“…32 Exercise not only increases total energy expenditure due to the extra energy expended during the exercise but also due to an elevated postexercise energy expenditure. Some studies have shown that HI exercise has a more pronounced effect on postexercise energy expenditure compared to LI exercise, [13][14][15] whereas other found no difference. 16,17 However, these studies only measured energy expenditure for several hours after the exercise bout.…”

OBJECTIVE: Exercise has been proposed as a tool for the prevention of obesity. Apart from an effect on energy expenditure, in particular low-intensity (LI) exercise might also influence substrate metabolism in favour of fat oxidation. It is however unclear what is the most beneficial exercise regime for obese people. We therefore studied the effect of either high-intensity (HI) or LI exercise on 24 h energy expenditure (24 h EE) and substrate metabolism. METHODS: Eight healthy obese male volunteers (age: 3871 y, BMI: 3171 kg/m 2 , W max : 235716 W) stayed in the respiration chamber for two nights and the day in-between. In the chamber they cycled either at a HI (three times 30 min in a interval protocol (2.5 min 80/50% W max )) or LI (three times 60 min continuously at 38% W max ) protocol with an equicaloric energy expenditure. In the chamber subjects were fed in energy balance (37/48/15% of energy as fat/carbohydrate/protein). RESULTS: The 24 h EE was not significantly different between protocols. In both protocols, sleeping metabolic rate (SMR) was elevated after the exercise (average þ 6.7%). The 24 h respiratory quotient (24 h RQ) was not different between protocols. During exercise, RQ was higher in the HI compared to the LI protocol (0.93 vs 0.91 resp., Po0.05), whereas in the postexercise period RQ tended to be lower in the HI compared to the LI protocol (P ¼ 0.06). CONCLUSION: 24 h EE is not differently affected by HI or LI exercise in obese men. Similarly, the differences in HI and LI exercise, RQ are compensated postexercise leading to similar substrate oxidation patterns over 24 h independently of the level of exercise intensity.

“…Others report an extended increase in postexercise energy expenditure after just 20 min of cycling at 70% maximum aerobic capacity (3), and differences between studies may be related to control of subject energy intake and daily activities. Several investigators emphasize that elevations in postexercise energy expenditure depend on the degree of homeostatic disturbance and that RMR is elevated especially after high-intensity long-duration exercise (6,23). For example, rates for postexercise energy expenditure were elevated for 0.3, 3.3, and 10.5 h in six males cycling for 80 min at 29%, 50%, and 75% of maximum aerobic capacity (4).…”

In young male subjects, vigorous exercise for 45 min resulted in a significant elevation in postexercise energy expenditure that persisted for 14 h. The 190 kcal expended after exercise above resting levels represented an additional 37% to the net energy expended during the 45-min cycling bout. The magnitude and duration of increased energy expenditure after a 45-min bout of vigorous exercise may have implications for weight loss and management.

“…Alguns autores têm reportado que o gasto energético após um exercício de alta intensidade é superior ao observado em outro de baixa intensidade 2,3 . Tem sido relatado também que, além de levarem ao aumento do consumo de oxigênio, os exercícios de alta intensidade favorecem o aumento da oxidação de gordura, efeito este benéfico para o controle de peso e do teor de gordura corporal 4 .…”

ÍNDICE GLICÊMICO E METABOLISMO ENERGÉTICO | 947Rev. Nutr., Campinas, 23 (6) Rev. Nutr., Campinas, 23(6):947-958, nov./dez., 2010 Revista de Nutrição minutos no grupo que consumiu a refeição de alto índice glicêmico antes do exercício, em relação ao da refeição de baixo índice glicêmico. Além disso, a taxa de oxidação lipídica do período pós-prandial foi inferior àquela obtida no período pós-exercício. ConclusãoOs resultados sugerem que enquanto o consumo de refeições de baixo índice glicêmico pode não exercer efeito benéfico, a realização de exercício físico pode promover maior oxidação lipídica e consequentemente afetar a redução do teor de gordura corporal.Termos de indexação: Consumo de oxigênio.

A B S T R A C T ObjectiveThe present study assessed, on 5 consecutive days, the effect of consuming meals with different glycemic indices on energy expenditure, energy substrate oxidation and excessive oxygen consumption after exercise. Methods A total of ResultsThe study treatments did not affect energy expenditure, excessive oxygen consumption or fat oxidation after exercise. However, the rate of fat oxidation in the 90 minutes that followed the meal was higher in those who consumed the high-glycemic index meal than in those who consumed the low-glycemic index meal. Moreover, the postprandial fat oxidation rate was lower than that observed after the exercise. ConclusionThese results suggest that, while the consumption of low-glycemic index meals may not have beneficial effects, exercise can promote greater fat oxidation and, consequently, reduce body fat.

Postexercise energy expenditure and substrate oxidation in young women resulting from exercise bouts of different intensity.

Abstract: These data indicate that the recovery period should also be considered when determining the impact of different exercise intensities on total energy expenditure and fat and carbohydrate utilization in women.
