Purpose/Hypothesis: The purpose of this study is to examine if static stretching, dynamic stretching, or no warm up would better affect static balance, dynamic balance, Star Excursion Balance Test (SEBT), and Balance Error Scoring System (BESS).
Subjects: Fourteen active females between ages 18-25. Exclusion criteria: LE injury preventing participation in competition or practice for at least 1 day in the last 12 months, head injury in the past 12 months, score of level 1 (low) on the IPAQ, chronic ankle instability, history of ankle surgery, current or past neurological deficits, and non-English speakers.
Methods/ Materials: Fourteen healthy, female participants, ages 18-25, were randomized into either a static stretching, dynamic stretching, and no warm-up protocol for each visit. This was followed by performing the following balance balance examinations in a randomized order: Postural sway as measured by the Prokin, SEBT, and BESS, during each appointment on 3 consecutive days.
Types of Data Analysis Used: A one-way repeated measures ANOVA was conducted to compare scores on stretching protocols on SEBT, Postural Sway and BESS. Paired-sample t-test was also analysed between conditions.
Results: No significant difference was found in any of the conditions, on any measure with the exception of postural sway measures between the no warm-up and dynamic stretching protocol t=.815, p<.05. The dynamic stretching subjects demonstrated increased sway in medial-lateral directions. Wilks' Lambda scores were all insignificant with Standard Deviation of movement Forward/Backward approaching significance with Wilks' Lambda=.698, F(2,12), p=.115, multivariate partial eta squared=.302.
Conclusions: In athletes with a history of concussion No significant difference was found between any of the conditions, with the exception of a significant difference between the dynamic stretch protocol and the no stretching protocol on the postural sway measures. The dynamic stretching subjects demonstrated increased postural sway in medial-lateral directions.
