“…Increases in energy expenditure (EE), due to exercise, can create a negative energy balance that leads to a reduction in body fat (Segal and Pi-Suyner, 1989;Bouchard et al, 1993). Substantial weight losses can occur with exercise alone (Gwinup, 1975;Slentz et al, 2004), with a dose-response relationship observed between the amount of weekly exercise and the amount of weight change (Slentz et al, 2004). However, the results of exercise trials are frequently disappointing, with participants undertaking marathon training not achieving the theoretical weight loss associated with the large increase in EE (Westerterp et al, 1992).…”

Objective: This study examines the impact of a short-term exercise programme, prescribed on the basis of current exercise recommendations, on energy balance in males and females to assess whether this type of exercise induces compensatory changes in spontaneous activity energy expenditure (SAEE) and energy intake (EI). Design: Individuals were monitored for 16 days, 8 days of habitual physical activity (C) and 8 days when exercise was imposed (E). Total energy expenditure (TEE) was calculated from individual relationships of V O 2 and V CO 2 to heart rate (HR) records of HR and physical activity obtained during waking hours of the C and E periods and basal metabolic rate (BMR) measurements (Deltatrac System, Datex Instrumentation). Changes in nude body mass (BM) were estimated by using a digital scale (Sartorius AG, Gottigen, Germany). Setting: Laboratory and free-living. Subjects: Eight lean females (body fat: 17.574.5%) and eight males of similar percentage body fat participated in this study. All subjects were Caucasian and aged between 20 and 25 years. Intervention: During the E period, a supervised exercise session was conducted every second day, each consisting of a total net energy expenditure of 2092 kJ þ BMR at 90% lactate threshold. Results: During the E period, TEE was higher than C in males and females (exercise: 95.2713.9, 78.3715.9 MJ; control: 82.4710.4, 68.8716.7 MJ, respectively; Po0.00; P ¼ 0.02). SAEE, calculated as TEE minus the energy expended during exercise, was not significantly different between C (males: 82.474.8 MJ; females: 68.877.6 MJ) and E (males: 86.876.3 MJ; females: 70.077.2 MJ) periods in either gender. Males showed no change in BM over the C (pre-intervention: 83.477.2 kg; post-intervention: 83.176.8 kg) or E (pre-intervention: 83.476.8 kg; post-intervention: 83.476.8 kg) periods. Females' BM over the C period did not alter (pre-intervention: 63.372.8 kg; post-intervention 63.773.1 kg); however, there was a significant decrease (Po0.00) in BM over the E period (pre-intervention: 63.072.7 kg; post-intervention: 62.472.7 kg). Conclusion: The exercise programme was achieved in males and females without any impact on SAEE. Therefore, differences between genders in relation to BM reduction can be explained by differences in the EI response to exercise.

“…O peso total e o peso de gordura são geralmente reduzidos através de programas de treinamento de endurance 81 , enquanto que o peso magro permanece inalterado [81][82][83][84][85] ou aumenta discretamente 58,75,86 . Para reduzir o peso corporal e o peso de gordura, têm sido sugeridos programas de exercícios com uma freqüência de pelo menos três vezes por semana 84,85,[87][88][89] , uma duração de pelo menos 20 minutos 84,85,90 e uma combinação de intensidade e duração suficientes para promover um gasto calórico de pelo menos 300kcal por sessão de exercício 81,84,91,92 . O aumento do gasto calórico acima de 300kcal por sessão e o aumento da freqüência das sessões otimizará o aumento do peso corporal e manterá o tecido magro 75,83 .…”
