The response of cardiovascular system to cold pressor test in athletes and non-athletes
INTRODUCTION: Numerous studies have indicated that intense physical effort is one of the key factors determining individual sensitivity to pain. AIM(S): Assessment of pain threshold and pain tolerance in boxers and non-athletes evaluated with Cold Pressor Test (CPT) taking into account cardiovascular indices. METHOD(S): The study involved 261 men aged 18–28. The first group consisted of 80 athletes, after at least five years of practicing boxing. The control group consisted of 181 students of the Faculty of Physical Culture, University of Szczecin. Pain tolerance and threshold were assessed using CPT. The Cold Pressor Test is a widely used experimental pain procedure to determine a person’s pain threshold and pain tolerance, defined as the elapsed time until voluntary withdrawal of the hand. Systolic and diastolic blood pressure and pulse were measured three times: 1) prior to the test, 2) when the pain threshold was reported, 3) at the end of the test. RESULTS: CPT indicated showed that boxers were much more tolerant to pain compare to non-athletes. All three measurements (s. Methods) showed higher heart rates in the control group. Reporting pain threshold, boxers had significantly lower heart rates compared to the control group. In both groups systematic increase of the systolic and diastolic blood pressure during CPT caused by pain stimulus (cold water) was observed, Systolic blood pressure was significantly lower in the control group after the test in comparison with boxers. CONCLUSIONS: Our observations differ to some extent from the findings presented up to now and confirm the essential role of physical activity in the constant adrenergic stimulation. FINANCIAL SUPPORT: I confirm that my study was given neither external financial support nor funding by any organization.
