Relationship between static and dynamic balance tests among elite Australian Footballers.
Research assessing the direct relationship between static and dynamic balance ability of athletes is sparse. The aim of this project was to determine the relationship between a static balance task on a firm surface with a stepping balance task on an unstable surface. Thirty-seven Australian male professional footballers participated in the study. The static test involved maintaining single limb stance on a force platform. The other balance test involved stepping on to a balance mat on top of the force platform and maintaining single limb stance. The centre of pressure was monitored and the maximum excursion in the medial-lateral direction was recorded and used as the balance value. It was found that the magnitude of the maximum centre of pressure excursion was significantly greater (53%) for the stepping balance task. There were significant but low correlations for the centre of pressure excursion values between the two balance tests for the right limb and average of both limbs. There was no significant correlation between the test values for the left limb. Only a small proportion of the variance could be explained by each test: 16% for right limb values, 7% for left limb values and 11% for the average of both limbs. Given the overall weak associations between the two balance test values, it was concluded that performance in the static balance test was not reflective of performance in the dynamic balance test. Attempting to infer dynamic balance ability based on static balance ability should be avoided.
