This randomized controlled trial compared three resistance training load prescriptions—fixed percentage of one-repetition maximum (PBT), rating of perceived exertion (RBT), and last repetition velocity-based training (LRVBT)—in older adults (mean age ∼62 years). LRVBT resulted in a greater increase in four-repetition maximum bench press (12.2 ± 4.9 kg) compared to PBT (6.8 ± 4.5 kg), with no significant differences in back squat strength.
Key findings
- LRVBT led to a greater increase in 4RM bench press (12.2 ± 4.9 kg) compared to PBT (6.8 ± 4.5 kg).
- All groups significantly increased 4RM back squat from baseline (p < 0.001).
- Knee extensor muscle thickness increased more in LRVBT (0.71 ± 0.43 cm) than RBT (0.21 ± 0.42 cm).
- Functional performance improved similarly across all groups.
Why it matters
Understanding the effectiveness of different training load prescriptions can help clinicians design better resistance training programs for older adults, potentially enhancing strength and functional performance.
