Nielsen-Kellerman Develops First SUP-Specific Energy Expenditure Equation

Back to Press Releases

Boothwyn, PA - April 20, 2015

Boothwyn, PA — In partnership with researchers from the University of Montana, Nielsen-Kellerman (NK) has developed the first SUP-specific calorie equation to calculate energy expenditure for all experience levels of stand up paddlers. More than 100 participants contributed to the study performed on a SUP ergometer, where researchers collected metrics including heart rate, metabolic cost and oxygen consumption to build the predictive equation.

Participants of the study were tracked over nine minutes of paddling at three different intensities to collect data on 11 different metabolic variables and five ergometric variables. The scope of data gathered allowed researchers to devise a precise algorithm that estimates kilocalories within a range of ±1.11 kcal/min 95% of the time.

This exclusive algorithm is available in the SpeedCoach SUP 2 from NK. In addition to stroke rate, speed, glide and other performance measures, the SpeedCoach SUP 2 displays real-time measurement of energy expenditure as both total calories burned and calories burned per hour. Pairing a heart rate belt with the SpeedCoach SUP 2 with Training Pack provides an even more accurate energy expenditure reading and enables heart rate monitoring and logging.

Whether you’re a SUP racer or a fitness paddler, NK has the performance monitoring tools you need on the water.
