Carbon fiber insoles and jumps: do they boost sprint and jump for active men?

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study is an observational cross‑sectional comparison that measures performance with and without VKTRY carbon fiber insoles. Male participants aged 18–30 who exercise regularly complete vertical jump and sprint tests under both conditions, with objective metrics collected by the My Jump Lab app and subjective perceptions gathered via a Likert-type survey. Key outcomes include jump height, flight time, sprint time, maximum speed, and perceived usefulness. The goal is to see if the insoles provide an immediate performance benefit and how athletes perceive their effect on performance. Results may inform training practices and the use of ergonomic devices in amateur athletics.
