| Bamman et al. (21) | 9+5=14 | Healthy older adults | Male: 24.60 ± 4.3Female: 25.51 ± 5.7 | 3 | 26 | Knee extensor training at 65-80% of one-repetition maximum | Gender differences in load-induced myofibre hypertrophy among older adults cannot be explained by levels of circulating IGF-1, dehydroepiandrosterone sulphate, or by expression of the myogenic transcripts examined | 5 |
| Bamman et al. (22) | 11+9=20 | Healthy older adults | Male: 27.73 ± 2.9Female: 24.94 ± 4.2 | 2-3 | 26 | Three sets of 80% one-repetition maximum for squat, leg press, and knee extension | Myogenin levels increased in the elderly | 7 |
| Kosek et al. (23) | 13+12=25 | Healthy older adults | Male: 27.81 ± 3.0Female: 25.28 ± 3.0 | 3 | 16 | The resistance training program focused on knee extensors | Muscle hypertrophy was more in men | 6 |
| Leenders et al. (24) | 29+24=53 | Healthy older adults | Male: 27.00 ± 0.5Female: 24.60 ± 0.4 | 3 | 24 | Progressive resistance training | The results were similar in men and women | 7 |
| Mackey et al. (25) | 13+16=29 | Healthy older adults | Male: 25.00 ± 1.3Female: 25.28 ± 1.0 | 3 | 12 | The exercise protocol included three dynamic strength exercises | The results were similar in men and women | 7 |
