Further analysis of kinetic energy |
Some crews maintain nearly constant ratio of kinetic energy to measured work per stroke at all stroke rates, but others decrease it at higher rates down to zero and even to negative values. The new method should be perfected to work with all types of rowing techniques, or abandoned. |

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. |
