Sexual maturation effect on physical fitness in girls: a longitudinal study
Journal Title: Biology of Sport - Year 2010, Vol 27, Issue 1
Abstract
The purpose of the present longitudinal study was to find associations between sexual maturation dynamics and improvement in performance of fitness tests. 34 11- to 13- year-old girls performed standing long jump, 20 m dash, shuttle run 4 x is related to 9 m, trunk forward flexion, squats in 30 s, sit-ups in 30 s, and Cooper 12-min running test at the beginning of observation, a year later, and two years later. Sexual maturation was assessed with the aid of breast development stages. When during a year girls transferred from the sexual maturation stage 2 to the stage 3, standing long jump results improved significantly. Transfer from the stage 4 to the stage 5 associated with the improvement of the trunk forward flexion.
