What this dot point is asking
A training programme only works if it follows certain rules. The SQA wants you to know the principles of training that make a programme effective: specificity, progressive overload, the FITT principle (frequency, intensity, time, type), reversibility, and the need for rest and recovery so the body can adapt.
Specificity and progressive overload
These two principles decide whether training improves the right things.
- Specificity. A sprinter trains speed and power, not just long, slow runs, so the gains transfer to sprinting. Training the wrong system wastes effort.
- Progressive overload. Running a little further or faster each week keeps challenging the body; staying at the same level brings no further gain.
The FITT principle
FITT is the practical way to apply progressive overload.
- Frequency. Train more often, for example three sessions a week rising to four.
- Intensity. Work harder, for example at a higher heart rate or with heavier loads.
- Time. Make each session longer.
- Type. Change to a more demanding method as fitness improves.
Adjusting FITT lets you overload in a controlled, gradual way rather than doing too much too soon.
Reversibility, rest and recovery
These principles protect and lock in your gains.
- Reversibility. A few weeks off through injury or laziness sees fitness fall away, which is why consistency matters.
- Rest and recovery. Planned rest days and sleep let the body repair and adapt, so the next session can be productive.
Examples in context
Example 1. Specificity for a swimmer. A swimmer mostly trains in the pool with strokes and intervals that match racing, rather than long road runs. This keeps the training specific so improvements transfer to their event.
Example 2. Reversibility after injury. A games player out for a month returns noticeably less fit, because reversibility has reduced their cardio-respiratory endurance. They must rebuild gradually rather than expecting to resume at their old level.
Try this
Q1. State what each letter of FITT stands for. [1 mark]
- Cue. Frequency, Intensity, Time, Type.
Q2. Explain why rest and recovery are part of effective training. [1 mark]
- Cue. The body adapts and gets stronger during recovery, so rest allows the gains from training to take effect.

SQA N5 style4 marksExplain how progressive overload and specificity make a training programme effective.Show worked answer →
The command word is explain, so each principle needs to be defined and linked to why it makes the programme work, with two marks per principle.
Progressive overload. This means gradually increasing the demands of training over time, for example running a little further or faster each week. It works because the body only improves when it is made to work harder than it is used to, so without overload there is no further gain.
Specificity. This means the training must match the demands of the activity and the factor being developed. It works because training the right energy system, muscles and skills brings improvements that actually transfer to the performance.
Markers reward each principle defined and linked to why it improves performance, up to four marks.
SQA N5 style4 marksDescribe the FITT principle and how it can be used to make a programme harder over time.Show worked answer →
A 4-mark answer needs each part of FITT described, with a sense of how adjusting them increases the demand.
FITT stands for Frequency (how often you train), Intensity (how hard), Time (how long each session lasts) and Type (the kind of training).
To make a programme harder over time, you can increase frequency from three to four sessions a week, raise intensity by working at a higher heart rate, extend the time of each session, or change the type to a more demanding method.
This applies progressive overload in a controlled way, so the body keeps being challenged and continues to adapt.
Markers reward each FITT letter explained (up to 2) plus how adjusting them overloads the body to keep improving (up to 2), to a total of four.
