Nutrition - glutamine Flashcards
What is glutamine?
The most abundant aa in muscle and plasma
What are the roles of glutamine?
Maintenance of acid-base balance in acidosis
Regulation of protein synthesis and degradation
Provides a nitrogen precusor for nucleotide synthesis
Fuel source for cells
Prior to exercising - what is glutamine supplementation hypothesised to do?
Enhance the blood buffering capacity and enhance performance
Post exercise - what is immediate glutamine supplementation hypothesised to do?
Positive effects of immune function
- CHO and protein replace glucose and glutamine (plasma glutamine drops post exercise)
How would repeated bouts of HI influence plasma glutamine?
May induce a decrease
How does modest exercise effect immune function?
May stimulate an immune response and protect against minor infection
How does HI effect immune function?
May depress immune system and increase risk of illness
What does glutamine supplementation do upon immunosuppression?
Doesn’t appear to reverse any exercise induced immunosuppression
