Metabolism and Energy Systems Training

Question 1

what is beta oxidation?

Answer 1

we eat food that contains fat, stored as fatty acids, fatty acids will make themselves available and go through beta oxidation (fatty acid oxidation)
- fuel is fat
- aerobic and happens in mitochondria
- produces a lot of ATP
- leads to Acetyl-CoA and then carries on to krebs and then ETC

Question 2

what is the net ATP production of Palmitic Acid Oxidation?

Answer 2

129 ATP
- uses NADH and FADH

Question 3

What does beta oxidation yield?

Answer 3

high levels of ATP

Question 4

Total yield of ATP produced in glycolysis, krebs and ETC?

Answer 4

36-38

Question 5

which systems are anaerobic?

Answer 5

ATP-CP and glycolysis

Question 6

words that mean the oxidative system?

Answer 6

oxidative, aerobic, alactic

Question 7

words that mean the glycolysis or ATP-CP system?

Answer 7

glycolytic, anaerobic, lactic

Question 8

what is a work:rest ratio?

Answer 8

comparing duration of exercise to the duration of rest
- each energy system has preferred work:rest ratios

Question 9

what work:rest ratio would be used for the ATP-CP system? why?

Answer 9

1:12 up to 1:20 because it is short duration of work but very high intensity (ex. 5-15 sec: several min)

Question 10

what are the adaptations of the ATP-CP system training?

Answer 10

• better at storing fuel in the muscle
• being efficient at making creatine phosphate available during exercise
• increased peak power and muscle growth
• amount and recruitment efficiency of motor units
• type IIx muscles are targeted

Question 11

what work:rest ratio would be used for the oxidative system? why?

Answer 11

1:1 to 1:3
- endurance athletes are doing longer work

Question 12

what are the adaptations of the oxidative system training?

Answer 12

• improved VO2 max
• improved ability to use oxygen to produce energy in the form of ATP and propel our body forward in endurance activity
• increase the number and activity of enzymes
• increase the number of capillaries in the muscle
• increase the number of mitochondria
  increase the number of glycogen stored in the muscle
• becomes more efficient at using fat before it relies on carbs

Question 12

what work:rest ratio would be used for the glycolysis system? why?

Answer 12

1:3 to 1:5 because its more intense than aerobic training but not as much as ATP-CP

Question 13

what are the adaptations of the glycolysis system training?

Answer 13

• enhances enzyme amount and function
• increased average power
• anaerobic threshold shift
• type IIa muscle fiber targeteda

Question 14

how does marathon runners anaerobic threshold differ?

Answer 14

• they delay the onset of lactate accumulation
• they can achieve higher work rates and more exercise before their body goes into acidosis state and they need to stop
