Abstract
The Moderate Aerobic Intensity Training (MIT) is used to describe the sleep quality and physical fitness of the elderly schizophrenia whom have insomnia: softness, balance ability and lower limb muscle strength. Method: This study was an quasi-experimental study, we select 30 patients with chronic schizophrenia in a northern psychiatric center in Taipei. The experimental group (EG) received MIT for 12 weeks. Exercise course for 50 minutes three times a week, total have 9 balance training, 10 softness training and 11 lower extremity strength training. The control group (CG) receive treatment as usual. Measurement included sleep quality assessment (SQA) by Insomnia Severity Index Chinese version (ISI-C), nursing daily sleep record and actiwatch (with sleep duration, wake after sleep onset). Functional fitness test (FFT) : Body mass index (BMI), Waist-to-hip ratio (WHR), 30-second chair stand (lower limb muscle strength), seated forward bend (lower limb flexibility), 8-foot up-and-go (static balance), single-leg stand with eyes closed (static balance). A total of five measurement times including pretest, 4th, 8th, and 12th week after exercise, and no intervention in the 16th week after stopping exercise. Results: Data analysis with SPSS version 22.0, using descriptive statistics, independent T test, repeated measure ANOVA, and linear regression for statistical analysis. In the objective of SQA, nursing daily sleep record and actiwatch (with sleep duration, wake after sleep onset) total of five times measurement had no significant differences in both groups. In the subjective evaluation, the ISI-C of EG began to improve at the 4th week (β = -5.667, p =.003) and had significant difference until the 12th week(β= -9.067, p <.001). The ISI-C of the EG decreased after no exercise (β= -2.667, p =.190). The effects of physical fitness, the EG began to be effective in the 4th week after intervention, the most significant benefit reached the peak of the eighth week , and remained flat until the 12th week: 30-second chair stand (β = 5.933, p <.001), 8-foot up-and-go (β = -1.619, p <.001), single-leg stand with eyes closed (β = 6.277, p <.001) and physical fitness continued significant to the 16th week. BMI and WHR had no significant differences due to no diet control. Seated forward bend was improved in both group but no significant difference. Conclusion :This study was a 12-week MIT intervention to improve sleep quality and fitness in patients with schizophrenia. It is recommended that ward routine adjustment of exercise time according to FITT principles and patient mental status, accumulating at least 150 minutes per week, effective exercise improves FFT and SQA.
