purpose of the present study is to identify muscle imbalance regarding
force, supplemented by an imbalance of segmental muscle mass
(determined from the analysis of body composition), to create a
training program and apply it over five weeks, in order to obtain an
improvement of the maximum force in the weak muscles.
and Method: The study was conducted over a period of five
weeks, involving 20 junior handball players, between 17 and 19 years.
The evaluation of physical capacity of the athletes was made by
measuring isometric muscle strength for main muscle groups.
The determination of maximal force was made by using a
manometric digital dynamometer (Chatillon K-FCE-200, USA). The method
used for strength development was broad-based pyramid method. For the
deficitary musculature the after-tiredness method has been used.
Significant improvements of the force parameters were noticed
in: antagonistic muscle groups involved in the prosecution of
technical procedure (external rotation of the shoulder, arm, forearm
flexion, arm adduction), the musculature of the butterfingered member
(left elbow extension at the right handed and vice versa at the left
handed); muscle groups that were bended to exercises
involving new moves or with a greater repeating sequence
(exercises for the rotator muscles of the torso made in every workout).
Conclusions: The identification of muscle strength
imbalance completed by the imbalance of the segmental muscle mass
(determined from the analysis of body composition), allows the
elaboration of individual strength programs, in order to improve
specifically the strength and muscle mass, which will have as a
result the improvement of the players sport
