This study aimed to identify the effect of harmonic exercises on some variables of sensory-motor perception and the level of technical performance of the skills of serving and receiving the ball in table tennis. The experimental method was used for its relevance to the nature of the study. The study sample consisted of 42 students of the racket games course students at the Department of Sports Sciences and Physical Activity. They were divided into two equal groups, 21 for the experimental group and 21 for the control group. The harmonic exercises were applied for 8 weeks, with one lecture per week. Each lecture lasts for 100 minutes, and it's divided into three parts (warm-up part, for about 10 minutes; main preparation part, for about 80 minutes, which is divided into 35 minutes for physical preparation and 45 minutes for technical preparation; and the final part, for about 10 minutes). After analyzing and tabulating the data, the researchers concluded that practicing harmonic exercises led to an improvement in some variables of the sensory-motor perception and the level of technical performance of the skills of serving with the forehand and backhand and receiving the table tennis ball. Also, the students of the experimental group exceeded the students of the control group in reducing the percentage of estimation errors for the factors of power, time, and estimated distance in the techniques. These findings have practical implications for table tennis training, as they demonstrate the effectiveness of harmonic exercises in improving sensory-motor perception and technical performance. Based on the results of the study, the researchers recommend applying the harmonic exercises since they improve the students' variables of sensory-motor perception and their level of technical performance in the skills of serving with the forehand and backhand and receiving the table tennis ball.
