Steve Cockerill discuses some of the typical problems
associated with hiking out and takes advice from Fiona Taylor, a
physiotherapist who has often been found in dark corners of Sailing Clubs
at Laser 4000 regattas, with strange men and women complaining of aches
and pains.
The main area of concern for us is our knee; bad knee
pain affects most of us throughout our sailing careers and can often be
the reason for changing to more pedestrian classes sooner than we would
like.
In the majority of cases the source of knee pain is from
behind/under the kneecap (patella). This joint is particularly vulnerable
in sailors because of the loads placed on the joint in the hiking position
and the joint shape that relies on specific muscle activity.
I have seen many young sailors using bad and ineffective
hiking styles that will, if not corrected, store up problems for them in
later life. I am afraid it is a subject that if we do not take seriously
can lead to bar talk like ‘I could not carry on sailing a single-hander,
‘cause my knees gave out’.
Having had an aggravating knee problem myself, I have
been keen to write this article for some time to ensure that we all
develop good, healthy and effective hiking styles and enjoy this physical
aspect of our sport for many years to come. Fortunately for me, I have
changed my techniques, which have in turn helped repair my knee, and as a
bonus improved my speed.
I was diagnosed with chrondromalica patella some 10 years
ago. This condition is common amongst all types of athletes. It basically
means that I had an imbalance in the muscle groups around the knee that in
my case was caused by a bad hiking style. This bad style caused the
muscles to develop in an unbalanced way which caused the knee cap to move
out of track and become inflamed and very painful. When I got tired I had
a natural leaning forward style which involved rotating my aft foot
forward and using the stronger and more stamina resistant outer quadriceps
to maintain the hiking position.
Obviously when we exercise we are going to develop our
muscles, but bad exercises can allow the outer quad to quickly become the
dominant muscle and allow it to pull the kneecap to the lateral or outer
side. The critical aspect of the muscles around the knee cap is their
balance around the joint. The key muscle in the balance and stability of
the knee and yet the hardest to develop and maintain is the inner
quadriceps. This muscle requires much harder work to develop and maintain
but it ensures the balance between the large small angled pull of the
outer quadriceps and the small large angled pull of the inner
quadriceps.
. In serious cases
the only course of action is to purposefully damage the lateral muscle
(lateral release) in order for the other muscles to regain the upper hand
in the control of the kneecap. The other alternatives are to take rest and
anti-inflammatory drugs, which make the pain go away but leaves the knee
prone to further damage, or exercise in specific ways to encourage the
inner quad to develop and re introduce the balance around the knee cap.
Thankfully my case was not too bad, so specific exercises was the key. I
spent 6 months with a piece of elastic looped over the end of my foot and
around a table leg. I had to pull my right foot against the elastic toward
my left foot, with a twisting motion. It caused a few strange looks from
my work mates but this re-educated my inner quadriceps to take control!
When sailing, I had to concentrate to keep my feet pointing outwards,
making the inner quad do more of the straight leg control. This was not
easy! When riding my bike for exercise, I ensured my saddle hight was high
enough to allow for the almost straightening of my leg at the bottom of
each revolution. Not the traditional – can you place your feet on the
floor? I avoided the deep squats when weight training in favour of almost
straight leg quad exercises. Deep squats and bent leg cycling encourage
the development of the outer over dominant quad – not what was
required…
The amazing thing about the correct hiking position is
that it is good for knees. Straight leg hiking provides minimal pressure
on the kneecap and encourages a balanced use and development of both the
inner, outer and middle quadriceps.

Bent leg hiking causes large pressure on the kneecap i.e.
Research has shown that when the knee is fully straight the load placed on
the patella is minimal. However if the knee is bent 30 degrees twice the
body weight is exerted on the joint and at 60 degrees the load exceeds ten
times the body weight.

(probably better known as Fiona Bullmore to many Cadet, 420, Europe and
Laser 4000 sailors)
Bent knee hiking encourages the over development of the
larger outer quadriceps – which in turn leads to its over dominance and
our friend chrondramalesia platella or bad tracking of the platella taking
hold. Bent knee hiking also has a tendency to encourage the side hiking
styles that continues to aggravate the problem. In addition, bent leg
hiking causes more pressure on the foot, which takes not only the weight
of the sailor but the lever effect of the bum drooping style.
Hanging on with the toes drops
the bum!
I would hate to consider the added pressure on the foot
joint with bent knee hiking – perhaps this could be the subject of some
future research.
Many significant changes in hiking style has occurred in
the laser class over the last 5 years. One of the most significant changes
being introduced by Nik Burfoot, (ex world Laser Champion from New
Zealand). I saw Nik pointing his toes with very tight toe straps in his
Laser at a Regatta in 1994.
Under questioning, his explanation was ‘if the leg is
straight then there is no need to hold the toe up to grip the boat. In
fact holding the foot up only makes the hamstrings work against the
quadriceps, which are trying to keep the leg straight.’ …It sounded
feasible so I tried it for myself and progressively shortened my
toe-straps to good success. Try this quick exercise for yourself….. Hold
your leg out in front of you off the floor and point your toes in line
with the straight leg. Then try and pull your foot up to the normal
toe-strap holding position…does your knee want to bend??? In pulling your
foot to the angled position, your hamstrings have been tightened and thus
cause the knee to bend, which relieves the stretch on the hamstrings.
Keeping the hamstrings well stretched is common advice given by
physiotherapists and would also help maintain the straight leg with angled
feet. However, straight leg hiking with pointing feet/toes take less
strain on the foot joint, the kneecap and your quads and relieves the
tightening on the hamstrings. In addition this style also requires the
toe-straps to be tighter which helps the sailor to grip the side of the
boat. The more in contact a single-handed sailor is – the more small body
movements can effectively be transmitted to the mast and de-power the rig.
It follows that to use this style, the toe-straps anchoring point needs to
be as close to the hiking point as possible so that the foot is not
encouraged to ‘hang on’ to the toe-strap but merely is held by the toe
strap. Rooster Sailing has developed a padded toestrap that is ideal for
pointed toe hiking, available for all classes. Unfortunately for Nik
Burfoot, he gave his advice freely to his team-mate Hemmish Pepper, who
also took it to heart and subsequently beat Nik at the New Zealand Olympic
Trials in 1996. An offshoot from this article is a new hiking boot.
Personally I used to use a the well known French rubber boot - it gave
security when pointing my toes. I tried some soft neoprene boots - but
they flet like they would fall off my foot. Rooster Sailing has developed
a neoprene soft type hiking slipper that also provides security and grip
when pointed toe hiking, called the Rooster Hike Boot
