Name the phases of Gait Cycle |
(see well photo) |
|
|
Actions of muscles during gait cycle |
*Gluteus maximus = MAJOR HIP EXTENSOR *Tibialis ant. = ? *Quadriceps femoris = KNEE EXTENSION (Knee extensor for heel contact at Terminal Swing) *Rectus femoris = HIP FLEXORS & Accelerate the thigh *? = CONTRALATERAL ABDUCTORS OF HIP *Iliopsoas = Accelerate the thigh *Hamstrings (eg:?) = ? *Triceps surae = ? |
|
|
Locations of muscles during gait cycle |
*Gluteus maximus = m. of Gluteal region *Tibialis ant. = ? *Quadriceps femoris = m. of THIGH *Rectus femoris = m. of THIGH *? (CONTRALATERAL ABDUCTORS OF HIP) = m. of ?? *Iliopsoas = m. of ? *Hamstrings (eg:?) = at ? *Triceps surae = ? |

|
Concentric joint power? |
Concentric = generate power (+ive) |
|
|
Eccentric joint power? |
Eccentric = absorb power (-ive) |
|
|
Power |
Power = rate of doing work (in watts) =joint moment x angular velocity = M x ω |
|
|
Power generated (+ive) by? |
• hip (flexors and extensors) • ankle (plantarflexors) |
|
|
Joint power - ankle |
. |
|
|
Concentric vs Eccentric |
• Concentric = generate power (+ive) • Eccentric = absorb power (-ive) |
|
|
Stretch-Shortening cycle |
• Muscle activity: starts eccentric contraction (stretch) thenswitches to concentric contraction (shortening) |
