Question

Willianne is training to run in a half-marathon (13.1 miles). She has run in 5K and 10K races before, but never in a half-marathon. To prepare, Willianne has been following a training plan for the past several months. What are some of the specific effects of endurance training on carbohydrate metabolism?

Answer 1

Endurance training promotes adaptations and shifts in substrate utilization and increases the maximal capacity for carbohydrate oxidation (as well as fat oxidation).

Step-by-step explanation:

Endurance training reduces the reliance on carbohydrate as a source of energy during submaximal excercise. There is an increased effectiveness of insulin to stimulate glucose transport, there’s also an enhanced glucose uptake. Trained muscles are also characterized by increased concentration of glycogen, which is an important factor in the decreased rates of fatigue with prolonged exercise. As it was said, exercise training can increase insulin sensitivity and improve overall glucose homeostasis, which are important in cases of metabolic deseases.
