In contrast, peak knee and ankle angles do not differ between straight barbell and farmers» walk bar deadlifts or between conventional and sumo deadlift styles,
while peak knee angles are more acute in hexagonal barbell deadlifts compared to straight barbell deadlifts.
Not exact matches
Using weightlifting shoes and running shoes both lead to more acute
peak ankle angles than using no footwear,
while cues to prevent the
knee from moving forward over the toes lead to less acute
peak ankle angles.
Similarly, Baumann et al. (1988) reported that in lightweight (60 kg) athletes,
peak hip and
knee net joint moments were 260 — 300Nm and 60 — 100Nm, respectively,
while in heavyweight (150 kg) athletes,
peak hip and
knee net joint moments were 560 — 660Nm and 175 — 185Nm, respectively.
The effect of cues to prevent
knee movement over the toes on
peak hip angle is unclear but cues to look downwards rather than upwards lead to more acute hip angles,
while increasing fatigue leads to less acute
peak hip angles.
Exploring the effects of training variables, Kellis et al. (2005) found that joint angles differed between relative loads but did not identify how the individual hip,
knee and ankle joints differed; however, McKean et al. (2010) reported that
peak hip angle was more acute with load compared to no load,
while both List et al. (2013) and Gomes et al. (2015) reported that
peak hip angle became less acute with heavier relative loads.
They report that when performing plantarflexion with the
knee fully extended, the medial and lateral gastrocnemius displayed superior
peak muscle activity with increasing angular velocity,
while the soleus displayed decreasing
peak muscle activity with increasing velocity.
Increasing load and wearing running shoes rather than no footwear appear to lead to more acute
peak knee angles,
while using cues to prevent forward
knee movement over the toes and fatigue lead to less acute
knee angles.
