Fitness Programming/Assessment Article Critique I compared two articles related to whether or not aerobic exercise is the best exercise for weight and fat loss. Both articles state that if you want to lose weight and burn fat, aerobic exercise would be preferred. However, there is mixed evidence related to whether one type of exercise will be best for every health benefit. Article number one (Doheny, 2012) assigned 234 middle-aged men and women, all overweight or obese, to one of three groups (resistance-training, aerobic or combination group) for a study conducted over eight months. (1) The resistance-training group worked out three times a week, with instructions to exercise about three hours total. They used eight different weight machines. (2) The aerobic group put in about 12 miles a week on elliptical machines or treadmills, putting in about 133 minutes a week, or about 2 1/4 hours.(3) The combination group worked out three days a week, putting in the combined effort of the resistance training and the aerobic groups. 119 participants finished the study. Those who did aerobic exercise or the combination reduced total body mass and fat mass more than those in the resistance group. The article concluded that resistance training increased lean mass but did not change body weight. Also, one should focus on aerobic exercise if a person wants to lose body fat. The second article (Halvorson, 2013) conducted a study including data from 119 sedentary individuals, aged18-70. They were all overweight or moderately obese. Researchers organized the participants into three groups: (1) resistance training, (2) aerobic training and (3) RT/AT combination. The resistance training group (1) met three times per week and completed 1 set of 8-12 repetitions during weeks 1 and 2; 2 sets of 8-12 reps during weeks 3 and 4; and 3 sets of 8-12 reps during week 5.
