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.
