An interventional study of Circuit Training exercise & Modified Mediterranean diet in Cardiovascular Risk Factor, Blood Pressure and Exercise, sponsored by University of New Hampshire. Completed at 1 site in United States. Open to participants aged 18 Years to 70 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-08-07.
Sponsored by University of New Hampshire · Not applicable, Interventional, and Prevention
The study will explore the capacity for a lifestyle modification in firefighters to improve blood pressure, blood vessel stiffness, inflammation, and reduce oxidative stress. The study will be a pre- post-testing controlled trial with three groups. The intervention will be a weekly circuit workout program and a Mediterranean (high fruit/vegetable) diet. The groups will be firefighters with >10yrs experience, firefighters with \<10yrs experience, and control Non-firefighters.
Recent statistics from the American Heart Association (AHA) have reported that >92% of adults in the U.S. meet at least 1 metric for cardiovascular disease risk factors. In firefighters, this increased risk is especially concerning. The National Fire Protection Agency (NFPA) estimates there are around 1.3 million firefighters in the United States, 70% of which are volunteer. The prevalence of impaired cardiovascular health is higher in firefighters than in the general population and the leading line-of-duty death (LODD) cause is cardiac related. It is known that exercise and diet mitigate cardiovascular disease risk. Meeting the physical activity guidelines remains a target of ideal cardiovascular health and a major public health concern. However, the NFPA does not require volunteer fire companies to have a fitness program for their crew, and sadly less than a third of the stations actually do. And importantly, cardiovascular-related LODD remains a major issue in the firefighter population. The results could guide clinical treatment for firefighters and may therefore reduce cardiac-related LODD.

Ran from Nov 2018 to primary completion in May 2023, 53 months.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 53 months is above that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
