Acute dietary nitrate supplementation improves dry static apnea performance

Highlights ► Dietary nitrate supplementation increases dry apneic duration in well trained apnea divers. ► Dietary nitrate supplementation reduces resting pre-apneic blood pressure. ► Dietary nitrate supplementation reduces arterial O2 desaturation during sub maximal apnea. ► Dietary nitrate supplem...
