Bedside Tests of Cardiorespiratory Fitness

Exploring the Utility of Bedside Tests for Predicting Cardiorespiratory Fitness in Older Adults

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.

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 (HGS) 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.

Inclusion Criteria:

• Over 65y
• Independent, community-dwelling

Exclusion Criteria:

• Contraindications to CPET safety criteria
