The purpose of this study is to investigate the effect of an exercise training intervention
on the ability of African American males to use insulin properly. Insulin is a hormone that
helps the body use glucose.

This study is designed to assess the effect of exercise training on insulin resistance in
African American males. African American males have higher rates of diabetes and lower
levels of fitness when compared to Caucasian males. A project such as this is necessary
because there is evidence to show that exercise training can reduce the risk of developing
diabetes, though no studies have been conducted in African American males. In addition,
ARTIIS will test the effect adhering to the 2008 Physical Activity Guidelines for Americans
(150 minutes of moderate intensity aerobic activity and 2 days of 20 minutes of muscular
strength activity), on insulin resistance in African American men. This study will provide
important information that can either strengthen or refine current physical activity
recommendations. Furthermore, this intervention will be delivered through community
facilities in order to increase the likelihood that the intervention will be sustainable.

Inclusion Criteria:

- You completed the three run-in screening visits.

- You self-identify as a male of African descent.

- You are 35 to 70 years of age.

- You have a BMI (ratio of your height to your weight) greater than or equal to 25.0
kg/m2 and less than or equal to 40 kg/m2.

- You have a family history of diabetes.

- You are not currently physically active for 20 minutes each time for 3 or more days
per week for the last 6 months. You are not participating in regular muscle building
exercise.

- You are willing to give informed consent, willing to be randomized to either the
healthy living intervention group or the aerobic plus resistance training exercise
group, and willing to follow the protocol for the group to which you have been
assigned.

Exclusion Criteria:

- You drink more than 14 alcoholic drinks per week.

- You plan to move out of the study area within the next 6 months, or plan to be out of
the study area for more than 4 weeks during the course of the study.

- You have another member of your household participating in the study.

- You have serious health conditions that would interfere with the intervention goals

- History of cardiovascular disease (CVD) or disorders and are not under the care of a
physician to treat the condition, or fail to provide written documentation from your
physician indicating that the physician approves of your entering the study

- Have high blood pressure (greater than 155/99 mmHg) and are not under the care of a
physician to treat the condition or fail to provide written documentation from your
physician indicating that the physician approves of your entering the study

- Have a previous diagnosis of diabetes (Type 1 or 2) or a fasting plasma glucose of
>125 mg/dl

- Have elevated bad cholesterol (greater than or equal to 190mg/dl) or triglycerides
(great than or equal to 300) and are not under the care of a physician to treat the
condition or fail to provide written documentation from your physician indicating
that the physician approves of you entering the study

- Are currently taking medications for diabetes or chronic steroid use

- Have chronic or recurrent respiratory, gastrointestinal, neuromuscular, neurological
or psychiatric conditions

- Have had cancer requiring treatment in the past 5 years, expect for non-melanoma skin
cancers or cancers that have clearly been cured or in the option of the investigator
carry an excellent prognosis (e.g., Stage 1 cervical cancer)

- Have autoimmune or collagen vascular diseases

- Have immunodeficiency diseases or HIV

- You have any other medical, psychiatric, or behavioral factors that in the judgment
of the Principal Investigator are life-threatening or that may interfere with study
participation or the ability to follow the intervention protocol.
