Clinical Trial Summary

This study is investigating the presence of a soluble factor released from exercising skeletal muscle that induces mast cell degranulation.


Clinical Trial Description

Exercise promotes and maintains healthy cardiovascular, musculoskeletal, and metabolic function, but the signals and mechanisms which transduce these effects are poorly understood. Histamine plays a role in some of the positive benefits of exercise. The goal of this study is to determine the factors that regulate exercise's effects on endothelial and vascular function, with a focus on histamine released from mast cells in skeletal muscle. Young, sedentary participants will perform a peak exercise test, then participate in a single one-day experiment during which the investigators will insert an intravenous catheter in an arm vein and microdialysis probes in the leg, collect dialysate from the microdialysis probe and blood from the vein, record noninvasive measures, and have the participants perform exercise with the leg with the probes in it. ;
