Interpretive Summary: Strength or resistance training (weight lifting) is consistently shown to improve muscle strength in older adults. Whether strength training can reduce muscle fatigue in older adults with demonstrated mobility-limitations remains unclear. We assigned older men and women with mobility limitations (slow walking speed) to 12 weeks of strength training or flexibility training. Older adults receiving strength training had significant improvements in their ability to resist muscle fatigue compared to the group receiving flexibility training. Twelve weeks of strength training in mobility limited older adults significantly improved fatigue resistance as well as muscle strength.

Technical Abstract: Background: Progressive resistance training (PRT) is consistently shown to improve muscle strength in older adults. The efficacy of PRT to improve muscle fatigue in older adults with demonstrated mobility-limitations remains unclear. Methods: Mobility-limited (Short Physical Performance Battery (SPPB)
