Description of intervention(s) / exposure
Blood glucose is measured continuously during two 3-day periods. During one of these 3-day periods, a 1 hour resistance exercise session is performed consisting of the following exercises: Bench Press, Leg Extensions, Upright Row, Lateral Pull-downs, Dumbbell Flys, squats and abdominal crunches. During the other 3-day period no exercise is performed. Each participant acts as their own control and completes both 3-day periods with a minimum of 3 days washout in between.

Outcomes
Primary outcome [1] 4371 0
Blood glucose (measured continuously)
Timepoint [1] 4371 0
Baseline (pre-exercise/control), Day 1 (Exercise/Control session and following evening), Day 1 overnight, Day 2, Day 2 overnight, and Day 3.
Secondary outcome [1] 7376 0
Safety - post resistance exercise hypoglycemia. Hypoglycemic will be assesses by examining blood glucose levels following resistance exercise compared to rest. This will be measured from the continuous glucose monitor downloaded data.
Timepoint [1] 7376 0
Total time spent with blood glucose level below 3.5mmol/l in the 48 hours following resistance exercise compared to rest.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A Treatment session (1-hour resistance exercise) and control (no exercise) is conducted by each participant during the two 3-day periods in random order. Order determined for each partciipant by random selection of sealed envelope containing order.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Total of 16 envelopes - half sealed envelopes contained exercie/rest and half contained rest/exercise.
Masking / blinding
Open (masking not used)
