GCSE PE Paper 1: The Human Body and Movement

1. Applied Anatomy and Physiology

The Musculoskeletal System

• Functions of the skeleton:

  • Support: Provides a framework for the body.

  • Protection: Shields vital organs (e.g., skull protects the brain).

  • Movement: Works with muscles to facilitate movement.

  • Blood Cell Production: Creates red and white blood cells in the bone marrow.

  • Mineral Storage: Stores minerals like calcium and phosphorus.

• Bone types:

  • Long bones: (e.g., femur) crucial for movement.

  • Short bones: (e.g., carpals) provide stability and support.

  • Flat bones: (e.g., sternum) protect internal organs.

  • Irregular bones: (e.g., vertebrae) support the body and protect the spinal cord.

• Joints:

  • Synovial joints: allow for smooth movement, lubricated by synovial fluid.

  • Hinge joints: (e.g., knee) allow movement in one direction.

  • Ball-and-socket joints: (e.g., shoulder) facilitate circular motion.

• Muscles:

  • Voluntary (skeletal): control movements consciously.

  • Involuntary (smooth): work automatically in organs.

  • Cardiac: found in the heart, responsible for pumping blood.

• Antagonistic muscle pairs: E.g., biceps and triceps work together during flexion (bicep curl) and extension.

• Movement types:

  • Flexion: Decrease the angle between two body parts.

  • Extension: Increase the angle.

  • Abduction: Move limb away from the body.

  • Adduction: Move limb toward the body.

  • Rotation: Movement around an axis.

  • Circumduction: Move in a circular motion.

The Cardiovascular System

• Structure of the heart:

  • Atria: Upper chambers that receive blood.

  • Ventricles: Lower chambers that pump blood out.

  • Valves: Ensure one-way flow of blood.

• Blood vessels:

  • Arteries: Carry oxygenated blood away from the heart.

  • Veins: Return deoxygenated blood to the heart.

  • Capillaries: Exchange nutrients and waste between blood and tissues.

• Blood components:

  • Red blood cells: transport oxygen.

  • White blood cells: fight infection.

  • Plasma: liquid component carrying nutrients, hormones, and waste.

  • Platelets: aid in blood clotting.

• Gaseous exchange:

  • Oxygen enters blood at alveoli; carbon dioxide exits via diffusion.

• Cardiac output: Q = Heart Rate × Stroke Volume (amount of blood pumped per beat).

The Respiratory System

• Pathway of air:

  • Nose → trachea → bronchi → bronchioles → alveoli: Air travels to where oxygen is exchanged for carbon dioxide.

• Lung volumes:

  • Tidal volume: volume of air inhaled/exhaled at rest.

  • Vital capacity: maximum amount of air exhaled after maximum inhalation.

  • Residual volume: air remaining in lungs post-exhalation.

• Breathing mechanics:

  • Diaphragm contracts: during inhalation, increasing lung volume.

  • Diaphragm relaxes: during exhalation, decreasing lung volume.

• Aerobic respiration:

  • Involves oxygen, sustained activity, e.g., marathon running.

• Anaerobic respiration:

  • Occurs without oxygen, produces lactic acid, e.g., sprinting.

2. Movement Analysis

• Levers:

  • First-class lever: Fulcrum in middle (e.g., neck).

  • Second-class lever: Load in middle (e.g., standing on tiptoes).

  • Third-class lever: Effort in middle (e.g., bicep curl).

• Planes of Movement:

  • Sagittal: Divides body into left/right (e.g., running).

  • Frontal: Divides body into front/back (e.g., cartwheel).

  • Transverse: Divides body into top/bottom (e.g., spinning).

3. Physical Training

Fitness Components

• Health-related:

  • Cardiovascular endurance: ability to sustain aerobic exercise.

  • Muscular strength: maximum force exerted by a muscle/group.

  • Muscular endurance: ability of a muscle to sustain repeated contractions.

  • Flexibility: range of motion around joints.

  • Body composition: ratio of fat to lean mass in the body.

