Isotonic drinks and long-distance runners
The results show that the runners in the first group wearing the red T-shirts were able to improve their time in the second race after drinking the isotonic drink (i.e.Gatorade). The runners in the 2nd group did not show much improvement in their average running time.
|Group||Precondition||Time to complete 5 km run (minutes)||% change|

|1||Red – Isotonic drink||22.15||19.27||-13.00% (faster)|
|2||Blue – water||22.65||22.45||-0.88% (faster)|
