Abstract:
The aim of the study was to identify differences between trained and untrained subjects with respect to body composition and motor abilities. Two groups of subjects participated in the study: young judoists (110 boys and 56 girls) and their untrained mates (115 boys and 60 girls), aged 11 to 16 years, all from the Province of Vojvodina, Serbia. Young male judoists proved significantly better than their untrained mates in repetitive and static strength exercises, running speed, whole-body coordination, and had lower subcutaneous fat tissue of the upper arm. Young female judoists were significantly better in repetitive strength, whole-body coordination and plate tapping, chest girth and stretched upper arm, and also had lower subcutaneous fat tissue of the upper arm and back.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
