Muscle deoxygenation as a determinant of static back muscle endurance.

Muscle deoxygenation as a determinant of static back muscle endurance. - 94 p.

Adviser: Michele Crittes Battie.

Thesis (M.Sc.)--University of Alberta (Canada), 2002.

This study examined the relationships between absolute holding time on the Sorensen test and six physiological variables that might be implicated in muscle fatigue: initial magnitude and rate of deoxygenation, change in tissue oxygenation and blood volume from baseline to test termination and magnitude of initial drop in blood volume and maximum increase in blood volume following the initial drop from baseline. Subjects were 36 normal healthy males, without low back pain, completed one test session during which oxygenation and blood volume trends of the right erector spinae muscle were measured using Near Infrared Spectroscopy.

520 $a This is the first study that has analyzed muscle deoxygenation and blood volume changes during maximum voluntary isometric contraction in Sorensen test performance. The majority of the subjects (n = 27) demonstrated a decline in the level of tissue oxygenation at the start of the test, which was accompanied by an initial decline followed by an increase in the blood volume to the statically contracting muscle. However, low pearson's correlation coefficients (r = 0.005–0.09) revealed changes in tissue oxygenation and blood volume (measured by NIRS) to be poor determinants of absolute holding time on the Sorensen test. Increasing skin fold thickness resulted in greater magnitude of initial deoxygenation and lesser holding time. This study raises questions about the role of muscle fatigue in Sorensen test performance.
