A badminton player in a long three-game match shows declining performance in the final game. Which combination of factors most likely explains this?

  1. Rising insulin, increased glucose storage in muscles
  2. Depleted glycogen stores, falling blood glucose
  3. Rising adrenaline, faster nutrient absorption
  4. Falling glucagon, reduced release of stored glucose

\(B\)

Show Worked Solution
  • B is correct: As the match continues, glycogen stores in the liver and muscles run low and blood glucose falls, reducing the fuel available for repeated explosive movements.

Other options:

  • A is incorrect: Insulin falls during exercise, so glucose stays available in the blood rather than being stored.
  • C is incorrect: Adrenaline rises, but blood is diverted away from the gut, so absorption slows rather than speeds up.
  • D is incorrect: Glucagon rises during prolonged exercise to release stored glucose from the liver.
