A review was carried out following the Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) checklist.

Does predicted age at peak height velocity explain physical performance in U13-15 basketball female players?

Background: The aims of the study were (1) to identify the physical fitness and basic anthropometric characteristics of Polish female basketball players aged 13-15 years, (2) to show the effect of maturity timing on the performance in motor tests and basic body composition parameters, (3) to identify the index that contributes most to the prediction of performance in the tests of speed, jumping ability, agility, and endurance.

Methods: The sample included 904 female Polish players (U13-15). In part 1, maturity timing category distribution were examined within across age-groups.

Injury Prevalence of the Lower Limbs in Handball Players: A Systematic Review.

Lower limb injuries are frequent in handball and a serious hindrance to athletic performance. The aim of this systematic review was to synthesize the available research on the prevalence of lower limb injuries in handball players according to sex and competitive level. According to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis, 19 studies were selected after a systematic search and selection process of three digital databases: Scopus, PubMed, and Web of Science.

Are the Player Selection Process and Performance Influenced by Relative Age Effect in Elite Women's Handball?

The relative age effect (RAE) is a phenomenon present in team sports, but it does not influence each gender to the same extent. This study aimed to examine the RAE and its relation to performance in international women's handball competitions (2017/18 World Championships). The sample was composed of 1,096 female players distributed into three categories: youth or under 18 (n = 369); junior or under 20 (n = 328) and senior (n = 399).
