Summary of studies examining the relationship between leg power and cardiovascular disease in older adults

Authors	Participants	Mean Age ± SD (years)	Design	Leg Power Measure	Findings
Suzuki et al. 2004 (23)	33 male (n=27) and female (n=6) outpatients with stable CHF	60.3 ± 12.7	Cross-sectional	StrengthErgo240 pedal type isokinetic device	Leg power is significantly and positively correlated with peak VO2, anaerobic threshold and an increase in oxygen uptake relative to change in work rate
McDermott et al. 2004 (68)	979 community-dwelling men and women aged 60 years and older with (n=109) and without PVD	With PVD (78.27) Without PVD (73.78)	Cross-sectional analysis of InCHIANTI cohort	Nottingham power rig	↓ leg power in the lower extremities among participants with PVD
McDermott et al. 2008 (69)	424 participants with PVD and 271 participants without PVD	With PVD (71.39 ± 7.56) Without PVD (74.97 ± 8.24)	Cross-sectional	Nottingham power rig	↓ leg power among participants with PVD
McDermott et al. 2012 (70)	434 participants with PVD	75 ± 8.2	Longitudinal mortality outcome	Nottingham power rig	↓ leg power was associated with higher all-cause mortality among participants with PVD
Takata et al. 2007 (71)	697 Japanese men (n=277) and women (n=420)	80	Longitudinal mortality outcome (4 year)	Isokinetic dynamometer	No significant difference was found between leg power and mortality due to CVD in men or women
Saunders et al. 2008 (72)	66 community-dwelling and independently ambulatory men and women with after a stroke	72.10 ± 9.91	Cross-sectional baseline data from an exercise randomized controlled trial	Nottingham power rig	CVD comorbidities were not found to be predictive of leg power
