Resistance training as a keystrategy for high-quality weightloss in men and women

Background: Preserving fat-free mass (FFM) during weight loss is critical for preventing sarcopenia and maintaining metabolic health. This study examined the effects of resistance training (RT), aerobic exercise (AR), and no exercise (NO) on body composition during a calorie-restricted diet.

Is There a Need to Reassess Protein Intake Recommendations Following Metabolic Bariatric Surgery?

Purpose of Review Protein intake is recognized as a key nutritional factor crucial for optimizing Metabolic Bariatric Surgery (MBS) outcomes by preventing protein malnutrition, preserving fat-free mass, and inducing satiety. This paper discusses the current evidence regarding protein intake and its impact on clinical outcomes following MBS.

The paradox of obesity with normal weight; a cross-sectional study

Objective: To evaluate the prevalence of excessive adiposity among normalweight individuals, and their cardiometabolic risk.

Cross-Validation of a New General Population RestingMetabolic Rate Prediction Equation Based onBody Composition

Abstract: Current prediction equations for resting metabolic rate (RMR) were validated in a relatively small sample with high-individual variance. This study determined the accuracy of five common RMR equations and proposed a novel prediction equation, including body composition.

Comparison of body composition assessment across body massindex categories by two multifrequency bioelectrical impedanceanalysis devices and dual-energy X-ray absorptiometry inclinical settings

Background InBody-770 and SECA mBCA 515 are multifrequency bioelectrical impedance analysis (BIA) devices, which are commonly used in the clinic to assess fat-free mass (FFM) and body fat (BF). However, the accuracy between devices in clinical settings, across different body mass index (BMI) groups remains unclear.

A novel body circumferences-based estimation of percentage body fat

Abstract: Anthropometric measures of body composition are often used for rapid and cost-effective estimation of percentage body fat (%BF) in field research, serial measurements and screening. Our aim was to develop a validated estimate of %BF for the general population, based on simple body circumferences measures.

תוספי תזונה ארגוגניים לספורטאים

נטילת תוספי תזונה נפוצה בקרב ספורטאים חובבנים ומקצוענים כאחד. חלק מתוספי התזונה נמצאו כמשפרי יכולת גופנית ואילו אחרים לא נמצאו כמשפרי ביצועים גופניים. לחלקם אף מיוחסות השפעות לוואי. תוספי התזונה בספורט מסווגים לקטגוריות בהתאם ליעילותם ובטיחותם: 1. תוספים שיעילותם הוכחה ונמצאו כבטוחים לנטילה; 2. תוספים העשויים להועיל; 3. תוספים שמוקדם מידי לקבוע את מידת יעילותם; 4. תוספים שלא נמצאו יעילים. במאמרנו הנוכחי, אנו סוקרים ארבעה תוספי תזונה מכלל התוספים המשתייכים לקטגוריה הראשונה "תו
