Influence of the Exercises with Sports Hammock on Functional Durability of the Postural Stability Muscles

Natalia Usheva, Silviya Filkova


INTRODUCTION: `Good posture` is the position of the body that imposes minimal stress on muscles and negligible load on joints in order to maintain balance. This is achieved by keeping the muscle balance necessary for proper development and functioning of the locomotor system.

AIM: The aim of this study is to determine the influence of exercising with sports hammock on functional endurance of the postural stability muscles.

MATERIALS AND METHODS: The survey was conducted between February 2014 and December 2015 among 200 children aged between 5 and 7 years in the city of Varna. The test of Matthiass, the test of Kiel and the test of sustained balance were used for the assessment of the functional endurance at the beginning as well as at the end of the survey. For one half of the children (n=100), exercising with sports hammock was applied, while the rest of the children remained as a control group. Descriptive methods and hypothesis testing (Student`s t-test) were used for data analysis.

RESULTS AND CONCLUSIONS: The differences between the initial and final means in all tests of endurance for the children of the intervened group are positive and statistically significant, i.e. all the tests demonstrate improvement (p<0.0001). Upon completion of the test of Kiel on static and strength durability of the abdominal muscles the best improvement is observed in the experimental group (exercises with sports hammock): +0.94 seconds (p< 0.0001). The improvement is significant also in comparison with the results of the children from the control group.
