Explain periodisation of a training year and the role of rest, recovery and overtraining in adaptation

What this dot point is asking

SEAB wants you to explain how a training year is planned in phases (periodisation) and why rest and recovery are essential, including the dangers of overtraining. The central idea is that fitness is built during recovery, not during the session itself, so a smart plan balances hard work with enough rest to let the body adapt.

The answer

Periodisation of a training year

Periodisation means dividing the training year into phases, each with a different focus, so the athlete peaks at the right time.

• Pre-season (preparation): before competition, the athlete builds a base of general fitness and then sport-specific fitness, with a high volume of training.
• Competition (in-season): during the season, the focus shifts to maintaining fitness, sharpening skills and tactics, and peaking for important fixtures, with lower training volume to stay fresh.
• Off-season (transition): after the season, the athlete takes active rest, recovering physically and mentally while keeping light activity to avoid losing too much fitness.

Why recovery matters

The crucial idea is that adaptation happens during recovery. Training stresses the body; rest is when the body repairs the damage, rebuilds tissue and supercompensates, coming back fitter than before. Skip the recovery and the body never adapts: progress stalls and injury risk rises.

Recovery includes sleep, rest days, good nutrition and rehydration, and active recovery such as light exercise that aids the removal of lactic acid.

Overtraining

Overtraining happens when training load is too high and recovery too little for too long. Warning signs include:

• persistent fatigue and heavy legs;
• a raised resting heart rate;
• frequent illness or infection;
• loss of motivation and disturbed sleep;
• a drop in performance despite hard training.

The cure is more rest, not more training.

Examples in context

Example 1. A swimmer tapering for a championship. In the final weeks the coach reduces training volume (a taper) so the swimmer recovers fully and supercompensates, arriving fresh and fast. This is periodisation in action: cutting the load at the right time produces the peak performance.

Example 2. A runner ignoring recovery. Training hard every day with no rest, the runner develops a raised resting heart rate, heavy legs and a string of colds, and their race times slow. The coach diagnoses overtraining and prescribes rest, after which performance recovers, showing that recovery is part of training, not a break from it.

Try this

• Cue. Name the three phases of a training year and the focus of each. (Pre-season: build fitness; competition: maintain and peak; off-season: rest and recover.)

• Cue. Explain the statement "you get fitter during recovery". (Training stresses the body; during rest it repairs and supercompensates, returning fitter than before, so adaptation happens in recovery.)

• Cue. List three signs of overtraining and state the remedy. (Persistent fatigue, raised resting heart rate, frequent illness; the remedy is more rest, not more training.)
