Question 7
Mohamed is a high jumper. During the high jump the gastrocnemius and the tibialis anterior work antagonistically to allow movement at the ankle during take-off. (a)... show full transcript
Worked Solution & Example Answer:Mohamed is a high jumper - Edexcel - GCSE Physical Education - Question 7 - 2020 - Paper 1
Step 1
(a) Explain the importance of this antagonistic muscle action to the high jumper.
Answer
Antagonistic muscle action is crucial for the high jumper as it allows for controlled and effective movement at the ankle joint. The gastrocnemius contracts, while the tibialis anterior relaxes, facilitating plantar flexion during take-off. This coordination enables Mohamed to jump higher as the gastrocnemius can exert greater force, pushing him off the ground.
Step 2
Step 3
(d) Explain which one of the fitness tests in Table 6 is the least relevant to Mohamed’s high jump performance.
Answer
The Cooper 12-minute swim test is the least relevant to high jump performance. While cardiovascular fitness is important, high jumping primarily relies on power and explosive strength, which are not specifically evaluated in a swimming endurance test.
Step 4
(e) Describe plyometric training.
Answer
Plyometric training involves exercises that enable muscles to reach maximal force in short intervals of time, with the aim of improving speed and power. This type of training typically includes jump training, bounding, and other explosive movements that enhance muscle elasticity and strength, making it suitable for athletes like high jumpers.
Step 5
(f) Justify one reason why weight training would not be suitable to improve Mohamed’s high jump performance.
Answer
Weight training emphasizes increased muscle mass and strength but may lead to excessive muscle hypertrophy, which could reduce agility and speed necessary for effective high jumping. Therefore, it may not directly enhance performance.
