Aerobic Fitness Assessment
The body’s ability to deliver and use oxygen during exercise can be used as an indicator as to an individual’s level of cardiovascular fitness. A test to measure this maximal rate of oxygen uptake is preferred, but it is also costly and dangerous for some populations. For these reasons, submaximal testing methods have been developed. The Modified Canadian Aerobic Fitness Test (mCAFT) is one such test. The mCAFT is a ‘step test’ that can be used to predict an individuals maximal aerobic power, while being cost-effective and relatively safe. Instead of pushing clients to 100% of their aerobic capabilities, this test has a maximal heart rate of 85%. This test is made up of several different ‘stepping’ stages, which involve clients stepping up onto a platform, then back down. The CSEP guidelines state that “the more stages you can complete the more efficient your aerobic system” (Canadian Society for Exercise Physiology, 2013). Whether or not a client proceeds to the next stage is dependent upon their heart rate at the end of the previous stage. Once clients reach ≥85% of the heart rate maximum, the test is over and clients perform a cool down. Once the test is complete, the final stage attained and heart rate can be used to indicate the client’s aerobic fitness score, and then determine their health benefit rating.
Our staff use this measure in conjunction with our basic health screening measures to indicate your starting cardiovascular fitness. This measure is a quick test lasting only around 15 minutes and costs $25 to run. It can also be performed for sports teams/groups for a greater cost dependent on numbers, travel time and space allocated. YMCA Cycle Ergometer Test or Ebbeling Single Stage Treadmill Walking Test can be substituted if the participant chooses.
