Vivo Prediabetes Study: Online, Live, and Interactive Strength Training for Older Adults With Prediabetes

Eric Levian28 enrolled

Overview

This research trial studies the effect of an online, live and interactive strength training program on physical function and strength in older adults with prediabetes.

It is well established that in-person resistance training is an effective form of exercise to increase physical function and quality of life amongst adults. However, older adults report not participating in resistance training due to lack of age appropriate programs, fear of a gym setting, poor access to a gym, joint and other kinds of pain, and lack of social support. These barriers have been compounded as a result of COVID-19 pandemic, wherein older adults are encouraged to socially isolate, leading to even less physical activity. Vivo is a virtual small group exercise program designed for adults 55 and addresses these major barriers to strength training by coaching through an interactive online training session incorporating social support and social engagement. The investigators plan is to test a highly attractive technology platform specifically designed to meet the needs of older adults to demonstrate that resistance training exercise can be scaled and effective with diverse older adults and remove the barrier of having to go to a gym setting to see benefits. The investigators will test feasibility in a real world sample of adults ≥60 with prediabetes, a very prevalent, serious and often silent health condition that affects 1 in 3 adults in the US and is associated with high rates of sarcopenia, or loss of muscle mass. In the next study, Phase II NCT06458530, investigators will examine the effects of Vivo on physical function and glycemic level in sedentary older with prediabetes

Outcomes

Primary Outcomes

Leg Strength Assessed Through a 30 Second Chair Rise Test

Participants completed as many chair stands as they could in 30 seconds

Time frame: at 3 months (endpoint)

Workout Attendance

Attendance to each workout session was tallied. A possible 24 workout sessions were offered for the intervention (12 weeks of 2 days a week for workouts). The number of participants includes everyone who completed intervention, excluding those who stopped intervention at some point. The data reported represents the overall percent attendance of the participants that completed the intervention (N=22 participants). Attendance was calculated by averaging the number of sessions attended divided by the total number of exercise sessions attended (24 sessions).

Time frame: after each workout session for up to 3 months (endpoint)

Intervention Engagement Assessed by Self- Reported Ease of Use

Participants completed a questionnaire (Likert Scale) on their experience using Vivo. 1= Strong Disagree to 5= Strongly Agree

Time frame: at 3 months (endpoint)

Program Satisfaction

Participants completed the question on a questionnaire to answer "What was your overall satisfaction with Vivo?" Responses are percentage of participant who reported being satisfied or very satisfied with the Vivo intervention. A higher number indicates higher satisfaction.

Time frame: at the 3 month (endpoint)

Exercise Intervention Trainer Fidelity Checklist

The exercise intervention fidelity as assessed at 4 time points over the course of the 12-week exercise program using a 9-item checklist to ensure unbiased assessment. The purpose was to observe the exercise session to see if the main areas of the intervention were being delivered; workout intensity, safety, and participation and engagement. The results below indicate the percentage of exercise workouts that met the 9-item checklist. A higher score indicates higher fidelity.
