Does your top speed improves along with your endurance?

No, your body uses a different energy system for top speed running than for distance running and improving one has no effect on the other.

There is only 1 energy system.

Top speed training can slightly improve endurance.

Endurance training does not improve top speed.

Endurance training can improve finishing times in many races, but dont confuse that with top speed abilities, which is the highest possible velocity you can achieve.

ATP

But it's produced in 5 different ways. 2 of them are aerobic, and 3 are anaerobic.

Name those 5 systems?

No

It might improve you finishing speed but not pure speed over 60m

If you're a 12 minute/mile recreational runner, then your top speed will improve as your endurance improves, especially if you do a weekly interval workout. Your body is adapting to actually running as you get below... say... 9 minute/mile pace.

For faster runners, running faster requires training the central nervous system, fast-twitch muscles, running form, and even breathing. I used to be shocked when I'd return to high-speed training after a break. I'd feel like my legs were just flailing around until they got acclimated to the faster pace.
