The purpose of the paper is to highlight the dynamics of the training means throughout the general preparatory period of junior weightlifters III (9-12 years old). In this regard, a study of case was organized in “Rapid” Sports Club of Bucharest, Weightlifting Department. The study was conducted over a period of 3 months (from January to March 2021) corresponding to the general preparatory period. The subject of the study was one 12-year-old athlete, with a training experience of 6 months, who has not participated in competitions so far. The means of technical and power training (front and back squats, pulls, snatch, clean and jerk, bent over rows) were planned and monitored along the 12 micro-cycles (MiC) of training. The duration of the training sessions was 120 minutes. The results of the study reveal the following values: in MiC 4 the share of the technical training is 30% (116 reps) and the share of the power training is 70% (284 reps); in MiC 8 – 35% technique (175 reps) and 65 % power (325 reps); in MiC 12 – 40% technique (240 reps) and 60% power (360 reps). Regarding the means of technique, in the MiC-s 4 and 8 there were used 60% technical means for snatch and clean & jerk and 40% for snatch and clean & jerk without split; the MiC 12 had a share of 70% for technical snatch and clean & jerk and 30% for snatch and clean & jerk without split. As for the means of power, the MiC-s 4 and 8 used 50% front and back squats, 40% pulls in snatch and clean & jerk and 10% bent over rows; the MiC 12 used 60% front and back squats, 30% pulls in snatch and clean & jerk and 10% bent over rows. Therefore, we can draw the conclusion that an optimal relationship between the technical training means and the power training means during the general preparatory period of Junior III weightlifters (9-12 years old) contributes to the increase of muscle strength and the improvement of the technical performance.
