A comparative study between the players the artistic gymnastics and acrobatic in most important of the kinematics to skill back handspring on floor exercise

الملخص EN

Researchers and from through reconnaissance on the levels of gymnastics teams noticed a deficiency in some kinematics variables and especially with szczecin acrobatic in Poland when performing backward handspring as an of movements Preliminary mastery that an arrow to the integration acrobatic movements so the researcher studying the situation to determine the most important weaknesses in the performance of skill by the two groups (Szczecin acrobatic and Szczecin gymnasts).

The research sample consisted of ten players per team five players took a sample way intentional the survey was conducted by camera Sony type speed it 60 frame per second The data was processed through motion analysis software (Kenova, DartFish and Logger Pro) and extracted the data through statistical Package Minitab 16 calculated values the statistical significance between the two groups and appeared significant differences statistically significant .Researchers concluded that the increase in rising in CoM and shorter time and extending the joints of the body and increase the angular velocity phases performance is one of the good Performance in the backward handspring the requirements of either of the recommendations was that the biomechanics analysis of individual gymnasts is helpful both for reporting to coaches and to provide detailed feedback that will lead in discovering potential reasons for superior performance.

The data obtained indicate that differences in expertise are relatively easy to quantify through the analysis making communication between coaches and gymnasts simpler, easier and more efficient
