Worked Solution & Example Answer:Figure 1 shows the muscular system while running - Edexcel - GCSE Physical Education - Question 2 - 2018 - Paper 1
Step 1
(a) Muscle
Answer
-
Muscle A: Biceps
- The biceps muscle is primarily responsible for elbow flexion and forearm supination, playing a crucial role in movements that require bending the arm.
-
Muscle B: Hamstrings
- The hamstrings are a group of muscles at the back of the thigh. They play a vital role in hip extension and knee flexion, crucial during activities such as running and jumping.
-
Muscle C: Gastrocnemius
- The gastrocnemius is one of the calf muscles, and its primary role is to facilitate plantar flexion of the foot at the ankle joint and flexion of the leg at the knee.
Step 2
(b) Role of the muscle
Answer
-
Role of Muscle A (Biceps): The biceps are responsible for lifting and pulling movements, essential in various sports and activities.
-
Role of Muscle B (Hamstrings): The hamstrings assist in running speed and stability by controlling the bending of the knee and propelling the body forward.
-
Role of Muscle C (Gastrocnemius): The gastrocnemius aids in running, jumping, and walking by providing a strong push-off from the ground.
