Effect of Baduanjin Exercise and Resistance Band Training on Sarcopenia in the Elderly: A Randomized Controlled Trial.

Resistance band and mixed exercise groups showed significant improvements in appendicular skeletal muscle mass (ASM) and ASM index (ASMI) within groups after the 12-week intervention.

• Post-intervention within-group comparisons indicated significant improvements in ASM and ASMI in the resistance band and mixed exercise groups (P<0.05).
• The Baduanjin group did not show significant within-group improvements in ASM or ASMI.
• Interventions were conducted 3 times per week for 30 minutes over 12 weeks.
• Sample size was n=20 per group, with 80 sarcopenic individuals total.

Between-group comparisons showed greater increases in ASM and ASMI in the resistance band group compared to the control group.

• Between-group comparisons of change scores revealed greater increases in ASM and ASMI in the resistance band group compared to the control group (P<0.05).
• The mixed exercise group did not show statistically significant between-group differences in ASM and ASMI compared to the control group based on the reported findings.
• All four groups were comparable at baseline before the intervention.

All three exercise groups showed significant within-group improvements in handgrip strength (HGS), gait speed (GS), timed up-and-go test (TUGT), and Short Physical Performance Battery (SPPB) scores.

• Post-intervention within-group comparisons showed that improvements (P<0.05) were noted in HGS, GS, TUGT, and SPPB across all exercise groups, including the Baduanjin group.
• The control group was not reported to show similar within-group improvements in these functional measures.
• SPPB, HGS, GS, and TUGT were all measured before and after the 12-week intervention period.

The resistance band and mixed exercise groups demonstrated greater enhancements in HGS, GS, and TUGT compared to the control group in between-group comparisons.

• Between-group comparisons of change scores revealed that the resistance band and mixed exercise groups demonstrated greater enhancements in HGS, GS, and TUGT compared to the control group (P<0.05).
• The Baduanjin group was not reported to show statistically significant between-group differences in HGS, GS, or TUGT compared to the control group.
• This suggests resistance band and mixed exercise produced superior functional improvements beyond those seen in controls.

The resistance band group showed significantly greater improvements in SPPB balance scores compared to the control group, and Baduanjin specifically enhanced balance.

• Changed balance scores in SPPB and overall SPPB were significantly higher in the resistance band group than in the control group (P<0.05).
• The authors concluded that Baduanjin specifically enhanced balance, though between-group comparisons for Baduanjin vs. control on SPPB balance were not explicitly reported as significant in the abstract.
• SPPB is a composite measure that includes balance, gait speed, and chair stand components.

The study was a randomized controlled trial of 80 sarcopenic elderly individuals assigned to four groups: Baduanjin, resistance band, mixed exercise, or control.

• Eighty sarcopenic individuals were randomly assigned to Baduanjin, resistance band, mixed exercise, or control groups (n=20 each).
• Interventions were conducted 3 times per week for 30 minutes over 12 weeks.
• Outcome measures included ASM, ASMI, HGS, GS, SPPB scores, and TUGT.
• Groups were comparable before the intervention began.
