Normative Values of Muscle Power using Force Plate Jump Tests in Men Aged 77-101 Years: The Osteoporotic Fractures in Men (MrOS) Study.

ABSTRACT:

Objective

To determine normative values for weight-bearing, countermovement leg extension ("jump") tests in the oldest men and characteristics of those not completing vs. completing tests.

Design

2014-16 cross-sectional exam.

Setting

Six U.S. sites from the Osteoporotic Fractures in Men (MrOS) Study.

Participants

Community-dwelling men (N=1,841) aged 84.5±4.2 (range: 77-101) years.

Interventions

N/A.

Measurements

Jump tests on a force plate measured lower-extremity muscle peak power/kg, velocity and force/kg at peak power, with normative values for 5-year age groups and by limitations in moderate-intensity activities of daily living (ADLs) and climbing several flights of stairs.

Results

Jump completion was 68.9% (N=1,268/1,841) and 98% (1,2
