When your muscles burn, it means you have gone from aerobic respiration to anaerobic respiration. Aerobic respiration, or cellular respiration, uses oxygen to produce the ATP your muscles need to function. When you run long enough or fast enough, however, your muscles run out of oxygen and must turn to anaerobic respiration, which also produces ATP but has lactic acid as a waste product. It is the lactic acid that makes your muscles burn and makes them sore afterwards and the next day.
You are using your legs when in a race, so those muscles are susceptible to "burning," or losing muscle mass.
Lactic acid builds up because of lactic acid fermentation.
Mostly your Quad muscles
Running raises our metabolic rate, so we burn calories even while at rest. Running helps to burn calories while watching TV, while sleeping, even while taking a shower.
No it doesnt you need to move your legs so you can use all of your leg muscles which causes you to burn more calories otherwise you are only using your calf muscles
Your triceps and biceps. Your calfs and thigh muscles. there, i think, are muscles in your tourso that are active. then your heart and lungs.
yep like if you running whilst smoking you burn fat
Running does affect weight loss pretty significantly. Running is a pretty good form of cardiovascular exercise that can help you burn your excess fat and build your muscles.
Quite a few muscles go to work while running. While there are the obvious muscles (Such as calf, thigh, hip, and hamstrings) other muscles are subtly at work also. The abdominal muscles are slightly worked, along with the arms and back muscles. The arms are constantly swinging, going against air friction/wind during the run. Your back helps keep you in the upright position and is constantly shifting while you take each step. So pretty much your entire body goes to work while running (even your toes which push you off the ground). Hope that helped :)
Around 800.
The best way for you to burn lots of calories while running is to run up hills or at an incline. If that is not an option you can also run up and down stairs those provides a lot of burn calories.
Pain in the stomach while running is called a side stitch. This may be due to membranes and muscles rubbing against each other.
If you are swimming at a pretty decent pace you should burn more calories than running because you are using more body muscles, like your arms, legs, back muscles, and abs.
Because exercise works Ur muscles which causes the fat cells to shrink! :)
