Enhancing Mobility in Older Adults: A Comprehensive Exercise Study

This study recruited 84 community-dwelling individuals aged 60 and older from the Denver Metro area living independently or in assisted facilities. Participants underwent various exercise interventions including cardiovascular and resistance training, with gait and functional assessments. The study aimed to improve mobility and assess outcomes using a range of measures.

  1. Gait Group Methods

  2. Methods • Subjects • 84 community-dwelling individuals, Denver Metro area: • independent or assisted living • 60 years and older • 39 completed study

  3. Inclusion • Age 60 years and older • Cognitively able to understand directions • Ambulate 50 feet continuously without stopping • Physician approval for participation.

  4. Exclusion • Medical diagnoses limiting physical ability • Active or acute fractures • Myocardial infarctions (MI) • Stroke • Traumatic brain injury within the previous six months • Joint replacements within the previous 12 months • Chronic neurological disorders limiting motion • Individuals using assistive devices were permitted to participate.

  5. Methods • Survey & Consent Forms • Short From (36) Health Survey (SF-36) • Self-Efficacy for Exercise Scale (SEE) • Activities Based Confidence (ABC) Scale • Center for Epidemiologic Studies Depression Scale (CES-D) • Medical Outcomes Study Social Support Scale (MOS-SSS) • Community Healthy Activities Model Program for Seniors (CHAMPS) Questionnaire

  6. Methods • Random Assignment • 1 of 4 groups • Cardiovascular training (CVT) • Resistance training (RT) • Combination CVT & RT (CMB) • Control (CONRTOL)

  7. Methods • Testing measurements • VO2max • Astrand Rhyming Cycle Ergometer Test • 50 RPM, 6-minutes • Nomogram to predict VO2max • Age adjusted • Hand Held Dynamometry (HHD) • 1 Repitition Maximum • Hip extensors, hip abductors, knee extensors, ankle dorsiflexors, ankle plantar flexors, abdominals, paraspinals • 2 trials, 3 second hold, 15-30 second rest between

  8. Methods Intervention: • RT: 8 reps x 3 sets of 60-80% 1RM, 2x/wk • Exercised muscles of trunk, hip, knee and ankle. • CVT: walking or cycling for 30 min at 65-75% HR max, 2x/wk • HR, BP and perceived exertion were monitored • CMB: RT 1x/week and CVT 1x/week. • CNTRL: routine activities

  9. Outcomes Measures • Gait parameters-GaitRite™ system: cadence, stride and step length, single-limb and double-limb support, gait velocity • Forward, self-selected • Forward, fast • Backward, comfortable • Functional Gait: • Emory Functional Ambulation Profile (E-FAP) obstacle course • Timed Up and Go
