i get somewhat of a burning sensation in my quad when i run?

Question

it's not bad enough to make me have to stop running, but it definitely makes it difficult to keep going, especially when i'm not feeling entirely motivated to begin with. i'm only 13, so im still growing, could this be a cause of it? i've been running since i was 5 years old, so my legs are definitely used to the wear and tear... that said i definitely do not run too much and make sure i take 2 weeks of rest after every season, so it's not a result of overtraining. any ideas of the cause and how i can help this?

it gets worse when im going up hills, no matter how slight the incline

Answer 1

Even though you have been running since 5 did you just start back?You don't have the muscle endurance yet and yes your muscles are growing along with your body so even the same exercise that you have been doing for years will feel different from one year to the next in this stage. When you run your muscles are continually break down and there's more to break down now. When you don't feel it or ignore it is when you are overtraining and doing damage. Keep working out and I promise you it will get better but never really stop.

Answer 2

Lactic acid builds up in your muscles and bloodstream at all times when you are running. However, it really only becomes an issue when you are running at an effort level where your body's ability to transport oxygen can not keep up with the demand for oxygen from your muscles. At this point, your muscles have to switch over to other methods of energy production. The byproduct of what becomes the primary energy production source is lactic acid. Once it is accumulating faster than it can be cleared, the pH levels of your muscles and bloodstream lower and your body basically becomes acidic. This can't last long, which is why if you go too far beyond your "lactate threshold" you can't hold the pace for very long.

The cooling down thing is actually not totally true. Once you stop exercising at the intensity above your "lactate threshold", the lactic acid in your body will very quickly be broken down into a non-acidic energy source and stored for later energy consumption or more immediately used to produce energy. It used to be believed that cooling down was a mechanism for clearing lactic acid but is now understood that lactic acid will clear from the muscles and bloodstream approximately as rapidly whether you cool down or not. There are actually other reasons for cooling down.

Answer 3

yea, there's a chance it could be growing pains, but theres a larger chance it's from lactic acid, which is responsible for the burning sensation in your legs when working out-
caused by lack of Oxgyen-
just work on more constant, even breaths, and always make sure to stretch before yea?
it can only get better,
good luck

YOu are using your toes too much. The correct way to allign your body weight so not to damage the knees or front of the leg is to make sure the heel touches first always, even up hills and stairs. You will build up lactic acid too fast , or strain the quads using too much toe first action.
It also gives you more stamina because you are not burning up the front of yuor legs that are much smaller muscles.

Answer 5

This problem might be because you have weak quadricep muscles. When I run the 400m, at the end of the race my quadriceps are burning but you still have to fight to the finish line.

Try some exercises such as wall-sits, lunges, and other good things.

Wall-sits are when you have your back against the wall and your thigh-legs are placed at 90 degrees. It's like imagining you're sitting on air and this will help build quadricep muscle.
