•
Cardiovascular training (CVT)
Resistance training (RT)
Combination CVT & RT (CMB)
Control (CONRTOL)
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
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
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
