Abstract - Adapted Tai Chi Chuan for sarcopenic older adults: an evidence-based proposal
Background. The world population is growing and aging. Morbidities associated with aging have increased proportionately, such as sarcopenia, a skeletal muscle disorder.
Problem and aim. Recent systematic reviews and meta-analysis suggest that Tai Chi interventions are effective at counteracting sarcopenia. However, there are still gaps in the description of how they can be more effective. The aim of this study is to provide a Tai Chi protocol, pedagogically adapted by experts and evidence-based from articles that have confirmed improvements in physical function in sarcopenic older adults.
Methods. Based on a recent systematic review and meta-analysis, the findings were analyzed and integrated into a training protocol by Tai Chi and sarcopenia experts. Results. Tai Chi interventions reporting improvements in physical function through tests: Timedup-and-go; 30-second chair; Gait speed; Short Physical Performance Battery; Five-times-sit-to-stand and Three chair-stand. The main intervention characteristics associated with positive outcomes included programs led by Tai Chi experts, using simplified Yangstyle forms with 8–10 movements, 60-minute sessions, practiced five times per week. Based on the evidence synthesis, a 12-week intervention was identified as a pragmatic and effective duration to achieve functional improvements in sarcopenic older adults.
Conclusions. This evidence-based protocol will attempt to provide detailed information so that healthcare professionals can utilize Tai Chi as an intervention for sarcopenic older adults.
