Physical Therapy Scholarly Projects
Background and Purpose. The purpose of this pilot study was to find if there was a difference in the activation and firing time of the quadriceps (vastus medialis and vastus lateralis) compared to activation times of the hamstrings (biceps femoris and semitendinosus) in active males and females.
Methods. Subjects consisted of two male and two female athletes in good physical condition with no previous knee pathologies. During each of the trials, the muscle activity of each muscle was recorded. The EMG activity recorded using a Noraxon TeleMy02400 G2 telemetry unit with a sampling rate of 1 kHz which …
