Resumen:
The aim
of this study is to evaluate the physical and physiological
load imposed on amateur football players in a simulated
game situation on different artificial turf systems. For that
purpose, 20 football players (21.65 6 3.10 year old) were
monitored with Global Positioning Systems and heart rate
bands during 45-minutes games on 4 selected artificial turf
systems. The results show more covered distance in highintensity
ranges on the system with lower levels of damping
and higher rates of rotational traction (p # 0.05). Likewise,
this system of artificial turf demonstrated a high number of
sprints (12.65 6 5.67) and more elevated maximum speed
peaks during the last part of the game (28.16 6 2.90
km$h21) in contrast to the systems with better damping
capacity (p # 0.05). On the other hand, the physiological
load was similar across the 4 artificial turf systems (p .
0.05). Finally, the regression analysis demonstrated a significant
influence of the mechanical properties of the surface
on global distance (15.4%), number (12.6%), and maximum
speed (16.6%) of the sprints. To conclude, the mechanical
variability of the artificial turf systems resulted in differences in the activit...
