Subject Demographics and Changes of N‐Acetylaspartate/Creatine Ratios and Phosphocreatine Recovery Time
| Subjects | Gender* | Age (Year) | BMI† (kg/m2) | ∆ NAA/Cr Ratios (Percentage Change)‡ | ∆ PCr Recovery Time, Seconds (Percentage Change)§ |
|---|---|---|---|---|---|
| 1 | F | 69 | 20.34 | .17 (12.85%) | –3.97 (–16.82%) |
| 2 | F | 69 | 26.22 | –.04 (–2.38%) | –26.04 (–53.66%) |
| 3 | M | 70 | 26.56 | .05 (3.78%) | –15.65 (–42.61%) |
| 4 | F | 72 | 23.24 | .08 (5.48%) | –3.54 (–11.33%) |
| 5 | F | 51 | 22.72 | .13 (9.08%) | –4.35 (–16.20%) |
| 6 | F | 51 | 23.62 | .08 (5.27%) | 1.66 (9.56%) |
*F = female; M = male.
†BMI = body mass index.
‡NAA = N‐acetylaspartate; Cr = creatine; ∆ NAA/Cr Ratios = NAA/Crpost‐Tai Chi – NAA/Crpre‐Tai Chi; Percentage Change = (∆ NAA/Cr Ratios)/(NAA/Crpre‐Tai Chi).
§PCr = phosphocreatine; ∆ PCr Recovery Time = PCr Recovery Timepost‐Tai Chi – PCr Recovery Timepre‐Tai Chi; Percentage Change = (∆ PCr Recovery Time)/(PCr Recovery Timepre‐Tai Chi).
