The Finn Sailor
Most people who sail the Finn successfully are of a special
breed. Not only do they have to possess the necessary physique
and strength but also required is a commitment, tenacity and
endurance to get their body and mind into the peak of physical
and mental fitness. Nothing less than this gets a Finn sailor to
the top. Winning at Finn sailing represents a pinnacle of
achievement and there are no short cuts to success. Mental and
physical fitness are as much a part of a top sailors preparation
as sailing technique and racing skill. The tough demands that are
placed on the body and mind during a typical Finn race fully
justify the seemingly excessive preparation that has gone into
producing a world class sailor.
Obviously not all are up to this challenge, but it is
surprising how far one can progress towards the ideal and how
much your racing can improve as a result with just a fraction of
the preparation that the top class sailors put in. The
preparation required consists of three main areas: personal,
physical and mental. Personal preparation is becoming
increasingly important, something as simple as decent
accommodation at a championship can play a vital part in a
successful campaign. Physical fitness is self obvious in its
purposes but understanding the physics of getting fit can aid the
process immensely. Mental fitness has an aura of mystique
surrounding it but getting it right can pay big dividends.
The Finnster is as organised and efficient on the water as off
the water. He wears sensible sailing gear with a high stretch
capability so that he is not restricted in his movements around
the boat and is comfortable at all times. He makes sure he has
all the correct gear on board, including food and drink, writing
implements, sailing instructions where needed and a good watch.
He has also prepared himself fully for the competition, both
physically and mentally.
This section provides an overview of the procedures and
training plans that can be utilised in getting you, your body and
your mind into a fit enough condition to cope with the physical
and mental demands of this most elite of dinghy classes. A better
picture can be obtained by reading 'Mental and Physical Fitness
for Sailing' by Alan Beggs, John Whitmore and John Derbyshire
which covers this material in much more depth.
Physical Fitness for Finn Sailing
Fitness is a complicated subject, but it is a subject that is
important to all sailors; being fit is vital in order to sail at
your best, whatever the weather. However, fitness training must
be given some thought: it is possible to train in the wrong way,
or to train too hard, or not to train enough, and unless you know
a little bit about how the body works, and how it uses energy,
getting the best from your body will be difficult.
The fitness training described below is based upon running,
but the principles can be applied to other forms of exercise such
as cycling or swimming. Running is a good form of all round
training for anybody: it conditions the whole body and it is easy
to do from home (or anywhere else you might be), and needs no
equipment apart from a pair of running shoes and a watch.
Energy
Aerobic Exercise: Sailing needs energy. The liver and muscles
in your body store glycogen, which is broken down to provide
glucose; in a process called oxidation, glucose is 'burnt' to
provide energy. The waste product from this process is
carbon-dioxide which is expelled through the lungs. So, if you
sail or exercise easily and have a good oxygen intake, you can
continue exercising comfortably for long periods. This process is
aerobic activity ('with oxygen').
When you exercise, you need oxygen to provide energy, as
described above. You are only able to take-in oxygen at a certain
rate: this limit is referred to as your maximum steady state and
is determined by your physical condition, i.e. your
cardiovascular fitness. Your cardiovascular fitness determines
how much oxygen you can take in and transport around the body for
use: the more oxygen your body can take in and use, the more
energy you have, i.e. the fitter you are. The object of training
is to raise your maximum steady state limit through the proper
type of exercise.
Anaerobic Exercise: Intense activity (i.e. above your maximum
steady state) causes the metabolic system of your body to change:
the oxidation of glucose to provide energy produces a build-up of
a waste product called lactic acid. The reason for this is that
some of the glucose is broken down without oxygen (because your
cardiovascular system cannot supply sufficient oxygen to maintain
your level of activity). This process is anaerobic activity
('without oxygen').
The result of anaerobic activity is an oxygen debt, and it
occurs fairly quickly. The associated build up of lactic acid
leads to muscle fatigue and cramp. A recovery from the oxygen
debt occurs when (after a reduction in the intensity of exercise)
continued oxygen intake allows the lactic acid to be broken down
into carbon dioxide to be expelled through the lungs. Anaerobic
activity is much less economical than aerobic activity; it has a
strict limit, beyond which you cannot continue. However, this
limit is again extendable by training.
