简要总结
The investigators will determine the acute effect of exercise on breastmilk composition. Participants will come in to the lab on three different days, out of which they will exercise on two of these days and rest in the lab on the third day. The conditions will be randomly allocated to each participant. Breastmilk samples will be obtained in the morning of each test day, as well as immediately after, one hour after and four hours after the exercise/rest condition. Dietary intake will be standardized on the test days.

研究组 & 干预措施
Control
Resting in seated position
Moderate intensity exercise
Moderate intensity endurance exercise, treadmill walking/running at 70% of heart rate maximum for 40 minutes
干预措施: Moderate intensity exercise (Behavioral)
High intensity exercise
High intensity interval training: treadmill walking/running. 10 minutes warm-up at 70% of heart rate maximum, followed by four 4-minutes bouts at 90-95% of heart rate maximum, separated by 3-minutes active recovery (at 70% of heart rate maximum)
干预措施: High intensity exercise (Behavioral)
