Special nutrition intervention is required for muscle protective efficacy of physical exercise in elderly people at highest risk of sarcopenia.

Progressive loss of muscle mass and strength is a physiological consequence of aging, and without interventions, it usually deteriorates into sarcopenia. In this study, the hypothesis that combined special nutritional-physiotherapeutical intervention to prevent or reverse this biological deterioration in elderly people was tested. The effects of the regular resistance muscle training (PT, n = 17) alone and the combined exercise + special nutrition therapy containing whey protein and vitamin D (PT + NT, n = 17) were monitored for 3 months in 34 elderly patients (12 men and 22 women; mean age: 66.

Arteriolar biomechanics in a rat polycystic ovary syndrome model - effects of parallel vitamin D3 treatment.

Unlabelled: To clarify the effects of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS) on arteriolar biomechanics in a rat model and the possible modulatory role of vitamin D3.

Methods And Results: The PCOS model was induced in female Wistar rats by ten-weeks DHT treatment. Arteriolar biomechanics was tested in arterioles by pressure arteriography in control as well as DHT- and DHT with vitamin D3-treated animals in contracted and passive conditions.
