Physical exercise and normobaric hypoxia: independent modulators of peripheral cholecystokinin metabolism in man

What Was Tested

Researchers studied Cholecystokinin (CCK) in this randomized controlled trial publication.

The purpose of the present investigation was to determine the independent effects of hypoxia and physical exercise on peripheral cholecystokinin (CCK) metabolism in humans.

Why It Was Studied

Thirty-two physically active men were randomly assigned in a double-blind manner to either a normoxic (N; n = 14) or hypoxic (H; n = 18) group.

During the acute study, subjects in the H group only participated in two tests, separated by 48 h, which involved a cycling test to exhaustion in normobaric normoxia and normobaric hypoxia (inspired O(2) fraction = 0.21 and 0.16, respectively).

Who Took Part

The age groups tagged for this paper are adults, men only.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

Because people in this Cholecystokinin (CCK) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the participants and researchers unaware of who received Cholecystokinin (CCK).

What Was Measured

During the acute study, subjects in the H group only participated in two tests, separated by 48 h, which involved a cycling test to exhaustion in normobaric normoxia and normobaric hypoxia (inspired O(2) fraction = 0.21 and 0.16, respectively).
