The role of core stability exercises in dynamic balance and the sport performance children of competitive elite female swimmers girl

Despite the widespread use of core stability training for stabilizing the core muscles of trunk, so far no study was carried out at the professional level, especially among the swimmers. The purpose of this study was to study the role of core stability training in dynamic balance and the sport performance of competitive female swimmers. In this quasi-experimental study the participants (female swimmers: age: 7-10 years, No=24) with a history of more than two years of professional activity in the Damash team (Tehran, Iran) were randomly selected and assigned into two control and experimental groups at 2017 year. At both pre-/post- stages the endurance of the trunk extensors, flexors and lateralis; the strength of the trunk muscles, dynamic balance and the performance of the participants were studied. The experimental group performed an eight week core stability training protocol. Comparing the mean pre-/post between the experiment groups for variables of the total endurance of the core stabilizing muscles, endurance of the trunk flexors, strength of the central region a significant increase ((p=0.016 and P=0.001, respectively) and decrease in swimming (50 and 100 m) speed was seen (P=0.001). The comparison of findings between groups showed a significant difference for the endurance of flexor muscles (P=0.031); right lateralis of trunk (P=0.034); total endurance of trunk muscles (P=0.018); strength of the core region (P=0.036) and the swimming (50 m) speed (p=0.001) under the influence of training protocol.
Discusion & Core stabilizing muscle training can considerably alter the strength and endurance of trunk muscles and result in a better balance and exercise performance, especially in child-age range swimmers.
