A 25-year-old athlete is competing in a 1500m running race. The race requires a sustained aerobic effort with short bursts of anaerobic activity during overtaking and the final sprint.
b. Outline how ventilation changes from rest to the final sprint of the 1500m race, and explain the physiological mechanisms that cause these changes.

This unit introduces students to principles used to analyse human movement from a biophysical perspective. Students use a variety of tools and coaching techniques to analyse movement skills and apply biomechanical and skill-acquisition principles to improve and refine movement in physical activity, sport and exercise. They use practical activities to demonstrate how correctly applying these principles can lead to improved performance outcomes. Students consider the cardiovascular, respiratory and muscular systems and the roles of each in supplying oxygen and energy to the working muscles. They investigate the characteristics and interplay of the three energy systems for performance during physical activity, sport and exercise. Students explore the causes of fatigue and consider different strategies used to postpone fatigue and promote recovery.
In this area of study, students explore the various systems and mechanisms associated with the production of energy required for human movement. They consider the cardiovascular, respiratory and muscular systems and the roles of each in supplying oxygen to, and creating energy at, the working muscles. They examine the ways in which energy for movement is produced by the three energy systems and the associated fuels used for physical activity, sport and exercise of varying intensity and duration. Students also consider the many factors contributing to fatigue, nutritional tools to delay fatigue and recovery strategies used to optimise the return to pre-exercise conditions. Through practical activities, students explore the interplay of the energy systems during physical activity, sport and exercise.
