downstroke /ˈdaʊnstrəʊk /nounA stroke made downwards: he writes the figure seven with a line through the downstroke...- When mean fuselage speed during the upstroke was only 18% of that during the downstroke, stroke frequency was constant with no gliding, so that power output was unchanged throughout descent.
- Therefore if work per stroke stays constant, enhanced drag resulting from greater fuselage speed during the downstroke limits mean stroke speed, and thus the potential for gliding after a stroke.
- First, it causes the hip turn to lead the downstroke.
