How much energy per gram in carbs
4kcal/g
How much energy per gram in fats
9kcal/g
How much energy per gram in protein
4kcal/g
what are carbs stored as and where
exists as glucose and stored in muscle and liver as glycogen
importance of carbs
provides energy, exclusive energy source for nervous system, regulates fat and protein metabolism
does fat produce a high or low ATP yield
high energy yield but ATP production is slower than carbs
importance of fats
makes up cell membranes and nerve fibres, provides 70% energy at rest, cushions vital organs, produces all steroid hormones, transport and stores fat soluble vitamins, maintains body temperature.
proteins role in energy production
can be used as a fuel source, but their role is limited
importance of protein
helps build, repair and maintain tissues. Maintains cell structure, produces haemoglobin, enzymes and many hormones. Can be an energy contributor
exercise adaptive thermogenesis (EAT) meaning?
the energy expended during exercise/planned exercise
thermic effect of food (TEF) meaning?
the energy required for digestion, absorption, and disposal of ingested nutrients.
non exercise adaptive thermogenesis (NEAT) meaning?
the energy expended that is not the others (walking, typing,)
basal metabolic rate (BMR) meaning?
the amount of energy per unit of time that a person needs to keep the body functioning at rest.
factors to consider for individualisation?
- bioenergetics and logistics of sport, training, and competition schedules
- living arrangements, access to food, travel schedule
- anthropometrics
- career
- sporting objectives
- lifestyle and social factors
- health history