Lactic acid in the blood-stream not only causes muscle
fatigue, but lowers the pH of the blood. Long-term accumulation
of lactic acid, caused by very hard long-term training, adversely
affects the functions of the bloodstream: the results can be
tiredness and a susceptibility to injury or illness.
Fitness Fitness is made up of several elements,
including the energy processes described above, all of which have
to be trained in order for your body to be fit. However, it is
important to remember that the foundation for all-round fitness
is aerobic endurance. The elements of fitness are sometimes known
as the S Factors:
• Training for Stamina = long steady running (aerobic) •
Training for Strength = circuits or weight training for
muscular endurance • Training for Speed = interval
training or Fartlek (anaerobic) • Training for Skill =
sailing practice • Training for Suppleness = flexibility
and stretching exercises
Training
Aerobic training: Your aim is to increase your oxygen uptake.
These training sessions should be at a sufficient speed and
intensity in order to have a training effect on the aerobic
energy system, but not too fast (which would build up a lactic
acid debt and become anaerobic). Through aerobic training you
will improve the efficiency of your cardiovascular system, i.e.
the efficiency with which your body extracts oxygen from the air
and transports it around the body in the blood and then uses it
to provide energy. The heart, which is a muscle just like any
other in your body, becomes bigger and improves its efficiency:
at each stroke it will pump more blood, and the circulatory
system improves. Increased fitness can be measured by the lowered
resting heart-rate that results.
Anaerobic training: Your aim is to increase your tolerance to
oxygen debt and your ability to recover from it. There are
several ways of achieving this but the principle is to
intersperse training at a fast pace (which builds up an oxygen
debt) with gentle steady running to recover. During the fast runs
the amount of lactic acid built up will be determined by the
speed and duration of your running.
Training for strength: Your aim is to build up muscle strength
and endurance.
Training for skill: Your aim is the development of specific
sailing skills.
Training for suppleness: Your aim is the development of
flexibility through stretching exercises.
Training concepts The three concepts important to
training are: 1 Your body will adapt to gradual increases: so
begin training well within your capabilities and gradually
increase the loads as your body adapts. 2 Your body
overcompensates: rather than just adapting to the load asked of
it, your body overcompensates so as to handle a bit more if
necessary. 3 Your body needs time both to adapt and to
recover: adequate recovery time between training sessions is of
vital importance; build in rest-days as part of your training to
allow for this - don’t just go on training hard day after
day.
The Training Plan An all round and thorough
training system should be based upon a balanced combination of
aerobic and anaerobic training. Your training plan will be
different at different times of year to fit in with the sailing
calendar but should include four cumulative stages:
Stage 1. Stamina: development of general aerobic endurance.
Aim for 3 to 4 sessions a week. Begin with 15 minutes gentle
running and aim to gradually increase this to 30 minutes or more
per session. Each session should comprise easy running for the
allotted time; if you are getting out of breath you are running
too fast and you are not training aerobically. Don't worry about
the distance you run - just run for the allotted time, at a
steady pace as described. Stage 1 training should last from one
to three months.
Stage 2. Strength: development of local muscular endurance.
In addition to 2 to 3 sessions of aerobic running a week, add
1 to 2 sessions (of a minimum of 30 minutes) a week of
either circuit training or weight training. The object of this
stage is to build up muscle strength and endurance. In addition
to general exercises, target those muscles which get particular
use in sailing: arms, legs, hiking muscles. Stage 2 training
should last from one to two months.
Stage 3. Speed: development of anaerobic capacity. In
addition to 2 to 3 sessions of aerobic running a week and 1 to 2
sessions a week of circuit or weight training, add 1 session a
week of interval training. This session should comprise, for
example, 5 minutes easy running to warm-up thoroughly, then a 20
minute session made up of 30 seconds of hard, fast running and
then 1 to 2 minutes of easy, steady running (or walking) to
recover; finish off with 5 minutes easy running. The object of
this training is to force the body to build up an oxygen debt in
the 30 seconds of hard running and then recover in the easy
running in between; you are training your body to cope with
anaerobic activity. Stage 3 training should last from four to six
weeks.
