The effects of omega-3 supplement on pulmonary function of ranger troop volunteers participated in classic training

The purpose of this study was to examine the effects of omega-3 supplement on pulmonary function of ranger troop volunteers who were taking part in classic training. For this purpose 41 healthy ranger troop volunteers with age mean of 18. 6±0. 9 years، height mean of 169. 9±9. 2 cm، weight mean of 63. 5±12. 7 kg and BMI mean of 23. 7±4. 7 kg/m2 participated in this study. Subjects randomly divided into supplement and placebo groups. The both groups performed classic training 4-5 sessions per week for 8 weeks. Then each group was asked to consume 1000 mg/day omega-3 (for supplement group) or placebo (for placebo group) for 8 weeks. The pulmonary tests were measured before and after the study period. Results indicated that combination of exercise and omega-3 consumption، significantly up-regulated pulmonary variables. Our study showed that consuming 1000 mg/d omega-3 in the courses of classic training induces positive changes in the lung volumes and capacities of ranger troop volunteers.
