From this study, High-intensity strength training in nonagenarians. Effects on skeletal muscle, the results for nine 90+ year old institutionalized volunteers after eight weeks of high intensity strength training:
- Strength gains averaged 174%
- mid-thigh muscle area increased 9.0%
- gait speed improved 48%
The study concludes that high-resistance weight training leads to significant gains in muscle strength, size, and functional mobility among frail residents of nursing homes up to 96 years of age.
