Definition of downstroke in English:



  • A 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.’
    • ‘Accelerate 10 feet before the log and time your pedal stroke so your strongest leg will be on the downstroke when you reach the log.’
    • ‘In putting, should you hit the ball on the upstroke, on the downstroke or at the bottom of the stroke?’
    • ‘Be sure the saddle is level and at the right height; you should be able to pedal at the downstroke with your leg extended, but without locking your knee.’
    • ‘Wingbeat frequency was determined by counting wingbeats from the mid point of the downstroke when the wingtip passed below the beak.’
    • ‘Indeed, his sublime, angular downstrokes follow the smooth confidence of his basslines, and he sings with his downcast delivery and dramatic flair.’
    • ‘Alex told me that he has noticed some compulsive behaviors in himself - counting the downstrokes of a bicycle as he pedals it, for example, or going for his long nocturnal rambles about the city.’
    • ‘This structural reinforcement of the major veins may have a mechanical role, possibly related to the phenomenon of wing tip deflection during flight at the end of the downstroke.’
    • ‘In contrast, because the wing membrane of bats attaches to the hindlimb, the downstroke of bats must result in the application of a large upward directed force on the pelvis.’
    • ‘My stance is slightly more than hipwide and my feet are somewhat splayed to create a better thigh sweep and to kick in my glutes and hamstrings during the downstroke.’
    • ‘When the tail is on its way up, the sheath on the bottom side of the tail is stretched, storing some energy for the downstroke.’
    • ‘The powerful downstroke of the wing is powered by the large pectoralis muscles, which also attach to the sternal keel.’
    • ‘As the first powerhouse dive concludes, begin lifting the rod high and reeling on the downstroke, pumping the fish up from the depths.’
    • ‘What's more, without proper ergonomic support, some cyclists's feet (especially those with low arches) may pronate or roll inward on each downstroke, causing excessive rotation that strains the knees, hips and back.’
    • ‘Aerodynamic loads affect the wing throughout the wingbeat cycle, but their influence is most obvious during downstroke.’
    • ‘The use of variation in downstroke and, to a lesser degree, upstroke velocity to maneuver suggests that the evolution of the pectoral girdle was key to both the high power requirements of slow flight and the ability to maneuver during it.’
    • ‘With each downstroke of his wings, he flipped his tail upwards, at about a 45 deg angle.’
    • ‘I'll always be a sucker for that two chord downstroke, no matter how many times it's revisited.’
