Abstract(s)
This paper reports the development of a system to
instrument a surfboard aiming to evaluate wave riding
performance. According to the research only 3.8% - 5% of
the total surfing time corresponds to the wave riding
movements, despite of been the surfing goal. The system
developed collects the data from twenty four force sensors
positioned beneath the surfer’s feet using a microcontroller
ATMEGA1280, and determines the surfer’s feet positioning
and Centre of Pressure (CoP). Furthermore, an Inertial
Measurement Unit (IMU) with an ADXL335 accelerometer
and an IDG500 gyroscope provides information of the
surfboard’s position in relation to the gravity force axis. To
store the result of the acquisitions a SD Card is used. To
transmit the data to an external device such as a computer,
a WI-FI module complete the electronic system. A battery
management was used to allow the system to work remotely.
This work presents an overview of the parameter recognized
in literature as influencing athlete’s performance and a brief
description of the major manoeuvres in competition to
figure out the parameters to be measured likewise the
system developed. Preliminary tests with five different
setups have shown that the force sensors to measure CoP
and the electronic circuit board works properly.
