Associations Of Cardiorespiratory Fitness And Muscular Strength With Arterial Stiffness In Older Adults, Emma Elizabeth Albin Jan 2019

Associations Of Cardiorespiratory Fitness And Muscular Strength With Arterial Stiffness In Older Adults, Emma Elizabeth Albin

Graduate Theses and Dissertations

Purpose: To evaluate the independent and combined associations of cardiorespiratory fitness (CRF) and muscular strength (MS) with arterial stiffness (AS) in older adults.

Methods: This cross-sectional study included 427 older adults aged ≥65 years (mean age 72). CRF was assessed by time (seconds) to complete a 400-m walk test and MS by overall grip strength (maximum out of 3 trials on each hand, averaged; Jamar Plus+ 12-064). Carotid-femoral pulse wave velocity (PWV) was used to assess AS (AtCor, Sphygmocor Xcel). High AS was defined as a PWV of 10 m/s or greater, as it has been established as a ...


Associations Of Muscular Strength And Cardiorespiratory Fitness With Bone Mineral Density In Older Adults, Hyunsoo Kim Jan 2019

Associations Of Muscular Strength And Cardiorespiratory Fitness With Bone Mineral Density In Older Adults, Hyunsoo Kim

Graduate Theses and Dissertations

Purpose: To evaluate the independent and combined associations of muscular strength (MS) and cardiorespiratory fitness (CRF) with bone mineral density (BMD) in older adults.

Methods: This cross-sectional study included 353 older adults (189 women and 164 men) aged 65 years or older (mean ages 72 and 71 in women and men, respectively). MS was assessed by grip strength (average of the highest force values after three trials on each hand, Jamar+ digital hand dynamometer, Patterson Medical) and CRF was assessed by the 400-meter walk test (minutes to complete 400-meter walking). Whole-body BMD was measured by dual-energy X-ray absorptiometry (DXA, Hologic ...