• Skill-related:

  • Agility: ability to change direction quickly.

  • Balance: ability to maintain stability.

  • Coordination: ability to use different body parts together effectively.

  • Power: ability to exert maximum force in a short time.

  • Reaction time: the time taken to respond to a stimulus.

  • Speed: ability to move quickly.

Principles of Training

• SPORT:

  • Specificity: Training should be relevant to the sport.

  • Progressive Overload: Gradually increasing training demands.

  • Reversibility: Fitness gains are lost when training stops.

  • Tedium: Avoiding boredom in training.

• FITT:

  • Frequency: How often you train.

  • Intensity: How hard you train.

  • Time: Duration of training.

  • Type: Kind of training done.

Methods of Training

• Continuous: Steady, long-duration exercise.

• Interval: Alternating high and low-intensity efforts.

• Circuit: Series of exercises performed in succession.

• Weight: Training with resistance to build muscle strength.

• Fartlek: Combining different speeds throughout run or session.

• Plyometric: Exercises that exert maximal force in short intervals.

GCSE PE Paper 2: Socio-Cultural Issues and Well-Being

1. Sports Psychology

Skill Classification

• Skill continuum: Movement can range from basic to complex, open to closed and self-paced to externally paced and gross to fine.

• Goal Setting (SMART Goals):

  • Specific: Clear and precise goals (e.g., improve serve in tennis).

  • Measurable: Ability to track progress (e.g., serve accuracy).

  • Achievable: Set within the athlete's capability.

  • Realistic: Practical, considering available resources.

  • Time-bound: Goals should aim for completion within a set timeframe.

Mental Preparation Techniques

• Visualisation: Mental imagery of successful performance.

• Mental rehearsal: Practicing skills mentally without physical movement.

• Positive self-talk: Utilizing encouraging language to boost morale.

• Selective attention: Concentrating on relevant cues while ignoring distractions.

2. Socio-Cultural Influences

Participation Factors

• Personal: Age, gender, disability, and ethnicity can all affect participation levels.

• Socio-economic: Access to facilities and financial capabilities influence the ability to participate in sports.

• Cultural: Social norms, role models, and parental involvement shape attitudes towards sport.

Commercialisation of Sport

• Media influence: Sponsorships, broadcasting, and promotion are driven by media access.

• Advantages: Offers financial support, raises participation levels, and provides global outreach.

• Disadvantages: Over-commercialisation can lead to increased pressure on athletes and a focus on elite sports rather than grassroots initiatives.

Ethics and Deviance in Sport

• Sportsmanship: Conducting oneself with fairness and respect for rules.

• Gamesmanship: Using provocation or unfair tactics to win (e.g., time-wasting).

• Deviance: Activities that break rules, including drug use or match-fixing.

• Performance-enhancing drugs (PEDs): Substances like steroids and stimulants taken to improve performance and their respective health implications.

3. Health, Fitness, and Well-Being

Physical, Emotional, and Social Well-Being

• Physical: Benefits include illness prevention and enhanced energy levels.

• Emotional: Physical activity can elevate self-esteem and alleviate stress.

• Social: Promotes connection, reduces feelings of loneliness, and builds community.

Balanced Diet

• Macronutrients: Provision and energy source from carbohydrates, proteins, and fats.

• Micronutrients: Essential vitamins and minerals that support bodily functions.

• Hydration: Importance of water for optimum cognitive and physical performance.

Lifestyle Choices

• Sedentary behavior: Associated risks include obesity, diabetes, and heart disease.

• Smoking and alcohol: Negative influences on both fitness levels and overall health.

• Positive lifestyle factors: These include regular exercise, a nutritious diet, and proper sleep routines to enhance well-being.

4. Data Analysis

• Interpreting Graphs and Charts:

  • Identify trends, compare groups (e.g., gender differences in sport), and explain cause-and-effect dynamics.

• Use of Data in Sport:

  • Leverage data to measure athletic performance, set actionable goals, and track participation trends effectively.
