Welcome to Physical Training!
In this chapter, we are going to explore how athletes and everyday people improve their bodies to perform better in sports and stay healthy. Think of your body like a high-performance car: to get the best out of it, you need to understand how it works, how to "tune" it through training, and how to keep it from breaking down.
Don't worry if some of the terms seem scientific at first—we'll break everything down into simple steps!
3.1 Health, Fitness, and Exercise
Before we start training, we need to know what we are aiming for. People often use these words to mean the same thing, but in PE, they have specific meanings:
Health: A state of complete emotional, physical, and social well-being, and not merely the absence of disease and infirmity.
Fitness: The ability to meet the demands of the environment (being able to do everyday tasks without getting too tired).
Exercise: Physical activity that maintains or improves health and fitness.
Performance: How well a task is completed.
Analogy: Think of Health as the car being in good repair (no rust, engine works). Fitness is having enough fuel and the right tires for a specific journey. Exercise is the practice laps you take to get ready!
Quick Review: You can be "fit" for one sport but not "healthy" if you have a cold. You can also be "healthy" but not "fit" enough to run a marathon.
3.2 The Components of Fitness
Fitness isn't just one thing. A weightlifter needs a different kind of fitness than a ballerina. Here are the 11 components you need to know:
1. Cardiovascular Fitness (Aerobic Endurance): The ability of the heart and lungs to supply oxygen to the muscles for a long time (e.g., long-distance running).
2. Strength: The maximum force a muscle or muscle group can exert against a resistance.
3. Muscular Endurance: The ability of a muscle to work for a long time without getting tired (e.g., rowing).
4. Flexibility: The range of motion at a joint.
5. Body Composition: The ratio of fat to fat-free mass (muscle, bone, etc.) in the body.
6. Agility: The ability to change direction quickly and under control (e.g., a rugby player dodging a tackle).
7. Balance: Keeping the center of mass over the base of support (e.g., a gymnast on a beam).
8. Coordination: Using two or more body parts together smoothly (e.g., hand-eye coordination in cricket).
9. Power: Strength × Speed. Doing things with force and speed (e.g., a vertical jump).
10. Reaction Time: The time it takes to respond to a stimulus (e.g., the starting gun in a race).
11. Speed: Moving the body or body parts quickly.
How do we measure these? (Fitness Testing)
We use specific tests so we can collect data and compare it to "normative data" (average scores for people your age).
Cardiovascular: Cooper 12-minute test (run or swim) or the Harvard Step Test.
Agility: Illinois Agility Run Test.
Strength: Grip Dynamometer.
Muscular Endurance: One-minute sit-up or press-up test.
Speed: 30m Sprint.
Power: Vertical Jump.
Flexibility: Sit and Reach test.
Key Takeaway: Fitness testing helps athletes see their strengths and weaknesses so they can plan the right training.
3.3 Principles of Training
To get better, you can't just do the same thing every day. You need a plan! Use the FITT principle and the core principles of training:
Individual Needs: Matching training to the person's age, fitness level, and sport.
Specificity: Training for a specific sport or muscle group. (A swimmer shouldn't just practice cycling!)
Progressive Overload: Gradually increasing the amount of work to keep the body adapting.
Overtraining: Training too hard or too much without enough rest.
Reversibility: If you stop training, you lose your fitness. Use it or lose it!
Thresholds of Training: This is how hard you work.
The FITT Principle
Frequency: How often you train.
Intensity: How hard you train.
Time: How long you train for.
Type: The method of training used.
Working out your Training Zones
To know if you are training your heart and lungs (Aerobic) or your power (Anaerobic), we use the Karvonen Formula to find your Maximum Heart Rate (MaxHR):
\( 220 - \text{age} = \text{MaxHR} \)
Aerobic Target Zone: \( 60\% \text{ to } 80\% \text{ of MaxHR} \) (Good for endurance).
Anaerobic Target Zone: \( 80\% \text{ to } 90\% \text{ of MaxHR} \) (Good for speed and power).
Training Methods
Continuous: Working at a steady pace for at least 20 minutes (e.g., jogging).
Fartlek: "Speed play" in Swedish. Changing speeds and terrain.
Circuit: Moving between different stations doing different exercises.
Interval: Periods of hard work followed by periods of rest.
Plyometrics: Explosive movements (like jumping) to improve power.
Weight/Resistance: Using weights to improve strength or muscular endurance.
Key Takeaway: Your training must match your goals. If you want to be a sprinter, use Interval and Plyometric training, not long-distance Continuous runs!
3.4 Long-Term Effects of Exercise
If you train regularly for weeks and months, your body changes. These are called adaptations.
For your muscles and bones:
- Bone density increases (stronger bones).
- Ligaments and tendons get stronger.
- Muscle Hypertrophy: Muscles get bigger and stronger.
For your heart and lungs:
- Resting Heart Rate decreases (your heart is more efficient).
- Stroke Volume increases (more blood per beat).
- Capilliarisation: More tiny blood vessels grow around the muscles to deliver oxygen.
- Varying Lung Capacities: You can take in and use more oxygen.
Did you know? Adaptations don't actually happen while you are lifting weights. They happen while you rest and sleep afterwards! That’s why rest days are vital.
3.5 Optimising Training and Preventing Injury
Safety first! Before starting a program, you should complete a PARQ (Physical Activity Readiness Questionnaire) to make sure you don't have underlying health issues.
How to stay safe:
- Use the right protective clothing (like shin pads in football).
- Check facilities and equipment before you start.
- Follow the rules of the sport.
- Don't overtrain.
Common Injuries
Concussion: Head injury from a blow to the skull.
Fracture: A broken bone.
Dislocation: When a bone is forced out of its joint.
Sprain: A torn or overstretched ligament (bone to bone).
Strain: A "pulled muscle" or tendon (muscle to bone).
Abrasions: Scrapes or "carpet burns" on the skin.
Treatment for minor injuries: Remember R.I.C.E.
Rest, Ice, Compression, Elevation.
Performance-Enhancing Drugs (PEDs)
Some people cheat by using drugs. You need to know these examples:
- Anabolic Steroids: For muscle growth and fast recovery.
- Beta Blockers: To stay calm and steady (used in archery or snooker).
- Stimulants: To increase alertness and reduce tiredness.
Quick Review: PEDs are dangerous and can cause heart disease, liver damage, and even death. They also lead to bans from sport.
3.6 Warm Up and Cool Down
Every session needs a beginning and an end.
Warm Up: Prevents injury and prepares the mind.
Phases: Pulse raiser (light jogging) -> Stretching -> Skill-related drills.
Cool Down: Helps remove lactic acid and prevents muscles from feeling stiff the next day.
Phases: Low-intensity exercise (slow walk) -> Static stretching.
Final Tip: When answering exam questions, always try to link the Training Principle (like Specificity) to a real sport (like a goalkeeper practicing diving catches).
