A limb motion measurement device for swimming training includes a sense glove and a sense shoe able to measure and collect the states of moving hands and feet of a swimmer in a training practice, including strength, displacement, velocity, bearing angle, number of times, frequency and time parameters, and to generate a serial of limb motion data of arm stroking and leg kicking motions. These organized and quantified limb motion data can be transmitted outwards to an external computer for the swimmer to study and to produce useful information of more efficient movements and tempos of swimming techniques. Accordingly, the limb motion measurement device for swimming training can be applied to improve swimming techniques in a scientific way.

A water simulation system may include a tank, a plurality of fluidic inlets, a plurality of fluidic outlets, and one or more pumps. In operation, the one or more pumps may introduce liquid to the tank through the fluidic inlets and draw liquid from the tank through the fluidic outlets. A pressure at the fluidic outlets may be diffused through the tank by an intake diffusion system having an intake box and an intake plate separating the fluidic outlets from the interior of the tank. A liquid flow may be adjusted for creating swift water conditions in a first portion of the tank and a slower current in a second portion of the tank.

A digital-optical tracking device and methods for tracking and timing swimmers are disclosed. The digital-optical tracking device is waterproof and submersible, and includes a stereo optical system that takes digital stereo images of an underwater region. The stereo optical system includes at least two optical elements, each of which forms an image in the stereo image. The tracking methods involve repeatedly determining distances to swimmers by measuring distances between stereo copies of the swimmers in successive, time-stamped stereo images. The methods may use predictive algorithms to determine regions of interest within the stereo images in which the swimmers are likely to be found. Once tracking data is established, it is displayed to the swimmers during their workouts and may be shared among multiple trackers in a peer-to-peer configuration, saved for later reference, and sent to a coach station or stations for real-time analysis.

Technologies are described for aquatic resistance training. An aquatic resistance line may be deployed across the surface of a swimming pool. An aquatic resistance device may be deployed to ride along the resistance line when pulled by a swimmer. The aquatic resistance device comprises offset compression tensioners, each with a wedge-like geometry and a channel for the resistance line. The housing of the aquatic resistance device positions adjacent pairs of the offset compression tensioners into alternating orientation to one another. A mechanical compressor within the aquatic resistance device can force the offset compression tensioners against one another along the axis of the resistance line causing the alternating wedge-like geometries of the offset compression tensioners to force the offset compression tensioners off-axis from one another orthogonal to the aquatic resistance line into a configuration operable to adjustably grip the aquatic resistance line thus providing a resistive training load to the swimmer.
