Resting Metabolic Rate
Délai: 32 hours
|
Metabolic rate from 11 pm on day 2 until 7 am on the morning of day 4 will be measured in a metabolic chamber.
The metabolic chamber is an air-tight room (22,000 l volume) equipped with a bed, chair, desk, television, VCR, telephone, treadmill, sink and toilet.
All meals and snacks will be served at the scheduled time.
Subjects will be asked to perform 30 min of light physical activity at 1500 h and 2030 h.
Physical activity will consist of 30 min of cycling at 12 mi/h.
Bedtimes will be the same as the previous night and actigraph monitoring will be used to confirm compliance with the sleep protocol.
Women will exit the chamber at 0700 h the following day.

Post Prandial Energy Expenditure and Thermic Effect of Food
Délai: 8 hours on day 4
|
Energy expenditure will be measured from 8 am until approximately 2:30 pm on day. Resting metabolic rate over 45 minutes will be measured at 8 am, followed by breakfast and resumption of energy expenditure measurements postprandially. Participants will be given 15 min to consume a high-fat breakfast (50% of energy from fat) and post-prandial thermogenesis and substrate oxidation will be measured for the next 6 h. |
8 hours on day 4
