A pole vault swing-up rack includes a frame body with upper hooks and a lower push bracket. The rack is designed to hang vertically from a horizontal bar—as a pull-up bar—by the hooks. An athlete hanging from the pull-up bar in an upright vertical position may kick his/her legs and torso up to an inverted vertical position to simulate movement of a pole vault. The athlete's shoulders rest against vertical uprights of the rack to maintain the athlete's shoulders and body in front of a vertical plane as in a pole vault movement. A trainer can use the lower push bracket to assist the athlete in the kicking motion. The parts of the rack that come into contact with the athlete may be covered in foam padding and a rubber coating.

A method for consistently placing a crossbar on a pin on a standard used in a vertical distance field event such as high jump and pole vault. The crossbar has a crossbar end with a directional index on at least one surface. In another example embodiment, the crossbar end has a plurality of ordinal indicia alone or with the directional index. A worker notes the placement of the directional index and the ordinal indicia when placing the crossbar a first time. The worker subsequently places the crossbar making sure the directional index and ordinal indicia appear in the same position relative to the standards and relative to the pin on the standard.

A training aid stimulator for providing fast perceptive feedback is disclosed. The training aid stimulator includes a first skin electrode and a second skin electrode both for making electrical contact to the body of a user, a charging module, a discharge module connected to one or more of the skin electrodes for a feedback discharging, and a processor for controlling the charging of a capacitor equivalent to a predetermined first voltage level, wherein the processor further being connected to the discharge module for controlling a feedback discharge of the capacitor equivalent. The stimulator comprises a voltage measurement module for measuring the level of charge of the capacitor equivalent, and the processor is configured for keeping the stimulator ready to discharge by repeatedly measuring the level of charge and by providing a maintenance charging when the voltage over said capacitance equivalent is at or below a predetermined second voltage level.

An adhesive system for increasing the adhesion between a device and the skin of a user. The adhesive system has a first coating component for applying to the device and a second coating component for applying to the skin. The first coating component and the second coating component each have a relatively low surface tackiness. However, upon contact of the first coating component with the second coating component, a relatively high degree of adhesion is obtainable. A method for producing an adhesion effect, a kit, and a use of an adhesive system is also disclosed.

A flexible and self retracting crossbar, which is formed of multiple different separated pieces with an elastic device in between, and has a self retracting pulley device.

Embodiments of the subject invention are directed to a training box or device used by an athlete to practice pole vaulting. The interior region of the training box is open, i.e. the base of the training box does not cover the interior of the device and thus there is no front edge. This invention is used to teach and train athletes pole vaulters who prefer to slide their vaulting poles on the ground instead using the prevailing method which involves carrying a pole as they run towards the box and placing the tip of the pole inside the training box. The training box may include electronics capability for measuring performance characteristics of pole vaulters such as the average speed of a pole.
