Effect of inspiratory muscle training with royal jelly supplement on iron metabolism in cigarette addicts

Abstract

Objective: The strength or weakness of the respiratorymuscles comparedwith other skeletal muscles owing to their more specialized structures is considered as an indicatororcause of a disease. This study aimed to investigate the effects of inspiratory muscle training with royal jelly (RJ) supplement on ironmetabolism in cigarette addicts. Materials and Methods: A total of 40 male volunteers participated in the study who were divided into 4 groups before the study as follows: smoker control group (n=10), inspiratory muscle training (IMT) group (n=10), RJgroup (n=10), and RJ+IMT (n=10) group. Blood samples were taken from all the participants for analysis of iron, ironbinding, and total iron binding capacity. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) measurements for the groups to perform trainingwere carried out with 40% of their MIP values. The training sessions were carried out at thesame time every day for 4 weeks (5 days per week). Results: The Statistical Package for Social Sciences version 22.0 program was used for statistical analyses. The results of the analysis found that the iron, ironbinding, and total ironbindingcapacities were in favor of post-tests in theRJ supplement IMT, and RJ+IMT groupscompared with those in the control group (p<0.05). Therewas a statistically significant difference between the RJ supplement, IMT, and RJ+IMT groups compared with the controlgroup (p<0.05). Conclusion: Therefore, it could be concluded that the IMT and RJ supplements positively affected these parameters by altering the iron metabolism of the cigarette addicts.
