Effects of Carbon Fiber Insoles on CMJ and Sprint Performance

Overview

This study evaluates the effects of VKTRY carbon fiber insoles on vertical jump and sprint performance in moderately active men. Participants will perform tests with and without insoles, assessing both objective performance and subjective perception using a Likert-type scale.

This study aims to analyze the effects of using carbon fiber insoles (VKTRY) on physical performance in explosive tasks, specifically vertical jump (countermovement jump - CMJ) and sprinting, in moderately active young adults. The increasing use of ergonomic technologies in sports has sparked interest in devices such as these insoles, which promise to increase mechanical efficiency and propulsion during athletic movements, thanks to the rigidity and energy return capacity of carbon fiber. Study Design: The study design is descriptive, observational, cross-sectional, and comparative. The sample will consist of men aged 18 to 30 years with regular sports participation (2-4 days per week). Each participant will perform vertical jump and sprint tests under two conditions: with and without carbon fiber insoles. Measured Variables: The variables evaluated will include jump height (cm), flight time (ms), sprint time (s), maximum speed (km/h), and subjective perception via an adapted Likert-type survey. Objective evaluation will be conducted using the validated My Jump Lab application. Expected Implications: The study seeks to determine whether these insoles significantly influence immediate sports performance, both in terms of physical parameters and athletes' perception. Results could have practical implications for training, injury prevention, and the use of ergonomic aids in amateur athletes.
