Running Gait Cycle
Stance –> Absorption, Propulsion
Swing –>Initial Swing, Terminal Swing
Double float
% of running gait makeup
20% double float (2 periods of 10%)
40% stance time
40% swing time
Ankle trends sagittal
DF through mid-stance, then PF through toe-off
Knee trends sagittal
flexion through midstance, then extension through toe-off
flexes until mid-swing
Hip trends sagittal
slight flexion or no change through loading response, then extension through toe-off
thigh position may suggest greater hip extension
Ankle trends frontal
eversion in first half, inversion second half of stance phase
Knee trends frontal
can be some varus or valgus, patient specific
Hip trends frontal
usually adduction through midstance, then abduction through toe-off
Glute max
decelerates hip flexion and initiates hip extension
mostly active at beginning of cycle, begins to activate again after first double float
Glute med
controls hip adduction
mainly active during stance phase
Illiopsoas
hip flexion during initial swing
mainly active during double float
Adductor magnus
assists hip extension
mainly during first 20%
Adductor longus
assists hip flexion
double float is most active
Quadriceps
stability, eccentric flexion control during early stance
mainly active at the beginning of the cycle
Hamstrings
contribute to hip extension in early to midstance
flex knee, then decelerate knee extension during swing
mainly active at end of cycle
Plantar flexors
control dorsiflexion, aid in propulsion
active at beginning at cycle
Vertical ground reaction force parts
slope of line = vertical loading rate
impact peak = when foot hits ground
active peak = during the cycle
shortly after impact, during the first half of the stance phase of running, the ankle usually performs these two motions in the sagittal and frontal planes
dorsiflexion
eversion
