In order to further compare shod versus barefoot running, 35 subjects ran two bouts of 4 minutes at 3.33 m x s(-1) on a treadmill dynamometer. Parameters were measured on about 60 consecutive steps. Barefoot showed mainly lower contact and flight time (p < 0.05), lower passive peak (1.48 versus 1.70 body weight, p < 0.05), higher braking and pushing(More)
When mechanical parameters of running are measured, runners have to be accustomed to testing conditions. Nevertheless, habituated runners could still show slight evolutions of their patterns at the beginning of each new running bout. This study investigated runners' stiffness adjustments during shoe and barefoot running and stiffness evolutions of shoes.(More)
Neuromuscular control in functional situations and possible impairments due to Achilles tendinopathy are not well understood. Thirty controls (CO) and 30 runners with Achilles tendinopathy (AT) were tested on a treadmill at 3.33 ms(-1) (12 km h(-1)). Neuromuscular activity of the lower leg (tibialis anterior, peroneal, and gastrocnemius muscle) was measured(More)

The 3H-3He age of a water mass is a measure of the time that has passed since the water mass was last in contact with the afinosphere. Between 1992 and 1995 a detailed study of3H-3He ages was conducted in Lake BaikaI, the deepest and largest lake by volume on Earth, to investigate deep water renewal in its three major basins. Maximum 3H-3He ages are 14-17(More)
Foot morphology and function has received increasing attention from both biomechanics researchers and footwear manufacturers. In this study, 168 habitually unshod runners (90 males whose age, weight & height were 23±2.4 years, 66±7.1 kg & 1.68±0.13 m and 78 females whose age, weight & height were 22±1.8 years, 55±4.7 kg & 1.6±0.11 m) (Indians) and 196 shod(More)
INTRODUCTION Gait speed is one of the most commonly and frequently used parameters to evaluate gait development. It is characterized by high variability when comparing different steps in children. The objective of this study was to determine intra-individual gait speed variability in children. METHODS Gait speed measurements (6-10 trials across a 3m(More)
BACKGROUND Racing drivers require multifaceted cognitive and physical abilities in a multitasking situation. A knowledge of their physical capacities may help to improve fitness and performance. OBJECTIVE To compare reaction time, stability performance capacity, and strength performance capacity of élite racing drivers with those of age-matched,(More)
A motivation for the design of a novel hardware platform for processing algorithms based on High-Level Petri Nets is presented. ALPiNe (Asynchronous High-Level Petri Net) processor is aimed at embedded discrete-event control applications and is characterized by its natural incorporation of external stimuli into the computation flow. The processor consists(More)
Because of an increasingly older population structure and the enhanced relevance of body composition, the prevention of problems arising from the musculoskeletal system has become of central importance. Strengthening and muscle-building training have been proven to be useful even for older people. The training is focused on the types of movement and(More)
The aim of this study was to acquire static and dynamic foot geometry and loading in childhood, and to establish data for age groups of a population of 1-13 year old infants and children. A total of 10,382 children were recruited and 7788 children (48% males and 52% females) were finally included into the data analysis. For static foot geometry foot length(More)
