Effects of 50 Days Eggshell Membrane Ovometî Supplementation onBiomechanics Parameters and Subjective Pain Perception Among CrossfitAthletes. A Preliminary Study

The eggshell membrane has shown a positive effect on joint pain relief. In this study, several tests have been performed to measure the effect of Ovomet® supplementation on subjective perception and biomechanical variables to crossfiters before and after 50 days of administration. Pain perception questionnaires were performed in order to assess and demonstrate the protective or potentiating of Ovomet® effect on athletes' joints. In addition, we measured biomechanical variables such as muscle strength and power in knee extension, linear stiffness of the Achilles tendon (AT) by ultrasound, muscle stiffness through sensor in two different manoeuvers. Of all the biomechanical variables, the measurement of tendon stiffness by ultrasound, proves to be a useful tool to study the factors that can affect the joints, like our object of study, the effect of joint supplementation on athletes.
