Weighted Vests

Question:
Is there any information on the use of weighted vests during exercise? One of my group fitness instructors is wearing a weighted vest when she works out. I am not aware of any special athletic event that she is training for. I think she feels it "burns more calories." Do you have any research on the use of weighted vests?

Just as an update : A recent study looking at speed resisted training wearing weight vests (18.5% body mass), pulling a sled (10% body mass) or un-resisted. The results found no significant differences in sprint time or average velocity over 18.3 to 54.9 m sprints. Likewise no significant differences were found for kinematic stride cycle measures (stride length, stride rate, ground contact time and flight time).The researchers further suggest that the un-resisted group may have presented with the slightly greater performance. (Clark, K.P., Stearne, D.J., Walts, C.T. & Miller, A.D. (2009). The Longitudinal Effects Of Resisted Sprint Training Using Weighted Sleds Vs. Weighted Vests, The Journal of Strength and Conditioning Research, (in publication))
