In contrast, Maganaris et al. (1998) assessed the moment arm length at varying
ankle joint angles at both rest and during maximal contractions.
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.
During ankle plantarflexion, relative load, knee joint angle,
ankle joint angle and repetition speed all affect calf muscle activity.
Not exact matches
Anatomical factors may include high or low arches, hip
angles or hypo / hyper mobility in foot and
ankle joints.
They capture variables like knee and
ankle angles and
joint torque.
The
ankle joint is at a 90 degree
angle.
This continuous change of
angles and stresses along the
joint will help make your
ankles more resilient and better conditioned for negative stresses down the line.
Bring your arms straight up as you rise into a squat with your right leg bent at a 90 °
angle for Warrior I. Stack the
joints by bringing the knee directly above the
ankle.
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.
As the
ankle joint was moved from 90 degrees (neutral) to 150 degrees (toes pointing down), pennation
angle increased.
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.
