Your stride tends to get longer as you run faster, but, no, your legs do not.
your breath 🤣😂
your breath
Yes, it tends to run faster and has more features
when running move arms quicker to run a bit faster, start it slow, by taking easy breaths the faster you move the quicker you will breath
a muscular man would run faster than a thin man because he physically built
Because you are using up Oxygen in your blood faster then you can replace it. Breathing gets the oxygen in, Work uses it up. If you use it up faster than you get it in you "run our of breath". (your body is telling you to "stop for a bit, and let it catch up") There are medical problems that can cause "shortness of breath" so if unsure go visit your doctor.
In a perfect world, yes. Their stride (or distance between legs when they're moving them) tends to be longer. However, it takes more energy to move the extra mass and most of the time it evens out.
no
The waves and water resist your motion.
No shoe is designed to help a person run faster. They will provide you with the comfort and fit you need to be able to run great distances but speed is ultimately up to you.
so that the person who is listening to you can understand you and so you dont run out of breath
