This systematic review and meta-analysis evaluated the effects of eccentric overload training (EOT) on lower-limb muscle strength, gait performance, balance, and explosive power in older adults. The analysis included 15 randomized controlled trials with 438 participants. EOT was found to enhance lower-limb strength (SMD = 0.50) and explosive power (SMD = 0.39), indicating its potential benefits for this population.
Key findings
- EOT may enhance lower-limb strength with a standardized mean difference (SMD) of 0.50.
- EOT shows a significant improvement in explosive power with an SMD of 0.39.
- High-frequency training (>2 sessions/week) is more effective for lower-limb strength.
- Long-term training (≥8 weeks) yields greater improvements in strength and power.
Why it matters
Understanding the benefits of eccentric overload training can help clinicians design effective exercise programs for older adults, potentially improving their mobility and overall quality of life. Tailoring training frequency and duration may optimize outcomes.
