Performance recording sheet. Procedure Once the tests configuration has been setup, test officials are positioned at both shuttle lines cone B and C and participants are ready, then the test can begin.
Test Procedure Participants begin the test from cone B. When instructed by the audio player, they must run towards cone C this must be reached before the following beep signal and immediately return to cone B before the next signal.
Once cone B is reached, participants then have a second recovery period in which they must jog from cone B towards cone A, and then back to cone B before the commencement of the next shuttle.
In this test the participants are only allowed two consecutive fail attempts before they are withdrawn from the test.
That being, if the individual fails to reach cone C and back to cone B in the allocated time, one fail is issued. If this happens a second consecutive time, then they are eliminated.
Once withdrawn from the test, the individuals score must be recorded. Considerations When conducting the test there are several factors that need to be taken into consideration before you begin.
Some of these include: Individual effort — Sub-maximal efforts will result in inaccurate scores. Test regulation — It is vital to have at least two coaches officiate the procedure to prevent any test misconduct, such as not reaching the end-line before the beep.
Issues with the YYIR tests Whilst the test itself is reliable when performed correctly, it is however subject to several weaknesses.
Regulating the test with large groups becomes somewhat difficult as it is hard to track which athletes have repeatedly failed to reach the end-line before the beep.
Therefore, it is strongly advised that multiple assessors officiate the test. It is shown that test familiarity can impact results, meaning individuals that are unfamiliar with the test procedure may achieve less than optimal scores.
Consequently, test familiarisation is highly-recommended. What now? Disclaimer All information provided in this article is for informational and educational purposes only.

Duncan recognized the potential of this new fad and purchased the Flores yo-yo Corporation and all its assets, including the Flores name, which was transferred to the new company in In yo-yos were banned in Syria , because many locals superstitiously blamed the use of them for a severe drought.
Declining sales after the Second World War prompted Duncan to launch a comeback campaign for his trademarked "Yo-Yo" in with a series of television advertisements.
In a trademark case in , a federal court's appeals ruled in favor of the Royal Tops Company, determining that yo-yo had become a part of common speech and that Duncan no longer had exclusive rights to the term.
As a result of the expenses incurred by this legal battle as well as other financial pressures, the Duncan family sold the company name and associated trademarks in to Flambeau, Inc , which had manufactured Duncan's plastic models since As popularity spread through the s and s, there were a number of innovations in yo-yo technology, primarily regarding the connection between the string and the axle.
Swedish bearing company SKF briefly manufactured novelty yo-yos with ball bearings in In , Kuhn introduced the SB-2 yo-yo that had an aluminum transaxle, making it the first successful ball-bearing yo-yo.
In all transaxle yo-yos, ball bearings significantly reduce friction when the yo-yo is spinning, enabling longer and more complex tricks.
Subsequent yo-yoers used this ability to their advantage, creating new tricks that had not been possible with fixed-axle designs.
For example, a certain type of bearing has an inward facing curved surface, to prevent the string from rubbing on the sides of the yo-yo, which would cause unwanted friction when performing intricate string tricks.
Other manufacturers replicate this with a similar inwardly curved surface, but use minor modifications. Some high-end bearings use ceramic composites in the balls of the bearing, to reduce internal friction, again making for a smoother spinning yo-yo.
Precious materials such as ruby have also been used as a material in prototype ball bearings for its properties such as extreme hardness. The sleeper is one of the most common yo-yo throws and is the basis for nearly all yo-yo throws other than looping.
Keeping a yo-yo spinning while remaining at the end of its uncoiled string is known as sleeping. While the yo-yo is in the "sleeping" state at the end of the string, one can then execute tricks like "walk the dog", "around the world", or the more complex "rock the baby".
The essence of the throw is that one throws the yo-yo with a very pronounced wrist action so that when the yo-yo reaches the end of the string it spins in place rather than rolling back up the string to the thrower's hand.
Most modern yo-yos have a transaxle or ball bearing to assist this, but if it is a fixed axle yo-yo, the tension must be loose enough to allow this.
The two main ways to do this are 1 , allow the yo-yo to sit at the bottom of the string to unwind, or 2 perform lariat or UFO to loosen the tension.
When one decides to end the "sleeping" state, one merely jerks the wrist and the yo-yo "catches" the string and rolls back up to the hand.
Ball-bearing yo-yos with a "butterfly" shape, primarily used for string tricks, frequently have low response or are completely unresponsive, requiring a "bind" for the yo-yo to return.
In competition, mastery of sleeping is the basis for the 1A division. Inexpensive fixed-axle yo-yos usually spin between 10—20 seconds, while the expensive ball bearing yo-yos can spin about 1—4 minutes depending on the throw.
Eventually, wider string gaps and silicone response systems led to the innovation of unresponsive yoyoing, otherwise known as 1A.
Traditional yoyos responsive would return to the hand when one would tug on the string, but unresponsive yoyos behave a little differently.
Instead of returning to the hand when you tug on the string, you have to perform a trick called a "bind. Looping is a yo-yo technique which emphasizes keeping the body of two yo-yos, one on each hand, in constant motion, with or without sleeping.
Yo-yos optimized for looping have weight concentrated in their centers so they may easily rotate about the string's axis without their mass contributing to resistance due to a gyroscopic effect.
In yo-yo competitions, looping both to the inside and outside of the hand with the yo-yo plays a strong role in the 2A division. Two handed or 3A style play involves doing string tricks with two flared bearing yo-yos.
The different mounts in this style are referred to as houses e. Photos from as early as the late s show early yo-yo demonstrators performing very basic Triple A tricks, such as a Sleeper with one hand, and a Trapeze with the other.
While Triple A as a concept has existed for many years, it was not until the debut of Velvet Rolls, coupled with the rise of unresponsive yoyo play, that development began on what is currently considered Triple A.
In the "off-string" technique, the yo-yo's string is not tied directly to the yo-yo's axle, and the yo-yo is usually launched into the air by performing a "forward pass" to be caught again on the string.
However, some players can 'throw down' off-string yo-yos and catch it on the string just as it leaves the end of the string by pivoting the string around a finger as it unwinds, so that the yo-yo is caught on the string.
This is exactly the opposite of a "forward pass", but with the same result. Yo-yos optimized for off-string tricks have flared designs, like the butterfly shape, which makes it easier to land on the string, and often have soft rubber rings on the edges, so minimum damage is inflicted on the yo-yo, the player, or anyone who happens to be standing nearby, should a trick go wrong.
There are also tricks which involve the use of two off-string yoyos at the same time, thrown with the same hand, this is known as "soloham.
In freehand tricks, the yo-yo's string is not tied to the player's hand, instead ending in a counterweight. The counterweight is then thrown from hand to hand and used as an additional element in the trick.
Developed in by Steve Brown , as of freehand is considered to be the fastest-growing style of yo-yo play. Steve Brown was awarded a patent on his freehand yo-yo system, which was assigned to Flambeau Products Duncan's parent company.
When the yo-yo is first released, the gravity and the throw give it translational kinetic energy and necessarily, since the string must unwind, much of this energy is converted into rotational kinetic energy establishing the free move of the yo-yo, and causing it to spin rapidly.Richmond News.
