High aerobic intensity training and psychological states in patients with depression or schizophrenia

Aim: To explore changes in psychological states in response to a bout of high aerobic intensity training (HIT) in patients with depression or schizophrenia compared to healthy individuals. Methods: After familiarization training of HIT, 20 patients with schizophrenia, 13 patients with depression, and 20 healthy individuals performed a no-training day followed by a training day. HIT was 4 x 4 minute intervals at 85-95% of peak heart rate, intermitted by 3 minutes active rest periods at 70% of peak heart rate. Self-evaluation questionnaires of positive affect, negative affect, state anxiety, well-being, distress and fatigue were completed before training, 15 minutes after and 3 hours after training. The two latter measures were also completed the no-training day.Results: All three groups improved in positive affect and well-being 15 minutes after HIT (p0.05).Conclusion: HIT used as an acute intervention improved positive affect and well-being and reduced distress and state anxiety in patients with depression and schizophrenia.ClinicalTrials.gov identifier: NCT01310998
