Myth: Genetic testing is a precise science that tells you disease risk, exercise optimization, and lineage Fact: Most genetic test results are very sketchy, built on vague regression models and the test results of white people

Also worth noting that these differences weren't in actual scores, they were in PERCENTAGE CHANGE. So genetic matching improved athletes' scores by about 5% more over 8 weeks of training

So say you have two groups. Both start with a score of 10. What this would mean is that, after 8 weeks of this special training, one group scores 11 and the other one scores 10.95 Magic

But even better, the groups WEREN'T RANDOM. This is actually brilliant, because it shows how finicky trials can be The study groups were randomized to two INTERVENTIONS - either high or low intensity training

But the analysis variable is genetic testing. So actually what the researchers did was take their nice, randomized groups, and destroy them This is never mentioned in the study, but is a significant limitation

Anyway, these are two of the BETTER genetic testing studies because at least they trialled some kind of intervention Mostly you just see a big predictive algorithm built on white guys and some fairy fluff

It's amazing how much of genetic testing, outside of specific diseases and direct ancestry (parents, cousins etc) is just "hey look these genes correlate with that expression LET'S ASSUME CAUSATION THAT'S A GREAT IDEA"
