In injured and diseased tissues, changes in molecular and cellular compositions, as well as tissue architecture, lead to alterations in both physiological and physical characteristics. Notably, the electrical properties of tissues, which can be characterized as bioelectrical impedance (bioimpedance), are closely linked to the health and pathological conditions of the tissues. This highlights the significant role of quantitatively characterizing these electrical properties in improving the accuracy and speed of diagnosis and prognosis.

Background/objectives: Low energy availability (LEA) can cause impaired reproductive function, bone health issues, and suppressed immune function, and may result in decreased performance and overall health status. The purpose of this study was to investigate adaptions of body composition, blood status, resting metabolic rate, and endurance performance to gain more comprehensive insights into the symptoms of LEA and the adaptive effects in the athlete population (active women (n = 11) and men (n = 11)).
Methods: Three treatments were defined as 45 (EA45, control), 30 (EA30), and 10 (EA10) kcal/kg FFM/day and randomly assigned.

Senescent bone tissue displays a pathological imbalance characterized by decreased angiogenesis, disrupted bioelectric signaling, ion dysregulation, and reduced stem cell differentiation. Once bone defects occur, this pathological imbalance makes them difficult to repair. An innovative synergistic therapeutic strategy is utilized to reverse these pathological imbalances via a conductive hydrogel doped with magnesium ion (Mg)-modified black phosphorus (BP).

There are limited studies on the phase angle (PhA) and sarcopenic obesity (SO) in the Chinese population. This study aimed to establish 50 kHz-PhA reference data for SO population, and to evaluate the correlation between 50 kHz-PhA and SO. A total of 10,312 participants including 5415 men and 4897 women were enrolled in this study, and their resistance and reactance at 50 kHz, and body composition parameters were measured a segmental multifrequency bioelectrical impedance analysis device (InBody 720).

The case report explores the effects of testosterone replacement therapy (TRT) on body composition, lean muscle mass, and fat mass, based on the dosage of TRT and exercise intensity in a 40-year-old male. The purpose of this case study was to evaluate the dose-response relationship of TRT and exercise on muscle hypertrophy and fat loss over an eight-month period, using a validated wrist-worn wearable fitness tracker to measure daily physical activity and heart rate (HR)-based exercise intensity. The patient, a trained male with 25 years of consistent exercise experience, reported notable declines in strength and increases in body fat despite maintaining a regular workout routine.
