Brief Summary

In recent years adolescent substance abuse is a serious and growing problem. Substance use among adolescents means the use of alcohol, opiates, amphetamines, inhalants, cocaine, marijuana, benzodiazepines, hallucinogens, and anabolic steroids. The United Nations Office on Drugs and Crime reports that approximately 5% of the world's population used an illicit drug in 2010 and it is estimated that heroin, cocaine and other drugs are responsible for 0.1 to 0.2 million deaths per year. There is a limited number of studies in the literature that investigate the relationship between substance use disorder and respiratory functions. In Taylor et al., study reported that the proportion of cannabis-dependent study members with an FEV1/FVC ratio of, 80% was 36% compared to 20% for non-smokers. Another research of Taylor et al., in longitudinal observations over 8 years in young adults (cannabis smoking on lung function in young adults between the ages of 18 and 26) revealed a dose-dependent relationship between cumulative cannabis consumption and decline in FEV1/VC. In a monograph, stated that follow-up studies of regular cannabis-only smokers also found impaired respiratory function and pathological changes in lung tissue like those preceding the development of chronic obstructive pulmonary disease . The core anatomically described as a box, with the abdominals at the front, spinal and gluteal muscles at the back, the diaphragm on the top, and the pelvic floor and hip muscles on the bottom. Correct breathing is vital to abdominal training because respiratory muscles are directly involved during common core stability exercises. Moreover, the diaphragm, a component of core stability, plays a role in respiration and trunk stability by controlling intra-abdominal pressure . Oh et al.reported that, 30-min, 3 days a week for 8 weeks lumbar stabilization exercise had a more positive effect on pulmonary function than general physical therapy on stroke patients. Our hypothesis was that core exercises may positive effect on respiratory functions and functional capacity of substance use disorder individuals. The aim of our study is to investigate the effects of core exercises on respiratory functions and functional capacity in adolescents with substance use disorder.

Outcome Measures

Primary Outcomes (3)

  • Pulmonary Function Test

    Pulmonary functions were measured using portable spirometry (Spirobank II; Medical International Research Rome, Italy). Measurements were performed according to the criteria of the American Thoracic Society (ATS) and the European Respiratory Society (ERS) guidelines.

    6 weeks

  • Maximal Inspiratory and Expiratory Pressures

    Participants' maximal inspiratory and expiratory pressures was measured and recorded according to ATS/ERS criteria using a portable, electronic intraoral pressure gauge (Carefusion, USA) . During the test, subjects were encouraged verbally. Technically acceptable, the highest of at least three measurements that did not differ by more than 5 cm H2O was recorded for maximal inspiratory and expiratory pressures. A percentages of the predicted values of maximal inspiratory and expiratory pressures were expressed as described by Black and Hyatt.

    6 weeks

  • Functional Capacity

    Functional capacity was measured with the 6-Minute Walk Test (6MWT) according to the guideline of ERS. The 6MWT to be a reliable, reproducible, and valid functional test for assessing exercise tolerance and endurance. Subjects were instructed to walk from one end to the other of a 30 m hallway at their own pace, while attempting to cover as much ground as possible in the allotted 6 min. The test was self-paced and the subject could rest if he or she so wished.

    6 weeks

Secondary Outcomes (3)

  • Respiratory Related Symptoms

    6 weeks

  • The Modified Medical Research Council (mMRC) Dyspnoea Scale

    6 weeks

  • The Fagerstrom Test of Nicotine Dependence (FTND)

Study Arms (2)

Exercise Group

EXPERIMENTAL

In addition to the service routine rehabilitation program, in this group all participant receive as group training with instructor supervising 5-6 participants. The specific days of the week and time of day in which the participants trained remained constant throughout each training protocol. Training programs lasted 6 weeks and comprised 2 training sessions per week with a total of 12 training sessions. A 45-60 min training sessions per week with a 2 day gap between each session.

Other: Exercise group

Control Group

OTHER

In addition to the service routine rehabilitation program, participants in the Control group participated in leisure activities such as table tennis/basketball under service staff supervision for 45-60 minutes, 2 times a week, 6 weeks similar time period of Exercise group.

Other: Control group

Interventions

Exercise group mainly conducted the 5 core stabilization exercises as described by McGill. These include the curl-up, side bridge, trunk extension, double leg lifts and bird-dog exercises that support respiratory functions. In other words, every single training session consisted of frontal, dorsal, and lateral core exercise. In general, participants always exercised in group so that for integration and motivation. During training weeks 1-2, participants exercises with 3 sets per exercise and 10 s contraction time and 10 repetitions. During training weeks 3-4, contraction times and repetitions were increased to 15 s and 15 repetitions. Additionally, increasing the complexity of exercises, adding opposite limb movements and increasing the lever arm of the exercises were done.

Also known as: Core stabilization exercise
Exercise Group

In addition to the service routine rehabilitation program mentioned above, participants in the Control group participated in leisure activities such as table tennis/basketball under service staff supervision for 45-60 minutes, 2 times a week, 6 weeks similar time period of Exercise group.
