Using High-speed Train Induced Signal to Estimate High-Speed Train Acceleration
Journal of Physics: Conference Series, 2023 Abstract A moving high-speed train (HST) stimulates various seismic waves near a high-speed railroad (HSR). Thus, the HST has been treated as a combined and moving seismic source. Moreover, the speed and acceleration of HST are typical moving parameters for this HST seismic source. Certain devices, such as GPS, Doppler radar, and cameras,

The Effect of High Load Training on Psychomotor Speed [PDF]
International Journal of Sports Medicine, 2007 The purpose of the present study was to investigate whether overreached athletes show psychomotor slowness after a period of high load training. Fourteen well-trained cyclists (10 male, 4 female, mean age 25.3 [SD = 4.1] years, mean maximal oxygen consumption 65.5 [SD = 8.1] ml/kg.min) performed a maximal graded exercise test on a cycle ergometer ...
