Postexercise fat oxidation may be important for exercise prescription aimed at optimizing fat loss. The authors examined the effects of exercise intensity, duration, and modality on postexercise oxygen consumption (VO2) and substrate selection/respiratory-exchange ratio (RER) in healthy individuals. Three experiments (n = 7 for each) compared (a) short- (SD) vs. long-duration (LD) ergometer cycling exercise (30 min vs. 90 min) matched for intensity, (b) low- (LI) vs. high-intensity (HI) cycling (50% vs. 85% of VO2max) matched for energy expenditure, and (c) continuous (CON) vs. interval (INT) cycling matched for energy expenditure and mean intensity. All experiments were administered by crossover design. Altering exercise duration did not affect postexercise VO2 or RER kinetics (p > .05). However, RER was lower and fat oxidation was higher during the postexercise period in LD vs. SD (p < .05). HI vs. LI resulted in a significant increase in total postexercise energy expenditure and fat oxidation (p < .01). Altering exercise modality (CON vs. INT) did not affect postexercise VO2, RER, or fat oxidation (p > .05). These results demonstrate that postexercise energy expenditure and fat oxidation can be augmented by increasing exercise intensity, but these benefits cannot be exploited by undertaking interval exercise (1:2-min work:recovery ratio) when total energy expenditure, duration, and mean intensity remain unchanged. In spite of the apparent benefit of these strategies, the amount of fat oxidized after exercise may be inconsequential compared with that oxidized during the exercise bout.

The National Weight Control Registry (NWCR) was established to examine characteristics of successful weight loss maintainers. This study compares the diet and behavioral characteristics and weight regain trajectories of NWCR members with differing physical activity (PA) levels at baseline.


Participants (n = 3591) were divided into 4 levels of self-reported PA at registry entry (< 1000, 1000 to < 2250, 2250 to < 3500, and ≥ 3500 kcals/week). We compared self-reported energy intake (EI), macronutrient composition, eating behaviors (dietary restraint, hunger, and disinhibition), weight loss maintenance strategies, and 3 year weight regain between these 4 activity groups.


Those with the highest PA at registry entry had lost the most weight, and reported lower fat intake, more dietary restraint, and greater reliance on several specific dietary strategies to maintain weight loss. Those in the lowest PA category maintained weight loss despite low levels of PA and without greater reliance on dietary strategies. There were no differences in odds of weight regain at year 3 between PA groups.


These findings suggest that there is not a “one size fits all strategy” for successful weight loss maintenance and that weight loss maintenance may require the use of more strategies by some individuals than others.

HIFT is a popular form of exercise, there is limited research regarding HIFT 17 , 18 and it is not commonly endorsed as a mode of meeting recommended physical activity levels or for weight management. This may be partially due to lack of information in the literature regarding objectively measured

Obesity in young adults is of public health concern, given its high prevalence and potential adverse health consequences. 1 – 3 Innovative strategies are needed that are widely acceptable and effective in long-term weight management. 4 Given that some research suggests that overweight individuals

The enjoyment subscale was initially included but was ultimately omitted because it overlapped significantly with the revitalization subscale. For

Consistent with the strategies reported by male collegiate athletes ( Galli, Petrie, Reel, Greenleaf, & Carter, 2015 ), the male skaters in this study reported muscle-building behaviors, exercise, and dietary restriction as a means of attaining and maintaining the body
