What are the different components of fitness, and why does each sport need a different mix?
The components of physical fitness (cardiovascular endurance, muscular endurance, strength, speed, power, flexibility, agility, balance, coordination and reaction time), their definitions, and their importance to performance in different sports.
A focused answer to OCR GCSE PE Component 01 on the components of fitness: the definitions of cardiovascular endurance, muscular endurance, strength, speed, power, flexibility, agility, balance, coordination and reaction time, and how each is important to performance in named sports.

What this dot point is asking
OCR wants you to define each component of fitness and explain why different sports need different components, applying them to named performers.
Health-related components of fitness
Skill-related components of fitness
Matching components to sport
The skill of this topic is choosing the right component for the demand. A weightlifter relies on strength for a one-rep maximum lift. A 100 m sprinter relies on speed and power. A boxer relies on muscular endurance to keep punching through twelve rounds and reaction time to slip a punch. A gymnast on the beam relies on balance and flexibility. A footballer relies on a blend of agility, speed, power and cardiovascular endurance, which is why their training is so varied.
Why the components matter
Knowing the components lets a performer choose the right fitness tests (the next topic) and the right training methods. A coach first identifies which components the sport demands, then tests the athlete on those components and designs training to improve them, which is the basis of a fitness programme (linking to the principles of training).
Exam-style practice questions
Practice questions written in the style of OCR exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
OCR 20184 marksDefine power and agility, and give a sporting example where each is the most important component of fitness.Show worked answer →
A Component 01 item testing definitions and application. Award one mark for each definition and one for each linked example.
Power is the combination of strength and speed (strength multiplied by speed), the ability to produce a large force quickly. Example: a sprinter driving out of the blocks, or a high jumper at take-off.
Agility is the ability to change direction quickly while keeping control of the body. Example: a netball player dodging a defender, or a rugby player side-stepping a tackle.
Markers want a precise definition plus a relevant sport where that component is decisive, not just any sport.
OCR 20213 marksExplain why cardiovascular endurance is the most important component of fitness for a marathon runner.Show worked answer →
A 3-mark application question.
Award marks for: cardiovascular endurance is the ability of the heart and lungs to supply oxygen to the working muscles over a long period. A marathon is a long, continuous event lasting more than two hours.
The runner relies on aerobic respiration to keep producing energy for the whole distance, so a high cardiovascular endurance lets them sustain a fast pace without fatiguing early. Without it they would slow down or stop as the muscles ran short of oxygen.
Markers reward the definition, the demand of the marathon, and the clear link between the two.
