Abstract
Limited evidence exists on how segmental external load is distributed during linear running
and how it varies with speed, training intensity, and individual differences. This
study examines the external load profile across six body segments in elite female futsal
players during linear treadmill running, focusing on the effects of speed and training
zone, as well as individual variability. Eight elite players, including six outfield players
and two goalkeepers (mean age 23.9 ± 3.4 years, height 164.96 ± 4.22 cm, body mass
60.31 ± 4.56 kg), performed an incremental test and were measured using six WIMU PRO™
inertial sensors. The sensors recorded segmental PlayerLoad, speed, and training zones.
Data were analyzed using Linear Mixed Models. The most important results show significant
interactions between body location and speed and between body location and training
zone (p < 0.001), with intraclass correlation coefficients (ICC) ranging from 0.437 to 0.515.
These results indicate variability among players and specific and asymmetrical segmental
load patterns. These findings offer practical insights for tailoring individualized training
strategies that optimize performance and reduce segment specific overuse injuries.
