Reactive strength index (RSI) is a measure of explosive power calculated from vertical jump height divided by ground contact time. Resulting RSI values range from 0-5 m/s with higher numbers indicating greater power. High RSI values are obtained with minimal ground contact times and maximal vertical jump heights. Research has investigated RSI as an assessment for athletic performance; however, no known prior research exists on a training intervention to improve RSI. The main objective of this quantitative research design was to determine the effectiveness of an individualized force-velocity (F-V) intervention on RSI improvement. Eight NCAA division 1 American football athletes volunteered for the research design. At the conclusion of three weeks of three days per week specific F-V intervention, 1x3 change score ANOVA revealed no statistically significant differences amongst the control and intervention groups based on p = .05. Additionally, this design examined improvements in general athletic abilities, countermovement jump, and 10-yard sprint performance as a result of RSI improvements. 1x3 change score ANOVA for both countermovement jump and 10-yard sprint performance also indicated no statistically significant difference between groups based on p = .05. Finally, this study evaluated the validity and reliability of a new jump measurement device compared to a force plate. ICC statistics revealed a high level of validity for the two devices, with an average measure of .931. Recommendations based on the findings include increasing the length of F-V intervention, and increased specificity of F-V intervention.
