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. |

Practical implications of the blade analysis |
Here we give some practical conclusions based on the results of blade work analysis made in the previous Newsletters:
The blade must be submersed into the water and force increased quickly after the catch.
More even distribution of a rower’s effort during the drive (i.e. more rectangular force curve) helps to increase the blade efficiency.
These features could provide 4.7% difference in the blade efficiency, which equates to 7s faster time in 2000m race. |
