Refined balance of propulsive forces |
The determination of the fine balance of propulsive forces in the rower-boat-oar system is important for understanding the exact mechanics of force and power transmission from the blade hydrodynamic forces – to the movement of the system. The main achievement of this study was to obtain the refined balance of propulsive forces in the rower-boat-oar system, which confirms the validity of our models, accuracy of the measurements, and allows further extended studies and optimisation of rowing biomechanics. |

Analysis of Tokyo Olympics results |
A strong cross-tail wind allowed for quick times on Tokyo’s Sea Forest Waterway, despite fairly rough water. Radical changes were observed in the race strategy, which is now much more even. The first 500m split was the fastest in all previous regattas, but now the last section is the fastest. As before, the winners had the most even distribution of efforts during the race. The winners were among the slowest at the first 100-150m after start, but significantly faster than their competitors during the middle of the race. |

Axial force at the blade |
The axial blade force has been determined indirectly, as a difference between the handle and gate axial forces. A new type of force sensor was developed by BioRow, which was inbuilt into a handle of a sculling oar and can measure 4D forces applied to it. As expected, the axial force measured at the handle was significantly higher than at the gate, and the main part (max. 75N) should be related to a real axial blade force. The axial blade force can create up to a 70N braking force with two blades at oar angles 55deg, which is similar to the drag at the boat hull, so it should be minimised. |

Blade work profile during recovery |
Christian Lindig from Chesterton RC in Cambridge, UK asks: “You have looked at blade work profiles and I notice that they show in general a slight dipping of the hand before the catch... Do you see any evidence for this in your data, or is dipping the hands universal across all boat classes?” |

New BioRow developments |
A new template of biomechanical data evaluation has been developed for BioRow biomechanical measurements reports. In addition to comparison with Gold Standard Targets, there is now a statistical evaluation of each important indicator based on its group average and standard deviation, which were obtained from the BioRow database (n>40k) for each boat type.
Our Visual Immediate Feedback System (VIFS) was recognised by rowers and coaches as the most effective tool for technique improvement, because rowers can see in a real time what they are doing in a boat and can correct details of their technique from stroke to stroke. The latest version of our BioRow VIFS is based on a head-mounted displays with inbuilt video receivers and a video transmitter “Video TX”, which can take HDMI or analogue signal from the camera and send it to the goggles. |

News & "Stroke rate and rowing efficiency" |
Rowing Biomechanics and technique are very different at low and high stroke rates. High rates differ by faster rower’s movements and better crew synchronisation, but lower quality of blade work and increased inertial losses. Constant practice of high racing rates during the whole season to maintain racing technique during base training at low rates. It is a good idea to include short 20-30s bursts into long steady-state workouts, which does not create excessive lactate, and even helps to improve aerobic training and lactate utilisation. |

Effect of stroke rate on rowing technique |
Stroke rate is an incredibly important factor of rowing technique, and every time we have discussed biomechanical variables and indicators, we mentioned their dependence on the stroke rate. Previously this topic was scattered around many publications, but here it is summarised in one place to give a clearer and more solid picture. |

More about seat racing for selection |
Three types of factors could be identified in the seat racing for selection: biomechanical, physiological and psychological. The nature of the biomechanical factors of a crew’s efficiency are good synchronisation in a crew, then why do we expect rowers to achieve this in merely a few minutes? From a physiology point of view, there is no reason why good single scullers cannot form a good big boat. Psichologically, athletes perform differently at high stress of official regatta and at lower stress of seat-racing and this should be accounted in selection. |
