What this dot point is asking
CCEA wants you to know the main methods of training and the component of fitness each one develops, and to know the principles that make any training programme effective. A method is the practical way you train; a principle is the rule that decides how the training is organised so that it actually improves fitness.
The methods of training
Continuous training is steady, sub-maximal exercise sustained for a long period, such as a 40 minute run; it develops cardiovascular endurance. Interval training alternates high-intensity work with recovery periods; it develops speed and anaerobic endurance. Fartlek (speed play) mixes continuous running with bursts of faster work over varied terrain; it develops both aerobic and anaerobic endurance. Circuit training moves through a series of stations exercising different muscle groups; it can develop strength, muscular endurance or cardiovascular endurance depending on the design. Weight (resistance) training uses resistance to develop strength (high load, few reps), power, or muscular endurance (low load, many reps). Plyometric training uses explosive jumping and bounding to develop power. Flexibility training uses stretching (static, dynamic or proprioceptive neuromuscular facilitation) to develop the range of movement at a joint.
The principles of training
Specificity means a sprinter trains for speed and power, not long slow distance. Progressive overload means raising the training load over time, because the body only adapts when it is stressed beyond its current capacity. Reversibility, sometimes summarised as "use it or lose it", means adaptations are lost during long breaks such as injury. Individual differences means the same programme will not suit everyone, so age, starting fitness and goals must be considered.
The FITT and SPORT formulas
These two acronyms package the principles into a usable checklist. FITT sets the variables you can adjust: Frequency (how often), Intensity (how hard), Time (how long) and Type (the method). SPORT lists the principles to honour: Specificity, Progression, Overload, Reversibility and Tedium (varying training to avoid boredom and keep the performer motivated). Overload is achieved in practice by manipulating the FITT variables.
Examples in context
Example 1. Matching method to goal for a netballer. A netball coach wants to improve a player's explosive jumping for rebounds. Continuous running would be the wrong method because it develops endurance, not power. The coach instead uses plyometric training (box jumps and bounding) for power and adds weight training for leg strength. This shows specificity in action: the method must match the component the sport demands, or the training time is wasted.
Example 2. Reversibility during injury. A footballer who is out for eight weeks with a hamstring injury loses cardiovascular endurance and muscular strength because the training stimulus has been removed, which is the principle of reversibility. On return, the programme cannot simply resume at the pre-injury load; it must restart at a lower load and reapply progressive overload to rebuild fitness safely. This illustrates why reversibility and progressive overload are planned together.

Q2. Explain why specificity is the first principle a coach should consider when planning training. [3 marks]
- Cue. Training must match the components, muscle groups and energy systems the activity uses, or the adaptations will not transfer to performance.
Exam-style practice questions
Practice questions written in the style of CCEA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
CCEA AS 20186 marksDescribe interval training and explain how the principle of progressive overload can be applied to it over a training programme.Show worked answer →
Plan the answer in two halves: describe the method, then apply the principle.
Interval training alternates periods of high-intensity work with periods of rest or low-intensity recovery. For example, a sprinter might run 6 repetitions of 200 metres at near-maximal pace, with a 90 second walk recovery between each. It can develop both speed and anaerobic endurance depending on the work-to-rest ratio.
Progressive overload means gradually increasing the demand on the body so that fitness keeps improving as the body adapts. Applied to interval training, the performer could increase the number of repetitions, increase the running speed, increase the distance of each interval, or shorten the recovery period over the weeks of the programme. Each of these raises the training stress so that adaptation continues.
Markers reward a clear description of work and recovery intervals, plus at least two correct ways to apply progressive overload.
CCEA AS 20224 marksState what each letter of the FITT principle stands for and give one way each could be changed to make a programme harder.Show worked answer →
FITT is a checklist for varying the training load.
Frequency is how often you train, for example training four days a week instead of three. Intensity is how hard you train, for example lifting a heavier weight or running faster. Time is how long each session lasts, for example extending a run from 30 to 40 minutes. Type is the kind of training, for example switching from continuous running to interval running for a different adaptation.
Markers reward the correct expansion of each letter and a valid way to increase the demand for each.
