Nitrate and Exercise-induced Cardiac Troponin T in Type 2 Diabetes (NO troponin)
Recruitment status was: Recruiting
Blood cardiac troponin T (cTnT) concentration is a widely used marker of acute cardiac injury. Previous research has shown that type 2 diabetic patients may experience large increments in cTnT levels over the subsequent hours following a single bout of moderate-intensity endurance-type exercise. This phenomenon is likely attributed to cardiac ischemia-reperfusion injury caused by reduced nitric oxide (NO) bioavailability. Recent evidence indicates that ingestion of dietary nitrates dramatically increases the bioavailability of NO, and as such, may be protective against cardiac ischemia-reperfusion injury.
The investigators hypothesize that dietary nitrate supplementation blunts the rise in cTnT levels following exercise in type 2 diabetic patients.

- Cardiac troponin T [ Time Frame: 9 hours, hourly time intervals ]Cardiac troponin T levels will be assessed before exercise and over the 6-hour period following a single session of exercise.
- Plasma nitrate [ Time Frame: 9 hours, hourly time intervals ]Cardiac troponin T levels will be assessed before exercise and over the 6-hour period following a single session of exercise.
- Plasma nitrite [ Time Frame: 9 hours, hourly time intervals ]Plasma nitrite levels will be assessed before exercise and over the 6-hour period following a single session of exercise.
- Blood pressure [ Time Frame: day ]Blood pressure will be measured various time during the day.
