Principles of Training and Overload

SPORT and FITT are the two rulesets every training programme has to satisfy. SPORT sets out what a good programme must be; FITT is the set of dials you turn to keep it working. Most students can recite the letters and then lose marks when asked what each principle actually does for a performer's fitness, or what happens when the principles are ignored.

Overload + no recovery = injury and overtraining.
SPORT tells you what a good programme must do; FITT tells you how to overload it.

SPORT and FITT: two rulesets for one programme

A training programme has to do two jobs. It has to be right for the activity and the performer, and it has to change as the performer improves. Cambridge splits those jobs into two acronyms: SPORT for the principles of training, and FITT for the principles of overload.

SPORT describes the qualities a programme must have. FITT is how you actually make overload happen — how often, how hard, how long, and what kind of training.

Learn them as a pair. Reciting the letters is worth one or two easy marks; explaining what each one does is where the rest of the marks are.

SPORT: the five principles of training

Each principle is a rule the programme has to obey. Notice that the sporting example always shows the principle in action, not just the definition.

PrincipleWhat it meansFootball example
SpecificityTraining must match the demands of the activity — the muscles, the energy systems and the components of fitness the performer actually usesA goalkeeper trains reaction time and agility, not long-distance running
ProgressionIncreasing the amount of training gradually over time, so the body keeps adaptingA player builds from 20 minutes of training to 35 minutes over a month
OverloadTraining harder than the body is used to, so it adapts and fitness improvesAdding an extra set of squats or an extra set of shuttle runs each week
ReversibilityIf training stops, the adaptations are lost and fitness dropsA player out for six weeks with a knee injury returns with less stamina
TediumTraining must be varied, or the performer becomes bored and loses the motivation to trainMixing small-sided games and circuits into a running session instead of only running
Specificity is the principle examiners ask about most often. "Explain how a performer would apply specificity" is not asking for a definition — it is asking you to name the muscles, the energy system or the components of fitness the activity needs.

Overload: the FITT principles

Overload only works if you can adjust it, and FITT is how you adjust it: four variables you change to make training harder in a controlled way.

Change one variable at a time. Increase all four at once and the performer is not progressing, they are heading for overtraining.

LetterPrincipleHow the performer changes it
FFrequencyTraining more often — three sessions a week instead of two
IIntensityTraining harder — heavier weights, a faster pace, a higher percentage of maximal heart rate
TTimeTraining for longer — a longer run, longer work periods, more repetitions
TType (method of training)Changing the method — continuous, weight, fartlek, plyometric, circuit, HIIT or high-altitude training
Note the second T. In FITT it stands for the type of training — the method being used. It is not time written twice.

Progression has to be gradual

Progression and overload look like the same thing, and students lose marks by treating them as one. Overload is training harder than the body is used to. Progression is the rule that the extra work is added a little at a time, once the body has adapted to the last increase.

A performer who jumps the load up too far does not get fit faster. The muscles, tendons and joints have not adapted to the new demand, so the result is injury and lost training time.

Small steps also protect the performer's confidence, because each new target is achievable. That is why progression and motivation go together.

Reversibility and tedium

Reversibility is 'use it or lose it'. The adaptations made in training are not permanent — stop training and they fade. Endurance is usually the first thing a performer notices going, which is why a performer returning from injury cannot simply pick up where they left off.

Tedium is boredom, and it is a training principle because a bored performer trains less. Variety in the method, the venue and the activities is what keeps a performer working hard enough to overload in the first place.

The dangers of overtraining

Overtraining is doing more training than the body can recover from. It is not the same as working hard: a well-planned programme is hard work with recovery built in.

