The Rowing Sensor Aiming at Improving Technique | The Tech Race


Welcome to The Tech Race. In rowing, the difference
between winning and losing can be razor thin. This rowing sensor can make
the difference. Why? (ROWING POWER SENSOR) This technology is key to
collecting data about the rower’s effort,
and with this information, to improve accuracy without
expending unnecessary energy. Nowadays, to reach the Olympic
Games with a good level, you need technology
that helps to train to the most precise level. Training has to be of a very
good quality for the athlete to achieve maximum performance. (ARGENTINA) (BUENOS AIRES) (ARGENTINIAN NATIONAL ROWING
CENTRE) At the National Rowing Centre
in Buenos Aires, we investigate a technology
that measures the frequency, amplitude and movements of
the rower. Technically, it is a row-meter
attached to the boat, and with this technology, we
can measure what happens with each stroke, during
a regatta or whilst training. You can measure the necessary
power, speed, angle of entry and exit of the
oars and boat movement so that the trainer can give
the right feedback. The system is made up of
three parts – the rowlock,
which measures force and angle. An accelerometer that goes
inside the boat, which measures acceleration,
then underneath a propeller, it measures the boat’s speed. (SINCE THE OLYMPIC GAMES
STOCKHOLM 1912, RACES ARE COMPETED
OVER A 2,000M COURSE) With this device we can see
a visual representation of how an athlete performs during
a training session. These variables are sent
to the computer and saved. Depending on the quality of
the data recordings chosen, it could be minutes or hours of
information. (BARON PIERRE DE COUBERTIN, FOUNDER OF THE MODERN
OLYMPICS, WAS A ROWER) In the past,
one would film and repeat, then watch the film
in slow motion, and calculate times on paper
with a stopwatch. Here she’s applying more force
on this oar. Here, the changes in speed
are varying too much to produce a good rowing movement. We will have to go over things. It’s like asking someone
to calculate a square root on paper,
or giving them a calculator. The device measures force
and acceleration on both axes, behind and in-front
and vertical – up and down. It also measures the angle of
entry and exit of the oar in the water. The rowing stroke is divided
into several phases – out of the water
and in the water. That’s when the boat
begins to move. When we slide forwards in the
boat, if we do it quickly, the stroke is annulled. This helps us to become aware
of our propulsion, power and velocity
in the water. (LUCIA PALERMO PARTICIPATED IN
THE OLYMPIC GAMES ATHENS 2004, LONDON 2012 AND RIO 2016) Rowing has been staged at all
the editions of the Olympic Games since Paris 1900. Elisabeta Lipa holds the most
Olympic medals for rowing. Between Los Angeles 1984 and
Athens 2004, she won five gold, two silver and one bronze
medals – successes that can only be
achieved when technique is mastered to perfection. The oar has a key amount of
time between when it is out of the water and the boat
begins to accelerate, that time is crucial in every
single stroke. There are 240 strokes in
each regatta. If we gain 1cm in each stroke,
we would gain 2.5m overall. Sometimes you win by
a centimetre. The difference between a gold
medal or nothing is very small. Every centimetre counts. (THE TECH RACE)
