The aim of this study was to investigate the effects of electrical muscle stimulation (EMS) training on hamstring muscle strength. The study utilised a quantitative experimental research design. The intervention was assessed using a Humac Norm 7000 Dynamometer. A Chattanooga Intelect Mobile Combo muscle stimulator was used for the 4-week EMS training based on the 10-50-10 or “Russian Protocol”. Descriptive statistics were performed and pre- to post-test changes were analized using dependent t-tests. Statistical significance was set at p≤0.05. Following 4-weeks’ EMS training there were statistically significant increases in both the PTQ and work performed during concentric isokinetic knee flexion at 60°/s. There was also a 21.4% increase in the H/Q ratio following the EMS training. Considering the present results and previous research conducted, both the quadriceps and hamstring muscles groups seem to be responsive to EMS strength training.
