Clinical Trial Summary

Blocking histamine H1/H2 receptors blunts chronic endurance training adaptations. The current study addresses a twofold research question: "What is the influence of endurance training (1) and histamine H1 and H2 signaling (2) on the gene expression in human skeletal muscle." Results from this study will yield more insights into the molecular mechanisms of adaptations to exercise training.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in muscle transcriptome (direct response)	RNA-sequencing	On each test-day: 0 minutes after the exercise training versus at rest.
Primary	Change in muscle transcriptome (delayed response)	RNA-sequencing	On each test-day: 180 minutes after the exercise training versus at rest.
Primary	Muscle glycogen depletion	Fluorometric determination of muscle glycogen levels	On each test-day: 0 minutes after the exercise training versus at rest.
Primary	Muscle glycogen resynthesis	Fluorometric determination of muscle glycogen levels	On each test-day: 180 minutes after the exercise training versus at rest.
Primary	Plasma volume change	Plasma volume based on hemoglobin and hematocrit concentration.	Change from rest to different time-points after exercise (0, 30, 60, 120 and 180 minutes after the exercise training).
Secondary	Heart rate during the exercise training	Heart rate during the exercise training.	Continuously during training on each test-day.
Secondary	Blood lactate	Capillary lactate concentration.	On each test-day at 10 time-points: at rest, during exercise and 0, 30, 60, 120 and 180 minutes after the exercise training.
Secondary	Blood glucose	Capillary glucose concentration.	On each test-day at 10 time-points: at rest, during exercise and 0, 30, 60, 120 and 180 minutes after the exercise training.
Secondary	Blood histamine	histamine concentration in blood samples.	On each test-day at 6 time-points: at rest and 0, 30, 60, 120 and 180 minutes after the exercise training.
Secondary	Blood insulin	insulin concentration in blood samples.	On each test-day at 6 time-points: at rest and 0, 30, 60, 120 and 180 minutes after the exercise training.
Secondary	Muscle signaling pathways relevant for glucose metabolism and cardiovascular health	Phosphorylation status of proteins assessed by Western Blotting	On each test-day: at rest, 0 minutes and 180 minutes after the exercise training.
