Purpose of this study ; to examine the effect of core stabilization program for gymnasts.The individuals has to divided into 3 groups. First group will consist individuals who are not interested in any sports and don't do any exercises during 8 weeks. Second group people can do gymnastics twice a week but can't do core stabilization exercise. Third group is consist people who regularly do gymnastics and also do 30-45 minutes core stabilization exercises as well.

Core stabilization is an ability which describes the control of movements in kinetic chain during changes in positions at terminal segments . Hodges and Richard examined muscle activations during movements and found that some muscles which are responsible from core stabilization start to activate before extremity muscles.These results can support the hypothesis of movements come from control and stabilization through core. The body or as specified lumbopelvic area can contain spine cord and pelvis stabilization at work of active, passive and neutral. All these systems are work together for one purpose/Passive system contain bonds, vertebrates and invertebrates , neutral system consist nerve and central nerve system . In active system there are muscles within tendons ,core muscles can be describe as double cylinder and it's the investigator's body's power supply. This double cylinder's front consist abdominal muscles and back of it consist paraspinal muscles, above area is diaphragm and down is from pelvic and hip muscles.

Performance of muscles show the capacity of its work done.There are three important subtitles to show this performance , force , power and endurance . Especially for professional athletes if the performances are not enough or one of them can be not consist it means they effected in immortal ways. One of these elements , muscle endurance is the resistance of muscle for the stretching for a time and stay constant in this situation and show resistance ability to fatigue. This is needed to lot of activities during the day however in sport activities we need balance as top level , coordination and improve performance as an element.There is a defense which says that improvement of muscle endurance has an importance role for making stronger muscles and at the same time it is also be shown as making muscles strong. In order to make stronger muscles ACSM (American College of Sports Medicine) suggested to exercise 3 times a week by making each exercise 2-4 sets . For improvement of force and power we need to exercise up to 8-12 sets and for muscle endurance we need 15-20 repeated sets.

Gymnastics; a multidirectional sport which consist of speed , force , endurance , flexibility , agility , power and balance. If you want to be successful and make this sport as a professional you need to have suitable physical appearance and an ability. In this situation it is important to make core muscles powerful. In recent years the exercises of core stabilization has an importance role to prevent or decrease backache and also it is used as a concept of therapy for improving physical relevance and performance. It is shown in may researches that core stabilization can affect the balance to the specific movements in gymnastics as well as core endurance and if it is not enough it affect the performance in bad ways and may be increase the risk of injury.

In literature there are researches which show positive correlations between core stabilization and performance. For this reason, gymnastic coaches has to add core stabilization in their exercise list. In this care core endurance and performance which is related to balance can be directly increase. We seen that there is a lack of strengthening core stabilization program in literature. Purpose of this study ; to examine the effect of core stabilization program for gymnasts.The work consist amateur 7-9 years old children. The individuals has to divided into 3 groups. First group will consist individuals who are not interested in any sports and don't do any exercises during 8 weeks. Second group people can do gymnastics twice a week but can't do core stabilization exercise. Third group is consist people who regularly do gymnastics and also do 30-45 minutes core stabilization exercises as well.Gymnastic training is going to be given by a professional coach from Turkish Republic of Nothern Cyprus Gymnastic Federation twice a week as one hour. Generally these training consist the movements to improve the power and flexibility of individuals plus as a professional meaning which consist specific things like ; bridge , glider , eagle , spagat , circle , flick flack and perpendicular stance. It is worked for making strongest protocol core stabilization in different source of literatures. As a result they confirm of a progress in two weeks as exercising in 8 weeks. This progress consist 30-45 minutes\ day and 3 days\ week. Before every training they need to have 10 minutes warming exercises. This include 5 minutes running and 5 minutes stretching of all groups of muscles. All the exercises have to be combined with breathing.

Inclusion Criteria:

• 7-9 years child gymnasts
• At least 3 months regularly attending children
• Girl children

Exclusion Criteria:

• People who has at least 6 months extremity and lack of spine surgeon
• Neurological ,vestibular and people who has vizuel problems except breakage.

There are differences in physical and physiological between genders. These differences can effect directly to the performance. Also after puberty these differences are become evident. From infant period parents , teachers , coaches can separate boys and girls according to their physical activities which can be affect their fat ratio of body or muscle texture.This is the reason that man can be successful at short which needs force and woman can be successful at gymnastics which needs flexibility.
