Popis: Introduction: Previous literature shows an “appeared linear dose-response between activity levels and HDL cholesterol levels” However, long duration physical activity may decrease HDL and LDL cholesterol. Intensity may better dictate the change in cholesterol. Methods: Group 18 of My Unlimited Potential (worksite wellness program for Baptist Health South Florida Employees) performed a preprogram fitness assessment that included resting, testing, and post-test physiological values such as blood pressure and resting HR. Anthropometric measures such as height, weight, 7 and 6 site girth measurements for men and women. Percentage of body fat using Bio electric impedance. The cardiovascular assessment consisted of a V max (Velocity Max) test on the treadmill. The participants received an exercise prescription (ERX) based on the fitness assessment. Group 18 used the speed and grade of the cardiovascular portion of the fitness assessment to create an ERX. During the course of the 12 weeks V max was reassessed every 2 weeks to determine a new intensity for cardiovascular exercise. The exercise protocol during the first 12 weeks consisted of 20 minutes of interval cardiovascular training and 40 minutes of whole body gross movement resistance training two times a week. The length of each high intensity interval was determined by the participant’s own tolerance. Resistance training consisted of whole body gross movements, the use of free weights and a metabolic exercise, at the individuals ERX. Results: Independent sample t-test showed mean improvement of 3.2 points in group 18 when compared to other cohorts (Table 2). Adjusted regression analysis where dependent variable was HDL showed improvement when compared to other groups (Table 3). Discussion: With V max the intensity is given in a clear speed and incline that must be achieved irrelevant of the interval length performed during cardiovascular activity. We have had 18 total cohorts complete 12 weeks. Only group 18 had a significant increase in HDL. Only group 18 followed this protocol.
