Conventional wisdom is to put ice on a muscle or joint during the first 48 hours following an injury. Ice decreases inflammation, which should promote healing. A Japanese study found the opposite: heat promoted healing by stimulating satellite cell formation and protein synthesis in the injured muscle. Following injury, the muscles form satellite cells which fuse to the injured part of the cell and add new contractile tissue. The scientists caused muscle damage by injecting a chemical poison. They concluded that heating promotes recovery of injured muscle. We need more studies before we can recommend such a dramatic departure from current practice.
