ASSESSMENT OF THROWING ARM ANGLES IN VERTICAL JUMP SHOT OF HANDBALL PLAYERS

Abstract

Background: The kinematic analysis of jump shot with reference to the analysis of the
release angle of different joints of the arm helps us to understand how to improve the
maximal force muscles produced where the motor actions are performed at the instant frame
of release.
Objective: The main objective was to investigate, assess and compare the angle of release of
different joints of the right arm among handball players of under-14 and under-18.
Methodology: Thirty (30) right handed national-level handball players, fifteen players (15)
of each under-14 and 18 years of age were selected. For measuring the angle of release of
different joints of the right arm (wrist joint, elbow joint and shoulder joint) at the instant
frame of the handball released, a high-speed action camera (GoPro 12) was used to capture
the frame in this study. Kinovea, a video annotation tool designed for sports movement
analysis was used to record and further investigation analyzing the angle of the joints of the
right arm.
Result and Conclusion: Significant differences were found between the two groups of their
means comparison of the shoulder joint and the elbow joint (p<0.05), but there was no
significant contrast in the wrist joints of the two groups, which were considered for this study
(p>0.05). Following the result of the study could give a few conclusions regarding the speed
generated by the groups and injuries that could be identified in future by studying the range
of movements.
