DEVICE FOR TRAINING SWIMMERS Russian patent published in 2012 - IPC A63B69/12 

FIELD: sport.

SUBSTANCE: claimed invention relates to sport exercise machines, namely to devices for training and improvement of motor actions, psychological stability and volitional preparation of swimmers. Device contains flexible suspension rod and belt fixed on swimmer's body. Rope-pulley system, drive drum is kinematically via redactor is connected with electric engine with one side, and with the other side - with travel sensor, electric engine being connected with control unit outlet and flexible suspension rod being connected in a mechanical way to rope-pulley system via spring-loaded drum, which ensures possibility of its rotation from athlete's effort and automatic return of said drum. In addition, device contains personal computer, stabilised electric energy source, force sensor, pulse detector, formed by sensor, preamplifier and amplifier- HP shaper, from which force sensor and spring-loaded drum are included between rope of rope-pulley system and said flexible suspension rod, sensor of pulse detector is on athlete's body above belt, to which fixed is said rod, connected with force sensor via spring-loaded synchronous drum. Rope part of rope-pulley system is made composite: larger part of its length is supporting rope, and the remaining part is pull-up rope, near which extended is multiple electric thin flexible cable, which is uncoiled and coiled synchronously on three-section drive drum, and pulse detector with USB-port of personal computer, to which also switched is travel sensor, outlet of personal computer being connected with control unit inlet.

EFFECT: increase of device efficiency.
