This study reports the development of technology for within-stoke assessment of net force and propulsion and drag in swimming. The first phase was the development of an instrumented, variable resistance, sled towed by a swimmer. The sled measures and transmits at 50 Hz, net force applied to the sled and speed of the swimmer. The second phase was development of an iPad APP that provided video synchronised with the sled data, displayed in a split screen image in soft real time.
