Exercise physiology, training and performance

Exercise physiology, training and performance is a core component of the WJEC A-Level Physical Education specification, focusing on the acute and chronic physiological responses of the body to exercise and training. This topic explores how the cardiovascular, respiratory, muscular, and energy systems adapt to different types of physical activity, and how these adaptations can be optimised through specific training methods to enhance performance. Understanding these principles is essential for analysing and improving athletic performance, as well as for designing effective training programmes tailored to individual needs.

The topic is divided into key areas: energy systems (ATP-PC, anaerobic glycolysis, and aerobic system), cardiovascular and respiratory responses to exercise, the effects of training on these systems (e.g., cardiac hypertrophy, increased stroke volume, improved oxygen delivery), and the application of training principles such as specificity, overload, progression, and reversibility. Students also learn about different training methods (continuous, interval, Fartlek, circuit, weight, plyometric, and flexibility training) and how to apply them to improve components of fitness like strength, endurance, speed, and flexibility.

Mastering this topic is crucial for success in the WJEC A-Level exam, as it appears in both the written paper and the non-exam assessment (NEA) where students analyse and evaluate their own or others' performance. It also provides a foundation for further study in sports science, physiotherapy, or coaching. By understanding the science behind training, students can make informed decisions about exercise prescription and performance enhancement, linking theory to real-world sporting contexts.
