Post-performance
Post-performance
nutrition should focus on replacing energy stores as quickly as possible. This
is best achieved through proactive recovery enabling optimisation of body
repair and regeneration processes. Post-performance nutrition involves
replacing energy stores following exercise as quickly as possible. How well
athletes recover after a session of exercise will have an impact on their
ability to perform in future training and competition.
A
post-performance nutritional plan aims at returning the body to its pre-event
state as soon as possible. This is best achieved through proactive recovery,
i.e. active recovery rather than prolonged rest. This means that refuelling
(carbohydrate) and rehydration (fluid and electrolytes) should begin
immediately (ideally, within 30 minutes) and continue for 8-12 hours following
the performance. This enables optimisation of body repair and regeneration
processes.
The best way
to recover is to act quickly and eat food with high carbohydrate content. An
intake of foods with a high glycaemic index (GI) is most beneficial as it
raises blood glucose levels faster than low GI foods. Rehydration should involve
an increased level of electrolyte and carbohydrate than previously prescribed
(during activity) as well as an increased quantity. Dietary protein consumed
immediately after a session is taken up more effectively by the muscle for
rebuilding processes (as exercise can cause a substantial breakdown of muscle
tissue) than is protein consumed hours afterwards. Active rest (light exercise
such as walking and stretching) enhances recovery of body systems damaged by
the stress of the activity.
It can be
difficult for athletes who take part in multiple training sessions each day or
who train for extended periods of time to replace fuel and fluid stores
adequately. Extensive, strict planning is required.
