BMI-BFMNU: A structural index linked to fat mass
2021
Abstract Introduction: Body mass index (BMI) provides little information on body composition. For example, two people with the same BMI might have different body compositions. In this sense, the development of a new BMI able to provide body composition information is of clinical and scientific interest. The aim of the study was to suggest a new modified BMI formula. Material and Methods: A total of 108 subject, females 56 and males 52, 0-73 years old, in various physiopathological conditions were evaluated. Data were collected and processed by a program that through anthropometric measurements calculates classic BMI, volume, surface, V/S (that we can defined like a body-thickness “pse…
Effects of different circuit training protocols on body mass, fat mass and blood parameters in overweight adults
2017
Benefits of exercise are known for a long time, but mechanisms underlying the exercise mode recommendations for specific chronic cardiovascular diseases remain unclear. The aim of this study was to compare the effects of different circuit training protocols in order to determine which is the best for weight loss and for specific overweight- related disorders. Forty-five female sedentary overweight participants from 20 to 50 years (average 31.8±11.2) were enrolled and assigned to three different groups; each group was compared with a control normal-weight group. Three different circuit protocols were randomly assigned to each overweight group: aerobictone- aerobic (ATA), aerobic-circuit-aero…
Anthropometry and body composition of young soccer players
2022
Background: Body composition and other anthropometric measurements are important factors influencing the overall performance of an athlete. Together with motor coordination, physical fitness, physical, functional, and psychosocial conditions, as well as learned technique and tactics, a player's sports potential and probability of success can be determined. Aim of the study: Our study aimed to describe anthropometric variables and body composition of young soccer players of various ages. Materials and methods: A cross-sectional study was carried out among 61 young soccer players in the under-15, under-16, and under-19 categories. We used a bioimpedance analyzer to measure the following indic…
Effects of carbohydrate content on body composition during weight loss in female fitness competitors
2017
Introduction. Bodybuilders and fitness competitors are aiming to reduce fat mass and maintain lean mass during the competition phase. Low carbohydrate diets compared to low fat diets have claimed to be more effective in weight loss, but the results are still controversial. Low carbohydrate intake and high protein intake have been reported in bodybuilders during the diet, but the evidence of its effectiveness is limited. The aim of this study was to examine the effects of carbohydrate content on body composition during weight loss in female fitness competitors. Methods. A total of 50 female subjects participated in this study, 27 were competitors, and 23 were weight training stable controls.…

Strength Training Improves Metabolic Health Markers in Older Individual Regardless of Training Frequency
2019
The main purpose of the present study was to investigate the effect of frequency, thereby increasing training volume, of resistance training on body composition, inflammation markers, lipid and glycemic profile in healthy older individuals (age range 65-75 year). Ninety-two healthy participants were randomly assigned to one of four groups; performing strength training one- (EX1), two- (EX2), or three- (EX3) times-per-week and a non-training control (CON) group. Whole-body strength training was performed using 2-5 sets and 4-12 repetitions per exercise and 7-9 exercises per session. All training groups attended supervised resistance training for 6 months. Body composition was measured by dua…
CLA, “new nutrients”?
2005
International audience; Conjugated linoleic acid (CLA) refers to a class of positional and geometric dienoic isomers of linoleic acid. Chronic dietary supplementation with commercial isomeric mixtures sold as dietary supplements leads to a drop in fat mass in various species. The t10,c12-CLA isomer is responsible for this antiobesity effect.The reduction of fat mass is especially dramatic in the mouse, in which it is associated with a severe hyperinsulinemia, an insulin resistance and a massive liver steatosis. The origin of these adverse side effects and the putative chronology of events leading to CLA-mediated lipoatrophic syndrome are presented and discussed in this review. In Human, the…
Body composition with dual energy X-ray absorptiometry: from basics to new tools
2020
Dual-energy X-ray absorptiometry (DXA) in nowadays considered one of the most versatile imaging techniques for the evaluation of metabolic bone disorders such as osteoporosis, sarcopenia and obesity. The advantages of DXA over other imaging techniques are the very low radiation dose, its accuracy and simplicity of use. In addition, fat mass (FM) and lean mass (LM) values by DXA shows very good accuracy compared to that of computed tomography and magnetic resonance imaging. In this review we will explain the technical working principles of body composition with DXA, together with the possible limitations and pitfalls that should be avoided in daily routine to produce high-quality DXA examina…
The Role of Imaging Biomarkers in the Assessment of Sarcopenia
2020
Background: The diagnosis of sarcopenia through clinical assessment has some limitations. The literature advises studies that include objective markers along with clinical assessment in order to improve the sensitivity and specificity of current diagnostic criteria. The decrease of muscle quality precedes the loss of quantity, so we studied the role magnetic resonance imaging biomarkers as indicators of the quantity and quality of muscle in sarcopenia patients. Methods: a cross-sectional analysis was performed to analyze what MR-derived imaging parameters correlate better with sarcopenia diagnostic criteria in women of 70 years of age and over (independent walking and community-dwelling wom…
