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
What is the primary source of ATP during aerobic exercise?
Fat
Glucose
Lactic acid
Protein
What is the effect of sustained aerobic respiration on muscle metabolism?
Decreases oxygen availability
Shifts to fat as the primary source of ATP
Increases lactic acid production
Increases muscle fatigue
What is the role of calcium in muscle fatigue during aerobic exercise?
It increases energy production
It causes ion shortages
It enhances muscle contraction
It prevents lactic acid buildup
What type of exercise is characterized by high-intensity muscle contractions?
Aerobic exercise
Flexibility training
Anaerobic exercise
Endurance training
What is the main focus of anaerobic strength training?
Reducing fat
Improving flexibility
Increasing muscle mass
Gaining endurance
