What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how a program called Vivo can help people with prediabetes improve leg strength and manage blood sugar levels. Participants will either join virtual exercise sessions with a trainer or remain in a waitlist group, continuing their usual activities. This trial suits individuals aged 60 and up who have been diagnosed with prediabetes in the past year, are not very active, and have no recent experience with resistance training.

As an unphased study, this trial provides a unique opportunity to explore new methods for enhancing health and well-being.

Will I have to stop taking my current medications?

If you are taking antidiabetic medications or testosterone supplements, you will need to stop them to participate in this trial. The protocol does not specify about other medications.

What prior data suggests that Vivo is safe for prediabetes?

Research shows that exercise is generally safe and well-tolerated for people with prediabetes. A recent study found that exercise significantly improved blood sugar control in these individuals. Although specific safety data for Vivo, a virtual exercise program, remains limited, similar programs are usually considered safe. Participants in similar studies often complete the programs without major issues. Notably, the Vivo program includes virtual, supervised sessions, enhancing safety by providing guidance and support. Overall, evidence suggests that the Vivo program should be safe for participants. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Most treatments for prediabetes emphasize lifestyle changes like diet adjustments and increased physical activity. However, Vivo is unique because it offers a structured, virtual approach to exercise, providing participants with twice-weekly online sessions led by certified trainers. This convenience allows for personalized guidance and motivation, making it easier for individuals to stick to an active lifestyle, which is crucial for managing prediabetes. Researchers are excited about Vivo because it combines the flexibility of virtual support with the accountability and expertise of professional trainers, potentially leading to better adherence and outcomes compared to traditional methods.

What evidence suggests that Vivo might be an effective treatment for prediabetes?

Research shows that Vivo, an online strength training program, can help older adults improve physical function and strength. In this trial, some participants will engage in the Vivo intervention, meeting virtually twice a week for 12 weeks with their small group and certified trainer. Studies have found that strength exercises can help control blood sugar levels, which is important for people with prediabetes. Clinical trials have also shown that programs like Vivo can lower the risk of developing type 2 diabetes by maintaining healthy blood sugar levels. Managing blood sugar is crucial because it can prevent other health problems. Overall, evidence suggests that Vivo could effectively manage prediabetes and boost overall health. ^{1 6 7 8 9}

Published Research Related to This Trial

Prediabetes is characterized by elevated blood glucose levels that are not high enough to be classified as diabetes, indicating a state of abnormal glucose homeostasis.

Recent evidence and the inclusion of prediabetes in ICD-10 codes support the idea that it is a distinct pathological condition associated with changes in various tissues and organs, highlighting its clinical significance.

Understanding prediabetes: definition, prevalence, burden and treatment options for an emerging disease. Rett, K., Gottwald-Hostalek, U.[2020]

Prediabetes significantly increases the risk of developing type 2 diabetes and is associated with complications similar to those seen in diabetes, highlighting the importance of early intervention.

Intensive lifestyle changes and metformin have been shown to effectively prevent or delay the onset of type 2 diabetes in individuals with prediabetes, with lifestyle interventions generally being more effective, and long-term follow-ups indicate that early interventions can lead to lasting health benefits.

In a study of 48 patients with early diabetes mellitus type 2 (eDM2) and 16 with prediabetes (preDM), it was found that 14.6% of eDM2 patients had confirmed diabetic sensorimotor polyneuropathy (DSPN) based on nerve conduction studies, indicating a significant risk of neuropathy in early diabetes.

Using intraepidermal nerve fiber density (IENFD) as an additional diagnostic criterion revealed that 37.5% of eDM2 patients had DSPN, highlighting that neuropathy in preDM and eDM2 primarily affects sensory small fibers, which can be detected early with IENFD measurements.

In a study involving 44 participants (25 with normal fasting glucose and normal glucose tolerance, and 19 with normal fasting glucose but impaired glucose tolerance), insulin-stimulated glucose disposal was found to be significantly lower in those with impaired glucose tolerance, indicating a defect in insulin action.

The research concluded that the issues leading to impaired glucose tolerance are not due to defects in liver glucose production but rather due to impaired insulin action and β-cell function, highlighting the importance of insulin sensitivity in managing prediabetes.
