Abstract:

Introduction:
Improving performance in handball requires ongoing research. How young handball players learn the tactics of the game is one of the main factors in improving future performance. The content of the tactical and technical thinking and actions of beginners is related to their play potential and increases both quantitatively and in terms of difficulty as player's progress through the levels of play. (Mihăilă Ion, 2012), this study assessed a strategy to using hypermedia for improve performance of complex motor skills in children.

Methods:
A group of 38 male subjects (mean age 12.5; max-min =12-13 years) volunteered for the study. All were regional handball players from two teams belonging to the same club.Their mean experience in handball was 3 ±1.3 years. The 38 male subjects were divided into two groups matched on training Units with complex motor performance skills tests. The study was conducted according to the declaration of Helsinki and was approved by the local Ethics Committee.
This study was performed during the competitive season (from September to May) in a 12-week period from October to December 2012. During this period, both groups were trained by normal exercises program, all the subjects trained 3 times each week for handball. Practice handball sessions lasted 70 min and usually consisted of various skill activities contained complex motor performance and the experimental group was training with normal training program in addition to units of hypermedia 3 times each week for 70 minutes. 12 complex motor performances exercises were used by two groups. Each exercise was repeated from 6 repetitions with the intervention by the coach to motivate players to perform better and correct mistakes. A successful performance was evaluated as achieving the goal of the training in the shortest possible time and without mistakes.
The training was provided to the treatment group 3 sessions a week, and hypermedia units in the other 3 days as sturdy hypermedia, Sunday practices in court for two groups with the same coach and so on. Because the handball players belonged to the same club and were trained by the same coach, their training schedules were fairly well synchronized.

Measurements:
Complex motor performance skills tests from the first of the playground:
Test 1 :( pass -straight running-catch ball throw running-one dribble-jump shoot)
Test 2 :( short pass-moving - catching at head height -2 dribbling-feint-shooting)
Test 3 :( dribbling-short pass-catching ball in jumping-zigzag dribbling-overhead shot)
Test 4 :( straight dribbling -catching ball-long pass-straight moving–catch-shoot).
All players from both groups were carefully familiarized with the test protocol of complex motor performance skills tests. Each test contained some complex motor skills (different types of movements, passes, catch ball, dribbling, feint, and shots) the player’s time was measured. All players made three attempts for each test, with two minutes rest between each attempt and 10 minutes rest between each test. The time of attempts for each player to do the test correctly and only the best time for each player was recorded.

Results:
Indicate to the existence of significant differences between control group and experimental group, where the percentage of performance mistakes was decreased and time was improved.
