• To increase muscle mass

What is the term for the volume of blood ejected from the heart per beat?

• Blood Pressure

• Cardiac Output

• Stroke Volume

• Heart Rate

What is the primary reason elite athletes can work at higher intensities for longer periods of time?

• Increased lung capacity

• Higher body temperature

• Greater tolerance to lactic acid

• Improved eyesight

What is the effect of lactic acid on muscles during high-intensity exercise?

• It increases muscle endurance

• It strengthens the muscles

• It causes fatigue and loss of function

• It reduces muscle flexibility

What is the significance of building up a tolerance to lactic acid in athletes?

• To work harder for longer periods

• Stroke volume

What is the primary source of energy for muscles during high-intensity exercise?

• Protein

• Carbohydrates

• Fats

• Vitamins
