概要
This study plans to learn more about metabolic responses to aerobic exercise at different times of the day (morning or evening) under fasting versus fed conditions.
詳細説明
This study plans to learn more about metabolic responses to aerobic exercise at different times of the day (morning or evening) under fasting versus fed conditions. Specifically, the investigators will explore the effect of fasted and fed AM and PM aerobic exercise on exercise energy expenditure and substrate oxidation, explore the effect of fasted and fed AM and PM aerobic exercise on plasma metabolites and lipids, and explore the effect of fasted-AM and Fasted-PM on 24h energy expenditure, 24h substrate metabolism, 24h glucose, and 24h profiles of hormonal regulators of energy metabolism

実験的TANDEM Exercise Participants in this arm will engage in morning aerobic exercise while in a fasted state, morning aerobic exercise while in a fed state, evening aerobic exercise while in a fasted state, and evening aerobic exercise while in a fed state in a randomly assigned order | Fasted-am Participants will engage in aerobic exercise within 4 hours of waking up, following a \>10h overnight fast across the 4d run-in and exercise metabolism assessment day. Energy and macronutrient-controlled meals will be consumed at \~08:00, \~13:00, and \~19:00. Plasma metabolite samples will be drawn immediately pre- and post- exercise. Fed-am Participants will engage in exercise within 4 hours of waking up, approximately 1h after consuming breakfast across the 4d run-in and exercise metabolism assessment day. Energy and macronutrient-controlled meals will be consumed at \~07:00, \~12:00, and \~18:00. Plasma metabolite samples will be drawn immediately pre- and post-exercise. Fasted-pm Participants will engage in exercise between 8-12 hours after waking up, following a \~10h fast across the 4d run-in and exercise metabolism assessment day. Energy and macronutrient-controlled meals will be consumed at \~07:00 and \~18:00. Plasma metabolite samples will be drawn immediately pre- and post-exercise. Fed-pm Participants will engage in exercise between 8-12 hours after waking up, approximately 1h after consuming dinner across the 4d run-in and exercise metabolism assessment day. Energy and macronutrient-controlled meals will be consumed at \~07:00, \~12:00, and \~18:00. Plasma metabolite samples will be drawn immediately pre- and post-exercise. |

|---|---|---|
Exercise Energy Expenditure (kcals) | On Day 5 of each condition, participants will complete a 45-minute exercise test on the treadmill to compare exercise energy expenditure and fat oxidation between. O2 and CO2 content of expired air will be measured continuously by open circuit spirometry and averaged every minute using an automated online system (TrueMax 2400; Parvo-Medics, Sandy, UT). Exercise energy expenditure will be determined from minute-by-minute values, measured in kcals. | Fasted-AM Day 5, Fed-AM Day 5, Fasted-PM Day 5, Fed-PM Day 5 |
Substrate Oxidation (Respiratory Quotient) | On Day 5 of each condition, participants will complete a 45-minute exercise test on the treadmill to compare exercise energy expenditure and fat oxidation between. O2 and CO2 content of expired air will be measured continuously by open circuit spirometry and averaged every minute using an automated online system (TrueMax 2400; Parvo-Medics, Sandy, UT). Substrate Oxidation will be determined from minute-by-minute values, measured in respiratory quotient. | Fasted-AM Day 5, Fed-AM Day 5, Fasted-PM Day 5, Fed-PM Day 5 |
