Short Term Effects of Exercise on the Muscular System & Energy

What is muscle fatigue?

• Muscle fatigue is caused by lack of sleep.

• Muscle fatigue is the decline in ability of a muscle to generate force.

• Muscle fatigue is the increase in ability of a muscle to generate force.

• Muscle fatigue is a myth.

Explain the concept of lactic acid build-up in muscles during exercise.

• Lactic acid build-up is a result of excessive oxygen intake during exercise.

• Lactic acid build-up in muscles during exercise is a result of anaerobic respiration due to insufficient oxygen availability.

• Lactic acid build-up is caused by dehydration during exercise.

• Lactic acid build-up is a sign of muscle fatigue during exercise.

Describe the short term effects of exercise on the muscular system.

• Decreased blood flow, reduced oxygen delivery, decreased lactic acid production

• Increased blood flow, muscle temperature increases, increased lactic acid production

• Stiffness, decreased flexibility, reduced muscle strength

• Increased heart rate, improved lung capacity, increased bone density

What is oxygen debt and how does it relate to exercise?

• Oxygen debt is the result of excessive water intake during exercise

• Oxygen debt is the body's ability to store excess oxygen after exercise

• Oxygen debt is the amount of oxygen needed to restore the body to its normal state after exercise. It relates to exercise by accumulating when the body cannot supply enough oxygen to the muscles during intense physical activity, leading to anaerobic respiration and the production of lactic acid.

• Oxygen debt is the amount of carbon dioxide produced during exercise. It relates to exercise by accumulating when the body cannot supply enough carbon dioxide to the muscles during intense physical activity, leading to anaerobic respiration and the production of lactic acid.

What is lactate?

• Lactate is a type of sugar that provides immediate energy to muscles.

• Lactate is a type of protein found in muscles that enhances muscle performance.

• Lactate is a byproduct of anaerobic metabolism in muscles when oxygen supply is limited.

• Lactate is a neurotransmitter that signals muscles to stop working.

How does lactate accumulation affect muscle performance?

• Lactate accumulation increases acidity in muscle cells, leading to fatigue and decreased performance.

• Lactate accumulation has no impact on muscle performance.

• Lactate accumulation improves muscle endurance without affecting performance.

• Lactate accumulation decreases acidity in muscle cells, leading to increased performance.

Identify the correct equation for aerobic respiration.

• Oxygen + Glucose = Energy + Sweat + Lactic Acid

• Oxygen + Glucose = Energy + Water + Carbon dioxide

• Oxygen + Glucose = Energy + Sweat + Carbon dioxide

• Glucose = Energy + Lactic Acid

Identify the correct equation for anaerobic respiration.

• Oxygen + Glucose = Energy + Sweat + Lactic Acid

• Glucose = Energy + Water + Carbon dioxide

• Glucose = Energy + Carbon dioxide

• Glucose = Energy + Lactic Acid
