STUDY REGARDING THE BIO-MOTOR CAPACITY OF DIVISION “A” MALE TEAM HANDBALL PLAYERS
This paper presents an observational study on the level of the bio-motor ability recorded by nine male team handball players belonging to the Stiinta Bacau Sports Club, at the beginning of their training period. For assessing the performance, we chose the "15 jumps" drill, performed using both legs, only the right leg, and only the left leg. As an assessment device, we used a DELSYS Myomonitor IV 16 channels electromyograph. The methods we used in this study were: the study of the specialized literature, the testing method, the statistical-mathematical method, and the analysis method.
The analysis of the recorded values has shown several aspects. The distribution of individual values for the average unit power (PU), found between 4.21 W/kg body and 6.06 W/kg body, with an average of 5.27 W/kg body, for the two-leg take-off, emphasizes the fact that the nine male players have different training levels and performance possibilities, but these are favorable for getting good athletic results. The take-off height (H.f), or the spring, has individual values between 45 cm and 32 cm, with a group average of 39 cm. Five players have individual values higher than the average group value, which shows good strength and explosive power in the lower limbs. Regarding the repetition speed (V.rep.), the individual values in six players are better than the average group value (of 0.18 s), which shows a general high level of performance speed that leads to better results during competitions. Two of the players recorded lower values for the average power (4.21 and 4.54 W/kg body), and a deficit in speed (0.24 and 0.21 s), while two players recorded a very good speed (0.13 and 0.14 s), supported by a good average unit power (5.99 and 6.06 W/kg body). Regarding the strength-speed qualities, an improvement is needed, but there is also a necessity for improving the performance speed. The energetic variability coefficient values for the two-leg take-off, which shows the player's ability to control his movements, were comprised between 1.56% and 4.30%, with an average of 2.83%, which shows the possibility of obtaining good results during competitions. The structural variability coefficient (CVS) values, showing the player's ability to control and anticipate the contact with the floor, the ball, or the opponent, and it shows that two of the athletes (ID and GM), with values of 18.05 and 13.32, present a very high risk of injury. The first hypothesis stating that the male team handball players have different levels of training and different performance possibilities was confirmed. The second hypothesis stating that the values for strength, spring, and speed show that the training must be oriented towards increasing the performance speed and towards a certain diversification was confirmed.
