Effect of aging on rat morphometric parameters
| Adults (n = 7) | Aged (n = 5) | |
|---|---|---|
| Body weight (g) | 591.7 ± 62.1 | 656.6 ± 57.8 |
| Gastrocnemius weight (g) | 3.4 ± 0.3 | 2.8 ± 0.6* |
| Sarcopenic index (%) | 0.58 ± 0.02 | 0.43 ± 0.10** |
Results, obtained from adult (6 month) and aged (21 month) rats, are expressed as mean ± SD. Sarcopenic index corresponds to the gastrocnemius weight to the body weight ratio, expressed as percentage.
*P < 0.05, **P < 0.01 vs. adult group.
