How to Choose the Right Step Test for your Athletes and Clients

In this video, Andrew Sellars and Sean Seale discuss step tests.
A step test is a physiologic test of performance used to help assess an athlete’s response to increasing levels of work. There are three main components that make up a step test:
Incremental increase in workload
Predetermined duration of each step
Predetermined and steady increase in intensity
A step test can be used to assess the physiologic response at all level of exercise, including maximal effort if needed. It can be also used as a performance measurement in specific situations.
Step tests are best performed at the beginning of any exercise program, to gather information about the baseline characteristics of the athlete. The test can then be repeated at regular intervals to assess whether the training plan has had the desired effects on the athlete. It can also be used to help identify limiting factors to performance, and help uncover details about athletes who are underperforming. Physiologic data, like Oxygen consumption (VO2) can be measured to help with interpretation of the physiologic response to exercise.
Choosing the right modality for the athlete is important. Ideally, the athlete should be tested in the sport that they will be competing in. With VO2 Master, this is much more practical than it was in the past, as the portability allows for athletes to be tested in ways not possible before. For example, we can now test rowers out on the water, or xc skiers on roller skis on the road.
Short step tests should be reserved for athletes trying to attain maximal results at the highest intensities, or for athletes with sufficient endurance to complete a longer, more detailed test. Parameters that can be assessed through step tests include lactate and ventilatory thresholds, functional threshold power (FTP), VO2 Max, Dfa-alpha.

Does the vo2 master measure fat and carb ratios?

How do I set up the vo2 master to do the bruce protocol? I can only find options for speed increases and not grade.
