Interrupting\nprolonged sitting with low-intensity activity has been shown to not\nalter hunger, satiety, or food consumption in children, however it is\nunclear whether interrupting sitting with high-intensity activity will\nalter appetite regulation in children.\nPurpose\nThe purpose of this study was to examine the acute effects of\ninterrupting prolonged sitting with intermittent activity performed at\nvarying intensities on hunger, satiety, prospective food consumption\n(PFC), and food intake in preadolescent children.\nMethods\nThirty-nine children (ages 7-11 years, 54% female, 33%\noverweight/obese) completed four experimental conditions in random\norder: 8 hours of sitting interrupted with 20, 2-minute low-, moderate-,\nor high-intensity activity breaks or 20, 2-minute sedentary screen time\nbreaks. Exercise intensity corresponded with 25%, 50% and 75% of\nheart rate reserve, respectively. Hunger, satiety, and PFC were assessed\nusing the Visual Analog Scale, at five time points (pre-and\npost-breakfast, pre-and post-lunch, and pre-dinner) during each\nexperimental condition. Dietary compensation was assessed as total\ncaloric intake during a post-condition dinner standardized to provide\n70% of estimated daily energy requirements.\nResults\nThere was a significant effect of time on hunger, satiety, and PFC\nthroughout each condition day (p<0.001). There were no differences\nacross conditions for hunger (sedentary: 4.9 +/- 0.3 cm, low: 5.0 +/-\n0.3 cm, moderate: 5.1 +/- 0.3 cm, high: 5.1 +/- 0.3 cm, p>0.05), satiety\n(sedentary: 4.7 +/- 0.3 cm, low: 4.4 +/- 0.3 cm, moderate: 4.6 +/- 0.3\ncm, high: 4.2 +/- 0.3 cm, p> 0.05),and PFC (sedentary: 4.9 +/- 0.3 cm,\nlow: 4.7 +/- 0.3 cm, moderate: 4.9 +/- 0.3 cm, high: 5.0 +/- 0.3 cm, p>\n0.05). There were no significant differences in post-activity food\nintake across conditions (sedentary: 1071.9 +/- 53.6 kcals; low: 1092.6\n+/- 43.4kcals; moderate: 996.2 +/- 54.6kcals; high: 1138.7 +/- 62.8\nkcals, p> 0.05). However, there was a significant effect of condition on\nenergy balance (sedentary: + 61.4 +/- 65.9 kcals, low: + 74.9 +/- 57.6\nkcals, moderate: -58.3 +/- 62.8 kcals, high: -391.2 +/- 77.9 kcals;\np<0.001). There were no significant effects of weight status on hunger,\nsatiety, PFC, post-activity food intake, and mean energy balance across\nconditions (all p's>0.05).\nConclusions\nInterrupting prolonged sitting with physical activity of any intensity\ndoes not alter appetite sensations and subsequent food consumption in\nchildren. These data suggest that interventions targeting prolonged\nsitting with high-intensity intermittent activity may be an effective\nstrategy to increase physical activity energy expenditure without\nincreasing food intake, allowing for a short-term energy deficit in both\nhealthy weight and overweight/obese children. Future studies should\nexamine the long-term effects of interrupting prolonged sitting with\nactivity on food consumption and weight status in preadolescent\nchildren.", "link"=>"http://www.mendeley.com/research/effects-interrupting-prolonged-sitting-intermittent-activity-appetite-sensations-subsequent-food-int", "reader_count"=>10, "reader_count_by_academic_status"=>{"Professor > Associate Professor"=>1, "Student > Doctoral Student"=>1, "Student > Ph.
