The response of cytokines and stress hormones to one session of intensive
aerobic exercise in cold environment in active women
Abstract
There are many hormones interaction between immune and nervous systems which are common in
some messenger molecules as cytokines and the purpose of this article is to study the effect of one
session 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 control
groups. The experimental group had pedaled the bicycle ergometer at VO2max 75% for 60 minutes
and the control group had no activity during the test. The environmental temperature and humidity
were maintained the 4◦C level and 40% respectively fixed during the test. Blood samples for
measuring the levels of IL-10, TNFα, CRP, cortisol and epinephrine were taken in pre, immediate
and 2 hours after termination of the activity by participants. Findings: There was no any significant
difference 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 significant
difference 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 imunohormonal
response to the exercise in women athletes.
