lec 10

Question 1

where does immediate energy come from?

Answer 1

ATP-CrP

Question 2

what does anaerobic mean?

Answer 2

without oxygen

Question 3

what % can we break ATP, CP down to?

Answer 3

can only break down to 40%

Question 4

what happens to anaerobic capacity as we grow

what age do we hit adult capacity?

Answer 4

it increases as children grow (18 around 100% adult capacity)

Question 5

how do we measure anaerobic performance

Answer 5

wingate test

Question 6

what is oxygen debt? who would have larger gap athletes or normal people

Answer 6

normal people would have a larger gap (look in lec 9

Question 7

factors that may affect anaerobic performance in children and adolescence. what happens with them as we grow - increase or decrease?

muscle mass
maximal oxygen debt per unit muscle mass
rate of anaerobic glycolysis
neuromotor control
submaximal and maximal blood lactate levels -
submaximal and maximal muscle lactate levels

Answer 7

muscle mass - increases
maximal oxygen debt per unit muscle mass - increases
rate of anaerobic glycolysis - increases
neuromotor control - improves
submaximal and maximal blood lactate levels - increases
submaximal and maximal muscle lactate levels - increases

Question 8

what happens to muscle mass as we grow?

Answer 8

increases

Question 9

maximal oxygen debt per unit muscle mass as we grow?

Answer 9

increases

Question 10

what happens to rate of anaerobic glycolysis as we grow?

Answer 10

increases

Question 11

submaximal and maximal blood lactate levels as we grow?

Answer 11

increases

Question 12

submaximal and maximal muscle lactate levels as we grow?

Answer 12

increases

Question 13

what happens to blood pH at end of anaerobic or maximal aerobic exercise?

Answer 13

decreases

Question 14

what happens to neuromotor control as we grow?

Answer 14

improves

Question 15

what is muscle strength?

Answer 15

the amount of force produced in a single maximal contraction

Question 16

what are some measures of strength?

Answer 16

static or isometric strength, explosive strength (power) and muscular endurance

Question 17

what is isometric strength

Answer 17

force exerted without and changes in muscle length

eg. trying to lift a house

Question 18

what is isotonic contraction

Answer 18

its what we are doing when we are lifting weights

Question 19

what is explosive strength? example

Answer 19

ability for muscle to release max force/torque in shortest time possible

eg weight lifter

Question 20

what is muscular endurance? eg

Answer 20

repeat or maintain muscular contractions over time

eg. doing 10 000 pushups

Question 21

what happens with strength as we get older?

Answer 21

it increases we get stronger - until age 30 and then starts to decrease

Question 22

does puberty play a role in strength increase?

Answer 22

yes

Question 23

what do we know about resistance training in children?

Answer 23

resistance training does increase strength in prepubescent individuals but they do not develop muscle hypertrophy due to a lack of testosterone

Question 24

what happens to anaerobic performance as we age?

Answer 24

performance declines

Question 25

what is maintained better as we age muscular endurance or strength?

Answer 25

muscular endurance

100m sprint vs 10km run

Question 26

what happens to peak power as we age?

Answer 26

declines
