Energy system characteristics

What is the ATP–CP system?

• The system that provides energy for aerobic activities

• The least complicated energy system that produces energy for ATP resynthesis most rapidly

• A system that relies on the muscular stores of glucose

• A system that provides a continuous supply of ATP during exercise

What does the ATP–CP system rely on?

• The muscular stores of glucose

• The muscular stores of amino acids

• The muscular stores of ATP and creatine phosphate

• The muscular stores of lactic acid

What happens to creatine phosphate when it is broken down?

•  It produces energy and carbon dioxide

•  It produces energy and oxygen

• It produces energy and a phosphate group

•  It produces energy and a nitrogen molecule

What happens to creatine phosphate stores during high-intensity activity?

• They increase

• They remain unchanged

• They deplete rapidly

•  They become saturated

How long can the ATP–CP system sustain all-out (maximal) exercise for?

• Approximately 1–2 seconds

• Approximately 2–3 seconds

• Approximately 6–8 seconds

• Approximately 8–10 seconds

What is the predominant energy system used during high-intensity activities such as sprints, throws, and jumps that take approximately 0–10 seconds to perform?

• The aerobic energy system

•  The lactic acid energy system

•  The ATP–CP energy system

•  The glycolytic energy system

Which activity is an example of a powerful movement that relies most heavily on the ATP–CP system?

• The 100-metre sprint

• The 200-metre sprint

• The marathon

• The drive off the tee in golf

What is the energy source for the first few seconds of a 100-metre sprint?

• The aerobic energy system

• The lactic acid energy system

• The glycolytic energy system

• The muscular stores of ATP

What is the energy source for the resynthesis of new ATP from ADP during a 100-metre sprint?

• The aerobic energy system

• The lactic acid energy system

• The glycolytic energy system

•  The muscular stores of creatine phosphate

When do the muscular stores of creatine phosphate become greatly depleted during a 100-metre sprint?

• At the beginning of the race

• Towards the end of the race (from about 6 to 10 seconds onwards)

• After the first few seconds of the race

• They remain unchanged throughout the race
