The myofascial connections described by various authors influence to varying degrees the stability, body posture, balance, coordination and motion control. Loss of structural or functional stability disrupts motor functions. Difficult control of a damaged joint weakens balance, stability, muscle patterns and body alignment. Functional instability occurs in a healthy structure but forces negative compensations in generating and controlling force. The dysfunctions of the above-mentioned features negatively affect on motor functions. Research has shown that an injury in strength sports depends on the quality, type and intensity of the training program, and that different types of physical activity cause different physiological changes with different health effects. For this reason, the epidemiology of related injuries with practicing strength sports is still incomplete. OBJECTIVE: The aim of the study is to assess the influence of symmetrical and asymmetrical movement patterns of the upper limbs and body during strength activity on biomechanical deviationsin individual planes of the joints of the lower extremities. Th}, abstract={e presented relationships may contribute to a deeper understanding of the epidemiology of lower limb injuries. MATERIAL AND METHODS: The research was carried out at the Rehabilitation Center in Rzeszów in the period 06.2019 - 02.2020.90 men born between 1980 and 1990 were examined, divided into three groups. A group of athletes, 30 men participating in strength competitions, regularly trained at least 4 times a week. Group of amateurs - a comparative group A - the study involved 30 men taking training loads occasionally - up to 3 times a week. Static group - comparative group B - the study involved 30 men with a sedentary lifestyle, without strength activity. RESULTS: Differences in the functions of the lower limbs were demonstrated under the influence of asymmetric training, increased training of the upper limbs. Different joint mobility was also found in a given plane in the test and comparative groups. CONCLUSIONS: The dominant effort of the upper limbs in strength training influenced the functions of the lower limbs in the frontal plane. The asymmetric nature of sports activities differentiated the ranges of rotation of the joints of the lower extremities. Occasional physical activity helps to maintain the three-dimensional symmetry of the knee joints.}, type={Praca doktorska}, keywords={strength sports, functional condition of the lower limbs}, }
