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.

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

Participants will perform executive function test
