Standing broad jump

[Guest guest]

Gerald Lafon asked:

<The vertical jump seems to be a standard test

when assessing an athlete's physical abilities. How does this test

compare with the standing broad jump which would appear to be much

easier to administer?>

In my opinion, it depends on the purpose of the test. As an

example, if the vertical jump ability of the individual is an

important ability as it relates to success in their sport (volleyball

athlete for example), then that is what should be tested. Conversely,

if the test is used as a test of power and explosiveness (martial

arts for example), either the VJ or SBJ could be used.

At the Milwaukee Fire Academy we have tested the Fire Cadets with

both the VJ and SBJ and then calulated for power. Power output has a

significant correlation to fire fighting abilities while VJ and SBJ

in inches do not. What we found was that the correlations when

expressed in inches were high (0.777) between the two tests, but when

calculated for power and expressed in Watts the correlation became

very high (0.954) between the two. We no longer test the VJ because

the tests were redundant when it came to measuring for power.

Additionally, as Gerald said above, the SBJ is easier to administer.

With the current Fire Cadet class we administer the test weekly in

the weight room on the rubber flooring and the only " special

equipment " we need is a tape measure.

[Note that Russian coaches may also use the standing triple jump and the

ten-step jump from a standing start as field tests - for the full battery

of the sort of tests that they use, consult Ch 6.14 of " Supertraining " . Mel

** I must have an older version (third printing) because 6.14 is

Managing the Training Process. Why a triple jump vs a single jump?

[Yes, the latest edition contains at least 115 pages of additional information

- if you need the year 2000 edition, there are still a few left at very large

discount, especially for anyone who owns the older editions. Contact me at

mcsiff@... if you ever need a copy.

Since those tests are for sprinters, I would assume that the Russian scientists

concluded that multiple step dynamic tests should augment the static start

tests because running involves a static start and subsequent dynamic bounding

actions. Mel Siff]

I am training predominantly judoplayers and soccer players. My soccer

players need to get up higher for headers and they need to get to the

ball more quickly over fairly short distances. My judoplayers need to

explode into throws. I like the SBJ for its ease but need to make

sure this test makes sense.

While we are on the subject, since there are standards for this test

what is the " correct " way to measure the SBJ? Toe to toe? Toe to

heel?

## Mike, your findings are very interesting, I hope you don't mind me

asking, but, which equations did you use to calculate power for VJ and SBJ?
