High-intensity functional training (FT) and strength training (ST) both improve strength in elders. FT offers superior gains in gait speed and dynamic balance control for daily activities.

Area of Science:

  • Gerontology
  • Rehabilitation Medicine
  • Exercise Physiology

Background:

  • Community-dwelling elders often experience impairments affecting mobility and independence.
  • Physical therapy interventions aim to improve function and reduce disability in this population.

Purpose of the Study:

  • To compare the effectiveness of high-intensity functional training (FT) versus strength training (ST) for improving functional outcomes in disabled elders.
  • To assess gains in impairment, disability, and overall functional capacity between the two training modalities.

Main Methods:

  • A randomized, blinded, prospective clinical trial was conducted with 15 elders (aged 62-85) with lower-limb impairments.
  • Participants completed 6 weeks of either high-intensity functional training (FT) or progressive resistive strength training (ST), with similar home practice and therapist contact.

Main Results:

  • Both FT and ST groups showed significant improvements in lower-extremity strength, with no statistical difference between groups.
  • The FT group demonstrated significantly greater improvements in gait speed and maximum knee torque during chair rise compared to the ST group.

Conclusions:

  • Intensive functional training (FT) yields strength gains comparable to traditional strength training (ST) in older adults.
  • FT provides superior benefits for dynamic balance control and coordination during functional tasks relevant to daily living.
