| ABSTRACT | |||
| The purpose of the present study was to investigate the influence
of different degrees of opposition on ball velocity in the jump throw in
elite, amateur and adolescent team handball players. Thus, one hundred and
nineteen elite, amateur and under 18 team handball players performed jump
throws under three different conditions: 1) without opposition, 2) with
the opposition of the goalkeeper and 3) with the opposition of the goalkeeper
and a defensive player. The degree of opposition was found to have a negative
effect on ball velocity in all three groups (p < 0.001). Furthermore,
the level of competition had a positive effect on ball velocity (p <
0.001). However, no interaction was found between the level of competition
and the degree of opposition on ball velocity (p = 0.178). The findings
of this study indicate that an increase of external stimuli probably influences
throwing kinematics and thereby maximal ball velocity. However, experience
does not seem to be a factor that can reduce the influence of these external
stimuli. Key words: Team handball, jump throw, ball velocity, defence. |
