Periodisation without a rigid scheme
What periodisation can achieve, what research says about it and how a season plan with planned-versus-actual comparison stays flexible.
Periodisation means dividing training over weeks and months into sections with different emphases. Classical models prescribe fixed cycles for this. Kiely shows that these models rest more on tradition than on evidence and that individual responses to training vary widely.
What research says
Afonso and colleagues compared meta-analyses: periodised programmes did somewhat better for strength gains in several analyses, but the evidence is limited. Mujika and colleagues recommend planning training, recovery, nutrition and stress outside sport together.
Planning flexibly
A plan is an assumption. Record what was planned and what was actually trained, and adjust the next weeks by disclosed rules: reduce after illness, poor well-being or missed sessions, increase carefully after good weeks.
With the control loop
The tool plans the season for individual, team and extreme sports, compares planned and actual and shows every adjustment rule openly.
Key point: A season plan is a draft: comparing planned and actual and adjusting by clear rules works better than a rigid scheme.
