Good timing guys!
All data can be plotted on graphs against time. This is essential for picking out differences in movement between crew members, measuring speeds of recovery, identifying links between hull motion and crew motion, and all other time-based analysis.
The graphs here show force curves from two coxed fours, both of similar power and experience, but very different in terms of blade entry and coordination of power application. Not surprisingly, the better crew is going around 0.3m/s faster - i.e. 30 seconds over a 2000m course.
A coach can identify these differences in terms of body movement, posture, sequencing of legs, trunk and arms during the drive etc… Other sensors complement the analysis:
Combined with video synchronization, the coach can provide hard copy printouts of traces combined with video stills.
