Aryeh Spingarn Queens College, City University of New York Department of Family, Nutrition, and Exercise Sciences, Effects of an 18-week strength, conditioning, and circuit training program on weight loss in a middle-aged male. Purpose: The purpose of this study was to examine the effects of a strength, conditioning, and circuit training program on weight loss in a middle age adult. Methods: The subject participated in an 18-week strength and conditioning program 2 days per week for one hour per session, totaling 2 hours of training time per week. The first 12 weeks of the program included only strength training for both sessions, the following 6 weeks of the program was alternated between strength training and circuit training. Results: The program resulted in a reduction in Body Weight (BW), Body Mass Index (BMI), and Waist-Hip Ratio (WHR). Prior to the intervention: BW=191lbs, BMI=30.04; Class I obese, and WHR=0.98. Post intervention: BW=189lbs, BMI=29.72; overweight, and WHR=0.95. Conclusions: It appears that an 18-week program that includes both strength training and circuit training resulted in a reduction of BW, BMI, and WHR it can therefore be concluded, that this type of programing can be effective in eliciting weight loss.
