Table 2 The effect of age on exercise-induced muscle damage in women
From: Recovery from Resistance Exercise in Older Adults: A Systematic Scoping Review
Study | Subjects | Age (years) | Exercise | Main outcomes | Effect of age on magnitude of change | Effect of age on time to recovery | Other findings |
|---|---|---|---|---|---|---|---|
Clarkson and Dedrick [50] | 20 healthy females (10 young, 10 older) | 24 ± 3, 67 ± 5 | 24 reps eccentric contractions of elbow flexors 115% maximal isometric strength | Relaxed elbow angle Flexed elbow angle Muscle soreness CK | ↑* ↔ ↔ ↔ | ↑ ↔ ↔ Not recovered (120-h) |  |
Dedrick and Clarkson [51] | 20 healthy females (10 young, 10 older) | 24 ± 3, 67 ± 5 | 24 reps eccentric contractions of elbow flexors 115% maximal isometric strength | MIVC Muscle soreness Reaction time Movement time | ↑ ↔ ↔ ↔ | ↑ ↔ ↔ ↔ | No significant difference in magnitude of strength loss, but older recovered more slowly |
Ploutz-Snyder et al. [52] | 12 healthy females (6 young, 6 older) | 23 ± 4, 66 ± 5 | 10 × 10 reps unilateral eccentric contractions of knee extensors 75% eccentric 1-RM | Concentric 1-RM Eccentric 1-RM | ↑* ↑* | ↑ ↑ | 12-wk RT programme attenuated declines in muscular strength, losing only 14% (Con) and 12% (Ecc) of 1-RM strength |
