Assessment of total body potassium in healthy Italian men.

Background: Whole-body (40)K counting is a valuable tool for assessing cellular changes in body composition with ageing.

Aim: The objectives of this study were to assess total body potassium (TBK) and body cell mass (BCM) differences with age, and to compare TBK and BCM between individuals with a body mass index (BMI) < 25 kg m(-2) versus > 25 kg m(-2).

Subjects And Methods: Body composition of 840 healthy Italian men, 18-70 years of age, was measured by whole-body counting of (40)K.

Effect of supplementation of calcium and vitamin D on bone mineral density and bone mineral content in peri- and post-menopause women; a double-blind, randomized, controlled trial.

Background: Osteoporosis is a serious global health problem for the future, that is why improving diagnostic methods and prevention of this disease could be helpful.

Objectives: To assess the effects of calcium supplementations combined with Vitamin D on bone mineral density (BMD) and bone mineral content (BMC) in a representative sample of peri- and post-menopausal women in a double-blind, a randomized, controlled trial was untaken.

Design: A total of 120 women aged over 45 were included in a randomised placebo-controlled, double-blind trial on the effect of a daily dietary supplementation of calcium and Vitamin D on bone mineral density and bone mineral content; over a 30-month period.

[Changes in body composition caused by intense physical training].

Purpose: To show the importance of the study of body composition in functional capacity evaluation of athletes who play professional football, during periods of very hard training (before the beginning of the championship), in order to appreciate every kind of adaptation to the training itself more precisely.

Materials And Methods: 18 semiprofessional football players, ages 18-32 yr., weight 75.

A new predictive equation to calculate resting metabolic rate in athletes.

Background: The purposes of the present study were: 1) to examine the accuracy and precision of seven published equations for predicting resting metabolic rate (RMR) in male athletes and 2) to develop a population-specific equation.

Setting: The study occurred during a non-intensive training period. The measurements were performed at the Human Physiology laboratory.
