Summary

This study looked at how different levels of exercise change the bacteria in the gut of people with type 2 diabetes. Forty adults with type 2 diabetes did either moderate or high-intensity endurance and strength training for 16 weeks. Researchers compared changes in blood sugar and gut bacteria between the two groups to learn more about how exercise affects health.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 19 - 64 years old; * Diagnosed with type 2 diabetes; * An HbA1c \>= 7.0%; * Not currently meeting the recommended levels of physical activity for optimal health (i.e., 150 minutes of moderate-to-vigorous physical activity and 2+ days/week of resistance training); * Average less than 10,000 steps per day over the last seven days; * No change in diabetes medications over the last three months. Exclusion Criteria: * Not diagnosed with type 2 diabetes; * Partaking in a self-reported regular exercise regimen, defined as consistent participation in running or jogging activity, attending exercise classes every week, or averaging 10,000 steps per day or more over seven days; * Currently performing two days of resistance training per week; * Having an injury that would prevent safe participation in the intervention; * A self-reported diagnosis of low iron concentrations, anemia, or being treated for these conditions; * A diagnosis of any red blood cell altering condition (i.e., sickle cell anemia, poikilocytosis); * Currently living with any cardiovascular disease which would impact the ability to participate in exercise safely; * Currently prescribed any medication which would impact the ability to use a heart rate monitor to accurately track intensity.
