By the fast spreading of cheap consumer electronics more and more gadgets appear on

the market to monitor athletes’ performance. Even though numerous electronic devices

have been developed to support cyclists’ and even runners’ efficiency, by now not many

devices have been introduced to the swimming community to monitor and support the

swimmers performance in the pool. My Master’s Thesis is trying to fill in this gap.

I’ve developed an accelerometer based data logger system to acquire data from swimmers

motion. Several tests have been done in the swimming pool of Reggio Calabria with the small, water

resistant prototype that can be worn during swimming. The results have shown that by

using these accelerometer based data the lap times can be precisely measured, and further

more, swim stroke type identification and stroke counting can be performed.

At final part of my thesis, real time data analyzing and wireless communication issues

are being discussed, in order to provide real time data to the coaches outside the pool.
