Swim training attenuates the adverse remodeling of LV structural and mechanical properties in the early compensated phase of hypertension.

Aim: Investigate to what extent low-intensity swim training for six weeks counterbalances the adverse remodeling due to the advance of pathological hypertrophy in the left ventricle (LV) structural and mechanical properties in the early compensated phase of hypertension in male SHR.

Main Methods: Four-month-old male SHR and Wistar rats were randomly divided into Sed (sedentary) and Ex (exercised) groups. The exercised rats were submitted to a swimming protocol (1h/day, 5times/week, no additional load) for six weeks.

Thermoregulatory responses of children exercising in a hot environment.

Objective: To review possible peculiarities in biological mechanisms related to responses of thermoregulatory and specific sweat glands in exercise performed by children in hot environments.

Data Sources: Review of 47 articles published between 1960 and 2011 in the electronic databases MedLine and SciELO Brazil using the following key-words: 'children', 'heat', 'sweating', 'thermoregulation', 'sweat gland', and 'exercise', alone or in combination, in addition to a doctoral thesis about the subject.

Data Synthesis: Pre-pubertal sweat rate during exercise is lower than among adults.
