The guidelines forcardiovascular exercise intensity are not clear with respect to the optimaltraining protocols to reduce cardiovascular disease risk CVD as well as toenhance strength. At this time, it is impossible to deduce the independenteffects of vigorous-intensity exercise from past studies as the volume ofeither physical activity duration or energy expended differed in comparison tomoderate-intensity exercise. Our goal was to augment the literature focused onthe potential benefits of high intensity training with novel methodology thatincludes trained adults in a group fitness environment. Vigorous intensitytraining may be a critical component of the physical activity prescription ifactive adults demonstrate decreases in CVD risk factors and increases instrength. We hypothesize that a 6-week high intensity group fitnessintervention will produce beneficial effects on CVD risk factors by reducingbody mass, total cholesterol, LDL-C, triglyceride concentration, and byenhancing lean body mass percentage, HDL-C, glucose tolerance, and maximaloxygen consumption as well as both upper and lower body strength. Eighty-fourhealthy adults, 50 women and 34 men, completed the 6-week intervention. Participantswere randomly assigned to one of two groups; the first was a high intensityinterval-training GRIT program, while the second was a moderateintensity-training FIT program. All participants completed 5 hours of fitnessclasses per week. We collected musculoskeletal and physiological data at thestart and finish of the study. In support of our hypotheses, the GRIT groupsignificantly reduced body mass, triglyceride concentration and enhanced leanbody percentage, glucose tolerance, and maximal oxygen consumption in additionto all of the strength measures. These results illustrate a novel finding thatindividuals who already participate in the recommended physical activityguidelines can improve their health, fitness and strength with the addition of2, 30-minute sessions of high intensity interval training per week.
