Relationship between dynamic balance, functional movement and muscle

Abstract

The functional movement screen is an easily administered and noninvasive tool for identifying weaknesses and asymmetry during exercises and daily activity. Also the bilateral asymmetries inflexibilityand in Y Balance Test have been associated with injuries. However, relationships among these attributes are unclear especially in young adults. The aim of this study was to determine the association between dynamic balance using the Y-Balance Test (YBT), functional movement using the functional movement screen (FMS) and muscle lengths using a standard goniometer in a young adults. Secondary aims were to investigate whether this parameters differed between male and female. One hundred twenty-three healthy people (male: n=68, age=21.49 +/- 1.47 years; female: n=55, age=20.98 +/- 1.67 years) participated in the study. Spearman correlation analysis was used to determine the relationship between muscle lengths and FMS, and the YBT. There were positive correlations between the muscle lenghts and the YBT(.197<r<.352). There were significant relationships between FMS and muscle lengths (hamstring and iliopsoas). Functional movement scores were not significantly different between male and females (p>.05) when considered as total scores. However, females performed significantly better than male on the shoulder mobility (p=.004) and straight leg raise (p=.000) but poorer than male on the trunk stability push-up (p=.001) and deep squat (p=.000). We conclude that muscle length in young, male and female can effect in FMS and dynamic balance.
