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.
Difference Between DVD-R and CD-R. DVD-R and CD-R are two devices used to store data. While DVD-R stands for Digital Versatile Discs-Recordable, CD-R stands for Compact Disc-Recordable. The basic difference between the two lies in the amount of data they can store. While a CD is able to store only 700 MB data, a DVD-R can hold up to 4.7 GB of data.
