Quiz on the Effects of Exercise on Muscles

What is muscle hypertrophy?

• Increase in muscle mass due to exercise

• Decrease in muscle mass due to exercise

• Increase in fat tissue

• Decrease in muscle strength

Which type of exercise primarily uses Type I muscle fibers?

• Sprinting

• Weight lifting

• Aerobic exercise

• Anaerobic exercise

What is lactic acid?

• A type of muscle fiber

• A form of muscle fatigue

• A chemical compound produced during high-intensity exercise

• A type of aerobic exercise

What is the primary energy source for anaerobic exercise?

• Glucose and glycogen

• Fat

• Protein

• Oxygen

What happens during aerobic exercise?

• Muscles use Type II fibers

• Muscles experience high fatigue

• Muscles rely on oxygen for energy

• Muscles produce more lactic acid

What is a short-term effect of anaerobic exercise?

• Fat loss

• Lactic acid buildup

• Muscle hypertrophy

• Increased muscle endurance

What is cross education in muscle training?

• Training both sides of the body equally

• Gaining strength in opposite muscles

• Training only one muscle group

• Using aerobic exercise exclusively

What is the main characteristic of Type II muscle fibers?

• They are used for endurance

• They are fast-twitch fibers

• They do not produce lactic acid

• They are slow-twitch fibers

What is a long-term effect of consistent anaerobic strength training?

• Muscle hypertrophy

• Increased muscle endurance

• Decreased muscle mass

• Increased fat storage

What causes muscle soreness after exercise?

• Small tears in muscle fibers

• Lactic acid accumulation

• Dehydration

• Excessive oxygen intake
