Clinical Trial Summary

A study of 64 older adults over the age of 65y to assess the utility of patient characteristics and bedside measures of physical function and muscle size to predict cardiorespiratory fitness.

Description:

A study of 64 older adults over the age of 65y to assess the utility of patient characteristics (age, gender and BMI) and bedside measures of physical function (handgrip strength and step box test) and muscle size (muscle thickness via B-mode ultrasonography (US)) to predict cardiorespiratory fitness (VO2peak and anaerobic threshold) as measured by the gold-standard assessment method, cardiopulmonary exercise testing (CPET). Each participant will take part in a single assessment day (after health screening against CPET safety criteria) whereby they will have US measures of the vastus lateralis before completing HGS and step box test assessments, and finally a CPET.

Outcome
Type Measure Description Time frame Safety issue
Primary Cardiorespiratory fitness (CRF) - VO2 max CRF via cardiopulmonary exercise testing (CPET). This includes a measure of maximum oxygen uptake (VO2 max) determined via inline breath gas analysis during an incremental cycle test. Single time-point - 8 to 12 minutes
Primary Cardiorespiratory fitness (CRF) - Anaerobic threshold CRF via cardiopulmonary exercise testing (CPET). This includes a measure of anaerobic threshold (AT) determined via inline breath gas analysis during an incremental cycle test. Single time-point - 8 to 12 minutes
Secondary Muscle architecture - muscle thickness Analysis of vastus lateralis muscle thickness using b-mode ultrasonography Single time-point: 10 minutes
Secondary Muscle architecture - pennation angle Analysis of vastus lateralis pennation angle using b-mode ultrasonography Single time-point: 10 minutes
Secondary Muscle architecture - fascicle length Analysis of vastus lateralis fascicle length using b-mode ultrasonography Single time-point: 10 minutes
