18
Q

anaerobic energy systems

A
  • phosphagen system
  • glycolysis
19
Q

phosphagen system

A

no lag time, 6 seconds, depends on phosphocreatine, limited ability to make ATP so relies on stores

20
Q

glycolysis

A

90-120 seconds, depends on glucose
1. 1 glycose = 2 pyruvate
2. Go to krebs cycle

21
Q

aerobic energy systems

A
  • Krebs cycle
  • ETC
22
Q

Krebs

A

needs energy to start, form 2 atp

23
Q

glucose and fructose absorbed into SI at _____ and ____ g/h

A

60
25

24
Q

absorbing different sources of carbohydrates during exercise term

A

multiple transportable carbohydrates

25
Q

benefit of consuming carbs during exercise

A

a. Helps stamina
b. Helps the body not use protein (muscles)
c. Helps concentration

26
Q

carbs for 30-60 min

A

none (mouth rinse)

27
Q

carbs for 60 minutes to 2 hrs

A

30g/h

28
Q

carbs for 2-3 h

A

60g/h

29
Q

carbs for 3+ h

A

90g/h

30
Q

how muscle glycogen helps support team sport players

A

a. Team sport athletes need more stamina
b. Prolonged periods of multiple sprints drain muscle glycogen stores (e.g. glycolysis), leading to a decrease in power output and a reduction in the general work rate during training and competition. Adopting nutritional strategies to ensure that muscle glycogen stores are well stocked prior to training and competition helps delay fatigue
c. Helps with motor skills

31
Q

post exercise glycogen resynthesis methods

A
  • 1.2 g/kg carbs alone
  • 0.8 g/kg + 0.4 g/kg carb and protein
32
Q

best time to consume carbs and why

A

a. 30-60 minutes post-exercise to take the most advantage of GLUT4 that is already at the muscle cell and ready to transport glucose from blood to muscle.

33
Q

major factors that influence glycogen synth after exercise

A

a. Glycogen synthase as rate limiting enzyme
b. Rapid phase = more GLUT4, insulin independent, more synthase activity responsive to less muscle glycogen content
c. Slow phase = insulin dependent, still synthesizing but at much slower rate
d. More muscle glycogen concentration, less GLUT4 activity

34
Q

how much glycogen can be stored in both liver and muscle

A
  • liver = 80-100g
  • muscle = 300-500g
35
Q

brief exercise carbs

A

< 45 mins
none

36
Q

sustained high-intensity

A

45-75 m
- 30g or less

37
Q

endurance

A

1-2.5 h
- 30-60g/h with MTC

38
Q

stop and start sports

A

90 m
- up to 50-60g/h with MTC

39
Q

ultra endurance

A

2.5-3+ h
- up to 90g/h with MTC

40
Q

light exercise daily

A
  • low intensity
  • 3-5g/kg
41
Q

moderate exercise daily

A

1 h/day
- 5-7g/kg

42
Q

high exercise daily

A

1-3h/d
- 6-10g/kg

43
Q

very high exercise daily

A

> 4-5h/d
- 8-12 g/kg
