Energy Systems & Training
This lesson introduces the body's energy systems and how they support movement and performance. It covers ATP resynthesis, anaerobic and aerobic pathways, training design with FITT, nutrition for energy efficiency, immediate physiological responses, and ethical considerations in fitness testing.
Learning objectives
- Describe how ATP is resynthesized by the ATP-PCr, glycolytic, and aerobic systems.
- Explain how exercise intensity and duration influence energy system dominance and fatigue.
- Compare aerobic and anaerobic training approaches and their application to sport demands.
- Apply the FITT principle to outline a training plan.
- Identify macronutrient, micronutrient, and hydration considerations for energy efficiency.
- Explain immediate physiological responses to exercise.
- Discuss purpose, outcomes, and ethical considerations in fitness testing.