Stage 4. Skill: development of specific sailing skills.
Having acquired a basic level of general fitness, strength
and suppleness, maintain your fitness with 2 to 3 sessions of
aerobic running a week (and 1 session a week of circuit or weight
training if required), begin spending more time on the water in
order to work on specific sailing skills. Maintain your fitness
in the same way during the racing season.
Suppleness: development of flexibility through stretching
exercises. This is not a separate stage, but should be
included as part of all training at all stages. Stretching
exercises should be performed before exercise of any sort, both
on land or water. Flexibility avoids injury. Work on all areas of
the body, gently loosening up the muscles and stretching them.
Rest: There should be a period of rest, probably at the end of
the summer sailing season, when you take a complete rest from
racing and training to give your body a total break for recovery.
The Training Sessions Each training session, from
whichever Stage, should go as follows:
1 Warm-up. Raise the pulse rate and begin to warm-up the
muscles by walking/jogging around. Then loosen-up the muscles
with the flexibility exercises. 2 The main training session:
Stamina, Strength, Speed or Skill according the particular Stage
you are on, for the allotted time. 3 Lower the pulse rate by
gentle exercises, as in the warm-up.
Yearly Schedule The following is a suggested plan
to follow throughout the year, using a build-up of the four
stages as described above; it can be adapted as necessary to
suit. Your starting point at the beginning of the plan should be
based upon your level of fitness at the time: adjust the times
and pace of each session accordingly to reflect this. This
schedule is aimed at building fitness through the winter, when
you will probably be sailing less, and then working on more
specific skills and training just prior to the main racing season
in the summer, and then maintaining your fitness throughout the
racing period. Finally, once the season is over, allow your body
a complete rest for several weeks.
NOVEMBER to JANUARY Stage 1 JANUARY and FEBRUARY Stage 2
MARCH Stage 3 APRIL onwards Stage 4
MAY to SEPTEMBER Racing / Maintenance of fitness
OCTOBER REST
Finally Fitness is important; you will not only
sail better, but you will enjoy it more and get more out of it
(as well as putting more into it!) if you are fit. Fitness should
also be thought of as a long-term goal. It is something you build
up over the years, and it will not only benefit your sailing, but
will give you a healthier and better quality of life as a whole,
so its worth aiming for. If you don't try it you'll never know!
Once you have attained a reasonable degree of fitness it is
important not to lose it by sustaining an injury through sailing.
Correct techniques and procedures should be adopted to minimise
the risk of damage whilst sailing. Here, Frank Newton, Chairman
of the IYRU Medical Committee and former Finnster explains the
types of injuries that can be sustained and avoided.
Is There a Finn Specific Sports Injury?
Tennis Elbow, Jumper's Knee, Footballer's Ankle, Javelin
Thrower's and Butterfly Swimmer's Shoulder and Hiker's Knee.
Who's knee? Is this to do with long Sunday walks over the
countryside? No. It is the condition of knee pain associated with
the hiking position in dinghy sailing.
Finn sailing in the early days of the class was nothing like
that of the present day because the rig was not comparable. Stiff
masts, cotton sails without windows and poor control of the boom
made life more difficult for the very early Finn sailor and
probably more painful. The sails improved, visibility improved,
but it was many years before the elevation of the boom could be
controlled with anything like certainty. At that time 'Finn
Sailor's Elbow' was the reward for a gybe when the wedge refused
to adjust itself, and the boom struck the helm smartly on the not
so 'funny bone'!
Today's Finn offers a Rolls Royce ride in comparison, and this
better control of the rig also takes away some of the desperate
last minute excursions outboard. When the sail was far too full,
or rising skywards, rapid leaps outboard with consequent risk of
hyperextension or excessive rotation of tilt of the lumbar spine,
could result in back injury.
Hiking The hiking position itself was always
different in the Finn to those designs with minimal freeboard.
The Laser has to be sailed semi straight-legged with the knees
flexed by about 15 degrees. The Finn offered the possibility of
taking the knee joint to the gunwhale so that in the full hike
the thigh bone lay against the hull side. In this posture knee
flexion was about 90 degrees.
