The body temperature, activity-rest time, electrolytes of urine samples and mood was measured in two persons a 19 day period under continuous light conditions in the arctic (vicinity of Ny Alesund, Svalbard-Spitsbergen). For temperature recording a new thermoprobe and a portable printer was used. Possible week Zeitgeber of the 24 hour day did not synchronize the circadian system, since circadia...

PLoS Biology | http://biology.plosjournals.org Epigenomics is one of the many ‘omics’ that is being talked about in the wake of the Human Genome Project. But what is an epigenome, and why have the Wellcome Trust Sanger Institute (Hinxton, United Kingdom) and Epigenomics AG (Berlin, Germany) recently announced the launch of the Human Epigenome Project (HEP), a five-year undertaking during which ...

The goal of this research was to analyze the effects of fatigue on the shock waves generated by foot strike. Twenty-two subjects were instrumented with an externally attached, lightweight accelerometer placed over the tibial tuberosity. The subjects ran on a treadmill for 30 min at a speed near their anaerobic threshold. Fatigue was established when the end-tidal CO2 pressure decreased. The res...

A high-level motion control system for the animation of human-like gures is introduced which generates a wide variety of individual running styles in real time. Sequences such as a leisurely jog, a fast sprint or a bouncy run are conveniently obtained by interactively setting the values of \running" parameters such as desired velocity, step length, \ ight" height or \heel/toe" strike while obse...

Running is an essential mode of human locomotion, during which ballistic aerial phases alternate with phases when a single foot contacts the ground. The spring-loaded inverted pendulum (SLIP) provides a starting point for modelling running, and generates ground reaction forces that resemble those of the centre of mass (CoM) of a human runner. Here, we show that while SLIP reproduces within-step...

Despite distinct differences between walking and running, the two types of human locomotion are likely to be controlled by shared pattern-generating networks. However, the differences between their kinematics and kinetics imply that corresponding muscle activations may also be quite different. We examined the differences between walking and running by recording kinematics and electromyographic ...
