Similarities and differences regarding acute anorexia nervosa and semi-starvation: does behavioral thermoregulation play a central role?

Objective: To clarify the association between acute anorexia nervosa (AN) and semi-starvation (SS) by focusing on similarities and differences in physiology, mood, and behavior.

Method: A comparison of published literature between these two groups.

Results: Both groups show similar hormonal and metabolic changes in response to caloric restriction and extreme weight loss (~25%).

The Central Role of Hypothermia and Hyperactivity in Anorexia Nervosa: A Hypothesis.

Typically, the development of anorexia nervosa (AN) is attributed to psycho-social causes. Several researchers have recently challenged this view and suggested that (HyAc) are central to AN. The following hypothesis will attempt to clarify their role in AN.

Differing cytokine responses by ethnic groups to a bout of exercise-induced muscle damage: a preliminary report.

Background: Strenuous exercise has been shown to alter immune and inflammatory responses potentially predisposing athletes to infection and injury. Ethnic disparities have been demonstrated in athletic performance and in the way individuals respond to exercise as well as in the predisposition towards certain diseases however, the information relating to immune and inflammatory responses to exercise between ethnic groups is still limited. The aim of this study was to investigate whether serum cytokine levels respond differently to eccentrically-biased exercise in African and Caucasian males.

Changes in serum cytokines after repeated bouts of downhill running.

The purpose of this study was to examine changes in serum cytokines after repeated bouts of aerobically biased eccentric exercise. Six untrained males ran down a -13.5% treadmill grade for 60 min on two occasions (RUN1 and RUN2) at a speed equal to 75% of their VO2 peak on a level grade; runs were spaced 14 d apart.

Tissue trauma: the underlying cause of overtraining syndrome?

An athlete who trains intensely, yet consistently underperforms, is considered to be suffering from overtraining syndrome (OTS). OTS is a complex state that involves a large variety of signs and symptoms. Symptoms include changes in mood or behaviour, decreases or increases in concentration of different blood molecules, and alterations in immune function.
