Attenuation of Sound Waves. When sound travels through a medium, its intensity diminishes with distance. In idealized materials, sound pressure (signal amplitude) is only reduced by the spreading of the wave. Natural materials, however, all produce an effect which further weakens the sound.
There is no established dose. Many different dosages of creatine supplements have been used in studies. For athletic performance, some people start with 10 grams to 30 grams of creatine a day. This is followed by a maintenance dose of 2 grams to 5 grams of creatine a day. Natural food sources of creatine include meat, poultry, and fish.
Though creatine is produced by the human body, supplementation can increase cellular creatine content, improve muscular performance, and is associated with a variety of health effects. Meat has a high creatine content, particularly steak (5g of creatine per kg of uncooked beef), chicken (3.4g/kg), and rabbit (3.4g/kg). Eggs and fish are also good sources of creatine. Still, itâs very unlikely youâre eating enough meat to not want to supplement. The recommended daily creatine dose is five grams. Thatâs about two pounds of beef, or three pounds of chicken a day. It takes a pound and a half of herring, the best fish source for creatine, to provide five grams of creatine.
