Understanding key GCSE PE definitions is essential for Paper 2... Show more





Ever wondered why some athletes perform better under pressure whilst others crumble? Arousal explains this - it's your mental and physical state of readiness that ranges from sleepy to absolutely buzzing with energy. Getting this right is crucial for peak performance.
Ability is what you're born with - those natural talents that make learning certain skills easier. Think of it as your sporting potential waiting to be unlocked. Meanwhile, skill is what you actually learn and develop through practice - it's about performing actions with maximum success and minimum wasted effort.
The contract to compete might sound formal, but it's simply the unwritten agreement that all players will follow the rules and give their best effort. Without this mutual respect, sport wouldn't work. Gamesmanship pushes these boundaries - it's bending (but not breaking) rules to gain an advantage, like time-wasting when you're winning.
Quick Tip: Remember that ability is inherited, but skills are learned - this distinction often appears in exam questions!

Etiquette governs how we behave in sport - those unwritten rules like shaking hands after a match or not celebrating excessively when winning. It's about respect and sportsmanship, even though it's not officially enforced.
Aggression in sport comes in two forms. Direct aggression involves actual physical contact with opponents (think rugby tackles), whilst indirect aggression targets objects instead - like smashing a tennis racket in frustration. Hooliganism takes this too far, describing violent, disorderly behaviour by spectators that brings sport into disrepute.
Your drive to succeed comes from two sources. Intrinsic motivation bubbles up from within - you play because you genuinely love it. Extrinsic motivation comes from external rewards like trophies, money, or recognition from others. The best athletes usually combine both types.
Home field advantage is real - familiar surroundings and supportive crowds genuinely boost performance. Meanwhile, deviance describes behaviour that goes against sport's moral values or rules.
Remember: Intrinsic = Internal drive, Extrinsic = External rewards - use this memory trick in exams!

Health isn't just about not being ill - it's complete physical, social and mental wellbeing. Fitness is more specific: your ability to meet the demands of your environment, whether that's climbing stairs or running a marathon. A sedentary lifestyle with little physical activity threatens both.
Commercialisation and sponsorship dominate modern sport. Commercialisation means running sport like a business to make profit, whilst sponsorship involves companies providing support in exchange for advertising opportunities. The media amplifies this through various technologies that reach mass audiences.
Performance-enhancing drugs come in several dangerous forms. Anabolic steroids are artificial male hormones that build muscle but cause serious side effects. Beta blockers calm nerves by controlling heart rate - useful in precision sports like archery but banned in most competitions.
Blood doping and EPO both artificially increase red blood cells, boosting oxygen delivery to muscles. Diuretics remove body fluid to help athletes make weight categories, whilst narcotic analgesics mask pain that should warn athletes of injury.
Health Warning: All these drugs carry serious health risks and are banned in competitive sport - the short-term gains aren't worth the long-term consequences!

Peptide hormones work by stimulating your body's natural hormone production, particularly those that increase red blood cell count and oxygen-carrying capacity. They're essentially tricking your body into producing more of what it already makes naturally.
Stimulants target your central nervous system, ramping up mental alertness and physical energy levels. Think caffeine on steroids - they make athletes feel more awake and energetic, but come with significant health risks and are banned in competition.
These final drug categories complete the picture of how athletes might attempt to gain unfair advantages. However, anti-doping agencies are constantly developing new detection methods, and the health consequences make these substances incredibly dangerous choices.
Exam Focus: Know the specific effects of each drug type - questions often ask you to match drugs to their effects or explain why certain sports might see particular drugs used.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7.
