Sample Answer
The digestive system
- Requires dietary fats to effectively absorb fat-soluble vitamins (A, D, E, K), showing the interrelationship between nutrient absorption and movement.
- Vitamin D absorbed through this process enables calcium absorption and bone health, directly affecting movement quality.
The endocrine system
- Uses vitamin D as a hormone to influence muscle strength and coordination.
- Optimal vitamin D levels enhance muscle protein synthesis leading to improved movement efficiency, while deficiency causes weakness.
- Vitamin E functions as an antioxidant protecting cell membranes during exercise, with absorption dependent on dietary fat intake.
- This antioxidant protection maintains muscle cell integrity during intense movement, supporting sustained performance and reducing exercise damage.
