No ... its your adrenaline
I am presuming this question is from a male, so shall answer as such. During puberty, testosterone is produced in a great amount and greatly affects the body in many ways. Testosterone greatly affects muscles, which is my men are scientifically proven to be capable of building muscle mass faster than women, who produce little testosterone, but instead, estrogen.
Testosterone has a large part to do with this
YES
There is no way to get taller faster. it's not the best way but testosterone boosts...
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
natural fibres decompose faster than man made fibres because latter is a synthetic fiber. synthetic fibre has a plastiy smell. any thing made of plastic will not degrade.
No. Supplements are for people who want to build muscles faster.
The faster your blood circulates, the faster blood can get to your muscles, giving you more energy in your muscles to use those muscles. Muscle cells need oxygen to work just like any other cell.
faster, the testosterone increases the muscle power, allowing it to charge in small rushes of speed
Because when your muscles are working they need more oxygen and nutrients, which they get from the blood. And for the blood to be able to carry more nutrients to the muscles the heart has to pump faster.
