Astrand & Ryhming Bike Test

What is it?

Maria Figueroa Mayordomo

Aerobic Capacity

A submaximal test

Capacity of an individual to perform certain

exercise is dependent on amount of O2 that is supplied to the muscles

Tests the aerobic capacity (VO2) of an individual by using their measured

Heart Rate & Work Load

Adapted to Oncology Patients

ECG

Calculating VO2 Max

130

bpm

Reliability & Validity of Nomogram

Macsween 2001:

high confidence in extrapolation of submax VO2

Data needed:

HR & Watts

Duration: 6 MIN

Pedling at 50rpm, working pace

Biking for 6 min

Physio takes HR every minute

Average HR from min 5 & 6

Astrand test used in Oncology studies

Thorsen 2005

Adams 2015

Astrand was used to test cardiorespiratory fitness (VO2)

Astrand used to test cardiovascular reactivity during exercise

Experimental group - 14-week exericse program

Control - no program, normal activity

after 4 chemo treatments

HR

Presents Intervention Effectiveness

Treatment Plan & Long-Term Goal

Slowly increase intensity per week to build up

Our Patients vs Normative Values
