How do you calculate compression of metals if they cooled under -73 degree temperature?
Either the question is misworded, or more information is needed. Compression implies load; in order for a peice of metal to be loaded by a temperature change, it would need to be rigidly restrained by something with a different coefficient of thermal expansion. If you mean what is the dimensional change, that is answerable. It is as follows: (original size) X (coefficient of thermal expansion) X (temperature difference) = (change in length) You need to look up the coefficient of thermal expansion, and make sure you get the units right: /°C or /°F

What is the daily protein intake when weight training?
Assuming that you are doing an intense, whole-body strength training session twice a week, it is a good idea to increase your intake of proteins above normal. You should also be eating a protein-rich meal every three or four waking hours. This means at least five meals of at least 15 grams of proteins each time for adult females and at least 20 grams of proteins each time for adult males. Your weight is also a factor, with many sources citing about 1 gram of protein per pound of body weight. It is best to get your protein from natural sources such as (unless you are vegetarian) grass-fed organic beef or sockeye (wild) salmon, but protein shakes with whey protein are fine.
In order not to get fat eating so frequently, decrease your daily carbohydrate intake. Avoid all processed (refined) carbohydrates (see the list further down this page) and keep your total carbohydrate intake below 80 grams. This will switch your body from burning sugar (all carbohydrates when digested become sugar) to burning fat, which will improve your appearance, how you feel, and make you healthier. For more information about how to build muscle or alternatively how to build muscle and burn fat, see the page links, further down this page, listed under Related Questions.
Do lifting heavy weights stop you from growing?
Yes, because when you squat alot your bones get compact and you will eventually stop growing
If you are still growing now, lifting heavy weights won't actually stop you from growing so much as cause joint, muscular, skeletal, and general problems with your physical development.
Young people still developing shouldn't attempt weights until it's certain they've stopped growing. The complications from weighlifting at too early an age can be absolutely miserable: better to be taller than you might like than in pain and with restricted movement.
If you feel you are too tall, try concentrating on being as healthy as possible so that you look really good, even if you'd like to be shorter. As you mature you'll quite likely discover all kinds of advantages to being tall.
Here are opinions:
It's best to run and lift weights at opposite ends of the day. For example, run in the morning and lift weights in the evening. Do whatever you are comfortable with. If you want to develop muscle then train with weights when you have the most energy.
Always do weight training or anaerobic exercises first. By running or working out aerobically first your muscles will not be at maximum capacity when you try to lift your weights, which is very important if you want to get maximum results ASAP.
According to University Profs from University of Alberta, an individual should develop their strength and power base before working on their cardiovascular endurance. * For in-depth information about how to combine cardio exercise and weight training, see the page link, further down this page, listed under "Related Questions."
Inside your muscles you have stored sugars wich are called glycogen, when you weight train or run for example you use this glycogen store as energy. now.... when you run for example it takes about 20 minutes for the human body to deplete these stores of glycogen as energy before it has to then find new sources of energy within the body. more often then not, your body will then tap into your "stored" energy supplies wich is..... you guessed it, FAT, FAT is excess energy wich has been stored around your body for later use, now back to the point, if your weight training and running for weight loss and muscle gain, using for example what ive said above, it would be far more beneficial to weight train before doing a cardio vascular workout because, you are using your bodys glycogen supply BEFORE you start running, this means it will take less time for your body to then tap into other energy systems and deplete them. (body fat for example) and then eventually aiding you in reaching your final goal. do bear in mind however it can also make you far more tired then doing it the other way around for the pure fact that you are depleting such an important energy system before the end of your workout, (ever wonder why your body shakes and feels weak after a hard weight training session? that's because your muscles are runnning low on glycogen "sugar" so that's why glucose power drinks help to replenish depleted supplies!)
A teacher once said in nursing school that if you use hormones or other muscles building "pill" techniques then muscle will not be lost if you stop taking the "pill" but it will be harder for you to work out and continue building muscle unless you work twice as hard at it because the hormone makes it easier for you to gain muscle.
maybe alot of the 10 pounds is probably water weight

How old should you be before you lift weights?
Experts disagree. It is probably best to wait until you are at least 16. Before then, concentrate on all-around coordination, flexibility, and growth by participating in multiple standard sports. Once you begin, be sure to learn and use perfect exercise technique or you are very likely to injure yourself and set back your progress.
Can you lose weight in one workout?
Kinda-sorta, but not really.
From a single workout, the only weight loss you are likely to see is from water lost through sweating and panting. And that weight you'll put right back on as soon as you have had something to drink.
Run every day. Monday, run 1/2 mile, jog 1/2 mile. Tuesday, run 1 mile, jog 1 mile, and so on.
Is it okay to take weight loss pills?
Only if they are prescribed by your physician. There is no quick fix. Diet pills and starvation diets don't work well to promote lasting weight loss. The only way to lose body fat and keep it off is to teach yourself how to eat and exercise well and do it. Don't do anything you wouldn't do for the rest of your life. Since you are presumably not foolish enough to take weight loss pills for the rest of your life, don't taken them at all.

First, you must consult your physician regarding that matter because it's not easy to give an advice when it comes to that kind of thing. It's related to a medical problem rather.

What is considered strong for a 15 year old girl?
My brother always told me to be strong you have to bench your weight and squat 2 times it. I weigh 135 and bench that, and the most I've squated 240 but i have bad knees. At a powerlifting meet I had 264 but I move my finger. I also got stares because a was a freashman. What strong depends on you and how long you've be doing it.
