Body surface area is a predictor of maturity status in school children and adolescents.

Background: Generally, Body surface area (BSA) changes significantly during growth and maturation. These increases portend a possible relationship between body size as determined by BSA with maturational status in children and adolescents.

Objective: To determine the relationship between maturity status (MS) obtained by non-invasive anthropometric methods and body surface area (BSA) in children and adolescents of both sexes in a regional population of Chile.

Assessing quality of life with SarQol is useful in screening for sarcopenia and sarcopenic obesity in older women.

Background: Health-related quality of life (HRQoL) may be impaired in the presence of sarcopenia. Since a specific quality of life questionnaire became available for sarcopenia (SarQol), cutoffs to screen for this condition have been proposed, prompting the need to assess them in different populations. Due to the lack of consensus on diagnostic criteria, the tool has not yet been analyzed in screening for sarcopenic obesity.

Fat infiltration and muscle hydration improve after high-intensity resistance training in women with sarcopenia. A randomized clinical trial.

Background: Resistance training is recommended for preventing sarcopenia, but the benefits for the quality and quantity of muscle mass are uncertain.

Objective: To assess the effects of high-intensity resistance training (HIRT) on clinical and magnetic resonance imaging (MRI) parameters in women with sarcopenia.

Methods: A researcher-blinded randomized clinical trial was conducted.

Resistance training of peripheral muscles benefits respiratory parameters in older women with sarcopenia: Randomized controlled trial.

Purpose Of The Research: Ageing entails a decrease in muscle mass and strength, known as sarcopenia, which also affects respiratory function. Physical exercise is an appropriate intervention to treat both conditions. This study aims to assess the efficacy of high-intensity resistance training (HIRT) on clinical parameters of respiratory function and health-related quality of life (QoL) in community-dwelling older women with sarcopenia.

The Role of Imaging Biomarkers in the Assessment of Sarcopenia.

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.

[Lifestyle and physical condition factors associated with gender-specific BMI in Spanish preadolescents].

Obesity has become one of the most serious health problems in our society and is associated with a multitude of conditions and complications at puberty. Through this descriptive, cross-sectional study we intended, first, to know the differences by gender in lifestyle and physical condition variables, and second, to know the determinants related to lifestyle and physical condition for a Spanish population aged 10 to 12 years with a medium socioeconomic status. The variables analyzed were BMI, physical condition variables (agility, flexibility, and cardiorespiratory capacity), and health habit variables (quality and frequency of food, physical activity, sedentary lifestyle, and sleep duration).

EFFECTS OF AN INTERVENTION PROGRAM (HHP) ON THE PROMOTION OF HEALTHY HABITS IN EARLY ADOLESCENCE.

Background: it is vital to monitor and promote healthy lifestyle habits in early adolescence, as it is a time of changes when future lifestyle habits are formed.

Methods: a study was conducted to find out the effects of a Healthy Habits Program (HHP) in children between the ages of 10 and 12 years (N = 158). The study included an intervention group (IG) (n = 90), which participated in the HHP for 8 months, and a control group (CG) (n = 100).

[Benefits of a home-based physical exercise program in elderly subjects with type 2 diabetes mellitus].

Objective: To analyze the effects of a home-based physical exercise program on quality of life, metabolic control, and anthropometric and biochemical parameters in people over 60 years of age with type 2 diabetes mellitus.

Methods: Eighty-four Spanish patients aged over 60 years were finally randomized to participate in a home-based, combined physical exercise program (aerobic and anaerobic exercises) or to receive conventional treatment for diabetes. At 6 months, effects on quality of life (EuroQoL questionnaire).

[An ambulatory physical exercise program improves in the short term weight and quality of life of obese post-menopausal women].

Objectives: To evaluate the effects of an ambulatory physical exercise program on the quality of life, anthropometric and biochemical parameters in obese post-menopausal women.

Methods: One hundred and six obese post-menopausal women were randomized to take part in an ambulatory program of physical exercise (aerobic and anaerobic), or to receive conventional information about diet and exercise. After three months, effects on quality of life were evaluated (test Euroqol, Rosenberg and subjective evaluation of health), weight, BMI, waist perimeter and fat mass, and biochemical parameters.
