摘要

The aim of this study was to compare locomotor activity profiles of Brazilian topclass female soccer players competing at distinct age brackets (under 17 [U17], under [U20], and senior). External match load of 14 U17, 14 U20, and 17 senior female soccer players competing in 6-7 full official international matches were assessed using global positioning systems. Total distance covered, distance covered in high intensity (15.6-20 km.h(-1)), distance covered in sprints (sprint: >20 km.h(-1)), number of accelerations (Acc) >1 m.s(-2), decelerations (Dec) >(-1) m.s(-2), and Player Load generally increased across the age brackets (U17 < U20
