7.5.3 Health Benefits of Regular Exercise

• Regular exercise is defined by its frequency, intensity, time, and type
• What are three cardiovascular benefits of regular exercise?

  Improved heart function, lower blood pressure, reduced risk of heart disease
• The ideal blood pressure is less than 120/80 mmHg.
• Regular exercise can expand tidal volume, allowing for more air intake during each breath
• How does exercise improve gas exchange in the lungs?

  Better oxygen and CO2 exchange in alveoli
• Exercise strengthens the muscles responsible for breathing.
• What does the term "frequency" refer to in the context of regular exercise?

  How often you exercise per week
• Regular exercise reduces strain on arteries, lowering blood pressure.
• Match the respiratory benefit of regular exercise with its explanation:

  Increased Lung Capacity ↔️ Expands tidal volume for more air intake

  Improved Gas Exchange ↔️ Better oxygen and carbon dioxide exchange in alveoli
• What does regular exercise do to respiratory function?

  Enhances respiratory function
• Regular exercise increases lung capacity by expanding tidal volume.
• Improved gas exchange in the alveoli is a respiratory benefit of regular exercise.
• Match the respiratory benefit with its explanation:

  Stronger Respiratory Muscles ↔️ Improves breathing efficiency

  Improved Gas Exchange ↔️ Better oxygen and carbon dioxide exchange
• What is the primary focus of respiratory benefits compared to cardiovascular benefits?

  Improving lung function
• Regular exercise increases metabolism by boosting the rate at which the body burns calories.
• Improved insulin sensitivity reduces the risk of type 2 diabetes.
• What energy source does enhanced energy utilization promote during exercise?

  Fats
• Order the musculoskeletal benefits of regular exercise from most related to bone health to most related to joint health:

  1️⃣ Increased Bone Density

  2️⃣ Muscle Hypertrophy

  3️⃣ Improved Joint Health
• Increased bone density reduces the risk of osteoporosis.
• What type of training leads to muscle hypertrophy?

  Resistance training
• Improved joint health enhances flexibility and reduces the risk of injury.
• Match the benefit with its effect:

  Muscle Hypertrophy ↔️ Increases muscle strength

  Improved Joint Health ↔️ Enhances flexibility
• Muscle hypertrophy improves overall muscle strength and endurance.
• What are the four key components of regular exercise?

  Frequency, Intensity, Time, Type
• Frequency refers to how often you exercise per week.
• What does intensity measure in regular exercise?

  How hard your body works
• Time in regular exercise refers to the duration of each exercise session.
• What does the 'Type' component of regular exercise refer to?

  The kind of physical activity
• Match the key element of regular exercise with its description:

  Frequency ↔️ How often you exercise per week

  Intensity ↔️ How hard your body works

  Time ↔️ How long each session lasts

  Type ↔️ The kind of physical activity
• How many key components define regular exercise?

  Four
• Frequency in regular exercise refers to how often you exercise per week
• Intensity in regular exercise measures how hard your body works during exercise.
• What does Time in regular exercise refer to?

  Length of exercise session
• Type in regular exercise refers to the kind of physical activity you engage in
• The four components of regular exercise must be balanced to achieve health benefits.
• What are three cardiovascular benefits of regular exercise?

  Improved heart function, lower blood pressure, reduced heart disease risk
• Ideal blood pressure is less than 120 / 80 mmHg
• Regular exercise enhances circulation by increasing blood flow to muscles and organs.
• What are three respiratory benefits of regular exercise?

  Increased lung capacity, improved gas exchange, stronger respiratory muscles
• Regular physical activity can expand tidal volume, allowing for more air intake during each breath
