Swimmers improvement is built on rigorous and controlled training. This work aimed to develop a light-weight, practical and low-cost inertial measurement unit (IMU) for swimming monitoring. A 21g device was optimized for including the data acquisition hardware (based on an attitude and heading reference system – AHRS). Eleven male swimmers with different skill levels tested the system under the four different swimming strokes. Based on the AHRS data, three novel indicators were developed: trunk elevation, body balance and body rotation; and anayzed on an individual basis. The proposed unit has unique features to be further explored for training monitoring.
