Athletes use a combination of strength training, diet, and nutritional supplementation to induce muscle hypertrophy. Muscle hypertrophy involves an increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril size.
CD media. Compact discs hold 700MB of data (equivalent to 80 minutes of audio, hundreds of high-quality digital images, and small video files). Unlike DVDs, CDs are not yet available in double-sided or dual-layer formats.
The limitations are there is less space to store a video on a cd vs a dvd. A cd can hold about 800 meg max, a dvd either 4.7 or 8.5 gig. Yeah. Even though they are the same size, a dvd holds 6 or 12 times more data. This means that you are constrained as to how much and how good the quality of the video will be. A 90 minute movie can be made to fit on a cd but quality might suffer.
