19 Questions
Which muscle maintains the same output and timing in both walking and running?
Gluteus maximus
What happens to muscle activity and timing as locomotion speed increases?
Muscle activity increases and onset timing is sooner
Which muscle group propels the hip into flexion during the initial swing phase of running?
Hip flexors
How does the gluteus maximus muscle behave in walking and running?
It maintains the same output and timing in both walking and running
What is the primary function of the hamstrings during running?
Occurring at the hip
How does adductor muscle activity differ in running compared to walking?
Adductors work eccentrically in midstance and midswing in running
What happens to the gluteus medius muscle output amplitude as running speed increases?
It increases
Which muscle's output amplitude increases with running speed?
Gluteus medius
What is the primary function of the hip flexors during running?
To propel the hip into flexion during the initial swing phase
How does adductor muscle activity differ in running compared to walking?
Adductors work eccentrically in running and concentrically in walking
When are the hip adductors active during the running gait cycle?
Throughout the entire running gait cycle
Which muscle group works eccentrically to stabilize the body during midstance and midswing in running?
Hip adductors
Which muscle maintains the same output and timing in both walking and running?
Gluteus maximus
How does gluteus maximus output and timing compare between walking and running?
It is the same in both
What type of muscle activity do the adductors perform during midstance and midswing in running?
Eccentric muscle activity
Which muscle group is active throughout the entire running gait cycle?
Hip adductors
Which muscle's output amplitude increases with running speed?
Gluteus medius
How does the onset timing of muscle activity compare between running and walking?
It is sooner in running
What is the primary difference in muscle activity between walking and running?
Muscle activity is greater in running
Study Notes
- Changes occur in motion requirements and timing of activity as locomotion speed increases.
- Running requires eccentric muscle activity to absorb impact forces and generate power.
- Muscle activity is greater and onset timing is sooner in running compared to walking.
- Gluteus maximus maintains the same output and timing in both walking and running.
- Gluteus medius output amplitude increases with running speed.
- Hip flexors propel the hip into flexion during the initial swing phase.
- Adductor muscle activity is different in running compared to walking.
- Adductors work eccentrically to stabilize the body during midstance and midswing in running.
- Hip adductors are active throughout the entire running gait cycle.
- Hamstrings' primary function during running occurs at the hip.
