Correlation between wrist motor control and throwing velocity in young male handball players

n the handball game, scoring a goal by some way of shooting is concretized by the nu- merical advantage in the result of one team over another. Shootings as elements of hand- ball technique are the operators represented with the highest frequency in every handball training of young handball players. The aims of this research consist in determining the connection between throwing velocity and wrist motor control of the shooter’s hand in young handball players. The measurement was conducted on a sample of forty handball players from handball clubs: age of 11.23±0.54, body mass of 45.28±12.93 kg, and body height of 153.32±8.05 cm. The following variables where examined: age, body height, body mass, the velocity of movement of the ball under the basic shot from the spot, the velocity of movement under the basic shot of three steps from the ground, the velocity of move- ment under the jump shot from three steps, maximal strength of wrist palmar flexors, precise movement modulation during plantar and dorsal wrist flexion, precise modulation of submaximal force during plantar and dorsal wrist flexion. Basic descriptive parameters were calculated. Based on the correlation coefficients, the correlation of individual vari- ables of the studied sample was determined. A statistically important correlation between all three manners of shooting was found, as well as between the variables jump shot from three steps and the maximal strength of wrist palmar flexors (0, 41 p< 0, 05). According to the obtained results, it can be concluded that for young handball players aged 10–12 years the speed of the ball when shooting depends more on the palmar flexors maximum strength than on their coordinated work in fine movement control tasks.
