Even though exercise improves long-term weight loss maintenance and reduces the risks of cardiovascular disease and Type II diabetes mellitus, obese adults are prone to drop out of exercise programs. Dr. Jakicic's prior findings suggest that exercise adherence can be enhanced and short-term weight loss can be improved by making exercise more convenient via prescribing exercise in multiple short bouts, rather than one bout per day. Effects on long-term exercise adherence and weight loss have not been examined, however. His findings also suggest that providing more exercise options by placing exercise equipment in the home may also increase adherence, as evidenced by a significant correlation between the presence of home exercise equipment and physical activity. However, no experimental studies have tested whether placing exercise equipment in the home actually increases exercise adherence and weight loss.
The study tested the hypothesis that prescribing exercise in multiple short bouts would improve long-term exercise adherence and long-term weight loss, and that the addition of home exercise equipment would further improve these outcomes. A total of 148 overweight women were recruited and randomized to one of three treatments: 1) long-bout exercise; 2) short-bout exercise; 3) short- bout exercise + home exercise equipment. All subjects participated in an 18-month behavioral weight loss program, in which body weight was assessed at 0, 6, 12, and 18 months and exercise adherence was assessed throughout the 18 months. Cardiorespiratory fitness and cardiovascular disease risk factors were measured at 0, 6, and 18 months.

This study investigated if exercise dose affected acylated ghrelin response to exercise training, and how body weight or fat mass changes might affect the responses. Non-obese older women (n = 49)...
Weight loss from exercise is often less than expected. Putative compensatory mechanisms may limit exercise-induced reductions in body fat and might be proportional to exercise energy expenditure.
Knee osteoarthritis(KOA) has a considerable prevalence in obese individuals and recommendations of weight loss for KOA management are gaining greater importance. Exercise is recommended to interrupt t...
The circulatory level of pentraxin3 (PTX3), an anti-inflammatory cardio-protective protein, has been known to be lower in obese individuals than in those with normal weight. However, reports on the ef...
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
A cardiovascular exercise strategy with alternating short periods of intense anaerobic exercise with less-intense recovery periods.
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death.
