Physical activity loads influence upon the state of musculoskeletal system of middle-distance runners
Middle-distance runners aged 14-17 are frequently subjected to having disorders of the musculoskeletal system. Statistics reveals 61% of foot deformation, 50% of pelvis asymmetry, 63.9% of lower limbs length asymmetry. Sportsmen having foot deformation (celosias), influenced by the physical activity in different directions tend to significantly reduce the height of the foot arches. The last impairs the ability of foot depreciation. Having musculoskeletal system deviations in functional status, the track and field athletes (middle distance runners) are revealed to have lower limbs muscle and back in rest tone increase after being engaged in physical activities. This data attests the expressed response of the neuromuscular system.
