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 .cda files are representations of CD audio tracks and do not contain the actual pulse code modulation (PCM) information. Cda files can be played only from a CD-ROM. The current standard for CD audio requires a sampling rate of 44.1 kHz and a sample size of 16 bits (2 bytes per sample).
