TI  - The metabolic consequences of low and moderate intensity exercise with or without 
      feeding in lean and borderline obese males.
PG  - 95-104
AB  - The purpose of this study was to investigate the role of exercise intensity on 
      the post-exercise thermogenic effect (PETE), with or without feeding, in five 
      lean (less than 15 percent body fat) and five borderline obese (between 20 and 25 
      percent body fat) individuals when the total caloric expenditure during exercise 
      was equated to 720 kcal by adjusting exercise duration. Each subject participated 
      in six testing sessions, including the measurement of resting metabolic rate 
      (RMR), dietary induced thermogenesis (DIT) following a 720 kcal liquid meal, and 
      four exercise trials including: (1) exercising on a treadmill at both 30 percent 
      and 60 percent of VO2 max followed by a 720 kcal liquid meal (30F and 60F); and 
      (2) exercising on a treadmill at both 30 percent and 60 percent of VO2 max 
      followed by a non-caloric liquid meal substitute (water) matched by volume to the 
      caloric liquid meal (30NF and 60NF). Indirect calorimetry was used to determine 
      metabolic rate prior to each treatment (0-30 min RMR) and at 0-30, 50-60, 80-90, 
      110-120, 140-150, and 170-180 min following the feeding, exercise only, or 
      exercise and feeding treatments. A significant difference in the post-exercise 
      oxygen consumption was found between the two calorically equated exercise bouts 
      (720 kcal) at 30 percent and 60 percent of each subject's VO2 max without feeding 
      when all measurement periods following exercise were averaged together (60NF = 
      13.5 percent increase and 30NF = 5.5 percent). This difference was observed in 
      both the lean and borderline obese subjects, with no significant difference 
      between the two groups. In addition, when walking at either 30 percent or 60 
      percent of VO2 max preceded feeding, a significant attenuation in the rise of 
      post-feeding RER values was observed in both groups with the higher exercise 
      intensity showing the greatest RER attenuation when compared to the DIT trial. 
      These results suggest that exercise intensity may play a significant role 
      independent of the total energy expenditure in potentiating a person's 
      post-exercise oxygen consumption rate and post-exercise substrate utilization for 
      periods of up to 180 mins.
