Using the 2023 [WADA Anti‑Doping Rule Violations (ADRV) Report](
https://www.wada-ama.org/en/data-research/anti-doping-statistics?utm_source=chatgpt.com), I calculated the rate of Adverse Analytical Findings (AAFs) as:
> **AAF rate = total AAFs ÷ total samples tested**
To avoid tiny-sample distortions (e.g. sports with only a few dozen tests), I filtered to sports with at least ~400 samples in 2023.
## Highest AAF rates by sport (2023)
| Rank | Sport | Samples | AAFs | AAF rate |
| ---- | ------------------------- | ------: | ---: | ---------: |
| 1 | Bodybuilding | 865 | 101 | **11.68%** |
| 2 | Fitness | 516 | 50 | **9.69%** |
| 3 | Mixed Martial Arts | 461 | 34 | **7.38%** |
| 4 | Para-Powerlifting | 1,410 | 23 | **1.63%** |
| 5 | Boxing | 5,223 | 66 | **1.26%** |
| 6 | Judo | 4,812 | 40 | **0.83%** |
| 7 | Athletics (track & field) | 41,477 | 333 | **0.80%** |
| 8 | Basketball | 6,524 | 51 | **0.78%** |
| 9 | Cycling | 24,781 | 179 | **0.72%** |
| 10 | Rugby Union | 10,386 | 58 | **0.56%** |
These figures come directly from the sport-by-sport AAF tables in the 2023 report.
## Overall average across all sports
WADA reported:
* **271,775 total samples**
* **2,301 AAFs**
So the overall global AAF rate in 2023 was:
[
2301 / 271775 \approx 0.8467%
]
So the overall average was approximately:
> **0.85% of all samples tested produced an AAF**
A notable takeaway is that athletics had a very large absolute number of positives (333 AAFs), but because it is tested so heavily, its rate was lower than bodybuilding, combat sports, and several strength-focused sports.
