The Effect of Resistance Training on Some Neurotransmitters and Men’s Pulmonary Function After Leaving Addiction

Background: Addiction is now recognized as a global problem facing all countries. Reducing neurotransmitters in addicts is an important barrier to drug addiction. The purpose of this study was to investigate the effect of resistance training on some neurotransmitters and the pulmonary function of men after quitting the addiction. Materials and Methods: In this regard, 20 subjects were selected as the statistical samples of this research and were randomly divided into control (10 people) and resistance training (10 people) groups. The experimental group performed 3 sessions of circular resistance training for 8 weeks and weekly with 50%-65% intensity in one maximal repeat. Then, the subjects’ blood sample (4 cc blood) was taken in order to study the variables of the research 48 hours before and after the implementation of the protocol. Next, all biochemical variables of dopamine and serotonin were measured by enzyme-linked-immunosorbent assay. Finally, all statistical calculations were performed using SPSS software, version 16 and P≤0.05 was considered as a significant level. Results: The results of the study showed that 8 weeks of resistance training significantly increased dopamine levels (P=0.0001), serotonin (P=0.0001), maximum ventilation volume (P=0.0001), and vital capacity (P=0.0002). Eventually, the results indicated that 8 weeks of resistance training did not significantly change the forced expiratory volume in seconds (P=0.628). Conclusion: According to the results of the study, it seems that 8 weeks of resistance training can increase neurotransmitters and pulmonary function in men who are addicted to drugs, and therefore, it can be used as a non-pharmacological approach to help these people to quit the addiction.

Scaling Behavior of Maximal Repeat Distributions in Genomic Sequences

The maximal repeat distribution analysis is redone by plotting the relative frequency of maximal repeat patterns against the rank of the appearance. In almost all of the cases, the rank plots give a better coefficient of determination values than the authors’ previous work, i.e. frequency plot was used. A randomized version is repeated for the maximal repeat study; it is found that rank plot regression analysis did not support scaling behavior; hence, the validity of the findings is not due to an artifact.
