Integrated Exercise Program in Opioid Agonist Therapy Clinics

The intervention is a supervised group-based exercise intervention for 16 weeks, including two outdoor sessions per week. The workout consists of two parts, endurance and a strength training segment. Every workout follows the same structure and lasts approximately 45 minutes. The exercise starts with roughly 15 minutes of endurance warm-up. After the warm-up follows the interval with eight repetitions of 30 seconds uphill, and the participants can freely choose between walking or running. The desired intensity of the intervals is \>13 on Borg-score 20. The session will end with four specific exercises focusing on strength training of large muscle groups, including mm. pectoralis major, rectus abdominis, quadriceps femoris, gluteus maximus and latissimus dorsi. The strength training program follows the same structure as the intervals. Clinical staff, research staff, and people with user experience will supervise the exercise sessions.
