An increase in insulating atmospheric gasses (e.g. carbon dioxide)
The main driver of a climate zone is the amount and directness of sunlight that reaches the Earth's surface. In the tropical regions, there is a fairly constant amount of sunlight throughout the year. The maximum sun angle is also higher above the horizon.
There are two ways to continuously keep providing energy to the muscles in the body. The body uses the aerobic pathway where the glucose is used to make the ATP to provide energy to the muscle cells. If the store of ATP gets reduced, the body triggers homoeostasis mechanism involving the anaerobic pathway. In this pathway, glucose is converted into lactate in the muscles tissues. This lactate is used to make ATP that is used by the muscle cells. This way the body ensures that the supply of energy is maintained throughout the run.
Answer:
pH - Each enzyme has an optimal pH at which it works best, if the pH is too acidic or basic, the enzyme will start to denature.
Temperature - Each enzyme has an optimal temperature at which it works best as well. If it is too hot, the enzyme will start to denature and if it is too cold, there will be fewer collisions between enzymes and substrates.
