Directing Attention Externally Produces Consistent Vertical Jump Assessment Results.

Recent research has demonstrated that consistent external attentional focus instructions produce more reliable jumping measurements compared to non-consistent focus of attention instructions. While previous research has examined the effects of different external attentional focus instructions, less is known about different external focus of attention instruction effects during a vertical jump. Given that previous work has demonstrated that consistent external focus of attention instructions produced reliable jumping estimations, we hypothesized that using multiple methods to direct attention externally would produce consistent vertical jump results. Using a within-participant design, college aged students ( = 35) completed two vertical jumps on a Vertec within five conditions. Each condition was provided different external directing instructions conditions (control; external-lower near, -upper near, -upper far, -unreachable far). Data were analyzed using a repeated measures analysis of variance (ANOVA). Results showed that jump heights in the control and external focus of attention conditions were not significantly different from one another, = .119. The findings of this study suggest there are numerous external focus of attention instructions that can be provided during a vertical jump producing consistent results.
