Abstract

The response of cytokines and stress hormones to one session of intensiveaerobic exercise in cold environment in active womenAbstractThere are many hormones interaction between immune and nervous systems which are common insome messenger molecules as cytokines and the purpose of this article is to study the effect of onesession of intensive aerobic exercise in cold environment on active women. Materials and method:sixteen physical education students with average age of 20.25 ± 0.93 years, Vo2max 42.14 ±9.81ml.kg.min and BMI 22.11± 2.66 kg/m² divided randomly in tow experimental and controlgroups. The experimental group had pedaled the bicycle ergometer at VO2max 75% for 60 minutesand the control group had no activity during the test. The environmental temperature and humiditywere maintained the 4◦C level and 40% respectively fixed during the test. Blood samples formeasuring the levels of IL-10, TNFα, CRP, cortisol and epinephrine were taken in pre, immediateand 2 hours after termination of the activity by participants. Findings: There was no any significantdifference between control and experimental groups in concentration of IL-10, TNFα ,CRP,epinephrine when they were doing intensive activity in cold weather. There was only significantdifference between groups on concentration of cortisol immedintely after activity (p≤0.05).Conclusion: one session of intensive activity in cold environment can not affect the imunohormonalresponse to the exercise in women athletes.
