Principles of Training — SPORT and FITT

This lesson covers the principles of training that underpin all effective training programmes. The AQA GCSE PE specification (3.1.3) requires you to know and apply two acronyms: SPORT (the principles of training) and FITT (how to apply those principles). Understanding these principles ensures that training is effective, safe, and tailored to the individual.

The SPORT Principles

The acronym SPORT stands for:

• S — Specificity
• P — Progressive Overload
• O — Overtraining (sometimes listed separately as a risk to avoid)
• R — Reversibility
• T — Tedium

Note: Some textbooks use the acronym SPORRT or SPOR with variations. The AQA specification requires Specificity, Progressive Overload, Overtraining, Reversibility, and Tedium (variation/avoiding boredom).

Specificity

Specificity means that training must be relevant to the sport, activity, or individual needs of the performer. Training should target:

• The muscles used in the activity (e.g., a rower should train the back, legs, and arms — not just one muscle group).
• The energy system used (e.g., a marathon runner should train aerobically, while a sprinter should train anaerobically).
• The components of fitness most important for the sport (e.g., a gymnast should focus on flexibility, balance, and strength).
• The movements and skills required (e.g., a swimmer should train in water, not just on a rowing machine).

Example: A 100 m sprinter would use sprint training and plyometrics to develop speed and power, rather than long-distance running which develops cardiovascular endurance.

Progressive Overload

Progressive overload means gradually increasing the demands placed on the body over time. The body adapts to the current training load, so to continue improving, the load must be increased. If the load stays the same, the body plateaus and no further improvement occurs.

Progressive overload can be achieved by:

• Increasing the frequency of training sessions.
• Increasing the intensity (e.g., running faster, lifting heavier weights).
• Increasing the time/duration of training sessions.
• Increasing the complexity or difficulty of exercises.

Example: A weight trainer might increase the weight lifted by 2.5 kg every two weeks, or add an extra set to their routine.

Exam Tip: Progressive overload must be gradual. Increasing the load too quickly risks overtraining and injury. If asked about progressive overload, always mention that increases should be small and manageable.

Overtraining

Overtraining occurs when a performer trains too much without allowing adequate rest and recovery. It is not a principle to follow — it is a risk to avoid.

Signs of overtraining include:

• Persistent fatigue and lack of energy
• Decreased performance despite increased training
• Increased susceptibility to illness and injury
• Difficulty sleeping
• Loss of motivation and increased irritability
• Muscle soreness that does not go away

To avoid overtraining:

• Include rest days in the training programme.
• Alternate between hard and easy training sessions.
• Ensure adequate nutrition, hydration, and sleep.
• Monitor for signs of overtraining and adjust the programme accordingly.

Reversibility

Reversibility means that any fitness gains made through training will be lost if training stops. The effects of training are reversed — fitness levels return to their pre-training state. This is sometimes described as "use it or lose it."

Key points about reversibility:

• It takes much longer to gain fitness than to lose it.
• Aerobic fitness can begin to decline after just 1–2 weeks without training.
• Muscular strength declines more slowly but will still be lost over time.
• Reversibility can occur due to injury, illness, off-season breaks, or simply stopping training.
• To minimise reversibility, athletes should maintain at least a reduced training programme during off-seasons or injury recovery.

Example: A swimmer who takes 4 weeks off training due to illness will find that their cardiovascular endurance has decreased, their stroke rate has slowed, and their race times have worsened.

Tedium (Variety)

Tedium refers to boredom caused by repetitive training. If a performer does the same training routine every session, they will become bored, lose motivation, and may stop training altogether.

To avoid tedium:

• Vary the training methods used (e.g., alternate between continuous training, fartlek training, and circuit training).
• Change the training environment (e.g., train outdoors instead of in a gym).
• Include different exercises within the same session.
• Use music, training partners, or competitive elements to maintain interest.
• Set new targets and goals regularly.
• Use cross-training (participating in different sports or activities to train different components of fitness).

Example: A long-distance runner could alternate between road running, trail running, fartlek sessions, and swimming to avoid the tedium of running the same route every day.

The FITT Principle

The FITT principle provides a framework for applying the principles of training. It stands for:
