    As we were and as we should be, combined exercise training in adults with schizophrenia: CORTEX-SP study part II
    (John Wiley and Sons Inc, 2024-08) Tous Espelosín, Mikel; Pavón, Cristóbal; Elizagarate Zabala, Edorta; Sampedro, Agurne; Maldonado-Martín, Sara
    Objective: To determine the changes in health-related quality of life (HRQoL) and sleep quality following a supervised combined exercise (EX) program compared to a Treatment-As-Usual (TAU) and to analyze the relationship between the differences in cardiorespiratory fitness (CRF) and HRQoL domains in people with schizophrenia (SZ). Methods: The SZ (n = 112, 41.3 ± 10.4 year) was randomly assigned into a TAU control group (n = 53) or EX-group (n = 59, 3 days/week). The 36-item Short-Form Health Survey questionnaire assessed HRQoL and the sleep quality analysis (accelerometry). Results: After the intervention (20 weeks), physical functioning (∆ = 12.9%), general health (∆ = 15.3%), mental health (∆ = 8.3%), physical component summary (PCS) (∆ = 5.1%), and sleep efficiency (∆ = 1.9%) increased (p < 0.05) in the EX, with no significant changes in the TAU for any domains studied. There were significant differences between groups whose EX showed improvements (p < 0.05) compared to TAU in physical functioning, general health, PCS, and sleep efficiency. A greater CRF was associated with better values in physical functioning, role-physical, bodily pain, general health, vitality, and PCS after the exercise program in SZ. Conclusions: A 20-week supervised combined exercise intervention program for SZ increased sleep efficiency and physical functioning, general and mental health, and PCS scores. This could lead to a critical HRQoL change from how they were to how they should be. Trial Registration: ClinicalTrials.gov identifier: NCT03509597.

    Cross-validation of predictive equation for cardiorespiratory fitness by modified shuttle walk test in adults with schizophrenia: a secondary analysis of the cortex-sp study
    (MDPI, 2021-10-29) Tous Espelosín, Mikel; Ruiz de Azúa García, Sonia; Iriarte Yoller, Nagore; Sánchez Gómez, Pedro Manuel; Elizagarate Zabala, Edorta; Sampedro, Agurne; Maldonado-Martín, Sara
    Cardiorespiratory fitness (CRF) can be direct or estimated from different field tests. The Modified Shuttle Walk Test (MSWT) is suitable for all levels of function, allowing a peak response to be elicited. Therefore, we aimed (1) to validate the equation presented in the original study by Singh et al. for evaluating the relationship between MSWT with peak oxygen uptake (VO2peak) in adults with schizophrenia (SZ), (2) to develop a new equation for the MSWT to predict VO2peak, and (3) to validate the new equation. Participants (N = 144, 41.3 ± 10.2 years old) with SZ performed a direct measurement of VO2peak through a cardiopulmonary exercise test and the MSWT. A new equation incorporating resting heart rate, body mass index, and distance from MSWT (R2 = 0.617; adjusted R2 = 0.60; p < 0.001) performs better than the Singh et al. equation (R2 = 0.57; adjusted R2 = 0.57; p < 0.001) to estimate VO2peak for the studied population. The posteriori cross-validation method confirmed the model’s stability (R2 = 0.617 vs. 0.626). The findings of the current study support the validity of the new regression equation incorporating resting heart rate, body mass index, and distance from MSWT to predict VO2peak for assessment of CRF in people with SZ.
