Choose the right game
Ask about the session before turning up: its pace, contact rules, breaks, pitch surface and what happens if you need to stop. Walking football or a casual skills session may fit better than a full match. The label over-40s does not tell you how demanding the game will be.
Build towards playing
Before a match, try suitable walking or other manageable activity and see how you recover. Add simple strength work appropriate to your ability. For a first session, agree a shorter stint or a substitute role rather than relying on pride to decide when to stop. Warm up gradually using the session organiser's appropriate routine; old injuries and current pain deserve consideration.
Make the arrangements practical
- Choose footwear suitable for the surface and check the pitch conditions.
- Tell the organiser about limits they need to know, without sharing more personal information than necessary.
- Bring water and make travel home straightforward.
- Leave recovery time before another hard session.
- Judge the session by whether it was enjoyable and manageable, rather than by the quickest bloke on the pitch.
Do not use the game to test worrying symptoms
If you have been inactive, have a medical condition or are uncertain what exertion is appropriate, get individual advice first. Football can be vigorous activity. Stop for concerning symptoms; sudden chest pain, collapse or severe breathing difficulty needs emergency help. A game is not the place to find out whether an unexplained symptom is harmless.