  • Overuse injury — muscles, tendons and joints damaged by repeated stress without recovery, such as a stress fracture in a runner's foot
  • Constant fatigue — the performer is still tired at the start of the next session, so the quality of training drops
  • A drop in performance despite training more, which is frustrating and confusing for the performer
  • Illness, because the body's defences are run down by continual hard training without enough rest
  • Loss of motivation and enjoyment, which can lead the performer to stop training altogether — and then reversibility sets in
  • Persistent muscle soreness and stiffness, and disturbed sleep
Rest is part of the programme, not a break from it. Recovery days are when the body actually makes the adaptations the hard sessions were asking for.

Applying SPORT and FITT: a netball player

Take a netball player who wants to improve. Specificity says she must train the stop-start demands of the game — short bursts of running and jumping, not long slow runs. FITT gives her the dials: add a third session each week (frequency), work closer to her maximum in the interval work (intensity), extend the session from 45 to 60 minutes (time), and use a mix of circuit and plyometric work (type), because netball needs muscular endurance around the court and power for the jump.

Progression means each change is small and only made once she has adapted to the last one. Reversibility is the warning: stop in the off-season and the gains fade. Tedium is why her coach varies the sessions instead of repeating the same circuit every week.

Key terms you must be able to define

Specificity
Training must be matched to the demands of the activity — the muscles, energy systems and components of fitness the performer uses.
Progression
Increasing the amount of training gradually over time, so the body keeps adapting without being injured.
Overload
Training harder than the body is used to, so that the body adapts and fitness improves.
Reversibility
If training stops, the adaptations are lost and fitness declines.
Tedium
Boredom caused by training that never changes; it reduces motivation, so the training aim is no longer met.
Frequency
How often the performer trains — the number of sessions per week or month.
Intensity
How hard the performer works in a session, e.g. the weight lifted or the percentage of maximal heart rate.
Time
How long each training session lasts, or the length of each work period within it.
Type (method of training)
The method of training used, e.g. continuous, weight, fartlek, plyometric, circuit, HIIT or high-altitude training.
Overtraining
Training beyond what the body can recover from, leading to fatigue, injury and a drop in performance.

Applied to your sport

Cambridge requires you to apply this knowledge to physical activities. Use these as models, then write your own for the sport you play.

Association Football

A defender needs agility, reaction time and muscular endurance, so pre-season training is a mix of sprint drills, small-sided games and circuit work — that is specificity. The number of repetitions and the length of each drill go up week by week, which is progression and overload.

Competitive Swimming

A competitive swimmer progresses from 1,500 m of steady swimming per session to 2,500 m over a ten-week block. Increasing the distance is overload applied through the time and frequency variables of FITT.

Basketball

A player who breaks a wrist and cannot train for six weeks finds their stamina and their shooting accuracy have both dropped when they return. That is reversibility — the fitness must be rebuilt gradually rather than starting where it was left off.

Cross-Country Running

A cross-country runner who repeats the same 10 km loop every session becomes bored and stops pushing the pace. Fartlek work on different terrain varies the training and removes the tedium.

Q1What does SPORT stand for?
Specificity, Progression, Overload, Reversibility, Tedium.
Q2Define specificity.
Training must match the demands of the activity — the muscles, energy systems and components of fitness the performer uses.
Q3Define overload.
Training harder than the body is used to, so the body adapts and fitness improves.
Q4What does the second T in FITT stand for?
Type — the method of training used, e.g. circuit, fartlek or plyometric training.
Q5Give a sporting example of reversibility.
A performer out with an injury for six weeks returns with lower stamina and must rebuild their training gradually.
Q6What is tedium, and why does it matter in training?
Boredom from training that never changes. A bored performer loses motivation and trains less, so the fitness gains stop.
Q7State four dangers of overtraining.
Overuse injury; constant fatigue; a drop in performance despite training more; illness or loss of motivation.
Q8How is overload different from progression?
Overload is training harder than the body is used to. Progression is increasing the load gradually over time so the body keeps adapting.
Q9Which FITT variable is changed by making a session longer?
Time.
Q10Why should progression be gradual?
So the muscles, tendons and joints have time to adapt. Too large an increase causes injury and lost training time.

