Effects of high intensity interval training among overweight individuals with psychotic disorders: A randomized controlled trial

One‐year aerobic interval training in outpatients with schizophrenia: A randomized controlled trial

“…This is lower compared to a previous 8 weeks study from our group, documenting 12 of 16 inpatients with schizophrenia to complete ≥80% of the AIT sessions per protocol. 18 Adherence over time in exercise studies has been proposed as a critical issue for patients with schizophrenia 20,37 ; thus, the 1-year duration in the current study may have influenced the number of per protocol sessions. Furthermore, studies conducted in outpatient groups have often reported poorer patient attrition compared to inpatient groups.…”

“…19 Importantly, the drop-out rate was low despite the training being performed at a relatively high intensity. Although the high intensity may result in more discomfort, aerobic exercise interventions incorporating higher intensities may yet yield higher adherence than moderate-and low-intensity exercise in Sessions where treadmill exercise was performed n 21 [19][20][21][22] 18 [15][16][17][18][19][20] 28 [21][22][23][24][25][26][27][28][29][30][31][32][33][34] patients with schizophrenia. 37 One explanation for this somewhat counterintuitive observation could be the effectiveness of the training and potential for improving aerobic capacity.…”

“…19 Long-term interventions improving patient retention are sought after. 20 Importantly, the majority of patients have reported that exercise supervision would likely make them exercise more. 16 Our group showed that shortterm AIT involving both specialized and municipal health services, which may be regarded as a collaborative effort to integrate training in standard outpatient treatment, was feasible.…”

High‐intensity interval training: an adjunctive treatment for schizophrenia spectrum disorders?

“…A 6‐month protocol whereby 66 people with psychosis were randomized to HIIT twice weekly or usual care observed significant improvements in global and social functioning, negative symptoms and WC following HIIT compared with usual care . Moreover, a feasibility RCT with 16 people with a psychiatric diagnosis, including those with schizophrenia, observed attendance, drop‐out and enjoyment factors following 12 weeks of HIIT thrice weekly and 12 weeks of MICT thrice weekly .…”

“…Since these encouraging findings, three RCTs have investigated HIIT in people in schizophrenia to date and have observed improvements in some health‐related outcomes such as aerobic capacity, WC and psychiatric symptoms and have demonstrated feasibility. Of these three RCTs, HIIT has been compared with usual care , MICT , and most recently, in the current edition of Acta, to a control group given two HIIT sessions and encouraged to exercise on their own .…”
