Type 1 Diabetes & Exercise

Living with Type 1 Diabetes (T1D) doesn't mean sitting on the sidelines. Regular exercise is one of the most powerful tools available for managing T1D — but it does require some extra planning. This guide walks through the key benefits, practical recommendations, and safety strategies to help people with T1D move with confidence.

How Exercise Helps

The evidence is clear — regular physical activity delivers meaningful benefits for people living with Type 1 Diabetes across three key areas.

Cardiovascular Health

People with T1D face a higher risk of cardiovascular disease. Regular aerobic exercise strengthens the heart, improves cholesterol profiles, lowers blood pressure, and reduces the long-term risk of heart-related complications — making it one of the most important lifestyle interventions available.

Mental Wellbeing

Managing T1D can be mentally exhausting. Exercise is a proven mood-booster — it releases endorphins, reduces stress hormones, and eases anxiety and depression. Many people with T1D report that regular movement helps them feel more in control of their condition and their life.

Quality of Life

Beyond the clinical numbers, exercise helps people with T1D maintain a healthy weight, build functional strength, sleep better, and participate fully in daily activities. It supports independence, energy levels, and long-term wellbeing — not just glucose control.

What to Aim For

The following table summarises exercise guidelines and practical considerations specific to people living with T1D. These are general recommendations — an Accredited Exercise Physiologist can tailor a program to individual goals, fitness level, and glycaemic patterns.

Frequency

Most days of the week

Aim for at least 3–5 sessions per week, with no more than 2 consecutive days without activity.

Carb / Insulin Adjustment

Plan sessions around meals and insulin timing to minimise glucose fluctuations.

Duration

150 min/week (moderate) or 75 min/week (vigorous)

Break sessions into manageable chunks — even 10–20 minute bouts count toward the weekly total.

Carb / Insulin Adjustment

Longer sessions may require additional carbohydrate intake before, during, or after exercise.

Intensity

Moderate to vigorous

A mix of aerobic (e.g. walking, cycling, swimming) and resistance training is recommended for optimal benefits.

Carb / Insulin Adjustment

High-intensity intervals (HIIT) may cause a transient rise in blood glucose — monitor closely and adjust as needed.

Type

Aerobic + Resistance

Aerobic exercise improves heart health and insulin sensitivity. Resistance training builds and preserves muscle mass, improving glucose uptake.

Carb / Insulin Adjustment

Starting with resistance exercise before aerobic may help blunt hypoglycaemia risk during combined sessions.

Staying Safe

Exercise is safe and strongly recommended for people with T1D — but preparation is everything. Here are the key safety considerations to keep in mind.

Blood Glucose Monitoring

  • Check blood glucose before, during (if session > 30 min), and after exercise.
  • Target pre-exercise BGl: 7–10 mmol/L. Delay exercise if BGL < 5 mmol/L or ≥ 15 mmol/L with ketones.
  • Keep fast-acting carbohydrates (e.g. glucose tablets, juice) accessible at all times during exercise.
  • Post-exercise hypoglycaemia can occur up to 12–24 hours later — monitor overnight if exercising in the afternoon or evening.

Hypoglycaemia Action Plan

  • Mild-moderate hypo (BGL < 4 mmol/L): Stop exercise immediately. Consume 15–20 g fast-acting carbohydrate (e.g. 4–6 glucose tablets or 150 mL fruit juice).
  • Recheck BGL after 15 minutes. Repeat carbohydrate if still < 4 mmol/L.
  • Do not resume exercise until BGL is ≥ 5 mmol/L and symptoms have resolved.
  • Always exercise with a buddy or inform staff of your condition. Wear medical identification.

CGM Coordination

  • Continuous Glucose Monitors (CGMs) provide real-time glucose data and trend arrows — a valuable safety tool during exercise.
  • Use trend arrows to anticipate direction: a falling arrow during activity warrants a proactive carbohydrate top-up before reaching the hypo threshold.
  • Note that CGM readings may lag fingerprick measurements by 5–15 minutes; use fingerprick to confirm before treating a hypo.
  • Discuss CGM alert settings and exercise-specific targets with your endocrinologist and exercise physiologist.
