After an injury, it is advisable to rest the affected area for a few days to allow it to heal. Without it, continual strain is placed on the area, which can lead to increased knee swelling, pain, and in some cases further damage. There is also a risk of the area not healing properly if it is not allowed time to recover.
But how much is appropriate? Obviously it will depend on the injury, but usually a few days is about right and no longer than a week.
By rest I mean avoiding any activities that
increase your pain. Avoid putting too much weight through it or
stretching it too much. If it hurts, that's often your body's way of saying you are overdoing it. But that doesn't mean you should take to your bed!
YES! It is REALLY important to get moving again after a few days otherwise the muscles start to weaken and the joint stiffens. As things are healing, the right stresses and strains need to be put through the area to help it heal properly.
If a muscle isn't being used at all, it loses 3-5% of its strength every day. Therefore in 3-5 weeks a muscle loses half its strength. You may not initially realise that the area is getting weak as you tend to lose endurance strength first, how long the muscle can keep working for, before instantaneous strength, how strong the muscle is for a short period.
However it takes much longer to get strength back. To increase muscle strength by 10% takes about sixty days.
You can maintain muscle strength without aggravating an injury with some simple exercises. By tensing the muscle without moving the joint, known as an isometric contraction, for several seconds a day, you can maintain muscle strength.
You don’t have to work the muscle as hard as you can, you only need to work it at about 20-30% of its maximum (i.e. think about how hard you could tense the muscle and just do about one third of that).
