Breathing Motion Pattern in Cyclists: Role of Inferior against Superior Thorax Compartment
We examined whether and how experience with
cycling training modifies the thoracoabdominal motion patterns. We utilized
optoelectronic plethysmography to monitor ten trained male cyclists and compared
them to ten physically active male participants performing breathing maneuvers.
Cyclists then participated in a self-paced time trial to explore the similarity
between that observed during resting breathing. From the 3D coordinates of 32
markers positioned on each participant’s trunk, we calculated the percentage of
contribution of the superior thorax, inferior thorax, and abdomen and the
correlation coefficient among these compartments. During the rest maneuvers, the
cyclists showed a thoracoabdominal motion pattern characterized by an increased
role of the inferior thorax relative to the superior thorax (26.69±5.88%,
34.93±5.03%; p=0.002, respectively), in contrast to the
control group (26.69±5.88%; 25.71±6.04%, p=0.4,
respectively). In addition, the inferior thorax showed higher coordination in
phase with the abdomen. Furthermore, the results of the time trial test
underscored the same pattern found in cyclists breathing at rest, suggesting
that the development of a permanent modification in respiratory mechanics may be
associated with cycling practice. [...] Georg Thieme Verlag Rüdigerstraße 14, 70...
