View Full Version : Normalizing force data for swimming starts

11-21-2005, 06:44 AM
Hello everyone,

I am a graduate student at Arizona State University doing research on
asymmetrical force production during swimming starts. I would like to ask you
a question about the normalisation of force data. It seems customary to
normalize force data for gait and jumping research. However, studies that have
measured the forces exerted during swimming starts do not normalize the forces
(Breed & McElroy, 2000; Breed & Young, 2003; Guimaraes & Hay, 1985).

I am interested in learning what is the "correct" way of reporting force data,
and if there is something different between swimming starts and the gait and
jumping research that might warrant differences in the treatment of the force
data. Does anyone have any ideas?

One thing to consider is that my study involves a repeated measures design
(every subject performed three start techniques). Therefore, normalizing the
forces may not affect the results; however, I would still like to learn the
best way to report my data.

Thanks in advance for your contributions,
