This week is National CPR and AED Awareness Week. Be prepared with CPR and AED education. You can even get certified online at www.cprcare.com #cpr #stopheartdisease #floridaheart (fb)

A 2-year randomized study found that high-intensity exercise in previously sedentary 50-year-olds reversed cardiac aging by up to 20 years. The intervention improved cardiac elasticity, baroreflex function, and VO₂ max, demonstrating the potential for structured exercise to restore cardiovascular health. The study: - 61 middle-aged adults (avg. age 53 years) - 4-5 sessions per week, including: * 2 HIIT sessions. 4-minute intervals (on a treadmill) at 90-95% max HR * 2 moderate-intensity endurance sessions. 60 min at 70-75% max HR * 1 strength training session per week -Control Group: Low-intensity stretching, balance, and strength training 3x/week Findings: * VO₂ max increased significantly, improving overall cardiovascular function * Cardiovascular efficiency improved 1.34x compared to baseline * Baroreflex sensitivity improved * Heart structure became more elastic, reducing age-related stiffness Limitations *Study focused on healthy, middle-aged adults—results may differ in clinical populations. *Nutritional intake was not standardized, which may have influenced adaptations. Structured high-intensity exercise doesn’t just improve fitness—it can reverse cardiovascular aging and restore heart function. #heartresearch #floridaheart (fb)
