I’m thinking of creating a HIIT workout that would have a circuit of exercises recorded and sensors placed on the client to record their movement and metabolic activity. The client would workout with the video, and sensors would then be used to give the client feedback if their form was incorrect or if they were not in their target workout zone based on their lactate threshold.
Would this workout be done as part of a training session, with a trainer along, or be something the client would plug into on days they are not working with the client?
What sort of sensors would be used? Are you thinking of an app and a smartphone or fitbit? or things hardwired into the equipment in your gym? Because I think it is harder to be precise if designing it for a range of equipment such as people might use if they were doing it in various locations.
How much does the equipment cost, and is there an incremental benefit to increasing the number of people using the equipment?
So, for me personally (which is, I think the feedback you really wanted, rather than the technical questions you probably already have in your plan for this workout) it might or might not be useful. I do use a fitbit,but I use it in a more macro fashion… it reminds me if I sit and read too long, and to drink more water. I might use a system like this, if I had someone along to help me. But I am not young and not highly tech savvy… you really need to consider the population you serve. I don’t mind tech aides in the workout, but I would not typically use one without personal guidance.
If you are thinking of this for current students you would probably do better talking to them and seeing what they use. If they are younger (having grown up with this stuff) or competitive (typically love and benefit from measurement) you could do well with this.
btw, I did a blog post pondering the philosophical issues of measurement, if you wished to take a look I include a link:
Interesting idea. Proper form, while there is an “ideal,” can also be very individual depending on one’s bony structures and joint structure, so I’m wondering how you would actually measure that. For example, I have an internally rotated femur where it comes into the right hip and then externally rotated tibia. A doctor, two physical therapists, and a yoga therapist all disagree on what “proper” form is for me since the hip, knee and foot don’t like to track together, so I’m wary that a machine would be able to measure and “correct” complex movement.
I saw a clip on facebook that showed snips of a game show. One person, or a group, stand on a line while a wall slowly comes towards them. In the wall, there’s a hole with a strange shape. When the wall comes up to them, they have to shape their bodies to the exact shape of the hole so that when the wall passes by, it passes right around them. So, if the wall has a hole that’s very close to the ground and wide, the team has to lie down flat. If the wall has a hole that’s very tall and narrow, the team (or individual) has to stand tall and sideways. As the players get better, the “wall shape” gets harder – it might be an X shape, or an inverted L, etc.
I’m envisioning “corrective” software like this wall. It can tell you what shape it wants you to get into, and you might be able to imitate that shape, but is that shape actually good for that specific individual? That would be my quandary designing such a software – how to make it actually meaningful and useful, versus a mold that doesn’t work for everyone.
