The study aims to develop specific physical abilities and assess their impact on the skill performance level of Uchi-Komi and Nage-Komi in judokas under 16 years old.  The authors employed the experimental method using a pre-post test design for two groups (experimental and control), as this design is appropriate for the research objectives and hypotheses. The sample was purposively selected from judokas at El-Gomhoria Sports Club in the Menoufia region, registered with the Egyptian Judo, Sumo, and Aikido Federation for the 2023-2024 season, totaling 24 players. The results demonstrated a significant improvement in physical fitness tests and skill performance levels for Uchi-Komi and Nage-Komi among judokas. The experimental group exhibited superior results compared to the control group. Post-test comparisons between the two groups revealed statistically significant differences in skill performance and physical abilities, favoring the experimental group. The computed t-value exceeded the critical t-value at a 0.05 significance level, confirming the effectiveness of the training program
