What this study is about

Caloric restriction programmes are highly effective and safe interventions for inducing rapid weight loss and improvements in glycaemic control. The landmark DiRECT study showed that 68% of people completing a caloric restriction intervention achieved remission of type 2 diabetes (T2D) by one year. Consequently, the NHS Path to Remission (PTR) programme was developed to stimulate diabetes remission in individuals that meet certain criteria. Unfortunately, long-term follow-up of the DiRECT study suggests that in the majority of participants that achieved remission, diabetes relapses within 5 years. This necessitates a focus on identifying methods to improve long-term maintenance of diabetes remission. High-intensity interval training (HIIT) involves several brief bursts of intense exercise, interspersed with recovery breaks, and is becoming increasingly popular. HIIT can cause improvements in cardiovascular fitness, reduce blood pressure, and lower body fat content in only a fraction of the time of traditional exercise methods. Specific to T2D, HIIT has been shown to improve pancreatic beta cell function, which is critically important for maintenance of long-term diabetes remission. This pilot study is being conducted to determine whether participating in a home-based HIIT training programme may help maintain beta cell function in individuals that have achieved diabetes remission following the NHS PTR programme. The study will take place at the Royal Derby Hospital. The intention is to recruit 20 participants from Derbyshire or Nottinghamshire that have achieved diabetes remission in the NHS PTR programme. Participants will be recruited following discharge from the programme and allocated to either perform a HIIT training programme (intervention group), or continue with usual care (control group) for 16 weeks. Before starting, participants will attend the research department to have initial measurements taken including bioimpedance, fasting bloods, an intravenous glucose tolerance test, muscle ultrasound, electromyography and cardiopulmonary exercise testing. Following this, those in the intervention group will be asked to perform a home-based HIIT training programme 3 times per week and record details of each session in a booklet. The control group will be asked to continue with their habitual levels of physical activity. Participants will be contacted regularly to ensure their safety and compliance.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.
