Can cycling performance in an early morning, laboratory-based cycle time-trial be improved by morning exercise the day before?

abstract：:Excessive and prolonged exposure to impact acceleration during running is associated with increased injury rate. Acute use of compressive garments has been speculated to improve attenuation. However, it is unknown how longer interventions of compressive garments influence attenuation in running. 40 runners trained wit...
