forward motion characterized by both feet being simultaneously off the ground surface at a point during the gait cycle (contrast with walking, where one of the feet is always in contact throughout the gait cycle); during running the lower limb adopts a more varus position, the centre of gravity follows a more vertical path, there is greater lower-limb/foot deceleration, and a need for greater shock absorption and propulsive forces than for walking Table 1

Paradoxically, we can interpret the presence of the take-off board as both a disturbing or motivational factors in the running speed.
In our population, this decline in running speed equates to a 134 second increase in the time to complete a 5 km running bout, a substantial difference for any competitive athlete.

2), the running speed during training was significantly and negatively associated with the percentage of body fat, respectively.
Run Faster Method is the guide for the runners and athletes who want to improve their running speed.
The researchers controlled for body size and evolutionary relationships, and found that the relationship between eye diameter and maximum running speed is stronger than the relationship between body mass and running speed.
Many runners are adverse to the idea of dropping mileage and replacing the lost miles with explosive strength training, but this new research reveals that such a strategy can significantly improve maximal running speed and leg muscle power, without any loss in maximal aerobic capacity.
The correlation of the variable of the number of sprint runs and the variable of maximum running speed (r=0,76) as well as the correlation of the variable of average maximum oxygen intake and covered distance in sprint run (r=0,61) indicate that players with better functional abilities are capable of doing more sprint runs.
In 2004, the South African Journal of Sports Medicine (SA J Sports Med 2004; 16(3): 26-27) published a commentary analysing Comrades marathon records by running speed rather than race time, as the race distance varies considerably from year to year and finishing times do not therefore indicate who really have run the fastest over the course.
JR train drivers were instructed to rein in the running speed of the train if the nearby wind gauge logs 90 kph or above, but the gauge recorded a maximum wind speed of only 43.
Lab tests have shown that the system signals false positives only 1 percent of the time, so researchers will now work toward increasing its running speed.
Its running speed up to 130 cartons per minute is almost 50 per cent higher than the popular SL902 and, by using some common components, excellent value for money is achieved.
