Background: Fluoride exposure traditionally produces improved dental health although evidence suggests it could result in adverse effects on other bodily systems which especially affect endurance athletes. This research investigates how endurance athlete respiratory health in Shijiazhuang and Tianjin is affected by fluoride exposure through their environment having elevated fluoride levels. Aim of the study: The research goal checks the effects of fluoride exposure on athletes' respiratory system health by evaluating fluoride concentrations in sports zones and monitoring athlete health symptoms as well as performance decline among sportsmen with elevated exposure to fluoride. Methodologly: This study used phenomenological qualitative research methodology alongside focus groups and participant diaries and semi-structured interviews to collect data from fluoridated areas endurance athletes. Athletes spanning between 18-45 years joined the study from running, cycling and swimming and triathlon backgrounds who were conducting endurance sports for at least three weekly sessions. The examined data underwent thematic analysis to extract important themes that connected fluoride contact with respiratory wellness. Findings: The research investigation uncovered three main sources of fluoride exposure through drinking water as well as fluoride in products and sports beverages. The athletes experienced respiratory symptoms comprising cough with shortness of breath and wheezing especially when their training intensity reached peak levels. The athletes detected more severe symptoms and declined performance because of higher fluoride exposure. Conclusion: The research indicates that endurance athletes face respiratory problems when exposed to high levels of fluoride. More studies are required to understand how fluorides affect athletic performance and to develop recommendations for public medicine and health practices.
