Evaluation of ColdZyme Mouth Spray for the Protection against Common Cold in Elite Athletes to Reduce Unwanted Absence from Training and Competition

Abstract

This study evaluated the protective effect of ColdZyme on common cold in-fections in elite athletes from three different sports (biathlon, ice-hockey and handball), and assessed the level of reduction in corresponding sick days. The biathlon team (n = 11) and the ice-hockey team (n = 29) significantly reduced the average number of sick days by 51% respectively 67% compared to histor-ical data. No historical data on sick days was available for the handball team but 76% of those who experiences a cold during the study period reported lit-tle or very little impact on training and competition. Conclusion: Using ColdZyme may be an easy and practical way for elite athletes to protect them-selves against the common cold and to prevent corresponding unwanted ab-sence from training and competition.
