Unit 3 AOS 2 PE Review

The area indicated by number 1 is known as

• excess post-exercise oxygen consumption (EPOC)

• Oxygen deficit

• oxygen debt

• steady state

During the period indicated by the number 2, oxygen demand is being met by oxygen supply. Which energy system(s) supplies most of the energy for exercise during this period?

• ATP-PC

• Aerobic Energy system

• Anaerobic systemS

• anaerobic glycolysis

During the period indicated by the number 3, what is happening physiologically in the body?

• Blood lactate levels are increasing

• core body temperature is increasing

• oxygen is restored to myoglobin and blood

• oxygen demand is not being met by the body

Trent, Grant and Adam all have a VO2 Max of 3.8L/min.

Trent weighs 105kgs

Grant weighs 65kgs

Adam weighs 97kgs.

Who has the higher relative VO2 Max and most likely to a 10km race?

• Trent

• Adam

• Grant

• Trent and Adam

The estimated maximum heart rate of a 30 year old is:

• 190 bpm

• 200 bpm

• 210 bpm

• 220 bpm

The energy system most dominant on this graph at the 45 second mark of this graph is

• ATP-PC

• Anaerobic Glycolysis

• Aerobic Glycolysis

• Aerobic Lipolysis

At the 60 second mark select the option the correctly describes what has happened:

• The aerobic energy system takes over dominance and the other systems stop producing ATP

• The aerobic system starts producing ATP

• The aerobic system becomes the most predominant energy system meaning it now produces the most or greater than 50% of total ATP

• The anaerobic systems stop producing energy and the aerobic energy system is the most dominant energy system

The likely reason for the short sprint having the higher average speed is due to:

• The ATP-PC and Anaerobic Glycolysis system being most predominant which produces a higher yield of ATP meaning a faster overall speed can be achieved

• The ATP-PC and Anaerobic Glycolysis system being most predominant which produces a faster rate of ATP meaning a faster overall speed can be achieved

• The aerobic energy system being most predominant which produces a faster rate of ATP meaning a faster overall speed can be achieved

• The aerobic energy system being most predominant which produces a higher yield of ATP meaning a faster overall speed can be achieved

After the completion of a crossfit workout of the day lasting 40 minutes an appropriate nutritional recovery strategy that could be used to enhance recovery would be

• Consumption of a meal high in FAT

• Consumption of carbohydrate meal to replace glycogen stores

• Consumption of protein to initiate the repair of damaged muscle tissue

• Consumption of both carbohydrate and protein to replace glycogen stores and raise insulin levels to assist protein repair muscle tissue

The phosphate recovery test is a test that requires a person to complete 8 sprints of 7 seconds in duration each, with a 30 second passive recovery after each sprint. A score based on the cone they get to from the start line is given after each sprint. The dominant energy system for each sprint is:

• ATP-PC

• Anaerobic Glycolysis

• Aerobic

• Aerobic and Anaerobic glycolysis
