasis on the horse

A summary of previous literature examining the response of the hypothalamic‐pituitary‐adrenal (HPA) axis and the growth hormone‐insulin‐like growth factor‐I (GH‐IGF‐I) axis to acute and chronic exercise as well as overtraining in humans and horses is provided.

Exercise and Male Hypogonadism: Testosterone, the Hypothalamic-Pituitary-Testicular Axis, and Exercise Training

Male athletes with chronic training overload may develop the exercise-hypogonadal male condition with a corresponding reduction in resting testosterone levels, possibly due to both central and peripheral regulatory compromises.

Overtraining effects on immunity and performance in athletes

There is evidence that several immune parameters are suppressed during prolonged periods of intense exercise training, and the mechanisms underlying overtraining syndrome have not been clearly identified, but are likely to involve autonomic dysfunction and possibly increased cytokine production resulting from the physical stress of intense daily training with inadequate recovery.

Overtraining in Elite Athletes

Overtraining is an imbalance between training and recovery that can be explained as a stress response and no sensitive and specific tests are available to prevent or diagnose overtraining.

Physiological profiles of overtrained and stale athletes: A review

The intent of this review is to characterize the physiological changes found in athletes exposed to overtraining or exhibiting a state of staleness, and changes and responses in five general physiological systems are discussed.

Blood Hormones as Markers of Training Stress and Overtraining

An intraindividually decreased maximum rise of pituitary hormones (corticotrophin, growth hormone, cortisol and insulin has been found after a standardised exhaustive exercise test performed with an intensity of 10% above the individual anaerobic threshold, suggesting an impaired hypothalamic regulation.

On the physiological and psychological differences between functional overreaching and acute fatigue

The observed changes in hormonal levels may be regarded a normal response to this high demanding cycling event, rather than maladaptation that results in underperformance (FOR).



Menstrual dysfunction in distance runners.

It is concluded that menstrual dysfunction in distance runners is a real phenomenon and presumably this is related to decreased percentage of body fat and/or minimal ovarian function secondary to diminished hypothalamic or pituitary hormone secretion.

Hypothalamic amenorrhea in runners of normal body composition.

Three amenorrheic runners of normal body weight, in whom organic disease had been excluded, were found to exhibit: (1) normal body composition, (2) low baseline concentrations of serum LH and normal

Energy drain may have an important modulatory effect on the hypothalamic pituitary set point at puberty and, in combination with low body weight, may prolong the prepubertal state and induce amenorrhea.

Exercise, Body Weight, and Amenorrhea in Professional Ballet Dancers.

Professional female ballet dancers studied by means of a gynecological questionnaire found that menstrual dysfunction was related to both strenuous physical exercise and diminished body weight, and it was reversible, often disappearing with significant weight gain or intervals of less intense exercise.

Regulation of the adrenocortical response to insulin-induced hypoglycemia.

Although the direct response to hypoglycemia was abolished by pentobarbital, the magnitude of the corticosteroid response to a surgical stimulus was increased in markedly hypoglycemic rats compared to that in euglycemic controls, suggesting that low glucose levels may act at some point in the final common pathway to augment hormonal responses to other stim...

Exercise in Education and Medicine

There seems to be at least one striking exception to the general rule of the easy adaptation of other forms of animal life to the Hawaiian climate, in the case of the eastern oyster, which has repeatedly been introduced, but which has never become acclimatized.
