• 1 other identifier: 005-8242-01
• Study Type: interventional

Brief Summary

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.

Conditions

Cardiovascular Risk Factor; Blood Pressure; Exercise; Diet Modification; Health Promotion

Keywords

Cardiovascular Disease; Mediterranean Diet; Exercise Training; Blood Pressure

Outcome Measures

Primary Outcomes (1)

• Change in blood pressure

  Blood pressure surge response to alarm will be measured by ambulatory blood pressure monitor

  Pre-Intervention (Week 0), Post-Intervention (Week 6)

Secondary Outcomes (5)

• Change in vascular stiffness

  Pre-Intervention (Week 0), Post-Intervention (Week 6)

• Change in cardiopulmonary fitness

  Pre-Intervention (Week 0), Post-Intervention (Week 6)

• Change in body composition

  Pre-Intervention (Week 0), Post-Intervention (Week 6)

• Change in inflammation

  Pre-Intervention (Week 0), Post-Intervention (Week 6)

• Change in oxidative stress

  Pre-Intervention (Week 0), Post-Intervention (Week 6)
