Objective: This research aims to follow the evolution of the morphological characteristics of young volleyball players aged 15-17 during a sporting season.
Methodology (12) young male volleyball players aged 15 to 17 participated in this present study, they are volleyball players licensed in the volleyball league of the wilaya of Mila and from the WRSM teams (WidadRiadhi Sidi-sghier Mila ) ; EST (Entente Sportive Tadjenanet)
Our experimental protocol consisted of defining the morphological parameters of the sample studied by taking anthropometric measurements.
Results: Existence of a significant difference for the variables (Height), (Height Sitting, Upper Limb, Arm, Lower Limb, leg, Foot), (Forearm, Thigh), (Height Sitting, Upper Limb, Arm, front -arm, Lower limb, Thigh, Foot), (Leg), (Chest EXP/REST, Arm Rest/Stretched), (Biacrom, Elbow, Wrist), between the control phases (C01&C02), and the difference in favor control (C02).
On the other hand, for the variables (Weight), (hand), (INSP Chest, Stomach, Pelvis, Forearm, Thigh, Leg), diameter variables (Thorax, Bicretal, Knee, Ankle), body composition variables ((% ) Fat Mass, (%) Lean Mass), there is no significant difference between the control phases (C01&C02).
