Provides Immediate Feedback

With Real-time technical feedback and effort measurement, you can make sure you are hitting your targets for technical proficiency and training effectiveness when you need it most: while you are rowing.

 

"This system helped us so much in becoming better technical rowers. We were able to set up our foot stretchers to exactly match the angles at the catch and finish together. Seeing angles, slip, wash, and force measurements made us work on every stroke to be longer, more efficient, and faster. This is the best tool for rowers since the invention of the SpeedCoach."
-Yohann Rigogne
USA National Team Rower

Quantifies Technique

Rowing faster is a game of increments- "quicker catch", "more compression", "less layback", "longer leg drive", etc. Getting a feel for these subjective concepts on the water can take hundreds of hours By Quantifying catch, finish and force application into simple numerical targets, technical changes become much easier to learn and maintain.

 

Measures Training Effort

Achieving peak fitness requires an optimized training load, and the EmPower Oarlock takes the guesswork out of determining training effort. By quantifying work, power and heart rate, you can consistently perform within suggested training zones to maximize physiological training benefits.

"It makes rowing more intellectual, conscious, better control. What we feel is very different from what we really do. This measurement tool is objective."
-Dr. Valery Kleshnev
Founder Bio Row

WHAT CAN YOU MEASURE WITH AN EMPOWER OARLOCK?

 

A COACHING TOOL LIKE NO OTHER

Set Clear Targets for your Athletes

Supplement your words and drills with measureable targets for each rower's technique and capabilities. "Sit up at the catch" becomes, "Catch at 55 degrees". "Row half-pressure" becomes, "Stay between 150-175 watts for 20 minutes".

 

"You certainly have something there that athletes will like! Your system is actually quite a good help for us at this stage. Everything works so easily and without changing anything on the boat, it is indeed helping us!"
-Volker Nolte
Assistant Professor Biomechanics and Coaching and Head Rowing Coach at University of Western Ontario

It's Simpler to use than you think

EmPower oarlock installation is as straightforward as changing a traditional oarlock. Realize noticeable improvements within the course of your normal training sessions.

 

So much more than just Power

Everyone knows that erg power doesn’t correlate exactly with boat speed. Understand WHY and help each athlete maximize their force application through the pin. Synchronize crew power application for maximum effectiveness.

WHAT CAN YOU MEASURE WITH AN EMPOWER OARLOCK?

 

FOUNDATION OF A BOAT-TO-COACH SYSTEM

The EmPower Oarlock serves as a cornerstone component of NK Sports' Performance Measurement Ecosystem. Using it in combination with LiNK Logbook, SpeedCoach GPS, and/or CoxBox GPS, you create the opportunity for boats to stream oarlock data via mobile phone to the cloud for real-time viewing and feedback, or post-workout analysis and review.

Get Immediate Insights

View your athlete’s technique and output while they are rowing. Just stay within shouting distance of your athletes to see their real-time technical and effort measurements.

Go Deeper with Data Review

Review Workout Data on the SpeedCoach GPS to establish targets and monitor your athletes’ performance against them. For even deeper insights, upload workouts to LiNK Logbook and analyze per-stroke data from any portion of the recorded workout.

• Effective Stroke Length
•  
• Average Work
•  
• Current 500m Split
•  
• Slip
•  
• Distance Traveled Per Stroke
•

Measurements
Metric	Units	Range	Notes
Catch Angle	Angular Degrees		Angle of the oarlock when direction of motion reverses from recovery to drive direction.
Effective Length	Angular Degrees		Total degrees traversed by the oarlock between the 100N for sculling/200N for sweep slip and wash thresholds.
Finish Angle	Angular Degrees		Angle of the oarlock when direction of motion reverses from drive to recovery direction
Force	Newtons	to 1/10	The force applied to the oarlock face averaged over the full stroke.
Max/Peak Force	Newtons	to 1/10	The maximum force applied to the oarlock face at any point in the stroke.
Peak Force Angle	Angular Degrees		The degrees of angle at which the peak force occurred in the stroke.
Power	Watts	to 1/10	The rate of work being output. Power can be increased by doing more work per stroke, or taking more strokes per minute.
Average Power	Watts	to 1/10	Power per stroke averaged over the entire interval (if using a SpeedCoach). Resetting the clock will reset the average power.
Slip	Angular Degrees		Angle degrees traversed by the oarlock before the force exceeds 100N for sculling/200N for sweep - a threshold below which the work being done on the oar is doing relatively little to increase the speed of the boat.
Wash	Angular Degrees		Angle degrees traversed by the oarlock after the force drops below 100N for sculling/200N for sweep – a threshold below which the work being done on the oar is doing relatively little to increase the speed of the boat.
Work	Joules	to 1/10	The force times the length of the stroke. Work measures the effectiveness of each stroke.
Average Work	Joules	to 1/10	The average force times the length of the stroke. Work measures the effectiveness of each stroke.
Length	Angular Degrees		Total degrees traversed by the oarlock between catch and finish.
Effective Length	Angular Degrees		Total degrees traversed by the oarlock between the 100N for sculling/200N for sweep slip and wash thresholds.
