This study investigates the effects of a 9-month PA intervention on physiological characteristics and motor and cognitive skills in preschool children. (2) Methods: Preschool children (n = 132
Fitness profile of young female volleyball players
BACKGROUND: Factors that influence performance in volleyball, in terms of motor skills, refer to muscle power, speed and agility. This study aimed to examine the abilities and physical characteristics of female volleyball players in terms of age and player specialization. METHODS: A total of 35 subjects (junior and cadet age), participated in this study. Subjects were assessed for body height, mass, spike and block reach, and body composition. Vertical jump, standing broad jump, spike and block jump were tests used to measure leg power. The running speed was evaluated with a 20-m single-sprint effort. The change of direction speed was assessed with a T-test, the sprint 9-3-6-3-9 m forward-b…
Anthropometric characteristics and vertical jump abilities by player position and performance level of junior female volleyball players
Although absolute jump heights should be considered an important factor in judging the performance requirements of volleyball players, limited data is available on age-appropriate categories. The purpose of this study is to determine the differences in specific anthropometric characteristics and jumping performance variables in under−19 female volleyball players in relation to playing position and performance level. The sample of subjects consisted of 354 players who prepared for the U19 Women’s Volleyball European Championship 2020 (17.4 ± 0.8 years, 1.81 ± 0.07 m, 67.5 ± 7.1 kg). Playing positions analyzed were setters (n = 55), opposites (n = 37), middle blockers (n = 82), outside hitter…
