Abstract
The stage of adolescence is the stage in which the young person’s life is affected by physiological factors influencing their activity and their personality clearly. The characteristics of adolescence differ because of many factors, including individual genetics, climate and nature. Physical growth at this stage is characterized by speed with imbalance where the body grows very quickly and inconsistently. This stage is characterized by the change in the growth of height and weight, and the effect of this is reflected in the breadth of the shoulders and the chest, the length of the trunk, the circumference of the buttocks and the length of the legs, and the physical growth reaches its maximum speed at the age of 12 years for girls and the 14 years for boys. Material and methods. This study includes the age group 12-15 of the school’s students. The study was conducted on a sample of about 70 pupils who were randomly selected, 32 of whom were girls and 38 boys from the total sample of the school’s total number of 355 students. We used anthropometric measurements through which we extracted the percentage of body masses as well as determined body patterns. In order to determine the effect of feeding, we monitored the nutritional behavior of the research sample for a month and recorded the contents of the meal (breakfast, lunch and dinner for the last day plus other random times). Results and discussion. The study showed that muscle mass was proportional to its eating behavior. Muscle mass is the predominant sample for both sexes. Its percentage is the highest among other ratios, as it was confined between 42.25% and 56.03%, followed by bone mass by 20.53% and 25.19%, and finally fat mass by 8.29% and 11.01%, respectively. The results showed that the amounts of substances rich in carbohydrates were those that govern the daily diet. The average meal during a month was estimated at 84.75% through eating large quantities of bread, couscous and pasta. Both height and weight were in direct proportion to age, and by tracking the growth path from the age of 06 to 15 years, the proportion of both cholesterol and triglycerides were proportional. With the mass ratio, the cholesterol ratio in the blood was estimated to be between [1.09-1.58] g / l, and the triglyceride ratio was between [0.78-1.02] g /l. Conclusion. Having analyzed and discussed the results, and similar studies, we concluded that muscle mass was the dominant one for the research sample on the bone and fat masses

The changes in the somatotype components during growth in adolescents between 10 and 19 years can provide vital information for growth patterns, the timing, and rate of sexual maturation [1]

Summary
The changes in the somatotype components during growth in adolescents between 10 and 19 years can provide vital information for growth patterns, the timing, and rate of sexual maturation [1]. The somatotype corresponds to the estimation of the corporeal shape and its composition, which is expressed in three numbers that correspond to the components obtained during the embryological development: endoderm, mesoderm and ectoderm, altogether corresponding to the morphological characteristics of the subject as a whole [3]. A study analyzed anthropometric characteristics and somatotype of young players at different ages (14-18 years) from teams of the First Macedonian league (n=486) and compared the results with data from general population. Obtaining players at 14 years showed significant lower values of muscle and fat mass. They discovered that in all age soccer groups mesomorph component of the somatotype dominated. Athletes presented smaller values of the fat and endomorphic component and greater muscle and mesomorph component in comparison with general population [4]
