Introduction

Triathlons, with their unique blend of swimming, cycling, and running, have become increasingly popular among athletes of all levels. For many women, participating in triathlons represents not only a personal challenge but also a celebration of strength and endurance. However, beneath the surface of these grueling competitions lurks a hidden risk that has been affecting female triathletes: Immersion Pulmonary Edema (IPED).

Triathlon, an exhilarating multisport event that encompasses swimming, cycling, and running, has gained immense popularity worldwide. Female athletes, in particular, have embraced triathlons as a testament to their physical prowess, resilience, and determination. However, beneath the surface of this dynamic sport lies a concealed threat that has been increasingly affecting female triathlon competitors: Immersion Pulmonary Edema (IPED) [1].

IPED is a condition characterized by the abnormal accumulation of fluid within the lungs during or after immersion in water. While it has long been recognized as a potential risk in water sports, its prevalence and impact on female triathletes have raised concerns in recent years. This article delves into the intricacies of IPED, aiming to unravel the hidden risk it poses to women in the world of triathlon [2].

Understanding immersion pulmonary edema

IPED is a condition that occurs when fluid accumulates in the lungs, causing breathing difficulties during and after submersion in water. It can affect swimmers, divers, and, indeed, triathletes who engage in open-water swimming as part of their race [3].

The rising concern

While IPED has long been recognized as a potential hazard in the world of water sports, its prevalence among female triathletes has raised concerns in recent years. The reasons behind this are not entirely clear, but there are several factors that might contribute to the increased risk:

Physiological differences: Some studies suggest that women may be more prone to IPED due to differences in lung physiology compared to men.

Training intensity: Female triathletes often push themselves to their limits during training and competition, which can exacerbate the risk of IPED [4].

Temperature fluctuations: The exposure to cold water during open-water swims in triathlons can further increase the risk of IPED.

Pressure to perform: The competitive nature of triathlons might lead female athletes to ignore warning signs and push through discomfort, which can worsen the condition.

Symptoms and consequences

The symptoms of IPED can range from mild breathlessness to severe respiratory distress. They often occur during or shortly after swimming, and can even lead to a medical emergency. Ignoring these symptoms can have serious consequences, including drowning or longterm lung damage [5].

Prevention and awareness

Preventing IPED begins with awareness and proper preparation: Know the Risk: Female triathletes should educate themselves about IPED and its symptoms.

Gradual acclimatization: Gradually acclimatizing to cold water and building up swimming endurance can reduce the risk [6].

Listen to your body: It's crucial to recognize any breathing difficulties or discomfort during the swim and take them seriously.

Seek immediate help: If any symptoms of IPED occur, it's vital to seek immediate medical attention.

Medical Assessment: Consider a pre-race medical assessment, especially if you have a history of respiratory conditions [7].

The way forward

Addressing the hidden risk of IPED in female triathlon competitors requires a collective effort from athletes, coaches, and event organizers.

It's essential to prioritize safety over competition and ensure that participants are well-informed about the risks they face.

Discussion

IPED is a rare yet potentially life-threatening condition that has been observed in various water-related activities, such as scuba diving and swimming. The underlying mechanism involves a combination of factors, including water pressure changes, cold water exposure, and strenuous physical activity, which can lead to increased pressure in the pulmonary circulation and subsequent leakage of fluid into the lungs [8].

Addressing the hidden risk of IPED in female triathlon competitors necessitates a collective effort from athletes, coaches, and event organizers. It is essential to prioritize safety over competition, ensuring that participants are well-informed about the risks they face. Emphasizing the importance of recognizing and responding to IPED symptoms can potentially save lives and enhance the overall well-being of female triathletes [9].

For athletes, it is important to be aware of IPE risk factors and how to manage them. They must also be able to recognize the symptoms of IPE before becoming incapacitated. Currently, no treatment has been proven to prevent the onset of IPE. Anecdotally, Nifedipine has been used as a prophylactic with some success in SCUBA divers. The long-term implications of repeated IPE incidents is unknown. All three triathletes detailed in this report have continued to train and compete successfully, however further study is needed before this can be recommended. Because the possibility of reoccurrence is high, the risk of drowning still exists [10].

Conclusion

Female triathletes are breaking barriers and pushing the limits of physical endurance, but it's crucial to be aware of the hidden risks that can accompany such dedication. Immersion Pulmonary Edema may be an uncommon condition, but its potential consequences are severe. By understanding the risk factors, recognizing the symptoms, and prioritizing safety, female triathletes can continue to excel in their sport while minimizing the hidden risks that lurk beneath the surface.

IPE is a serious environmental illness, likely triggered in triathletes by cold water immersion and exertion and may be exacerbated by other factors including gender, age, wetsuit tightness, and hydration status. Many patients experience multiple episodes of IPE, making previous history a major predisposing factor. IPE occurs in otherwise healthy males and females immersed in fresh or salt water. IPE generally occurs in colder water but has been described in warm water as well. Symptoms generally resolve quickly when patients are removed from water.
