Worked Solution & Example Answer:The normal haematocrit for human males is 47(±5)% - AQA - A-Level Biology - Question 7 - 2020 - Paper 1
Step 1
1. Professional Integrity and Fairness
Answer
Allowing professional male cyclists to use EPO until their haematocrit reaches 50% undermines the integrity of the sport. This practice would create an uneven playing field, where performance becomes reliant on artificial enhancements rather than natural talent and training.
Step 2
2. Health Risks and Ethical Concerns
Answer
Using EPO can pose significant health risks, including increased blood viscosity, which can lead to cardiovascular issues. Furthermore, promoting the use of performance-enhancing drugs raises ethical concerns regarding athlete welfare and the true nature of competition.