Exam-style questions

7 questions, 18 marks. Write your answer, then reveal the mark scheme and tick each point you actually made. Answering honestly here is what makes the rest of the site useful.

StateAO11 mark
State what the letter O stands for in the SPORT principles of training.

Mark scheme — tick each point you actually made

Examiner tip: One mark, one letter. Do not expand it — you are not asked to explain it here.
IdentifyAO12 marks
Identify two of the FITT principles of overload.

Mark scheme — tick each point you actually made

Any 2 of these score full marks. The examiner only needs 2 distinct points - pick the ones you actually made.
Examiner tip: Any two of the four score. Naming a SPORT principle such as specificity scores nothing here — read which acronym the question asks for.
DescribeAO12 marks
Describe how tedium can be avoided in a training programme.

Mark scheme — tick each point you actually made

Examiner tip: The command word is describe, so give the technique plus what it does — it stops the performer getting bored and losing motivation.
ExplainAO23 marks
Explain how a badminton player would apply specificity to their training programme.

Mark scheme — tick each point you actually made

Examiner tip: Every point names something the activity demands and then shows the training matching it. Three demands, three marks.
ExplainAO23 marks
Explain what is meant by reversibility and how it affects a performer who is injured and cannot train.

Mark scheme — tick each point you actually made

Examiner tip: Definition first, then the consequence for this performer. A definition alone caps you at one mark.
EvaluateAO25 marks
A young performer has been training hard for several months with no rest days. Evaluate the risks of their training programme.

Mark scheme — tick each point you actually made

Examiner tip: An evaluate question wants the risks plus a judgement. Make your last point the solution — rest days and a reduced load — so the answer ends with a decision.
ExplainAO22 marks
Explain why a performer should use progression rather than increasing the training load as quickly as possible.

Mark scheme — tick each point you actually made

Examiner tip: The question contains a comparison, so both sides need to appear: gradual progression and the consequence of going too fast.

Exam technique for this topic

  • If the command word is state or identify, the letters are enough. If it is explain, every point needs a consequence for the performer — what the principle does to their fitness or their performance.
  • Use the letters as a checklist. A 5-mark question on applying the principles of training means five principles, each with a line explaining what it means for this performer.
  • Do not write overload and progression as though they were the same thing. Overload is training harder than usual; progression is increasing the load gradually over time.
  • Pick one activity from the syllabus list and stay with it for the whole answer. Specificity is far easier to explain for a sport you actually know.

Why students lose marks here

A student wroteOverload means you must always train to exhaustion.
Why it loses marksExhaustion is not overload, it is overtraining. Overload means working harder than the body is used to and then allowing it to recover so the body adapts.
The answer that scoresOverload means training at a level above what the performer is used to, so the body adapts and fitness improves. The extra work is followed by rest, which is when the adaptation happens. Training to exhaustion every session is overtraining and leads to injury and fatigue.
A student wroteReversibility means you can reverse the effects of an injury by training.
Why it loses marksThe word looks as though it is about coming back from injury, but it means the opposite. Reversibility is the loss of training adaptations when training stops.
The answer that scoresReversibility means that if training stops, the adaptations are lost and fitness falls. A performer who cannot train for six weeks loses cardiovascular endurance and some muscular strength, and has to rebuild the training load gradually when they return.
A student wroteTedium is the tiredness you feel after a hard session.
Why it loses marksTedium is boredom, not fatigue. Fatigue is a physical effect of training; tedium is the psychological problem of training becoming monotonous.
The answer that scoresTedium is boredom caused by training that never changes. It matters because a bored performer loses motivation and reduces their training, so the training aim is no longer met. Varying the training method and the venue reduces tedium.
A student wroteIn FITT, the two T's both stand for time.
Why it loses marksThe second T is the type of training — the method used, such as continuous, fartlek, circuit, plyometric or weight training.
The answer that scoresF = frequency (how often the performer trains), I = intensity (how hard), T = time (how long), T = type (the method of training used).
