Which energy system is the most efficient at producing ATP but requires oxygen to function?

• Aerobic energy system

• Anaerobic energy system

• Oxygen energy system

• Aerobic respiration system

What is the main energy source for the ATP-PC energy system?

• Lactic acid

• Adenosine triphosphate (ATP)

• Phosphocreatine (PC)

• Glycogen

During which type of exercise does the lactic acid energy system become the dominant energy provider?

• Moderate-intensity exercises lasting 10-20 minutes

• Anaerobic exercises lasting less than 10 seconds

• Low-intensity exercises lasting over 30 minutes

• High-intensity exercises lasting from about 30 seconds to 2 minutes

What is the term used to describe the interaction and coordination between different energy systems during physical activity?

• Energy System Cooperation

• Energy System Synchronization

• Energy System Collaboration

Which type of muscle fiber is more fatigue-resistant and is primarily used during endurance activities?

• Type IV muscle fibers

• Type I muscle fibers

• Type II muscle fibers

• Type III muscle fibers

Fast twitch muscle fibers are best suited for which type of activities?

• Activities that involve slow, sustained movements

• Activities that require flexibility and balance

• Activities that require endurance and stamina

• Activities that require short bursts of strength and speed

How do energy system adaptations occur in response to consistent training and exercise?

• Energy system adaptations occur through increased mitochondrial density, improved oxygen delivery, enhanced glycogen storage capacity, and optimized fuel utilization.

• Energy system adaptations occur through decreased mitochondrial density

• Energy system adaptations occur through limited glycogen storage capacity

• Energy system adaptations occur through reduced oxygen delivery
