Aktiv komparator: Glukose
Denne studiedag vil vare cirka tre timer og vil være adskilt fra de andre arme med fire dage for mænd og en måned for kvinder.
|
Efter baseline-målinger vil deltagerne indtage en 75 g glucoseopløsning inden for fem minutter.
|
|
Eksperimentel: Glukose med fedtfri mælk
Denne studiedag vil vare cirka tre timer og vil være adskilt fra de andre arme med fire dage for mænd og en måned for kvinder.
|
Efter baseline-målinger vil deltagerne indtage 75 g glucose opløst i to kopper fedtfri mælk inden for fem minutter.
|
|
Eksperimentel: Glucose with Whey Protein Isolate
This study day will last approximately three hours and will be separated from the other arms by four days for men and one month for women.
|
Following baseline measurements, participants will consume 75 g glucose and whey protein isolate dissolved in 2 cups water within five minutes.
|
|
Eksperimentel: Glucose with Sodium Caseinate
