Perturbations of respiratory locomotor entrainment in experienced runners: the influence of vocalization and fluid ingestion.McMurray, Robert Michael 13 January 2010 (has links)
The exact mechanism underlying the coupling between breathing and locomotion is still unknown; the visceral piston theory is a putative mechanism but has gone largely untested. The study assessed the visceral piston theory by examining the effect of perturbations (vocalization and fluid ingestion) on the coupling of breathing and locomotion. 10 experienced runners performed a speed running trial (6.5 to 8.0 mph in 0.5 mph increments), followed by a vocalization trial and a fluid ingestion trial at their preferred running speed while on a treadmill. Continuous recordings of respiratory flow and single leg, tibial acceleration was acquired (500 Hz). Rating of perceived exertion for breathing (RPEB), effort (RPEE), stitch (RPES) and heart rate (HR) were also recorded during the trials. The magnitude (SIFTMAG) and timing (SIFTT) of step induced flow transients were determined, along with the breath cycle duration (BCD) and respiratory locomotor entrainment (RLE) ratios. RPEB, and HR showed an increase in all three trials, RPEE showed an increase in the speed trial and the fluid ingestion trial but not the vocalization trial. SIFTMAG had a significant increase post perturbation (vocalization and fluid ingestion). SIFTT increased significantly post fluid ingestion but not after the vocalization perturbation. RLE ratios were increased post fluid ingestion but not post vocalization perturbation, however BCD was reduced after vocalization trials. The SIFTMAG was increased as result of perturbations corresponding to respiratory flow suppression which could lead to increased respiratory load. A shift in timing after fluid ingestion is consistent with an increased mass of a visceral spring mass system. Four of ten runners experienced a stitch after fluid ingestion. These findings strongly support the visceral piston theory of RLE, and this becomes a plausible mechanism for the induction of a stitch in the side.

Computational Fluid Dynamics Analysis on the Liquid Piston Gas CompressionWong, Lak Kin 06 December 2011 (has links)
"Liquid piston gas compression utilizes a liquid to directly compress gas. The benefit of this approach is that liquid can conform to irregular compression chamber volume. The compression chamber is divided into many small little bores in order to increases the surface area to volume ratio. The heat transfer rate increases with increasing surface area to volume ratio. However, as the bore diameter becomes smaller, the viscous force increases. In order to maximize the heat transfer rate and to minimize the viscous force, computational fluid dynamics is used. ANSYS Fluent is used to simulate the liquid piston gas compression cycle. Having created the model in Fluent, different factors, including diameter, length, liquid temperature, and the acceleration are varied in order to understand how each factor affects the heat transfer and viscous energy loss. The results show that both viscous force and heat transfer rate increase as the diameter decreases. The viscous force increases and the heat transfer decreases as the length increases. Both the viscous force and heat transfer increase as the acceleration increases. The viscous force decreases as the liquid temperature increases. Results show that the highest compression efficiency of 86.4% is found with a 3mm bore radius and a short cylinder. The piston acceleration is advised to be below 0.5g in order to avoid surface instability problem."
