Answer:
Fast glycolytic fibers use anaerobic metabolism to produce energy which is used by the muscle for high tension contraction but these muscles fatigue quickly.
- It has amount amount of glycogen and have very quick acting myosin ATPase.
Slow oxidative are known as resistant fibers which generates energy(ATP) by the help of aerobic system.
- It depends on the delivery of oxygen and have red fibers which is smallest of all the fibers.
- It is found in marathon runners and its main function is to maintain posture.
Answer:
Adductor complex
Explanation:
The valgus of the knee is also known as the valgus collapse and medial displacement of the knee. It is characterized by an adduction and internal rotation of the hip, usually when it is in a hip-flexed position (the knee actually abducts and rotates externally). It can also be thought of as a knee that expires while you descend on a<u> squat </u>or landing. When standing on one limb, the pelvis on the opposite side usually also falls during the valgus collapse.
Inadequate gluteus / hip strength (lower gluteus, gluteus buttocks, gluteus maximus, external hip rotators), possibly in combination with<u> hyperactive hip adductors</u>, prevents adequate stabilization of the femur. The hips move in adduction and internal rotation. And when the adductors are hyperactive compared to the external buttocks / rotators of the hip, the knee is dragged in a manner similar to the collapse of the valgus.
