We examined the impact of aerobic exercise on morphological characteristics and agility in elementary school children. Anthropometric characteristics of the subjects were as follows: longitudinal skeletal dimension (body height, as well as the lengths of upper and lower extremities), circular skeletal dimension and body mass (mean circumference of the chest, the circumference of the thigh of an stretched leg, maximum circumference of the calf, body mass) and subcutaneous fat (skin thickness of the abdomen, thigh and calf). The agility was estimated by the envelope test, side steps and a eight with bending. For statistical analysis we employed the basic methods of descriptive statistics, while the discriminatory power of measurements was estimated by calculation of skewness and kurtosis of the data. Canonical correlation analysis was applied to explain the structure of the relationships between the two sets of data. The results of the analysis on this sample suggest that there is a strong linear relationship between morphological characteristics and agility at a multivariate level.

The extent and frequency of sports injury is often influenced by a variety of exogenous and endogenous factors, including poor physical fitness muscular imbalance, anatomical abnormalities, poor nutrition, and periods of intensive growth. The competing ability must be carefully estimated after injury, taking into account the nature and type of injury, the pain sensitivity as well as the time that passed from the injury. This is usually accomplished by the comparison with the uninjured limb, as well as with functional examinations. We evaluated the frequency and the type of injury in 112 sportsmen in Kosovska Mitrovica. Our results indicate that accurate evaluation of competing ability after injury is an important preventive measure in further sports activities.
