Exercise is essential for managing diabetes and maintaining a healthy lifestyle. However, the time and amount can lead to signs of low blood sugar. The body uses carbs for energy. When you work out or go for a run, glucose levels can drop. Additionally, working out too close to bedtime can cause nighttime hypoglycemia.
Hypoglycemia can also be experienced by non-diabetic athletes. Often referred to as "bonking," it occurs when the person totally depletes their glycogen levels. So once someone experiences the dip and related symptoms, they'll make sure to prevent it from happening a second time.
A journal entry in Nutrition Reviews explains the importance of glycogen metabolism for coaches and athletes in April 2018,
"For anyone engaged in regular physical activity (eg, laborers and soldiers) or sports training, adequate restoration of muscle and liver glycogen stores from day to day is required to sustain the capacity for continued exercise and high-intensity activity."
The study continues to explain these depletions can reduce performance and compromise physical and mental health.
