Study Demonstrates Exercise Improves Functionality of Aging Hearts


Based in Staten Island, New York, Hassam Khan serves in the role of director at a health food business located in Queen’s and at a bagel and gourmet deli company operating in Staten Island. Aside from his professional responsibilities, Hassam Khan maintains an interest in activities including boxing, basketball, football, baseball, soccer, and weightlifting.

According to a two-year research study conducted by cardiologists at UT Southwestern Medical Center and Texas Health Resources, exercise helps to reduce the risk of future heart failure and can also reverse damage that has already occurred in aging, sedentary hearts. Researchers recruited 53 participants ranging from ages 45 to 64. Half of the participants began the study by performing three, 30-minute, moderate intensity exercises routines weekly over three months before two intense aerobic intervals were added. The other half of the participants formed the control group, which participated in yoga and balance training.

Upon completion of the study, participants in the exercise group demonstrated more than a 25 percent improvement in left ventricular heart muscle function, which is associated with preventing heart failure, and an 18 percent improvement in maximum oxygen intake during exercise. Researchers concluded that exercise must be performed four to five times each week for maximum benefit and should be begun before the age of 65, while the heart retains remodeling capabilities.
