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.
CD Audio (.cda) tracks are audio files that can be stored on CD media. The .cda files are representations of CD audio tracks and do not contain the actual pulse code modulation (PCM) information. 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).
