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.
The typical levels of creatinine in a healthy adult depends on several factors, including age, gender and activity levels. Traditionally, the average level of creatinine in a man is about 1 to 2 grams. For women, the average levels of creatinine are only slightly lower, ranging from about half a gram to one gram.es, creatine levels can fluctuate. The levels of creatine in your body will change based on many factors, including diet, exercise, medications and overall stress levels. Creatine is a molecule found within the body, and is developed simply by the food that you consume. This food turns into energy as it metabolizes.
