At the Hyrox International Championships held in China, Australian athlete Joanna Wietecki won despite having a bowel movement accident during the competition. As this video spread on social media, hygiene controversies and criticism of the organizers' response arose. Online, it was revealed that Joanna had drunk 'Duowuz', a traditional Chinese fermented beverage, during her preparation for the competition, leading to speculation that this could be the cause of the bowel movement accident. However, a direct causal relationship between Duowuz and acute diarrhea has not been confirmed. Duowuz is a drink that is loved and hated in China due to its unique smell and taste.
