- Registration Number
- NCT03758599
- Lead Sponsor
- Universitaet Innsbruck
- Brief Summary
Aim: Aerobic and resistance exercise showed anxiolytic effects in clinical populations. Climbing could further enhance self-efficacy. Aim of the study is to examine whether climbing exercise and aerobic exercise, compared to social contact control, reduces symptoms of disease in out-patients with anxiety disorder (AD) and post-traumatic stress disorder (PTSD). Further analyses are aiming to reveal differences between climbing - and aerobic exercise.
Design: Randomized controlled clinical trial Participants: Thirty out-patients diagnosed with International Classification of Disease-Version 10 (ICD-10) (F40, F41, F43.1) for AD or PTSD.
Intervention: Out-patients will be assigned randomly to a climbing exercise group (a), aerobic exercise group (Nordic walking) (b) or social contact control group (c).
Measurements: Primary outcome is symptom severity in AD or Post Traumatic Stress Disorders. Further secondary outcomes are evaluated by psychological questionnaires assessing depression, worry symptoms, quality of life, self-efficacy and affective responses. Metabolites of neurotransmitters, immune-activation markers and anthropometric data will be additionally provided as secondary physiological outcomes.
Duration: Intervention duration is four weeks with 2 x 75 min for every group (climbing exercise, aerobic exercise, social contact control). Measurement points are set at the beginning (t1), at the end of the intervention (t2) and 3 (t3) and 6 (t4) months follow-up.
- Detailed Description
The proposed research project is designed as a randomized controlled clinical trial with three arms. The efficacy of a climbing exercise program, an aerobic exercise program and a social contact control group on primary and secondary study outcome will be investigated (see Figure 1). Patients will be first screened by the outpatient-unit of the Department of Psychosomatics at the Medical University of Innsbruck or remitted through the treating staff network community. When assessed as eligible for the study, a group of up to ten out-patients will be randomly selected and invited to an informative meeting. Patients receive study information and time tables for their group attendances. The intervention will start within the following week and will end four weeks after beginning. Follow-up assessments will take place three and six months after intervention.
In addition to the AD/PTSD symptom screening, secondary study outcomes will be assessed:
* at study inclusion (t1)
* at the end of the intervention (t2)
* three months after the intervention (t3)
* six months after the intervention (t4)

Group Intervention Description Social Contact Control Group Social Contact Patients allocated to the social contact control group will receive the same amount of social interaction as the exercise groups. A physiotherapist or sport scientist will be present while participants watch movies with relevant content to disease followed by interactive group discussions. This group is required to control for the impact of social contact/support on AD/PTSD and secondary outcomes. Aerobic Exercise Group Nordic Walking As the climbing exercise group, the aerobic exercise group will start with a ten minutes body-centered, mind-setting warm-up, followed by 60 minutes of Nordic walking and five minutes cool down. A physiotherapist or sport scientist will instruct and guide the group. Nordic walking will be performed at a moderate pace at varying paths. Climbing Exercise Group Climbing At the beginning of each session, a standardized body-centered, mind-setting warmup of ten minutes will take place. The general warm-up will be followed by climbing specific warm-up, which will consist of bouldering (20-30 minutes). Afterwards the rope climbing session will start. Climbing sessions also contain several sport-specific skill-development training sessions to familiarize the participants with gear and rope management, to acquire footwork and route finding, and to locate good belay spots and resting positions while climbing. At the end of the climbing session a short cool-down of five minutes will be executed.
