“…Swimming with a load is often used as a model of stress-inducing physical exercises. Swimming for 3 h was found to induce adaptive changes associated with genome activation in the cerebral cortex, which is considered to provide a basis for enhancement of the CNS functional potential [3,6]. Activation of the kallikrein-kinin system (KKS) observed within the same period after exercise [2] contributes to the stress-limiting mechanisms by stimulating microcirculation and prostaglandin release, which diminishes the effects of catecholamines [5,14,17].…”

In rats, adaptation to strenuous exercise was accompanied by phasic changes in the activities of the kallikrein-kinin system, elastase-like proteinases, and proteinase inhibitors, and total antioxidant activity in the serum, myocardium, liver, and cerebral cortex. After 30-rain physical exercises, activity of the kallikrein-kinin system decreased in the serum and increased in tissue with parallel activation of elastase-like proteinases in the myocardium and cerebral cortex. After 3-h exercises the activity of the kallikrein-kinin system showed some indications of exhaustion, especially in the myocardium and cerebral cortex. Activities of elastase-like proteinases tended to normal due to activation of txl-proteinase inhibitor and normalization of total antioxidant activity.
