Fitness Components and Energy Systems Explained

Recap: What We've Learned So Far

Fitness has health-related and skill-related components Cardiovascular endurance helps your heart and lungs Muscular strength and flexibility prevent injuries Balance, coordination, and agility improve performance Understanding fitness helps you make better exercise choices

Fitness Components and Energy Systems Explained

Year 13 Physical Education Understanding the science behind movement and performance

Health-Related Components of Fitness

Cardiorespiratory Endurance - heart, lungs, and blood vessels supplying oxygen during sustained activity Muscular Strength - maximum force a muscle can exert in a single effort Muscular Endurance - ability to exert force repeatedly over extended periods Flexibility - range of motion available at joints Body Composition - relative proportions of fat, muscle, bone, and other tissues

Skill-Related Components of Fitness

Balance - maintaining body position while stationary or moving. Essential in gymnastics and surfing where stability is constantly challenged. Coordination - using different body parts smoothly and efficiently together. Seen in hitting a baseball or dribbling a basketball. Reaction Time - time between stimulus and muscular response. Critical for sprinters responding to the starting gun. Agility - changing direction quickly while maintaining control. Used by soccer players weaving past defenders. Speed - moving the body or body parts swiftly. Important for sprinters and wide receivers in football. Power - maximum force in shortest time (strength + speed). Applied when jumping for a rebound or throwing a javelin.

The Three Energy Systems Timeline

Energy Systems Breakdown

{"left":"ATP-PC System: 0-10 seconds, Uses stored ATP in muscles, Immediate energy, No oxygen required, Examples: weightlifting, shot put\nAnaerobic Glycolysis: 10-180 seconds, Uses stored glycogen, Produces lactic acid, Moderate intensity, Examples: 400m run, basketball","right":"Aerobic System: 180+ seconds, Uses oxygen with fats/carbs, Sustainable energy, No harmful by-products, Examples: marathon, cycling"}

Energy Systems in Sports Analysis

Work in pairs to analyze your favorite sport Identify which energy system(s) are primarily used Consider different positions or phases of the game Prepare to share one example with the class

Training Adaptations and Applications

ATP-PC System Training: Short, explosive efforts with full recovery (e.g., weightlifting, sprint intervals) Anaerobic Training: High-intensity intervals, lactate threshold training Aerobic Training: Continuous moderate exercise, improves oxygen delivery and utilization Understanding energy systems helps optimize training programs Different sports require different energy system development
