“…Similar results were obtained in our own studies, with a statistically significant correlation between a higher level of PhA and higher levels of physical activity among students. Skeletal muscles are the largest conducting tissue in the body, so the value of the phase angle is strongly correlated with FFM [54].…”

Background: The aim of this study is to determine the relationship between selected components of body composition and the phase angle specified by bioelectrical impedance analysis, depending on the level of physical activity among students. Materials and Methods: The study group consisted of 484 university students from Krosno. The diagnostic survey method (IPAQ-SF), measurements of highs, and analysis of body composition components (BIA) were used. The relationship between variables was determined using the χ2 test, the V-Kramer coefficient, and Spearman’s rho coefficient. Results: University students in physical education demonstrated the highest level of physical activity and the lowest incidence of excessive body mass. Among the participants, 28.1% did not engage in any physical activity, or their level was insufficient. The PhA level was correlated with lean body mass and muscle mass. The correlation between higher levels of PA and PhA values was statistically significant, as was the relationship between self-assessment of physical fitness and the level of PA determined by IPAQ-SF. Conclusions: Preventive actions and educational programs, especially about spending leisure time in active ways, should be particularly targeted at students of disciplines with a significant amount of sedentary classes.

“…BIVA emerged as a helpful method to track changes in hydration, cellular integrity and health via PhA quantitation, a compound of two raw BIA determinations, resistance and reactance, removing the potential bias introduced by the use of predictive equations. 62 Since oxidative stress and chronic inflammation have the potential to damage cellular structures, PhA can be viewed as an expeditious index of cellular integrity, health and hydration, thereby being useful in inflammation identification and prediction of adverse health outcomes. 63 Sex, age, extra-to intracellular water ratio, fat-free mass and BMI reportedly affect PhA values as do obesity-associated multimorbidity.…”

“…PhA is a composite appraisal combining resistance and reactance to operate as a global marker that reflects a patient's nutritional and inflammatory state. 62,64 Furthermore, it is a real-time, low-cost, reliable surrogate marker of cell membrane integrity for oxidative and inflammatory alteration screening. 63 The lack of standardization in the acquisition and processing of images represents a concern.…”

“…In this context, novel techniques have emerged, due to their availability in health centres and straightforward reproducibility, namely phase angle (PhA) retrieved from bioelectrical impedance vector analysis (BIVA) and nutritional ultrasound. BIVA emerged as a helpful method to track changes in hydration, cellular integrity and health via PhA quantitation, a compound of two raw BIA determinations, resistance and reactance, removing the potential bias introduced by the use of predictive equations 62 . Since oxidative stress and chronic inflammation have the potential to damage cellular structures, PhA can be viewed as an expeditious index of cellular integrity, health and hydration, thereby being useful in inflammation identification and prediction of adverse health outcomes 63 .…”

“…Due to the enormous potential of body composition analysis to improve the diagnosis and care of patients, its routine incorporation and implementation in practice is urgently needed and prompts this call to action to enrich the classical anthropometric determinations and BMI‐centric approach with morphofunctional assessment whenever possible (Figure 2). PhA is a composite appraisal combining resistance and reactance to operate as a global marker that reflects a patient's nutritional and inflammatory state 62,64 . Furthermore, it is a real‐time, low‐cost, reliable surrogate marker of cell membrane integrity for oxidative and inflammatory alteration screening 63 …”

Adolphe Quételet, a 19th‐century Belgian sociologist and statistician, pioneered the incorporation of statistics into social sciences. He initiated the development of anthropometry since he was interested in identifying the proportions of the ‘ideal man’. He devised a ratio between weight and height, originally termed the Quételet Index, and today widely known and used as the body mass index or BMI. In 1835, he demonstrated that a normal curve accommodates the distribution of human traits articulating his reasoning on human variance around the average. Quételet's long‐lasting legacy of the establishment of a simple measure to classify people's weight relative to an ideal for their height endures today with minor variations having dramatically influenced public health agendas. While being very useful, the limitations of the BMI are well known. Thus, revisiting the beyond BMI paradigm is a necessity in the era of precision medicine with morphofunctional assessment representing the way forward via incorporation of body composition and functionality appraisal. While healthcare systems were originally designed to address acute illnesses, today's demands require a radical rethinking together with an original reappraisal of our diagnosis and treatment approaches from a multidimensional perspective. Embracing new methodologies is the way forward to advance the field, gain a closer look at the underlying pathophysiology of excess weight, keep the spotlight on improving diagnostic performance and demonstrate its clinical validity. In order to provide every patient with the most accurate diagnosis together with the most appropriate management, a high degree of standardization and personalization is needed.
