Abstract


Introduction: Endurance athletes have a high incidence of upper respiratory tract infection (URTI). ColdZyme® Mouth Spray (ColdZyme) is a CE-marked medical device in the form of a mouth spray that forms a barrier in the throat against common cold viruses. Aim: The aim of this study is to assess the effects of ColdZyme on URTI incidence and symptom ratings in endurance athletes under free-living conditions. Methodology: The methodology involved a prospective, open label pilot study. Design & Participants: Thirty Five endurance-trained, competitive athletes were randomized to control (no treatment) or ColdZyme. They were monitored over the study period (December 2017 - February 2018) via training and illness symptom logs (Jackson common cold questionnaire). total of 35 completed (n=17 control; n=18 ColdZyme). Results & Discussion: At least one episode was recorded during the study period in 91% of all participants (94% control, 89% treatment). Fifty episodes were recorded in total over the study period with no difference between groups in the mean incidence rate (episodes/person: 1.4±0.7 Control, 1.6±0.9 Treatment, P=0.266). Episode duration was 10.9±10.2 days in Control and 8.3±6.3 days in Treatment (P=0.098). When use compliance was examined, those in the treatment group with good compliance to the product instructions for use (IFU) were observed to have significantly lower (P=0.038) episode duration (7.1±6.6 days). Conclusions: ColdZyme did not influence self-reported URTI incidence. However, the duration was significantly lower in the treatment group but only when the device is used in accordance with the manufacturer IFU.
