Abstract
Disclosed is a sprinter training aid which pulls the sprinter forward in an over speed condition, for the purpose of exercise the muscles which pull the leg forward when running, such the hip flexor muscles. Two devices can be used, one pulling the sprinter forward and one pulling the sprinter backward at the start of a run. The backward pulling at the start of the run exercises the sprinter's muscles which are used when going from a stationary position, to a full speed sprint. The device which pulls the sprinter forward would take over when the rearward pulling device shut off, and pull the sprinter to an over speed condition. Include in the device is a cable and cable winder, and a motor, computer, and a wireless connection to a data compilation computer.
Claims22
A sprinter training device, comprising:
- a first motor with a first cable winding reel, configured to let out and take in a first cable to maintain a predetermined line tension;
- a first power source for said motor;
- a first training device frame comprising a mounting position for said first motor;
- a first harness attached to a first end of said cable, for attachment to a sprinter, with said first cable having a second end attached to said first cable winding reel;
- wherein,
- said first motor is configured to pull said sprinter forward toward said first motor by taking in said first cable fast enough to maintain a selected line pressure on said first cable in order to pull said sprinter forward faster than he could otherwise run.

A sprinter training device, comprising:
- a first motor with a first cable winding reel, configured to let out and take in a first cable to maintain a predetermined line tension;
- a first power source for said first motor;
- a first training device frame comprising a mounting position for said first motor and other components;
- a first harness attached to a first end of said first cable, for attachment to a sprinter, with said first cable having a second end attached to said first cable winding reel;
- a first cable feed reel with a first cable measuring unit for tracking how much cable has been pulled out, said first cable feed reel for feeding out first cable from said first cable winding reel;
- a first tensioning arm rotatingly anchored at one end, with said first cable passing over a pulley on a non-anchored end of said first tensioning arm, with said first tensioning arm movable to maintain cable tension constant even if said sprinter's forward progress is of uneven speed;
- a computer for inputting a line pressure to be maintained as said sprinter approaches said first motor and first cable winding reel, and for shutting off said first motor when a measured amount of extended first cable has been retracted;
- wherein,
- said first motor is configured for retracting first cable at a rate to maintain a selected line pressure on said first cable in order to pull said sprinter forward faster than he could otherwise run.

A sprinter training device, comprising:
- a first motor with a first cable winding reel, configured to let out and take in a first cable to maintain a predetermined line tension;
- a first power source for said first motor;
- a training device first frame comprising a mounting position for said first motor;
- a first harness attached to a first end of said first cable, for attachment to a sprinter, with said first cable having a second end attached to said first cable winding reel;
- a computer for inputting a line pressure to be maintained as said sprinter approaches said first motor and first cable winding reel
- a second device frame with a second motor and a second cable winding reel, configured to let out and take in a second cable to maintain a predetermined line tension, with a power source for said second motor, with a second harness attached to a first end of said second cable, for attachment to said sprinter, with said second cable having a second end attached to said second cable winding reel;
- wherein,
- said second motor is configured to pull against said sprinters forward motion away from said second motor, by letting out second said cable fast enough to maintain a selected line pressure on said cable in order to present a rearward pull on said sprinter simultaneous to said forward pull from said cable;
- wherein,
- said first motor is configured to pull said sprinter forward toward said motor by taking in said cable fast enough to maintain a selected line pressure on said cable in order to pull said sprinter forward faster than he could otherwise run, and said second motor is configured to pull said sprinter toward said second motor, with said second motor pulling more at the start of said sprint, and said second motor pulling less at the end of said spring.
