One Giant Leap are an award winning company from New Zealand who develop power measurement technology for paddlesports.
It all started at the University of Canterbury in 2008 and continued with the New Zealand Canoe Sprint team having exclusive rights to use the power meter technology for the build-up to the London 2012 Olympics. Fast-forward to today and One Giant Leap power meters are used by multiple national federations and individual athletes at all levels around the world.
Unlike heart rate monitors, which measure the body’s response to intensity, or GPS boat speed measuring devices and stroke rate sensors, which are affected by environmental conditions (water current, wind speed, water density & water temperature), a power meter provides you with a direct measure of your energy output.
This direct and objective measure of intensity is immediate and power values can be compared from day-to-day, independent of environmental conditions, equipment (boat, paddle length & blade type) and paddling technique.
What is a Canoe/Kayak Power Meter?
A Kayak Power Meter is a 100% carbon-fiber kayak shaft which has been instrumented with force and motion sensors in order to measure the power-output, force and stroke-rate of a paddler.
Feedback as you Paddle
As you paddle your Power, Power Balance (left stroke vs. right stroke power distribution) and Cadence (stroke-rate) will be displayed in real-time on any compatible ANT+ display, updated every second.
Garmin Forerunner 310XT, 910XT, 920XT; Garmin EDGE500, EDGE510, EDGE520; Suunto Ambit2 (S); Samsung Galaxy S3, S4, S5 & S6 and many, many more.
High Speed Data – Pro Models Only
A Detailed View of Individual Strokes
View your stroke profiles – power, pushing hand force & pulling hand force during each stroke – at 50 samples a second.
Identify Left and Right Stroke Imbalances
Imbalances in power and imbalances in hand forces between the left and right strokes highlight weaknesses or an improper paddle offset. Symmetry is important for compatibility with other athletes in a team boat, and it is the key to achieving a smoother boat run. High Speed Data will uncover whether any imbalances exist.
Investigate Stroke-Timing in a Crew/Team Boat
A team boat will perform at its best when each athlete is paddling in time with the rest of the crew. High Speed Data will show you the catch and exit timing of every athlete in the boat who is using a power meter.
Measure and track your energy output with a power meter
Take the Uncertainty Out of Your Training Sessions
With a power meter you can determine the training levels (relative to your Functional Threshold Power) which correspond to each of your physiological energy systems. Using the real-time power feedback you can keep to the correct intensity and maintain quality throughout your session.
Reduce Your Chance of Over-training or Under-training
Using a power meter for every paddling session allows you to quantify and monitor the training stress (training load) that your body was subject to during training and racing. This information can inform you or your coach whether you need to focus on recovery (to prevent injury or illness) or increasing your training load.
Accurately Monitor Your Level of Fitness
With a power meter you can perform fitness testing whenever you want, regardless of the environmental conditions (wind speed, water current, water density & water temperature) and boat setup. You can track your fitness throughout the season and across durations (e.g. ’10s Max Power’, ‘4min Max Power’ & ’20min Max Power’).
Convert More of Your Power Output into Forward Motion
Using a power meter you can find a more efficient technique by monitoring your boat speed and power output whilst adjusting your technique (requires consistent environmental conditions). The more efficient technique will either convert more of your power into forward motion or allow you to maintain the same boat speed with less power.
For Pacing During Training and Racing
Knowing your maximum average power and learning how to pace off that number can lead to better race-day performance! Don’t blow up in the first 25% of the paddle because you can paddle faster at the beginning. Pacing can delay the onset of fatigue from endurance events and allow for a faster average speed.
Allow Your Coach to View Your Training Under a Microscope
Having a recorded power file from a training paddle or race can give your coach greater insights into your physical capabilities. A 2 hour paddle at 200 watts is very different from a 2 hour paddle at 150 watts. Now your coach can have a better understanding of your training and see the details of each paddle as though he/she was right there with you.

Frequently Asked Questions
What is the added weight of a power meter shaft over a regular shaft?
The added weight to the shaft (standard 5cm ) is less than 100g. The majority of the weight is located at the centre of the shaft and for this reason the extra weight is difficult to detect. Many of our customers train and race with their power meters and don’t consider the added weight an issue.
Can I change the blades on a power meter shaft once they have been attached?
Yes, you can use more than one blade set with the power meter. Whilst the shaft is cut to a specific length (which you specify), the shaft length has 5cm of adjustment. Different blades will vary in length somewhat, so the reassembled paddle may have a different overall paddle length, but this will not affect the performance of the product.
What are the International Canoe Federation rules for using a power meter in competition?
Article 8.4 of Chapter 1 (General Regulations) of the 2015 International Canoe Federation ‘Canoe Sprint Competition Rules’ states the following with regard to using a power meter in a Canoe Sprint competition:
‘A boat or competitor may be equipped with a device which provides real time feedback on performance for use by television or event presentation. The device may be used by the competitor for analysis following a race but in no circumstances may the device be used to provide real time feedback to a competitor during a race.’
With this being said, there is no mention of whether the use of ‘a device which provides real time feedback’ is not permitted in the disciplines of Canoe Slalom, Canoe Marathon or Canoe Ocean Racing
How does the power meter measure power?
Firstly, the power meter calculates the force applied to the paddle by the athlete’s hands. The strain gauges in the power meter are located in an arrangement that allows the top (pushing) hand and the bottom (pulling) hand forces to be measured individually.
Secondly, the power meter calculates the velocity at the hands by sampling rotational velocity and acceleration data from the IMU (Inertial Measurement Unit) located inside the shaft.
Power is calculated by multiplying the force of each hand by the velocity of each hand.
