The tabata protocol was only studied and rated effective as a 4-minute block. You are supposed to do 20 seconds of all out effort followed by10 seconds rest and repeat eight times.
What are you doing? Running? Cycling? Burpees? I don't even know how you can translate it into 1-minute bouts. You can't just jump into a high intensity activity and then stop. You are just inviting injury. In fact, I even tack on a few extra minutes to my warm up and cool down when I am doing HIIT work.
Also, the benefit and calorie burn comes from your continuing climb in heart rate. The 10 seconds is not enough to fully recover, so each spurt of activity is starting at a higher rate, which helps build capacity. This does not happen in 1 minute, and as I said, you also need to account for warm up and cool down, which should each be at least 5 minutes.
Also, what else are you doing for exercise? High-intensity training is great, but it needs to be mixed in with other types. Tabata training is pretty advanced. Perhaps it is something you need to build up to. If it makes you feel like puking, that's a pretty good indication it is.
I understand you are busy, but I don't think exercising 1 minute four times a day, even if intense, is going to help you reach your goals or provide the basis for a well rounded routine. I would aim for blocks of 10 to 15 minutes a few times a day and vary your training.
