Worked Solution & Example Answer:Examine the importance of the respiratory system during the phases shown in Figure 7 - Edexcel - GCSE Physical Education - Question 13 - 2019 - Paper 1
Step 1
Importance of the respiratory system during a serve
Answer
During a serve, the respiratory system is crucial for providing oxygen to the muscles that perform the explosive actions required. As players exert maximum effort, the demand for oxygen increases rapidly. The lungs must efficiently supply oxygen while removing carbon dioxide, which builds up due to increased muscular activity. Proper functioning of the respiratory system ensures that the player can maintain power and precision in their serve.
Step 2
Importance of the respiratory system during a long intense rally
Answer
During a long intense rally, the respiratory system plays an essential role in sustaining aerobic metabolism. As the rally progresses, the body continuously utilizes oxygen to produce energy. The rate of breathing increases to facilitate larger volumes of oxygen entering the bloodstream, thereby supporting prolonged muscular activity. If the respiratory system cannot keep up with the oxygen demand, players may experience fatigue, negatively impacting their performance.
Step 3
Importance of the respiratory system while resting between games
Answer
Resting between games allows players to recover. During this recovery phase, the respiratory system remains important for replenishing oxygen levels and clearing carbon dioxide accumulated during play. Adequate rest and effective breathing techniques help restore the player's energy, preparing them for the next phase of the match. If the respiratory system were to function inefficiently during this period, recovery may be compromised, affecting overall performance.
