The studied subjects were primary school students. The analysis of the perceptual-motor potential at studied subjects shows that they develop normally, the same as their school mates their age. As for body awareness, we have noticed that the students who take part in other sport activities, besides the compulsory ones at school, are more aware of their bodies. The existence of some significant statistical differences among the body awareness indexes indicates a better awareness of the body, of body parts and of relating to different tasks. These are already aware of their bodies. This is according to Mucchielli quoted by Albu&Albu (1999), who said that body awareness progresses slowly until 11-12 years old and it is stress by practice and experiences. This can be a reason to explain the body awareness progress of the children who take part in more physical activities. Experts in child development suggest that the body awareness is an important issue in perceptual-motor development. Children know their bodies through changes in sensory-perceptual functions. These are the results of experiences in which the children are engaged (Sidentop&al, 1984)
