Contrasting effects in anthropometric measures of total fatness and abdominal fat mass following endurance and concurrent endurance and resistance training

摘要

An increased total fatness, and especially abdominal fat deposition, is associated with a greater risk for a variety of health problems and metabolic disturbances. It is commonly accepted that endurance training induces the greatest alterations in total adiposity despite resistance training possibly having other advantages on body fat distribution. Thirty-seven males were assigned to 16 weeks of endurance training (ET) (N=12), concurrent endurance and resistance training (CT) (N=13) or no exercise (N=12) to compare the effects of these modes of training on anthropometric measures of fat distribution in previously sedentary males on an Ad Libitum diet. The ET significantly (P≤O.05) reduced body mass by 3%, fat mass (FM) by 27%, sum of skinfolds (∑SF) by 20%, percentage body fat (%BF) by 31%, Body Mass Index by 3%, waist circumference (WC) by 2% and waist to stature ratio (WSR) by 2%. While CT significantly (P≤0.05) decreased FM by 32 %, 2SF by 20 % and %BF by 30%, it more importantly significantly reduced the majority of measures of abdominal fat mass, P≤O.05 (i.e. conic-ity index by 3%, WC by 3% and WSR by 4%). While the ET group significantly decreased their daily fat intake by 18% (P≤0.05), the CT group decreased their daily intakes of energy kilocalories by 30%, carbohydrate by 27%, protein by 29% and fat by 35 % (P≤0.05). ET was more effective at reducing total fatness, while CT preferentially reduced abdominal adipose tissue.