In standing, the Centre of Gravity (CG) acts through a
vertical line that passes by design close to the hip and knee
joints. This results in the muscles working those joints having
to do less work in maintaining the upright position. Evolution
had sought the most energy effective system.
In most sports the athlete is erect. Fully 30 per cent of
young persons have a tendency towards a roughening of the under
surface of the patella (knee cap) which tends to rub against the
underlying lower end of the thigh bone (femur) when working under
a load. This causes the most common 'sports injury' seen in young
attenders at the Sports Injury Clinic.
In the hiking position, be it the full hike as in the early
Finn helm, the Star crew or the Soling crew; or the semi-hike as
in the 470 helm; or the near straight leg hike of the Laser; the
line of action of the CG has moved well away from the knee. As a
consequence the loading on the patella in pressing against the
femoral surface below is altered.
The quadricep muscles, at the front of the thigh, pull
strongly upon the upper edge of the patella to which they are
fastened. This pull is equalled by the resultant pull on the
patella tendon, which anchors the lower edge of the patella to
the top of the shin below the knee. There is, because of the bent
angle of the knee, a resultant force applying the patella
strongly towards the knee joint.
In a relaxed standing position this force may be equal to body
weight, at 30 degrees knee bend from the straight position 2-4
times body weight, and at 40 degrees 6 times, rising to 10 times
at 70 degrees of bend. With a roughened patella surface this will
clearly cause pain in some persons.
Hiking Muscles Whether there is discomfort does not
entirely depend upon whether the patella articular surface is
rough. More it depends upon whether the roughness gets into the
wrong place, and this depends upon the tracking of the patella
along the groove made for it on the lower articular end of the
femur. This tracking is determined by the balance in the action
of the four component muscles of the quadriceps. Three of the
four pull the knee straight but tend to take the patella too far
towards the outside, or lateral side of the knee joint. The
fourth, the medial quads muscle, also pulls the knee straight but
takes the patella towards the inner side of the knee.
There should be a balance. If there is not it is usual for the
outer three to win and for the patella to scrape along the
outside of the groove and cause pain. In such circumstances the
Finn sailor should perform specific physical exercises to improve
the medial quads. Any qualified physiotherapist will teach these
to you. At times a spell of sailing in the Laser dinghy with its
more straight legged hike will be a more enjoyable form of
therapy to enable you to return to the Finn with your medial
quads in better shape, since they benefit from working in a less
flexed position.
Knee Pain Runners are also troubled by Hiker's Knee
in which case it may be called 'Anterior Knee Pain' (AKP), or by
the more old fashioned name of 'Chondromalacia Patella' (which is
more correctly the name for the roughened patella surface).
Biomechanics, the study of mechanical laws relating to body
movement, has shown that runners who excessively 'pronate' the
feet (flat footed) are helped by lifting the inner side of the
foot with an 'orthotic' insert. For every degree the foot
pronates the shin bone rotates inwards along its length by one
degree. This adversely affects the biomechanics of the knee and
the tracking of the patella.
It follows therefore, that in hiking, if the feet are crossed
over one another in the toe straps, as when one is tired on a
long beat, this affect will be the same as a weary runner
pronating his feet and enjoying his AKP. The feet should
therefore be alongside one another and the toe straps positioned
so that the strap is over the ankle rather than the toe end of
the foot. In the case of short persons there should be no element
of the sailor straining to reach straps that are just out of
reach. This will generate a 'pronation effect'. In particular the
aft end of the toe strap should not be in the centreline of the
floor. The straps should be parallel to the mid line of the boat
if the sailor has AKP, and within easy reach.
