Abstract

Introduction: Various environmental and genetic factors, such as inflammation caused by intense sports activity, affect the immune system response of athletes. One method of preventing the inflammatory process and helping the immune system is probably to take anti-inflammatory drugs like cinnamon. The purpose of this study was to investigate the effect of one-week consumption of cinnamon supplement on the immune response to one session of exhaustive exercise in active boys.

.Methods: This study was a kind of quasi-experimental, and single- blind. Study population was male collegiate sport man at Shiraz University. 12 healthy students (age: 22±1.93 year, height: 172.56±6.56 cm, weight: 66.56±11.54) participated in the study voluntarily and by a crossover method. Participants performed Bruce exhaustive exercise test in two situations of consuming cinnamon and placebo. Daily 500 mg cinnamon or similarly placebo during one weeks before exercise sessions were consumed by participants in single-blinded method. Blood samples were taken before and 15 minutes following exercise. T dependent test was used for data analysis and significant level was set at p<0.05.

Results: cinnamon supplementation did not affect significantly monocyte before and after exercise (P=0/154), but caused significant reduction of neutrophils and neutrophil to lymphocyte ratio and increase lymphocytes in rest(before exercise status). Cinnemon supplementation reduced significantly exercise induced changes in neutrophils (decrease), lymphocyte(increase), neutrophil/lymphocyte(decrease) (p values, respectively p=0.015, p=0.012 and p=0.02).
