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.
