Effect of intraperitoneal administration of calcium ions on body temperature in rats during exercise in hyperthermia.

Animals with body temperature reduced by intraperitoneal injection of calcium ions were subjected to intensive exercise at raised ambient temperature. A significant difference was observed between the experimental and the control group in body temperature rise (p less than 0.001). The rats of temperature rise was significantly lower in the experimental group. The adaptation ability to hyperthermia was demonstrated to be greater in the animals receiving calcium.
