Muscular balance of the upper limb and trunk and its relation to the performance of certain skills in gymnastic

Abstract

The importance of research lies in determining amount of strength between the muscles as well as muscular balance between the both limbs of the player and the one limb and between the trunk and abdomen and the importance of research in identifying an important aspect and attention toward the distribution of nerve signals between the limbs of the body and between working and counteracting muscles, the search problem summarized is that most trainers train some muscles with more attention than other muscles such as agonist or antagonistic muscles and this affects the muscular balance especially between the agonist muscles in the performance of the athlete, which makes the performance and the movement do not go smoothly correctly. The aim of the research was to identify the correlation value between muscle strength of the limbs and the balance of the limbs of the body and the skill of jumping the hands and jump the hands on the jumping platform. The research community included Al-Qadisiyah University's players in Gymnastics for the academic year (2017-2018). There were 10 players representing the research sample. Photography of technical performance of skills 1- Evaluation of the performance of the hand jump. 2- Evaluation the performance of the jump of the hands on the jumping platform. The researchers photographed the players when the two skills were performed on the gymnasium hall and then the video was shown on experts and specialists in the Gymnastics field and the tests were then conducted to evaluate the muscle strength of the body parts as follows: 1- Biceps muscles of the arm (right, left) 2- Half Squat muscles of the arm(right,left) 3-Muscles of abdominal flexion 4-Muscles stretching back Data were statistically processed by extracting the value of the correlation coefficient between the variables of the study and through it we can conclude the following: 1 - All the muscles of the players of the University of Qadisiyah (under study) in Gymnastic balanced whether between the left and right limbs or one limb of the body (Biceps - Half Squat) as well as the muscles of the trunk. 2-The strength of the back muscles have a big role in the performance of the skill of the hand jump in the players of the University of Qadisiyah team in Gymnastic.
