تأثير تدريبات بأرض رملية في تطوير بعض الصفات البدنيةللاعبين الشباب بكرة القدم

Abstract

The idea of training ground sand as resistance training , as
show its importance through the difficulty of movement on the floor
of sand , which produces due to increased relative movement
between the grains of sand, dry non- cohesive , forcing the player to
exert more force and effort to overcome this difficulty in movement ,
and lies this importance in determining the coefficient of friction
which is less on the surface ( ground ) compared to the sandy
surfaces ( ground ), herbal , and this in turn requires a double effort
from player to overcome this resistance.
As a result of the lack of studies and research on the exercises on
the sand , so it felt a researcher to do in a study to identify the impact
of training ( sandy lands ) in the development of some of the
physical abilities of young football players.
