Designing sport & exercise science experiments ๐
-
The Big Idea: Experiments in sports and exercise science often look for cause and effect, e.g., "Does drinking a magic potion (let's call it caffeine ๐) make you sprint faster in a 100m race?"
-
Experimental Design Flaws:
- Imagine you're training for that big race. Every time you practice, you get better, right? That's the "learning or habituation effect".
- Question: If we see an improvement after taking caffeine, how do we know it's because of the caffeine and not just because the runner is getting better with practice?
Enter the superhero control group ๐
- Control Group: This is like having a twin who doesn’t take the magic potion. You compare their times to yours to see the real difference.
- BUT! What if our "caffeine crew" expects to run faster because they took the caffeine and the control group expects no change since they got nada? This expectation might itself affect the results. Mind tricks everywhere!
Magic trick the placebo ๐ญ
- It's like getting a candy that you think might be the magic potion but it's really just... candy. Tastes the same, but no magical sprinting powers.
- Blinding the Participants: Participants don’t know if they got the real deal or the candy. If both groups think they might've gotten the magic potion, their expectations are the same.
- Double-Blind Experiment: It's like a magic show where neither the magician (experimenter) nor the audience (participants) knows the trick. This way, the magician can’t accidentally give any hints.
