Effect Of Stroke Rate On The Velocity/Time Curve Of A Rowing Shell, John S. Bernfield Aug 1977

Effect Of Stroke Rate On The Velocity/Time Curve Of A Rowing Shell, John S. Bernfield

Kinesiology, Sport Studies, and Physical Education Master’s Theses

The 1976 U. S. Olympic eight oared crew was filmed (16 mm, 70 FPS) rowing six trials each at stroke rates of 37, 39, and 41 st/min. Shell instantaneous velocity was calculated and plotted for positions throughout the stroke cycle and a cubic spline curve fit to these data points. Time and percentage of total time for leg drive, upper body drive, transition, hands and upper body away, seat movement, and blades to water phases of the stroke cycle were determined. In addition, actual stroke rate, boat average velocity, and curve amplitude were calculated for each trial. Data was ...
