This video tutorial covers the long-term effects of exercise, focusing on how aerobic and anaerobic training impact the heart and overall fitness. It explains physiological changes like cardiac hypertrophy and bradycardia, and how these adaptations improve athletic performance. The tutorial also discusses lactic acid tolerance in anaerobic exercise, using examples like Elliot Kipchoge and Usain Bolt to illustrate key points. The lesson concludes with guidance on applying the knowledge to exam questions.

What are the three learning objectives of this lesson?

• To identify changes in muscle strength, understand effects on bones, and learn about diet.

• To identify heart changes after training, understand effects on the body, and how blood tolerates lactic acid.

• To learn about different sports, understand training schedules, and diet plans.

• To identify changes in lung capacity, understand effects on the brain, and learn about hydration.

What happens to the heart's stroke volume as a result of aerobic training?

• It remains the same.

• It decreases.

• It fluctuates.

• It increases.

Why can trained athletes work at higher intensities for longer periods?

• Because they have more muscle mass.

• Because their heart can transport more oxygen to muscles.

• Because they consume more calories.

• Because they have a higher body temperature.

What is the technical term for the heart becoming larger due to training?

• Bradycardia

• Cardiac hypertrophy

• Tachycardia

• Myocardial infarction

What is bradycardia?

• A resting heart rate below 60 beats per minute.

• A condition where the heart beats too fast.

• A type of heart disease.

• An increase in blood pressure.

How does high intensity interval training (HIIT) help in building lactic acid tolerance?

• By increasing the resting heart rate.

• By reducing the need for oxygen.

• By exposing muscles to lactic acid frequently.

• By increasing muscle mass.

Why do muscles tire quickly during high intensity activities?

• Due to dehydration.

• Because of low blood sugar levels.

• Because of a lack of protein.

• Due to the accumulation of lactic acid.

What is the main benefit of building up a tolerance to lactic acid?

• Increased muscle size.

• Improved flexibility.

• Better coordination.

• Ability to work harder for longer.

What should be the next step after learning about the long-term effects of exercise?

• Starting a new topic immediately.

• Applying the knowledge to past exam questions.

• Ignoring the information learned.

• Taking a break from studying.
