Q

what are adaptation to exercise that can cause interference in respect to

A
  1. the signalling pathway , strength being blunted by signalling pathway for endurance fitness
  2. time in training demands

Q

while all of following prescriptions will increase SIZE, which is most typically prescribed and why

A

3 sets of 15-25 reps at 50% 1 RM, because this involves the largest number of contractions

Q

What doesnt consider to be neurally-realted adaptation to explosive resistance training

A

dampened excitability of the motor cortex and motor pathways

22
Q

People’s capability to metabolise (oxidise_ fat is improved w/ aerobic training for many reasons - which is not one

A

an increased concentration of the enzyme fatapase in training muscle

23
Q

which is the slowest adaptation from regular aerobic training is

A

left ventricular mass

24
Q

health related benefits of PA show a dose-versus-reponse relation. which BEST reflicts the repsonse to regular PA

A

least healthy people often show the largest health gain

25
Q

vascular response to aerobic-related exercise training include all the following except

A

larger capillaries

26
Q

vascular adaptation to increase training is readily associated with the following except

A

increased risk of atherosclerosis in repsonse to regular exercise training for approx 20% of people

27
Q

the largest adaptation to regular aerobic fitness training would be

A

aerobic enzyme capacity or activity

28
Q

proportion of people in NZ who report being physically active

A

~50% of adults

29
Q

myoglobin is responsible for what

A

making muscle red despite comprising less than 1% of muscle content

30
Q

4 main ways that aerobic performance increases with training

A
  1. increasing VO2 max
  2. increase anerobic threshold
  3. increase endurance capacity
  4. increase threshold capacity
31
Q

measure max aerobic power is a major determinant for what

A

endurance performance in many contexts

32
Q

what is the increase in Preload due to

A

increase Blood volume
increase time filling

33
Q

increase preload means more stretch so what does this mean for contraction

A

stronger contraction

34
Q

decrease in afterload allows for what

A

higher ejection fraction since less work need to eject blood

35
Q

decrease in afterload is due to what

A

increase in capiliarisation, arterial capacities, increase artiole readitivy

decrease TPR

36
Q

do you calculate % HR range

A

(HR-HRrest)/(HRmax-HRrest) *100

37
Q

if soemone has hypohydration what does this mean

A

low - less than normal

38
Q

euhydration means

A

normal state of hydration

39
Q

is hyperhydration a state or a process

A

state

40
Q

dehydration is the process of what

A

losing water

41
Q

what is the daily intake of water people should consume when in temperte and inactive

A

2.5L/day

42
Q

daily intake of water for someone that exercising or in heat

A

12+L/day

43
Q

if someone is hypernatramic what do thay have

A

extra - increased sodium concentration

44
Q

Hypo hydrated + hypernatremia =

A

thirst

45
Q

How do you define sedentary behaviour

A

waking behaviour that has an energy expenditure of less than or equal to 1.5 METs or sitting positon

46
Q

can you be both active and sedentary

A

yes because you might do 30mins of exercise in the morning but be at work sitting all day

47
Q

what uses more muscle fibres getting out of the chair or standing

A

getting out of your chair

48
Q

one day of being sedentary can reduce what

A

brain flow, vascular function, regulation of blood glucose

49
Q

regular breaks enhances what to the muscel and more of waht

A

enhances glucose uptake and more GLUT4

50
Q

where does the most hazardous drinking come from elite or club

A

elite

51
Q

_____ doesnt hasten alcohol clearence

A

exercise

52
Q

strength gains are maintained better than aerobic (T/F)

A

true
