Balancing Insulin Dosage for a Smooth Workout
When exercising, it's essential to adjust your insulin dosage accordingly. This ensures that you maintain optimal blood sugar levels and minimize potential complications.
A significant amount of research has shown that physical activity can have both short-term and long-term effects on blood glucose control. In the short term, exercise can lower blood glucose by stimulating glycogen breakdown in muscles (1). However, this effect is usually temporary, lasting only up to 24 hours after cessation of exercise (2).
Timing Your Insulin for Exercise Success
To make adjustments, consider your individual insulin needs and schedule accordingly. If you take a mealtime bolus before exercising, delay it by 30-60 minutes if possible or adjust the dosage according to carbohydrate intake. Conversely, if you're planning an intense workout after dinner and are usually on an evening dose of long-acting insulin, move this up one hour prior (3).
Monitoring Insulin Effectiveness
When adjusting your dosages during exercise sessions keep in mind that individual responses can vary significantly based on factors such as overall health status, fitness levels, food intake before the activity. To gain a better understanding consider consulting healthcare providers or registered dietitians who specialize in diabetes care and nutrition (4).
Fine-Tuning Your Exercise Plan
Exercise routine adjustments are also necessary to prevent potential complications like hypo- hyperglycemia during physical activities such as running cycling swimming diving other strenuous exercise regimens. To keep your blood sugar levels within a target range consider incorporating low-to moderate-intensity exercises for 150 minutes or more each week. Furthermore, high-intensity interval training could help in lowering and maintaining optimal HbA1C levels (5).
