BIVA and anthropometric assessment of youth water polo players

Twenty-four young water polo players (age: 13.30yrs ± 0.55), took part in the study. To be included, participants needed to have consistently trained over the past year and competed in the regional championship. Exclusion criteria included having no injuries or clinical conditions at the time of the study, not being on medication, and not following any special dietary plans (e.g., hypo- or hyper-caloric diets).
Data were collected before and after a typical training session aiming to i) characterize young water polo players in terms of anthropometric and bioelectrical profile and according to the maturity offset and ii) provide information on hydration changes after training, using the bioelectrical impedance vector analysis.
Dataset includes demographic details (such as years of practice, weekly training frequency and duration, and other sports previously or currently practiced), anthropometry (including basal measurements such as stature, body mass, and sitting height, girths, and skinfolds), bioelectrical values (such as raw resistance and reactance), and derived body composition (body mass index, waist to height ratio, fat mass) and maturity offset (peak height velocity, adult stature) values.
