Exercise is widely promoted as a method of weight management, while the other health benefits are often ignored
The effectiveness of exercise should not be exclusively judged on changes in body weight because it undermines the other health benefits that are commonly associated with exercise
Despite the lower-than-expected weight loss, the non-responders did achieve improvements in health markers. They experienced a significant increase in aerobic capacity (6.3 (6.0) ml/kg/min; p,0.01), reduction in waist circumference (23.08 (2.66) cm; p,0.01), and decreases in systolic (26.0 (11.5) mm Hg; p,0.05), diastolic blood pressure (23.9 (5.8) mm Hg; p,0.01) and resting heart rate (24.8 (8.9) bpm; p,0.001)
Summary
Exercise is widely promoted as a method of weight management, while the other health benefits are often ignored. 26 of the 58 participants failed to attain the predicted weight loss estimated from individuals’ exercise-induced energy expenditure. Despite attaining a lower-than-predicted weight reduction, these individuals experienced significant increases in aerobic capacity (6.3 (6.0) ml/kg/min; p,0.01), and a decreased systolic (26.00 (11.5) mm Hg; p,0.05) and diastolic blood pressure (23.9 (5.8) mm Hg; p,0.01), waist circumference (23.7 (2.7) cm; p,0.01) and resting heart rate (24.8 (8.9) bpm, p,0.001). These individuals experienced an acute exerciseinduced increase in positive mood. From a public health perspective, exercise should be encouraged and the emphasis on weight loss reduced
