The study aimed to identify the effect of combined (physical - skill) exercises using a designed device on developing certain shooting skills for basketball players under 18 years old. The researchers used the experimental approach on a sample of 14 players, divided into an experimental group and a control group.To achieve the study's objectives, the researchers designed a basketball shooting development device, which consists of a rotating base, poles, and a main body, in addition to an electronic system that rotates the device towards the player approaching the proximity sensors.The researchers also prepared a set of physical and skill exercises using the designed device. These exercises were applied to the experimental sample for eight weeks, with three training sessions per week. The researchers concluded that the combined exercises using the designed device had a positive impact, leading to the superiority of the experimental group over the control group.
