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 |
---|---|---|---|---|---|---|---|
Lavender and Nosaka [45] | 20 healthy males (10 young, 10 older) | 19 ± 0, 71 ± 2 | 6 × 5 reps eccentric contractions of elbow flexors 40% maximal isometric strength | MIVC Muscle soreness CK Mb Range of motion Limb circumference | ↓* ↓* ↓* ↓* ↓*  ↔  | Not recovered (240-h) ↓ Not given Not given ↓ Not recovered (240-h) |  |
