Effects of movement specific strength training in flat water kayak paddlers
Introduction: Flat water kayaking is a sport where the demands of upper body and core muscle force
and force development is great in comparison to other endurance sports. (Fry and Morton, 1991;
Tesch, 1983) This is mainly due to the fact that race time is relatively short and the water resistance
on the boat is relatively large and increasing with the velocity. This results in the demand of high
force to create and maintain speed of the boat. By this reason it is natural that a large portion of the
paddlers training time is devoted to maximal strength training.
The principle of specificity is central in every sport and flat water kayakers performs strength training
that is as close to the real movement in a paddling stroke as possible. Imitation exercises with free
weights is the most common way, but also training in a paddling apparatus which allows close to
maximal strength training and at the same time resembles the specific movement (Einar model) is
widely used.
It is not to our knowledge been performed studies which compare traditional strength training to
training in the “Einar model”.
Methods: The study was approved by the Norwegian Social Science Data Services (NSD) and all
participants signed an informed consent before entering the study. 16 national level flat water
kayakers, 19 ± 0.0 years with an VO2 max 60.1 ± 0.0 mL∙kg-1∙min-1 participated. Two of the
participants did not complete the study and their data are excluded. The participants had no
previous experience with training in the “Einar model” apparatus as described in this study but well
known with traditional weight training. The study was performed “post season”. All the tests were
performed on the same ergometer (Dansprint, Denmark) and in “pre-season”. The software
Dansprint analyzer (Dansprint, Denmark) was used to evaluate each test regard to paddling
frequency, wattage, velocity, and time. Accumulated VO2 was measured during all tests, and a blood
sample was taken one minute after the tests for lactate measures. Heart rate was measured using a
Polar RS 800 CX, (Kempele, Finland) during the testes. Oxygen consumption was measured using a
Jaeger Oxycon Pro in mixing chamber mode (Jaeger, Germany), and lactate was measured using a
Lactate Scout (Biosen, Germany) device.
Results and conclusion: There was no differences between groups in either of the parameters
measured and the only improvement measured was a significant increase in bench press for both
groups. (p
