Training status affects peak hip, knee and
shank angles.
However,
shank angles are less vertical in unskilled lifters compared to skilled lifters.
Changing the stance by altering step length or
shank angle during split squats affects hip and knee moments.
The hip extension moments of the front and rear legs were greatest with a more acute
shank angle (60 degrees) and a longer step length (85 % of leg length) and smallest with a perpendicular
shank angle (90 degrees) and a shorter step length (55 % of leg length).
Changing the stance by altering step length or
shank angle during split squats affects hip, knee and ankle angles.
They reported that most acute peak knee angle for the front leg was observed for the longest step length (85 % of leg length) and the smallest
shank angle (60 degrees).
However, increasing
the shank angle to closer to perpendicular (90 degrees) made the peak knee angle of the front leg less acute and made the peak knee angle of the rear leg more acute.
Knee extension moment of the front leg is greatest with a more acute
shank angle (60 degrees) and a shorter step length (55 % of leg length).
The knee extension moment of the front leg is greatest with a more acute
shank angle (60 degrees) and a shorter step length (55 % of leg length).
The knee extension moment of the front leg was greatest with a more acute
shank angle (60 degrees) and a shorter step length (55 % of leg length) and smallest with an overextended
shank angle (105 degrees) and a longer step length (85 % of leg length).
They reported that most acute peak ankle angle for the front leg was observed for the longest step length (85 % of leg length) and the smallest
shank angle (60 degrees).
Split squat stance with a short step length (55 % of leg length) and a perpendicular
shank angle (90 degrees) involves the greatest peak hip angle for both legs.
In the split squat, hip extension moment of the front and rear legs is greatest with a more acute
shank angle (60 degrees) and a longer step length (85 % of leg length).
They noted that the split squat stance with the shortest step length (55 % of leg length) and a perpendicular
shank angle (90 degrees) involved the most acute peak hip angle for both legs.
Exploring the effect of step length and
shank angle during split squats with the rear foot on the ground, Schütz et al. (2014) compared step lengths of 55 %, 70 %, and 85 % of leg length and tibia angles of 60, 75, 90 (tibia perpendicular to the ground) and 105 degrees across both front and rear legs.
The peak ankle angle of the rear leg was independent of
the shank angle.
Hip extension moment of the front and rear legs is greatest with a more acute
shank angle (60 degrees) and a longer step length (85 % of leg length).
Comparing the effects of deadlift technique, Escamilla et al. (2000) did not directly measure peak ankle angle but they found that
the shank angle was different between the conventional deadlift and sumo deadlift styles, being around 4 degrees more vertical in the sumo style than in the conventional style.
Webster thinks he knows what
the shank angle is and that CO2 has pulled the hook, but without knowing the gap he is just floundering around and liable to get barbed up.
Not exact matches
Comparing the effects of squats with different stance widths, Escamilla et al. (2001a) did not report actual peak ankle plantar flexion
angles, but they did report more heavily -
angled shanks in narrow stance squats compared to wide stance squats.
Peak ankle
angle (at the bottom position) was more acute during the deadlift than during the squat (suggesting that the
shank was less vertical in the deadlift than in the squat).
Absolute
angles are those that represent the
angles of the trunk, thigh or
shank relative to the horizontal.
