PE14: Components of Fitness
All 10 components of fitness: definitions, sporting examples and which sports require which components.
📋 Overview of the 10 Components
Key Fact: There are 10 components of fitness that you need to know for GCSE PE. They are divided into health-related and skill-related components.
Health-related components (5) - these contribute to overall health and well-being:
- Cardiovascular endurance
- Muscular endurance
- Flexibility
- Strength
- Body composition
Skill-related components (5) - these are needed for successful performance in sport:
- Agility
- Balance
- Coordination
- Power
- Reaction time
- Speed
Note: Some exam boards classify power and speed as health-related. For AQA, there are 10 components total. The key is knowing all definitions and examples.
❤️ 1. Cardiovascular Endurance
Definition: The ability of the heart, lungs and blood vessels to deliver oxygen to working muscles over a prolonged period of time.
- Essential for sustained, whole-body activities lasting more than a few minutes
- Involves the aerobic energy system
- Determined by the efficiency of the heart, lungs and circulatory system
Sporting Examples
Marathon running (26.2 miles), long-distance cycling (Tour de France stages of 100+ miles), rowing (2000m race lasting ~6 minutes), cross-country skiing, triathlon.
🔄 2. Muscular Endurance
Definition: The ability of a muscle or group of muscles to sustain repeated contractions, or to continue applying force against a fixed object, over a period of time.
- Different from cardiovascular endurance - this is about the muscle itself, not the heart and lungs
- Important for activities requiring repeated muscle actions without rest
Sporting Examples
Rowing (repeated stroke cycles over 2000m), cycling (repeated leg contractions for hours), holding a plank position (sustained abdominal contraction), press-ups (repeated push-up repetitions), gymnastics holds (sustained muscle contraction on rings or bars).
🤸 3. Flexibility
Definition: The range of movement possible at a joint.
- Determined by the structure of the joint, the length and elasticity of ligaments and tendons, and muscle tone
- Some joints naturally have more flexibility than others (ball-and-socket vs hinge)
- Can be improved through stretching exercises
Sporting Examples
Gymnastics (splits, backbends, high kicks), diving (pike position), yoga (various poses), martial arts (high kicks in taekwondo), hurdles (stretching the lead leg over the hurdle).
🏋️ 4. Strength
Definition: The maximum force a muscle or group of muscles can exert in a single maximal contraction.
- Also called maximal strength or absolute strength
- Measured as the heaviest weight that can be lifted once (1RM - one rep max)
- Different from power - strength does not involve speed
Sporting Examples
Weightlifting (clean and jerk, snatch), powerlifting (squat, bench press, deadlift), rugby scrummaging (pushing against the opposition pack), wrestling (holding and controlling an opponent).
⚡ 5. Power
Definition: The ability to exert a maximal force in the shortest possible time. It is a combination of strength and speed.
Power = Strength × Speed
Power is the rate of doing work. It is not just about being strong - the force must be applied QUICKLY.
Power is the rate of doing work. It is not just about being strong - the force must be applied QUICKLY.
- Power requires both high force production AND high speed
- Essential for explosive movements in sport
- Trained through plyometric exercises and explosive weight training
Sporting Examples
Vertical jump in basketball (jumping for a rebound), sprint start in athletics (explosive drive from blocks), long jump (take-off), shot put (explosive release), volleyball spike (hitting the ball down forcefully and quickly).
🏃 6. Speed
Definition: The maximum rate at which an individual can cover a distance or perform a movement.
- Measured as distance covered per unit of time (e.g. metres per second)
- Determined by muscle fibre type, technique and reaction time
- Essential for sprint events and quick movements in team sports
Sporting Examples
100m sprint, 50m freestyle swimming sprint, cycling track sprint, sprinting to score a try in rugby, a tennis player rushing the net.
🔀 7. Agility
Definition: The ability to change direction quickly and precisely while maintaining balance and control.
- Requires a combination of speed, balance, coordination and power
- Essential in team sports and racket sports where rapid changes of direction are needed
- Tested using the Illinois Agility Run
Sporting Examples
Football (changing direction to dribble past a defender), netball (pivoting and dodging), basketball (crossover dribble and change of direction), tennis (moving to reach a wide shot then recovering to centre court), badminton (rapid direction changes to cover the court).
⚖️ 8. Balance
Definition: The ability to maintain the body's centre of mass above the base of support, whether stationary (static balance) or moving (dynamic balance).
- Static balance: Maintaining a still position (e.g. handstand, headstand in gymnastics)
- Dynamic balance: Maintaining balance while moving (e.g. running along a beam, staying upright while being tackled)
Sporting Examples
Gymnastics (balance beam routine - both static holds and dynamic movement), ice skating (maintaining position on one foot), rugby (staying on feet during contact), skiing (maintaining balance on varied terrain).
🎯 9. Coordination
Definition: The ability to use two or more body parts together smoothly and efficiently.
- Often involves hand-eye coordination or foot-eye coordination
- Essential for skills requiring precise timing of movements
- Can be improved through practice and repetition
Sporting Examples
Cricket batting (hand-eye coordination to hit the ball), tennis (hand-eye coordination for racket-ball contact), football (foot-eye coordination for dribbling and passing), juggling (hand-eye coordination), rhythmic gymnastics (whole-body coordination with apparatus).
⏱️ 10. Reaction Time
Definition: The time taken to initiate a response to a stimulus. It is the gap between the presentation of a stimulus and the start of the movement.
- Measured in milliseconds
- A simple reaction time (one stimulus, one response) is typically 0.15-0.20 seconds
- Choice reaction time (multiple possible stimuli/responses) is longer
- Crucial in sports requiring quick responses
Sporting Examples
Sprint start in athletics (reacting to the gun - a simple reaction time), goalkeeper saving a penalty (reacting to the ball direction - a choice reaction time), table tennis (reacting to the opponent's shot), boxing (reacting to an incoming punch), swimming start (reacting to the beep).

