Incorporating Technology Into P.E. Classroom

So I was on pe.links4u and found an article titled Benefits Vs Hindrances of using Technology in Physical Eduction, by Kim McCorquodale. Kim talked to a few physical educators who had brought technology into their P.E. room. The first Brian Hagbo who was traditionally a teacher who just wanted to keep doing what he was doing, finally incorporated technology into his class. He first started using HRM in class, so students could realize the effort that they needed to put forth in order to stay in their HR zone. Brian also used the down loadable software that came with the HRM, and would compute daily points for each student based on students staying in their Max HR zone. The teacher stated that this method was much more objective than how he used to do it. Before he would have to evaluate a student's running effort based on outwardly perceived effort or whether they ran the entire time. This to me sounds like a easier way to not be biased when grading students in class. After reading the article I didn't see any reason for technology to be classified as a hindrance in the classroom. The only thing that would be a hindrance would be the time that it takes to become comfortable with the technologies that you want to include in your classroom.
