Correlations between serum hormones, strength and endurance in healthy elderly South-American men.

Aim: Declines in muscular strength resulting from reduced serum anabolic hormones and neural activity may influence the reduction in aerobic capacity in older men. However, there has been little investigation into the relationship between steroid hormones and muscular strength, as well as endurance capacity in elderly subjects. The purpose of this study was to investigate the possible relationship between serum steroid hormones, strength and aerobic performance in older men.

Macroprolactinemia in women with hyperprolactinemia: a 10-year follow-up.

Objectives: To determine the frequency of macroprolactinemia in a cohort of hyperprolactinemic women, describing 1) the association of macroprolactinemia with clinical variables and morphological changes in the pituitary gland and 2) clinical status and prolactin levels after 10 years of follow-up.

Design: Blood samples were obtained from 32 patients for hormonal assessment. Treatment with cabergoline or bromocriptine was interrupted 3 months before the determination of serum prolactin and macroprolactin.

Neuromuscular, hormonal, and metabolic responses to different plyometric training volumes in rugby players.

The purpose of this study was to investigate the effect of different volumes of plyometric exercise (i.e., 100, 200, or 300 hurdle jumps) on acute strength and jump performance and on the acute hormonal and lactate responses in rugby players.

Molecular aspects involved in swimming exercise training reducing anhedonia in a rat model of depression.

Patients suffering from depression frequently display hyperactivity of the hypothalamic-pituitary-adrenal axis (HPA) resulting in elevated cortisol levels. One main symptom of this condition is anhedonia. There is evidence that exercise training can be used as a rehabilitative intervention in the treatment of depressive disorders.

Effects of a highly palatable diet on lipid and glucose parameters, nitric oxide, and ectonucleotidases activity.

Obesity has reached epidemic proportions worldwide and is stimulated by the ready availability of food rich in fat and sugar (highly palatable diet). This type of diet increases the risks of obesity-associated pathologies, such as insulin resistance and cardiovascular disease. Nitric oxide, a potent endogenous vasodilator, is decreased in these pathologies, mostly as a result of insulin resistance.
