Abstract

BackgroundPhysical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons. However, it is not known which of the three types of exercises provide the best effects on physical and cognitive status, and which exercise is preferred by older persons. This study compared the effects of PE, VRE, and BE on balance, muscle strength, cognition, and fall concern. In addition, exercise effort perception and contentment in older persons was evaluated.MethodsEighty-four older persons (n = 84) were randomly selected for PE, VRE, BE, and control groups. The exercise groups received 8-week training, whereas the control group did not. Balance was assessed by Berg Balance Scale (BBS) and Timed Up and Go test (TUG), muscle strength by 5 Times Sit to Stand (5TSTS) and left and right hand grip strength (HGS), cognition by Montreal Cognitive Assessment (MoCA) and Timed Up and Go test Cognition (TUG-cog), fall concern by Fall Efficacy Scale International (FES-I), exercise effort perception by Borg category ratio scale (Borg CR-10), and exercise contentment by a questionnaire.ResultsAfter exercise, PE significantly enhanced TUG and 5TSTS to a greater extent than VRE (TUG; p = 0.004, 5TSTS; p = 0.027) and BE (TUG; p = 0,012, 5TSTS; p < 0.001). VRE significantly improved MoCA (p < 0.001) and FES-I (p = 0.036) compared to PE, and 5TSTS (p < 0.001) and FES-I (p = 0.011) were improved relative to BE. MoCA was significantly enhanced by BE compared to PE (p < 0.001) and both MoCA and TUG-cog were improved compared to VRE (p = 0.04). PE and VRE significantly (p < 0.001) increased Borg CR-10 in all exercise sessions, whereas BE showed a significant improvement (p < 0.001) in the first 4 sessions. Participants had a significantly greater satisfaction with BE than controls (p = 0.006), and enjoyed VRE and BE more than PE (p < 0.001). Subjects in all exercise groups exhibited benefits compared to the control group (p < 0.001).ConclusionsPE provided the best results in physical tests, VRE produced measurable improvements in physical and cognition scores, while BE enhanced cognition ability in older persons. Older persons preferred VRE and BE compared to PE. Both exercises are suggested to older persons to improve physical and cognitive conditions.

Highlights

Physical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons
Post hoc test revealed that Berg Balance Scale (BBS) scores were significantly (p < 0.001) greater after PE, VRE, and BE than before exercise, with the effect size of PE = 1.29, VRE = 1.47, and BE = 1.21
PE, VRE, and BE groups exhibited a significant (P < 0.001) decrease in Timed Up and Go test (TUG) performance time compared with the controls, with the effect size of PE = 1.57, VRE = 1.43, and BE = 1.41

Summary

Introduction

Physical exercise (PE), virtual reality-based exercise (VRE), and brain exercise (BE) can influence physical and cognitive conditions in older persons. Aerobic exercise [19,20,21,22] and resistance exercise [11, 23], both separately and in combination [9, 20], can improve cognition in older persons. Vertebral fractures in performing yoga spinal flexion positions [31], and shoulder injuries during progressive resistance training [32] were reported in older persons. These conditions make PE an inappropriate choice for many older persons that require an exercise program. The multi-domain training is suggested for older persons [12]
