The Effects of an Acute Bout of Aerobic or Resistance Exercise on Nonexercise Physical Activity

Abstract

Introduction/Purpose A reduction in nonexercise physical activity (NEPA) after exercise may reduce the effectiveness of exercise interventions on weight loss in adults with overweight or obesity. Aerobic exercise (AEx) and resistance exercise (REx) may have different effects on NEPA. The purpose of this secondary analysis was to examine the effect of a single bout of AEx or REx on NEPA and sedentary behavior in inactive adults with overweight or obesity. Methods Adults with overweight or obesity (n = 24; 50% male; age, 34.5 ± 1.5 yr; body mass index, 28.5 ± 0.9 kg·m−2) not meeting current physical activity guidelines completed a single 45-min bout of AEx, REx, or a sedentary control on different days in random order. After each condition, participants’ NEPA was recorded for 84 h by accelerometer. Time spent sedentary and in light, moderate, and vigorous physical activity; steps; metabolic equivalent of task (MET)-hours; and sit-to-stand transitions were calculated using activity count data. Results No differences were observed in the percent of waking time spent sedentary and in light, moderate, and vigorous activity between conditions (P > 0.05). No differences were observed in steps, MET-hours, or sit-to-stand transitions between conditions (P > 0.05). NEPA responses were variable among individuals, with approximately half of participants reducing and half increasing NEPA over the 84 h after each exercise condition. Conclusion NEPA was not reduced after an acute bout of AEx or REx in a sample of inactive adults with overweight or obesity.

Differences in Associated Factors of Sedentary Behavior by Diabetes Mellitus Status: A Nationwide Cross-Sectional Study

“…Among the various physical activity categories, such as aerobic exercise, strength exercise, flexibility training, and light walking, engaging in aerobic exercise is suggested to have behavioral and cardiorespiratory benefits [38]. Furthermore, a previous study found that engaging in aerobic or resistance exercise did not reduce non-exercise physical activity after the exercise [39].…”

Acute Vigorous Exercise Decreases Subsequent Non-Exercise Physical Activity and Body Temperature Linked to Weight Gain

“…However, human studies face difficulties in accurately and continuously detecting NEPA and core body temperature as indicators of whole-body thermogenesis after exercise (28,29). Indeed, compensatory responses in NEPA to exercise intervention often exhibit considerable variability among participants due to challenges in controlling external factors such as genetic and social background, living conditions, dietary habits, and other free-living activities (30,31). In addition, ingestible telemetric capsules are often used for the measurement of core body temperature in free-living humans (32), but accurate detection could fail owing to the influence of some foods/drinks (29).…”
