Study Details

Study Description

Brief Summary

The Initiate and Maintain Physical Activity in Clinics (IMPACT) study will determine the optimal and feasible level of frequency of structured contact needed in a clinical setting for adult patients with Type 2 Diabetes Mellitus to initiate and maintain physical activity recommendations long-term.

Condition or Disease Intervention/Treatment Phase
  • Behavioral: Structured Group Exercise
N/A

Detailed Description

The IMPACT Study will compare the health outcomes and lifestyle habits amongst the three groups of study participants. Study participants will be randomized into three exercise group. Group 1 will participate in instructor-led exercise training sessions 1 time per week, for 24 weeks (approximately 6 months). Group 2 will participate in instructor-led exercise training sessions 3 times per week, for 24 weeks (approximately 6 months). Group 3 will not attend any instructor-led exercise training sessions. All groups will be encouraged to see their usual providers for routine healthcare, and continue their usual medication regimen.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Once-Weekly Structured Contact

Participants in the Once Weekly Structured Contact group will take part in an 6-month exercise intervention and attend one structured group exercise session per week. They will engage in aerobic and resistance training for approximately 80 minutes per exercise session. Additionally, they will attend three exercise evaluations and six study visits.

Behavioral: Structured Group Exercise
The study intervention is a 6-month exercise program with structured group sessions conducted in a clinical setting. Group sessions include Aerobic Training and Combined Training. Once-Weekly participants will attend one Combined Training session while thrice-weekly participants will attend two Combined Training sessions and one Aerobic Training session per week. Participants in both groups will attend three exercise evaluations during the intervention period. Participants will also use provided logs to track their daily exercise activities outside of group sessions. Physical activity will be assessed by group session attendance, exercise resistance and intensity, and exercise frequency data collected from exercise logs, surveys, and evaluations.

Experimental: Thrice-Weekly Structured Contact

Participants in the Thrice-Weekly Structured Contact group will take part in an 6-month exercise intervention and attend three structured group exercise sessions per week. In total, they will engage in aerobic and resistance training sessions for approximately 200 minutes per week. Additionally, they will attend three exercise evaluations and six study visits.

Behavioral: Structured Group Exercise
The study intervention is a 6-month exercise program with structured group sessions conducted in a clinical setting. Group sessions include Aerobic Training and Combined Training. Once-Weekly participants will attend one Combined Training session while thrice-weekly participants will attend two Combined Training sessions and one Aerobic Training session per week. Participants in both groups will attend three exercise evaluations during the intervention period. Participants will also use provided logs to track their daily exercise activities outside of group sessions. Physical activity will be assessed by group session attendance, exercise resistance and intensity, and exercise frequency data collected from exercise logs, surveys, and evaluations.

No Intervention: Usual Care

Participants in the Usual Care group will not take part in an 6-month exercise intervention. They will continue to seek regular care from their primary care providers and attend six study visits.
