L3.3 Exercise and Metabolic Diseases

Question 1

What is the grouping/cycle of the metabolic disease?

Answer 1

1) Central Obesity → 2) insulin resistance → 3) Altered cholesterol → 4) ↑BP → ↑Triglycerides → 1) results in central obesity

Question 2

What is the effect of changing diet alone to tackle obesity?

Answer 2

• Changing diet alone → cannot completely solve obesity
• Will have initial weight loss → but regain of weight due to change in ‘appetite’ hormones

Question 3

What is the relationship between exercise and metabolic disease?

Answer 3

• ↑physical activity (type/intensity/duration affects weight loss) →
• ↓risk of developing & having metabolic disease
• ↓excess fat
• Weight not put back on unlike diet change

Question 4

What is the effect of different types of exercise?

Answer 4

• Resistance → ↑lean mass, ↓fats (small), ↑insulin sensitivity (small)
• Aerobic → ↑lean mass (small), ↓fats, ↑insulin sensitivity
• Combined → ↑lean mass, ↓↓fats, ↑↑insulin sensitivity

Question 5

What are the benefits of exercise on metabolism?

Answer 5

• ↓body weight (↓fat cell size)
• ↑insulin sensitivity (↓insulin resistance)
• ↓triglycerides, ↑HDL (change occurs regardless of intensity/duration/type)
• ↓BP
• ↑Glucose disposal (↑GLUT4 expression)
  
  • ↓Glucose to liver for lipogenesis
  • Redirected to muscles to store as glycogen
