Aim: The purpose of this research is to examine the impact of regular physical activity on the amino acid profile of individuals living in the provinces affected by dust particles in Iran. Methods: There were a total of 50 inactive healthy men, with an average age of 31.64±1.5 years and a body mass index of 26.33±5.6, from three provinces in Iran: Khuzestan (n=15), Ilam (n=15), and Kermanshah (n=20) randomly assigned to two control and regular physical activity groups. Prior to the study, 48 hours prior to the occurrence of dust particles, and after the study amino acids, fat percentage, maximum oxygen consumption, were measured. Results: It was found that time (pre-test - May 12, 2023) had a significant effect on amino acids, maximum oxygen consumption, body fat percentage in the training group (p<0.05). In the control group, there was no significant difference in the amino acid, maximum oxygen consumption, body fat percentage, (p>0.05). In terms of body fat percentage, there was a significant difference between the control and exercise groups (p=0.01), as well as maximum oxygen consumption (p=0.01). Conclusion: This study has demonstrated that regular exercise training reduce dust particle damage in those exposed to dust particles.
