Physical activity highly impacts the neuroendocrine system and hormonal secretion. Numerous variables, both those related to the individual, including genetics, age, sex, biological rhythms, nutritional status, level of training, intake of drugs or supplements, and previous or current pathologies, and those related to the physical activity in terms of type, intensity, and duration of exercise, or environmental conditions can shape the hormonal response to physical exercise. The aim of this review is to provide an overview of the effects of physical exercise on hormonal levels in the human body, focusing on changes in concentrations of hormones such as cortisol, testosterone, and insulin in response to different types and intensities of physical activity. Regular monitoring of hormonal responses in athletes could be a potential tool to design individual training programs and prevent overtraining syndrome.

Purpose: To investigate the longitudinal association between chronic pain and decline in activity of daily living (ADL) among community-dwelling older adults aged ≥ 60 years.
Methods: In this systematic review of prospective longitudinal studies with narrative synthesis, a comprehensive literature search was conducted using PubMed and Embase using free-text words and MeSH terms on February 3, 2025. Longitudinal studies that quantitatively assessed ADL at two or more time points and pain at least once were included.

Background: Brief measures of 24-hour movement behaviors are needed to easily evaluate their durations. The present study investigated the criterion validity and test-retest reliability of a brief self-report instrument to assess 24-hour movement behaviors.
Methods: A paper-based self-administered questionnaire was used to assess sleep, sedentary behavior (SB), light-intensity physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) with four items in 35 healthy adults.

Background: During intense exercise, anaerobic metabolism predominantly produces energy in the body, resulting in lactic acid (LA) accumulation, which contributes to muscle fatigue and soreness and may also impair neurological and cardiovascular functions. In endurance sports, the lactate threshold (LT) is a key indicator of an athlete's capacity to clear and utilize LA, directly influencing athletic performance and endurance. Therefore, LA detection is crucial for assessing the physical condition of both athletes and the general population, as well as for optimizing training programs.

Objective: To investigate the impact of objectively measured physical activity and stress on programmed hormone replacement therapy (HRT) frozen embryo transfer (FET) outcomes.
Design: Observational cohort study SUBJECTS: Patients undergoing standard HRT FET at a single academic center.
Exposure: Average daily step counts before and after FET as measured by FitBit Charge 5 wearable activity tracker.
