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.
DVD-Rs can hold up to 4.7 gigabytes while a CD-R can only hold up to 700 megabytes. However, when the DVD-R is formatted, it can only hold 4 gigabytes. CD-Rs can hold 74 minutes or up to 99 minutes of music. Also, when it comes to definition, DVDs are more advanced in quality. The videos in the DVD are more focused on high definition compared to the CD.
