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.
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, List et al. (2013) found that increasing load caused peak
ankle angle to become more acute, from no load to 25 % of bodyweight, to 50 % of bodyweight.
During
ankle plantar - flexion, relative load,
knee joint
angle,
ankle joint
angle and repetition speed all appear to affect both gastrocnemius
and soleus muscle activity.
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)
