Frequently
Asked Questions
From the beginning of
this project many questions have been asked about the Handle. This
document will be updated whenever there are new questions. So, please
check the Frequently Asked Questions from time to time to see any
updates.
What
does the BalancePoint handle do?
The BalancePoint handle is designed to reduce the asymmetry of sweep
rowing. This has benefits both in the athlete's health and rowing
performance.
How
does the BalancePoint handle work?
At the catch, or beginning of the stroke, the BalancePoint handle
enables the rower to have both arms fully extended just like sculling.
When the rower is in this position, the load of the catch is more
evenly distributed to each arm and thus the back and legs The load
distribution benefit is most pronounced in the first 15 or so degrees
of the stroke as well as the last 10 degrees of the stroke.
How
does the BalancePoint handle feather?
So far, explaining the feathering has been more difficult that just
giving it a try. Typically, a rower will go through the motion a
few times and feathering is obvious and easy. Even so, we will attempt
to explain it here.
At the end of the stroke,
the rower pushes down on the handle to extract the blade from the
water. Once the blade is out of the water, the rigger side hand
continues to push downward and the non-rigger side hand is held
from pushing down. By doing this, the grips naturally will rotate
the shaft of the oar, thus feather. During the initial part of the
recovery the hands re-adjust to level. Then the oar comes away from
the body.
How
is squaring the blade with the BalancePoint handle done?
This is a very simple motion. Most people, on their first try, are
surprised to find that the motion is not at all cumbersome. To square
up the blade, the rower simply straightens the rigger side arm prior
to getting to the catch.
Why
is the grip spacing wider than typical sweep oars?
It is not necessarily correct to compare the hand spacing that is
used on traditional straight handles and the BalancePoint handle.
In the absence of any competing constraints, the natural position
is near shoulder width.
With traditional handles,
the constraints are comfort and power application. The further the
hands are spread, the greater the inside arm is bent at the catch
position. Conversely, the tighter the hands are together, the more
cumbersome rowing is at higher stroke ratings. For most people the
grip is narrower than shoulder width.
For the BalancePoint
handle the constraints mentioned above are absent. So, like rowing
an ergometer, the initial position for training is about shoulder
width.
What
are the rigging recommendations?
There exist many philosophies of rigging. Because of this, it is important
to make relative recommendations. It is our belief that the stroke
can be made longer with the use of the BalancePoint handle, and greater
work through the pin will be accommodated. By moving more through
the pin, the retrograde motion of the inboard center of pressure portion
of the blade will be minimized.
We also believe that the BalancePoint handle will allow greater
loads at the catch, because the rower is in a more balanced position
to accept those loads. Therefore different loading amounts will
have to be experimented with.
Can I add a BalancePoint handle to my current
oars?
We currently have retro-fit kits available for Concept2 and Croker
adjustable oars. We are working creating fit-kits for all adjustable
handle oars, and hope to find an easy solution for fitting to fixed
handle oars. Please contact us for
more information.
Is the BalancePoint handle available to everyone?
Yes, we want every rower to be have the opportunity to row with
a BalancePoint handle. We now have production units available for
order. Please contact us to set your
crew up with BalancePoint handles today.
What rules are associated with the use of the
BalancePoint?
For FISA governed regattas, it is important to stay within the guidelines
of the FISA Rules. So from Fédération Internationale
des Sociétés d'Aviron International Rowing Federation:
“Rule 1-
Rowing, Boats, Regattas, Rowers
Rowing is the propulsion of a displacement boat, with or without
coxswain, by the muscular force of one or more rowers, using oars
as simple levers of the second order and sitting with their backs
to the direction of movement of the boat. Rowing on a machine
or in a tank which simulates the action of rowing in a boat is
also considered as rowing.”
The BalancePoint
handle does not change the fundamental motion or leverage of a rowing
stroke, it is merely an ergonomic device that helps the athlete
transfer power to the water.
Is
an oar with a BalancePoint handle still a second order lever?
Yes. The BalancePoint handle does not change the relationship of
the load (water), fulcrum (oar-lock), and force (rower), so it remains
a second order lever.
Is the BalancePoint handle patented?
Yes, the BalancePoint handle is protected by U.S. Patent 6,126,500.
