I saw something similar in a school where I teach. A research project involving a group of children was asked to participate after parental permission and notification and consent were given, detailing the purpose of the project, asking for permission for blood samples and a complete physical given to the child free of charge. The students were awarded gift certificates and other free items such as calculators, CD carriers, and water bottles. The heart monitors were worn during gym class only, and the heart rates were compared prior to and after exercised to measure heart rate resting times. The data was tied to numbers, not names, and was stored that way, so there were no long term consequences of the test, and all information was shared with parents. If you have not given your permission for this testing, I would certainly be upset as a parent that you have not been given any information as to the use of the data, or the confidentiality of the data.
