Purpose: Everything that impairs joint proprioception system can harm joints. It has been stated that stretching exercises can change properties of the proprioceptive receptors and as a result changes the sensibility of the joints proprioception. Due to fact that static stretching has greater use between athletes, it is necessary to give useful information about the safety of these stretch...

This paper is about tracking people in real-time as they move through the non-overlapping fields of view of multiple video cameras. The paper builds upon existing methods for tracking moving objects in a single camera. The key extension is the use of a stochastic transition matrix to describe people’s observed patterns of motion both within and between fields of view. The parameters of the mode...

The purpose of this study was to compare the acute effects of static stretching on vertical jump in trained male athletes. 25 healthy male athletes (age: 20.8 ± 2.3 years) who were National league 1 and 2, basketball, volleyball and handball players participated in the study. Subjects performed a 5 minute warm up followed by each of the following three stretching conditions on separate days wit...

Vibrational sum-frequency generation (SFG) spectroscopy of interfacial water at mineral/aqueous interfaces is extended to the near-IR range containing the low cross section stretch + bend combination bands (νcomb = νOH + δHOH) of liquid water at silica surfaces near 5000-5300 cm(-1), for the first time. The assignments of SFG spectra are supported by FTIR and Raman spectroscopic measurements of...

Pulsed Electron-Electron Double Resonance (PELDOR) on double-stranded DNA (ds-DNA) was used to investigate the conformational flexibility of helical DNA. Stretching, twisting, and bending flexibility of ds-DNA was determined by incorporation of two rigid nitroxide spin labels into a series of 20 base pair (bp) DNA duplexes. Orientation-selective PELDOR experiments performed at both X-band (9 GH...

TO THE EDITOR: The spectrum of reactions to my Viewpoint (3) regarding the role of the airway smooth muscle (ASM) in creating airway hyperresponsiveness akin to asthma has raised several interesting points (see Ref. 4). First, I must begin with a critical clarification. A few of the responders appear under the impression that I suggested the ASM was the “horse” we should dismount or stop chasin...
