Influence of Dietary Nitrate on Time Trial Performance in Swiss Paracycling Athletes
- Conditions
- Exercise Nutritional Physiology
- Registration Number
- NCT02454049
- Lead Sponsor
- Swiss Paraplegic Research, Nottwil
- Brief Summary
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.
- Detailed Description
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.
