What is catabolism
breaking down
what is anabolism
building up/together opposite of breaking down
when is net muscle protein balance the greatest (most positive)
after exercise and protein ingestion
approximately what rate does protein turn over per day (%)
1-2% per day
In the post exercise period, the MPS response to protein ingestion is enhanced, how long do the effects last
24-48hrs
what does MPS stand for
muscle protein synthesis
to maximise training adaptations, what protein intake per day is recommended?
1.6-2kg per day
which amino acid is important in initiating muscle protein synthesis
Leucine
during a diet what happens to protein synthesis
its reduced
What is sports nutrition
The study and practice of nutrition and diet as it related to athletics performance. concerned with the type and quantity of fluid and food taken in by the athlete and deals with nutrients such as vitamins, minerals, supplements and organic substances.
why do we communicate nutrition science?
• helps people know about a balanced diet • reduce obesity therefore reduce strain on NHS • More people can work if healthier • food underpins cultures • food banks/ free school dinners • promote yourself as an expert
what is the deficit model of science communication
experts speak at society and they don’t understand
what is the dialogue model of science communication
there is communication between experts, governments, society, trade and industry
what is the gradient model of science communication
science communication links science and the public
what is the rhetoric of science
links these 3: ethos- trusthworthyness, tone style logos- facts, stats, case studies, scientific evidence pathos- emotional impact, personal connection
where does science communication go wrong
innacurate bias boring overcomplicated oversimplified
what is ATP hydrolysis
the breakdown of ATP using water ATP + h20 –> energy + ADP + H+
what is ATP resynthesis
creating ATP ADP + Pi –> ATP
Where is ATP stored
in the muscle
what processes aid the resynthesis of ATP
Creatine phosphate system Glycolysis Oxidative phosphorylation
where is glycogen stored
in the liver
where are triglycerides stored
in the adipose tissue
what processes are part of substrate level phosphorylation
PCr breakdown Glycolysis
what energy systems are working at intense exercise
PCr, glycolitic and oxidative phosphorylation
