The purpose of this study was to evaluate the changes in body fat percentage and aerobic capacity in professional soccer players, after the implementation of a specific 4-week training regimen during the transition period. Fifty-eight professional soccer players of the Greek Premier National Division were separated in experimental (n = 38) and control groups (n = 20). Body composition and maxim...

BACKGROUND Recent studies have revealed that body mass index (BMI) inversely influenced serum glycated albumin (GA), which may cause an underestimation of GA-monitored short-term hyperglycemic control. OBJECTIVE This study was to investigate the association between anthropometric variables (BMI and waist circumference (W)) and accurate adiposity variables (percentage of body fat (%fat), fat m...

BACKGROUND Blood pressure (BP) increases with age and obesity. We have assessed the relative contribution of age and fatness to BP regulation in a healthy population investigated by nurse practitioners. MATERIAL AND METHODS Preventive investigation and counseling was offered at the entrance hall of the regional authority´s office in the town of Nitra by 2 nursing specialists who investigated ...

background: it seems that weight gain and body composition changes occur during the first year of college . the aim of this study was the comparison of body composition among freshmen medical sciences students one term after entering rafsanjan university of medical sciences , south east of iran.   materials and methods: all freshmen medicine (n = 73) and nursing- midwifery students (n = 57) of ...

The objective of the paper was to determine body composition and somatotype of male Greco-Roman wrestlers grouped by different weight categories and level of competition. Twenty three contestants (aged 24.9±5.5 years, training experience 13.7±5.8 years) were examined during their competitive period. They were divided into heavier (n=12) and lighter weight categories (n=11).Twelve of them took p...

OBJECTIVE To monitor the seasonal body composition alterations in 18 lightweight rowers (six females, 12 males) across a rowing season incorporating preseason, early competition, competition, and postseason. METHODS Subject age was 23.1 (SD 4.5) years, height 170.8 (5.6) cm (female, 23.5 (3.5) years, 180.5 (2.7) cm (male). Body weight, fat mass, and fat-free mass (FFM) were assessed using dua...

UNLABELLED The body mass index (BMI) is used to assess nutritional status. The result in athletes may be overestimated due to increase in muscle mass. OBJECTIVE To assess the usefulness of fat mass index (FMI) and lean mass index (LMI) determination as indicators of nutritional status and to compare the results with BMI. MATERIAL AND METHODS We studied 28 amateur rugby players, male. After ...

The effect of relative body fat mass on exercise-induced stimulation of lipolysis and fatty acid oxidation was evaluated in 15 untrained men (5 lean, 5 overweight, and 5 obese with body mass indexes of 21 +/- 1, 27 +/- 1, and 34 +/- 1 kg/m2, respectively, and %body fat ranging from 12 to 32%). Palmitate and glycerol kinetics and substrate oxidation were assessed during 90 min of cycling at 50% ...

The β-2 and β-3 adrenergic receptors (ADRB2 and ADRB3) are thought to play a role in energy expenditure and lipolysis. However, the effects of the ADRB2 glutamine (Gln) 27 glutamic acid (glutamate) (Glu) and ADRB3 tryptophan (Trp) 64 arginine (Arg) polymorphisms on weight loss remain controversial. The aim of this study was to investigate the effect of these polymorphisms on changes in weight a...

BACKGROUND Police officers are often required to undertake physically demanding tasks, like lifting, dragging and pursuing a suspect. Therefore, physical performance is a key requirement. METHODS Retrospective data for 76 male police officers (mean age = 39.42 ± 8.41 years; mean weight = 84.21 ± 12.91 kg) was obtained. Data included anthropometric (skinfolds, estimated percentage body fat, le...
