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.
Single-sided, single-layer DVDs can store about seven times more data than CDs. A large part of this increase comes from the pits and tracks being smaller on DVDs. 1  CD = 1600 nanometers. 2  DVD = 740 nanometers. 3  CD = 830 nanometers. 4  DVD = 400 nanometers. 5  CD = 830 nanometers.
