The accelerated social changes of recent decades (urbanization, digitalization, transformation of dietary patterns, increased sedentary behavior, and chronic stress) have profoundly reconfigured the health profile of populations. Today, we face not only infectious or deficiency diseases, but a silent epidemic of non-communicable diseases (NCDs): obesity, type 2 diabetes, sarcopenia,...

From anthropometry to DEXA, we analyze the strengths and limitations of each of the body composition methods. Why bioimpedance spectroscopy (BIS) is the missing physiological piece in modern clinical practice.

The physiological transition of menopause Menopause is a period in women's lives characterized by a significant number of physiological changes, the main cause of which is the progressive decrease in hormone secretion by the ovaries, particularly estrogens¹. It generally lasts 4 to 5 years at a median age of 51...

Training Load and Physical Fitness The benefits of physical activity and chronic physical exercise on health are well known, with numerous musculoskeletal, cardiovascular, metabolic, and cerebral adaptations. Paradoxically, acute exercise induces significant physiological stress: increased acidity or mechanical constraints on the muscular and skeletal systems that are objectively detrimental to...

Definition of Phase Angle In bioelectrical impedance analysis (BIA), the phase angle is a raw bioelectrical parameter obtained in two ways: By measuring the angular difference between the voltage U and current I curves. From the formula: arctanleft(frac{X_C}{R}right) times left(frac{180}{Pi}right) The calculation of this parameter suggests that the phase angle would not...

Introduction Aging represents a growing challenge in public health, including the early detection of malnutrition in older adults. This condition, frequently underdiagnosed, negatively impacts functionality, quality of life, and clinical prognosis. Traditional methods of nutritional assessment, focused on body mass index (BMI), medical history and anthropometry, are insufficient to identify...
