Essay Question: To what extent does aerobic exercise improve athletic performance?

(Point) Aerobic exercise plays a crucial role in improving athletic performance by enhancing the efficiency of the cardiovascular system. (Evidence) For example, endurance training such as long-distance running has been shown to increase an athlete’s VO₂ max, which measures the maximum amount of oxygen the body can use during exercise (Bassett and Howley, 2000). (Explanation) An increased VO₂ max allows more oxygen to be delivered to working muscles, enabling athletes to sustain higher intensities of exercise for longer periods without fatigue. This improved oxygen delivery also delays the onset of lactic acid build-up, directly enhancing endurance and overall performance during prolonged physical activity. (Link) Therefore, aerobic exercise is a key factor in improving athletic performance, although its impact must be considered alongside other components such as strength training and recovery. (Point) Ambition is presented in Macbeth as a dangerous force that ultimately leads to destruction. (Evidence) This is evident when Macbeth admits that he has “no spur / To prick the sides of my intent, but only / Vaulting ambition,” acknowledging that ambition alone is driving him towards murdering King Duncan (Shakespeare, 1606). (Explanation) This metaphor suggests that ambition is uncontrollable and reckless, as it “vaults” beyond moral limits and falls on the other side. Shakespeare uses this moment to show that Macbeth is fully aware of the consequences of ambition, yet chooses to pursue power regardless, which makes his downfall self-inflicted rather than unavoidable. (Link) Therefore, Shakespeare portrays ambition not as a noble quality, but as a corrosive force that propels the tragic collapse of the protagonist.
