Final answer:
Track and field is considered unsafe for an athlete absent one kidney.
Step-by-step explanation:
The sport that is considered unsafe for an athlete absent one kidney is track and field. In track and field, athletes engage in high-intensity activities such as running, jumping, and throwing, which can put a significant amount of strain on the body, including the remaining kidney. The risk of injury to the lone kidney increases during these activities, making track and field less safe for individuals with only one kidney. I am not a medical professional, but I can provide some general information. It's crucial to consult with a healthcare professional for personalized advice.
Participation in sports with one kidney may vary depending on individual health conditions and the specific sport. Generally, sports that involve a higher risk of abdominal trauma or injury may be considered less safe for individuals with a single kidney.
Considering this, contact sports like field hockey may pose a higher risk due to the potential for injury. However, the safety of participation can also depend on various factors such as the level of competition, protective gear used, and the specific circumstances of the individual.
Again, it is crucial for someone with a single kidney or any medical condition to consult with a healthcare professional for personalized advice based on their specific health status and the nature of the sport they wish to participate in.
