Effect of Exercise on Cognitive Function and Mental Health in Heroin Addicts

The goal of this [type of study: exercise intervention study] is to test in describe participant health conditions. The main questions it aims to answer are: [Whether physical exercise improves executive function of male heroin addicts] [Whether physical exercise improves negative thinking/affect psychological experience of male heroin addicts] Participants will be randomly selected for medium-intensity strength training (resistance exercise,n=30), 30 will be selected for 1-hour long balloon volleyball sessions (aerobic exercise) at 60-70% volume of oxygen uptake during peak exercise, weekly 5 times for 12 weeks; and 30 will be assigned to the no-exercise control group, Participants will perform Executive function tests and the Symptom Checklist-90 Revised questionnaire at pre and post intervention. Researchers will compare resistance exercise group,aerobic exercise group and no-exercise control group to see if effects of exercise on executive function and negative thinking/affect psychological experience of male heroin addicts.

Unspecified Symptoms and Signs Involving Cognitive Functions Following Unspecified Cerebrovascular Disease, Heroin Addicts, Executive Function, Negative Thinking/Affect

play balloon volleyball for Aerobic exercise and aimed at maximizing the strain on the cardiovascular system (60-70% of heart rate recovery). Aerobic exercise intervention five times a week, one hour each time，for three months.

Resistance strength training for Resistance exercise and aimed at promoting the greatest hypertrophy response(65% of 1 repetition maximum and repeated up to 15 times). Resistance exercise intervention five times a week, one hour each time,for three months.

To investigate affect/effect of dissimilar modes of exercise, Aerobic exercise versus Resistance exercise, on execution function and psychological symptoms in heroin addicts, 1 hour of characteristic exercise protocols aiming to (a) maximize the strain on the cardiovascular system with Aerobic exercise(60-70% of heart rate recovery) and (b) promote the greatest hypertrophy response with Resistance exercise(65% of 1 repetition maximum & repeated up to 15 time) were used. Both exercise programs were designed to match the male heroin addicts, with medium-intensity Strength-Trained for Resistance exercise and playing balloon volleyball for Aerobic exercise. Two exercise groups performed at 65% of their pre-determine peak oxygen uptake.

using the Symptom Checklist-90-R (SCL-90-R) questionnaire to investigate the improvement of physical exercise on psychological symptoms in heroin addicts,

Participants will be assessed the Symptom Checklist-90-R (SCL-90-R) questionnaire at pre and post exercise intervention.
