This lecture provides an introduction to the science of sport nutrition,
in it, I'll explain why nutrition is so important for athletes and games players.
My name is Michael Gleeson, and I'm Emeritus Professor of Exercise Biochemistry
at Loughborough University.

After this lecture:
you should appreciate the importance of nutrition in sport;
you should understand why nutrition guidelines need to be sport-specific,
and, as far as possible, personalised to the needs of the individual;
you should know why an understanding of nutrient roles and energy metabolism
is important in sport nutrition;
and you should appreciate that you need to understand the training and competition
demands of your chosen sport, because these very much impact on the nutritional requirements;
You should also realise that nutrition is important for performance,
but also for other issues such as recovery, health, immune function, sleep,
training adaptation, muscle hypertrophy, weight maintenance, body composition, and injury rehabilitation.

Let's first think about what athletes and games players want to be able to do.
They want to be able to perform well in competitions, obviously, that's the main aim.
To do that they've got to be able to train well and effectively.
They want to maintain a consistent level of performance throughout a season.
They want to recover quickly from their training sessions, or their competition.
They want to avoid burnout and over-training.
Importantly, they'll want to remain healthy and avoid injury, because illness and injury
are the two main reasons for missing either training or competition.
In fact, a good diet - appropriate food and fluid intake at the right times -
can help all of these things.
