Final- anerobic/ aerobic fitness

Question 1

functional significant of lactate threshold

Answer 1

• functional index of muscle metabolism
• lactate inhibits lipolysis
• accelerated glycogen utilization above lactate threshold

Question 2

high levels of H+ interfere with

Answer 2

enzyme activity

-cross bridge attachments

Question 3

maximal lactate steady state

Answer 3

the highest exercise intensity at which blood lactate conc des not increase beyond the initial transient during constant load exercise

Question 4

lactate minimum speed

Answer 4

speed of locomotion at which blood lactate reaches a minimal value during incremental exercise test

Question 5

lactate threshold

Answer 5

is the exercise intensity that is associated with a substantial increase in blood lactate during an incremental exercise test

Question 6

onset of blood lactate accumulation

Answer 6

intensity of exercise at which blood lactate conc reaches 4 mm

Question 7

imdv. anaerobic threshold

Answer 7

intensity of exercise identified by a line drawn from a recovery lactate conc tangent to the lactate conc observed during an incremental test

Question 8

ventilatory threshold

Answer 8

increase in ventilation becomes disproportional to the increase in power output or speed of locomotion during an incremental exercise test

Question 9

control of ventilation

Answer 9

• feedback (central and carotid chemoreceptors)

- Feedforward (central command, muscle feedback)

Question 10

lactate threshold occurs b/w what percentages of vo2max

Answer 10

57-92%

Question 11

LT identification

Answer 11

1. changes in lactate concentration during and after ex
2. power output at a blood lactate conc of 4mmol
3. Power output at the intersection of a tangent to alactate curve that is parallel to the slope of 1mmol increase in 3 mins
4. Power output that immediately precedes the first 1mmol rise

Question 12

VT identification

Answer 12

1. RQ=1

2. V slope: the power output at which a steeper increase of vco2 as compared with vo2 occurs

Question 13

7 basic principals of exercise program design

Answer 13

1. specificity
2. overload
3. progression
4. initial values
5. interindividual variability
6. diminishing returns
7. reversibility

Question 14

how does initial values correlate to fitness

Answer 14

individuals w low initial levels will show greater % gains and faster rate of improvement in training

Question 15

what does inter individual variability mean

Answer 15

individual responses to a training stimulations are unique to the specific client

Question 16

canadas PA guidlines

Answer 16

150 mins pew week of moderate intensity PA

Question 17

How to calculate HR intensity

Answer 17

1. predict HR max

2. calculate target HR (if want 55% HR then- 0.55 * HR max)

Question 18

How to calculate HRR

Answer 18

1. Predict HR max

2. Put it in to HRR caluclation

Question 19

what is a HRR for moderate intensity, adavanced

Answer 19

mod-40-60%

advanced- 60-85%

Question 20

heal strike running results in

Answer 20

results in over striding

• increases braking/impact
• increased musclar force required

Question 21

How to figure out training zone

Answer 21

figure out HRR (max -resting)

HRR* (percent workrate)+resting

Question 22

What is AB in endurance racing

Answer 22

where RQ is .85
