Submit your answer above to receive instant AI-powered marking and personalised feedback.
In this unit, students’ participation and involvement in physical activity will form the foundations of understanding how to improve performance from a physiological perspective. Students analyse movement skills and fitness requirements and apply relevant training principles and methods to improve performance at various levels (individual, club and elite). Improvements in performance, in particular fitness, depend on the ability of the individual and/or coach to gain, apply and evaluate knowledge and understanding of training. Students assess fitness and use collected data to justify the selection of fitness tests based on the physiological requirements of an activity, including muscles used, energy systems and fitness components. Students then consider all physiological data, training principles and methods to design a training program. The effectiveness of programs is evaluated according to the needs of the individual and chronic adaptations to training.
In this area of study, students focus on participation, implementation and evaluation of training principles and methods from practical and theoretical perspectives. They consider the ways in which fitness can be improved by applying appropriate training principles and methods when designing and critiquing a training program. Students identify and consider components of an exercise training session, and they record and analyse relevant data that can be used to adjust training. Students explain the chronic adaptations of the cardiovascular, respiratory and muscular systems that improve fitness and enhance performance.
