The response of cytokines and stress hormones to one session of intensive aerobic exercise in cold environment in active women

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.

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 41C level and 40% respectively fixed during the test. Blood samples for measuring the levels of IL-10, TNF!, CRP, cortisol and epinephrine were taken in pre, immediate and 2 hours after termination of the activity by participants.

There was no any significant difference between control and experimental groups in concentration of IL-10, TNF!, 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).

one session of intensive activity in cold environment can not affect the imunohormonal response to the exercise in women athletes.
