PURPOSE We intended to determine predictor variables of anthropometry and training for marathon race time in recreational female runners in order to predict marathon race time for future novice female runners. METHODS Anthropometric characteristics such as body mass, body height, body mass index, circumferences of limbs, thicknesses of skin-folds and body fat as well as training variables suc...

An outstanding unresolved issue in chronobiology is how the level of locomotor activity influences length of the free-running, endogenous circadian period (tau). To address this issue, the authors studied a novel model, 4 replicate lines of laboratory house mice (Mus domesticus) that had been selectively bred for high wheel-running activity (S) and their 4 unselected control (C) lines. Previous...

PURPOSE Previous literature has presented pacing data of groups of competition finalists. The aim of this study was to analyze the pacing patterns displayed by medalists and nonmedalists in international competitive 400-m swimming and 1500-m running finals. METHODS Split times were collected from 48 swimming finalists (four 100-m laps) and 60 running finalists (4 laps) in international compet...

For the safety problem of heavy duty vehicles running on long downhill sections, a model was built for the application of engine brake and service brake combination based on test results. And a model of brake temperature rise for heavy duty vehicles running on long downhill sections was also established. For different braking modes, gear positions, speed and downhill slopes, brake temperature r...

Bending, in addition to compression, is recognized to be a common loading pattern in long bones in animals. However, due to the technical difficulty of measuring bone deformation in humans, our current understanding of bone loading patterns in humans is very limited. In the present study, we hypothesized that bending and torsion are important loading regimes in the human tibia. In vivo tibia se...

the study deals with noise problems associated with the use of air-turbine drills in dental practice. noise level measurements were made on various types of dental handpieces, when operated free running and when used to cut tooth tissue. hearing acuity tests were also undertaken in 12 randomly selected dental surgeons who have been using these drills for a number of years. the results indicate ...
