Compression therapy is widely used among athletes in sports worldwide for its multitude of benefits to the human body. Compression improves performance by promoting blood flow, reducing muscle vibrations, and decreasing fatigue while increasing structural support and combating the annoying effects of DOMS (delayed onset muscle soreness). In addition to performance benefits, compression is beneficial for healing damaged or torn muscles after sudden injuries.
