Abstract
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.
Highlights
Today, addiction is known as a global problem facing all countries [1]
Considering that no research has so far investigated the effect of resistance training on neurotransmitters and the pulmonary function of addicted persons, the aim of this study was to examine the effect of resistance training on some neurotransmitters and the pulmonary function of men after quitting the addiction
The comparison of pre- and post-test changes between experimental and control groups showed that the dopamine levels (P = 0.001), serotonin (P = 0.001), maximal voluntary ventilation (P = 0.000), and forced vital capacity (P = 0.002) were significantly different after 8 resistance training weeks compared to the control group (Table 1)
Summary
Addiction is known as a global problem facing all countries [1]. Substance use disorder and drug dependence have become one of the major problems in the world and, after the nuclear crisis, population explosion, and environmental pollution, have ranked the fourth global human crisis [2]. 70% of drug users, in the first year after quitting, return to using again [6] This is a very high relapse rate. 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. 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). 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 it can be used as a non-pharmacological approach to help these people to quit the addiction.
