Background: Taping is one of the conservative intervention methods used by health professionals for a long time to provide mechanical support for the musculoskeletal system. However, there is insufficient evidence to demonstrate its effect on Dynamic® taping. The purpose of this study to investigate how Dynamic® taping affected vertical jump and medial longitudinal arch (MLA) height in adolescent volleyball players with a low MLA. Methods: In the study, 23 female athletes participated with the mean age of 15.22±1.54 years. On the first day, athletes who were evaluated without a tape and they received Dynamic® taping the next day. Then they were re-evaluated with the taping on. All athletes jumped on eight different surfaces, first with shoes and then barefoot (without shoes). The distance of navicular drop was evaluated with the navicular drop test and vertical jump height was measured with the device VERT® (Mayfonk Athletic, USA). For the statistical analysis, the software SPSS version 22.0 for IBM (SPSS Inc., Chicago, Il, USA) and dependent groups student’s t-test was used. P-value accepted as 0.05 and cases where P < .05 were considered statistically significant. Results: The distance of navicular drop both in the right and left feet decreased in a statistically significant (P < .05) extent following Dynamic® taping. Comparing the vertical jump heights on eight different types of floor surface, before and after taping, with and without shoes, it was found that there was no statistically significant difference for all cases (P > .05). Conclusions: This was the first study to investigate the effectsg of Dynamic® taping on vertical jump and MLA height in adolescent volleyball players with low MLA height. As a result of the study, it was found that Dynamic® taping did not have a statistically significant effect on the vertical jump height, but it decreased navicular drop distance at statistically significant levels. Dynamic® tape application can be used as an easy-to-apply practical treatment agent to support the MLA in asymptomatic adolescent athletes with an increasing navicular drop. Trial registration: Before starting the study, approval from Gazi University Ethics Commission dated 20/11/2018 and numbered 14574941-050.99- 153747 was obtained.
