In order to reverse the motor rotation direction, the motor must overcome this viscous torque M. We hypothesize that this effect results in an additional energy barrier that has to be overcome for an attempted switching event to be ultimately successful. The height of this barrier may be ...
Running economy SEA runners were significantly less economical (6%) than non-SEA runners (average across speeds: 522.6 ± 47.4 vs 492.4 ± 42.2 ml/kg0.75/km), with amoderatemain effect of group on RE (p = 0.04,d = 0.67; Fig.2). There was no significant main effe...
An opening timing of intake valves is changed thereby in a direction such to decrease an engine output torque. In another aspect of the invention control is exercised over a braking torque applied to the driving wheels of the vehicle in correspondence with a traction loss or skid detected ...
It is well-reported that MVC force/torque is impaired for several days following DR (up to 4–5 days for a complete recovery; see Fig.1). However, a better understanding of the mechanisms responsible for delayed MVC force/torque loss is warranted. Firstly, it is likely that several mechani...
Data from the sprinting gait cycle were analyzed via an intersegmental dynamics approach, and the different joint torque components were calculated.During the... Y Sun,S Wei,L Yu,... - 《Medicine & Science in Sports & Exercise》 被引量: 32发表: 2015年 Optimal control of human running Opt...
When transitioning from walking to running near the preferred transition speed (2.0 m s -1 ), greater, more economical ankle torque development is likely explained by the SO muscle fascicles shortening slower and operating on a more favorable portion (i.e. closer to the plateau) of the force...
foot–ground contact time in DR, which may lead to accentuated acute and delayed EIMD (e.g. structural muscle alterations, leakage of specific-muscle proteins into the bloodstream, reduction in MVC force/torque) [3, 38], and consequently alteration in running economy (RE) and performance [3...
Figure 1 demonstrates our methods applied to a single marathon run (subject M1) of group M. The color-coded value of the scale-dependent exponent \(\alpha (s)\) is shown in the first row as a function of the binned heart rate (HR) (Fig. 1a) and also as a function of running tim...
