New method of kinetic energy evaluation |
A new method of kinetic energy evaluation was recently developed, which is quite simple and requires only the boat velocity, oar angle and seat position data. It was found that about two thirds of the drag energy is spent during the recovery, and only one third during the drive. the new method produces quite reasonable values for kinetic energy, even without force measurements. |

Balance of forces on the boat hull |
Experiments with comprehensive force measurements were conducted recently with new the BioRow instrumented C-bracket mounted on a wing rigger. For the first time, the drag force on the boat was determined directly with BioRow measurements, which can be used for evaluation of rowing technique and equipment quality. |

Rowing Power |
Several scientific articles about rowing power were recently published, which placed doubts upon the standard definitions of this important indicator of performance. The power created between the pin and the oar handle can be called the “Net power”, which is transferred through the oar shaft to the spoon, so this is the only source of energy which moves the rower-boat system forward. Net power transferred from a rower to the external environment is the most important indicator for the evaluation of a rower’s performance. It is measured correctly and reliably with BioRowTel and NK EmPower systems. |