✅ Answers
- Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to working muscles over a prolonged period. Example: marathon running, where the athlete must sustain aerobic exercise for over 26 miles.
- Strength is the maximum force a muscle can exert in a single maximal contraction. Power is the ability to exert a maximal force in the shortest possible time (strength × speed). Strength involves maximum force regardless of speed; power requires force to be applied QUICKLY.
- Agility is the ability to change direction quickly and precisely while maintaining balance and control. Examples: a footballer dribbling past a defender with quick changes of direction; a tennis player changing direction to reach a wide shot.
- Power = Strength × Speed.
- Static balance is maintaining the body's centre of mass above the base of support while stationary (e.g. a gymnast holding a handstand on the beam). Dynamic balance is maintaining the body's centre of mass above the base of support while moving (e.g. a rugby player staying on their feet while being tackled).
- Reaction time is the time taken to initiate a response to a stimulus. For a sprinter, it is the time between hearing the starting gun and beginning to push off the blocks. A faster reaction time means the sprinter gets out of the blocks sooner, giving them an advantage in a race decided by hundredths of a second.
🎯 Exam Tips
- Learn ALL 10 definitions word-for-word - this is the most tested topic in PE
- Always link a component to a sporting example - don't just define it
- Power = Strength × Speed is a guaranteed formula question
- Know the difference between muscular endurance (repeated contractions over time) and strength (single maximal force)
- Agility involves CHANGING DIRECTION - don't confuse it with speed (moving in a straight line)
- Coordination = using two or more body parts together smoothly

⚠️ Common Errors
Watch Out!
Students often think fitness and health are the same thing. Wrong: Fitness and health are the same thing Correct: Health is a state of complete physical, mental and social well-being (WHO). Fitness is the ability to meet the demands of the environment. You can be fit but unhealthy (e.g. a marathon runner with flu).
Students often think static stretching is the best warm-up. Wrong: Static stretching is the best warm-up Correct: Current evidence suggests dynamic stretching is more effective in warm-ups as it mimics sporting movements. Static stretching may actually reduce power output if held too long before activity.
Students often think no pain, no gain is a good training principle. Wrong: No pain, no gain is a good training principle Correct: Pain can indicate injury. Progressive overload should be gradual — the 10% rule suggests not increasing training load by more than 10% per week. Ignoring pain leads to overuse injuries.

📊 AO Deep Dive
Assessment Objective Analysis
GCSE PE tests four AOs: AO1 (Knowledge, 30%) — recall facts about Components of Fitness including definitions, classifications and specific examples; AO2 (Application, 30%) — apply knowledge to sporting contexts and training scenarios; AO3 (Analysis and Evaluation, 25%) — analyse data (graphs, tables), evaluate training methods or strategies, and justify recommendations; AO4 (Practical, 15%) — demonstrate relevant skills. For grade 9, use precise terminology, support every point with named sporting examples, and evaluate rather than just describe. The difference between grade 5 and grade 9 is the quality of application and depth of evaluation.
