+Is “Snoozing” Bad?
http://www.cnn.com/2014/02/06/health/upwave-snooze-button/index.html?hpt=he_t4
+Homework Review
Upper Extremity Worksheet
+Movements of the Hip
What are the movements of the hip? Flexion Extension Abduction Adduction Medial Rotation Lateral Rotation Circumduction
+Muscles of Hip Flexion
Rectus Femoris (quad muscle)
Pectinius
Psoas Major
+Muscles of Hip Extension
Gluteus Maximus
Hamstrings Semimembranosus Semitendinosus Biceps Femoris
+Muscles of Hip Abduction
Tensor Fascia Latae
Iliotibial Band (IT Band)
+Muscles of Hip Adduction
Adductor Magnus
Adductor Brevis
Adductor Longus
+Muscles of Medial/Lateral Rotation
MEDIAL Adductors
Magnus Longus Brevis
Semimembranosus Gluteus Medius
LATERAL Biceps femoris
+Psoas Major
Origin: T12 and lumbar vertabrae
Insertion Lessor trochanter of femur
Action Flexor of hip or thigh on pelvis
+Semimembranosus
(Deep to Semitendinosus)
Origin: Ischial tuberosity
Insertion: Proximal tibia
Action: Extends thigh; flexes knee, medially rotates
+Tensor Fascae Latae
Origin: Iliac crest
Insertion: IT band tract
Action: Medial rotation, abduction
+Tensor Fasciae Latae
+Adductor Magnus
Origin: Ischial and pubic rami
Insertion: Adductor tubercle of femur
Action: Adduct and medially rotate and flex thigh
+Adductor Magnus
+IT Band Syndrome
IT Band connects from the Tensor Fascae Latae to the Lateral knee
Very important in leg stabilization while running
Common injury to the IT band from running, cycling, and heavy squatting
Inflammation caused by continual rubbing of IT band over lateral femoral epicondyle from flexion/extension
+
Quad/Knee/Calf
+Movements of the Knee
What directions does the knee move? Flexion Extension
NO rotation
+Muscles of Knee Flexion
Remember, flexion is the decrease in angle size Heel to butt
3 Hamstring muscles Semimembranosus Semitendinosus Biceps Femoris
+Muscles of Knee Extension
How many muscles are in the quadriceps? 4
Rectus Femoris
Vastus Medialis
Vastus Lateralis
Vastus Intermedius
+Muscles of the Calf (action)
Calf muscles deal with ankle movement Gastrocnemius (plantar flexion)
Crosses ankle and knee Solus (plantar flexion)
Crosses only ankle
Say you have a tight calf, but you are unsure which muscle to stretch. How could you stretch one and not the other? (HINT: Has to do with what joints they cross)

Patella Tendonitis (Jumper’s Knee)
Medial Tibial Stress Syndrome Shin Splints
Achilles Rupture
+Patellar Tracking Syndrome
+Patellar Tendonitis
+Medial Tibial Stress Syndrome
+Achilles Rupture