Low Back Pain The avoidance of Low Back Pain (LBP)
associated with sailing is best achieved by the adoption of
Proper Movement Patterns (PMP) within the dinghy. The lumbar
spine (the spine relating to the low back below the ribs) is the
origin of the most powerful of the muscles concerned with flexion
of the hip joint. Ilios-psoas muscle arises from the five lumber
vertebrae and from the inner rim of the pelvis. It is used to
bring the body inboard from the hiking position, to hold it in
the hiking position, and to lower it rapidly outboard into the
hiking position. It will therefore be working concentrically,
isometrically or eccentrically. It works in conjunction with
Rectus Femoris (RF), which is only one of the quadriceps muscles
to cross the hip joint. RF therefore is a knee extensor in
holding the angle of the knee fixed in hiking, and also helps
Ilios-psoas to move the body inboard and outboard. If the
abdominal muscles are not strong enough they fail in their duty
in holding the body in a fixed position in relation to the
pelvis. The body tends to arch backwards upon the pelvis by an
increase in the hollowing of the lumbar area as a result of the
strong pull of Ilios-psoas. This is the position of
hyperextension. When combined with rotation of the lumbar spine
associated with sheeting the sail, or tilting sideways in an
effort to move weight fore and aft when going over waves, or
worse a combination of all three movements under the stress of
the heavy jacket, then this is a recipe for Low Back Pain. In
older sailor the stress will be upon the front of the spine and
discs, in those still growing upon the rear of the vertebrae
causing stress fractures.
For maintaining a pain free back therefore, the sailor should
avoid hyperextension of the lumbar spine, particularly combined
with rotation and tilt. In other words there should be correct
movement patterns within the boat. Plus a suitable programme of
regular abdominal exercises for the low back.
Hiking Bench During hiking the discomfort that
increases over time is due to the muscles of the abdomen, and of
the quads, being held constantly in a contracted state. This is
'isometric' contraction and is characterised by the muscle
neither shortening nor lengthening as it works. The muscle
becomes so tense that the circulating blood cannot enter the
muscle, which therefore has to work anaerobically with local
accumulation of lactic acid. Ischaemia causes pain. Training to
improve hiking therefore should be aimed at a lesser percentage
of maximum effort. When they can do this the circulation can
enter the muscle which then works aerobically. The best way to
train these muscles is to construct a hiking bench to the Finn
side deck profile and to spend increasing time in the sit-out
position. This will be more effective than spending all your time
running, swimming or doing similar conventional endurance type
training.
Fortunately since the Rectus Femoris muscle helps to control
both the knee flexion and hip flexion it is not constantly acting
isometrically. As it changes its length to help to alter the body
position some fresh blood supply enters the muscle and relieves
some of the quads discomfort.
The Fit Finn Sailor The present day Finn sailor is
fortunate that the configuration and length of Olympic Courses
have changed. The early 2 mile windward leg at major
championships with race durations of over two hours have changed.
The fifteen minute windward leg now entails less long hikes on
one tack. The overall race length of about fifty minutes is
considerably shorter. The sailing technique may therefore become
one in which a more 'semi hike' than 'full hike' position is
adopted for longer portions of the race. Hiking bench training
position should reflect this. The training effect is joint angle
specific.
The avoidance of a Finn Specific Sports Injury will entail
thought being given to the layout and accessibility of controls
and of toe straps to give optimum race biomechanics. Also
required are:
• The adoption of a good flexibility and muscle stretch
programme. • The adoption of Proper Movements Patterns
within the dinghy. • Time devoted to a structured Hiking
Bench Training Programme to minimise isometric muscle discomfort,
which will increase sitting out time.
If you do all these then take care when handling the Finn
ashore that you do not sustain an injury before you launch! An
injury is an injury, is an injury..........
Mentally Fit?
As well as ensuring that your body is as physically fit as
necessary for the level of racing you are taking part in, don't
underestimate the mental fitness that is also required. Although
this a quite a technical and in-depth topic to cover, the basics
will be attempted here.
The level of mental discipline required during an event is
obviously dependent upon the level of the competition you are in.
While you may win every club race in sight, you get to the
Nationals and it all starts falling to pieces. Confidence in your
ability in the key issue here. Confidence in what you know you
can achieve and the unstinting belief that you can maintain that
level of ability without faltering up to the end of the race.
This is often achieved by a relaxed, but positive attitude
towards your sailing - a bit of fun. You need to be able to
channel aggression where is is required, for instance at the
start, but also not to get nervous in the process. Maintain a
calm, straight-thinking mental attitude when under pressure and
control the concentration at the correct level - don't
concentrate too much - it's supposed to be fun!
