Influence of Dietary Nitrate on Time Trial Performance in Swiss Paracycling Athletes

The aim of this study is to investigate wether beetroot juice or sodium nitrate enhances time trial performance in Swiss paracycling athletes compared to the ingestion of a placebo supplement. Furthermore, the effects of beetroot juice and sodium nitrate on performance will be investigated in spinal cord injured and non-injured athletes.

About this study

The influence of dietary nitrate on performance will be tested performing a time trial on a handbike. The time trial will be the same as in the Paralympics 2016 in Rio. The subjects perform three trials and receive another supplement for each trial: beetroot juice with 6mmol nitrate, 6mmol sodium nitrate or plain water (placebo supplement). The time to complete the time trial will be the main outcome parameter.
