Last week on the blog we discussed swimmers who have low drag but poor propulsion. Not surprisingly we received a lot of emails and tweets asking us to take a look at the opposite situation, where your drag is high but your propulsion is relatively good.
To that end let's
look at a case study involving just such a swimmer who has made some big strides forwards by reducing his drag:
If
you've attended one of our clinics or talks in the UK recently you
might have seen some video footage of Charles showing his legs lying low
in the water when he swims:
This
footage was taken in 2011 and we show it to highlight how your
perception of your stroke might be very different from reality. Charles
felt that his legs were quite low but estimated they were "4-5cm" lower
than they should be. Watching back the video footage of his
stroke, he was quite shocked to see that his legs were sinking by as
much as 60cm (2 ft) beneath the surface.
Charles is a strongly
built triathlete with lots of lean muscle mass. He's a strong cyclist
and runner but finds swimming frustrating and looking at the shot above
it's easy to see why with his legs sinking low in the water, creating a
huge amount of drag. This a classic trait of our Arnie Swim Type,
together with their strong tendency to fight the water with a crossover
of the centre line in front of the head, as we see Charles doing here:
Just
prior to taking this footage Charles swam 42 minutes for 1500m which
(with his competitive mindset) he called "a disaster". Unfortunately it
doesn't matter how fit Charles is, dragging his legs through the water
like that is going to slow him down dramatically.
During our initial video analysis and stroke correction session with Charles we worked on:
-
His exhalation technique into the water, ridding his lungs of excess
buoyancy which otherwise lifts him up at the front and sinks the legs - Improving his swimming posture to remove his crossover in front of the head - Keeping his head low when he breathes - Improving his kicking technique to avoid bending from the knee and scissor kicking the legs wide apart - Slowing down his stroke rate a touch to help him straighten out
the stroke
Charles found that immediately following this session
he dropped his 1500m time to 35 minutes, which was a nice improvement
in a very short period of time.
(Follow this stroke correction process yourself, or the one appropriate for your Swim Type, in our Swim Type Guides here.)
Is Your Athleticism Holding You Back When You Swim?
If
you are an Arnie yourself, you will know how difficult and frustrating
swimming can be despite your natural athleticism. Ironically it's
actually this athleticism that is making swimming harder for you as your
lean muscular legs sink downwards in the water.
If you have
low-lying legs when you swim unfortunately there's no silver bullet to
lifting your legs high, it's going to take diligent and consistent work
on all of the areas of
your stroke we mentioned above. However, be persistent and disciplined,
and the improvements will come:
Two Years Later
Since
that initial consultation in 2011 we hadn't seen Charles until he came
back for a follow-up session with us last week. We were very impressed
with how much his body position had improved since 2011:
Although
he's not yet perfectly horizontal in the water, his body position is
drastically improved and although there's still a slight tendency to
cross over the centre line with the right arm, this is much
improved too:
These
stroke improvements are giving him some very large speed gains. In fact
he recently swam 28½ minutes for 1500m, a full 13½ minutes faster than
two years ago!
As well as consistently working on all the areas
we mentioned above, Charles has found that swimming with a light flutter
kick results in a lower effort than trying to use a minimal two-beat
kick. Although some additional energy is being used in the faster kick,
this is more than offset
by his legs sitting higher in the water.
Some swimmers are
naturally suited to a 2-beat kick, particularly those with good
natural buoyancy and shorter punchier stroke styles. But with such a
dense muscle mass, Charles will always be best served with a light
flutter to help bring his legs higher. This a classic example of why you
must always think of yourself as an individual and not follow a "one
size fits all" approach to swimming.
Persistence And Chipping Away
After
further refining his stroke technique in our follow up session, we are
excited about the improvements Charles will now experience as he
continues to improve his stroke technique. Getting into the 25-26 minute
1500m speed range is a realistic short term goal for him and he's also
aware he will gain another minute or two when he dons his wetsuit for
open water events. This means he should now exit the swim towards the
front of his age-group rather than
coming out at the rear and having to play catch-up on the bike.
So
a big congratulations from us to Charles on the large improvements he's
made with his swimming, it's not been an easy journey but your
persistence and hard work is really starting to pay dividends. Thanks
also for allowing us to share your experiences with the wider world.
