Can quadriceps EMS lift on-court power in competitive tennis players?

A Zurich team tested electrostimulation on twelve competitive tennis players. They ran nine short EMS sessions on the quadriceps across three weeks. Scientists recorded rising current, evoked force from 200 N to 800 N, and 100 percent attendance. Maximum strength climbed through week six. Countermovement jump height rose 5.3 percent then 6.4 percent. The 2 × 10 m shuttle sprint got 3.3 percent faster three weeks later. Stretch-shortening also improved. The work came from Schulthess Clinic, the University of Burgundy and an Italian academy. It appeared in the Journal of Strength and Conditioning Research. These measured gains show targeted EMS can lift tennis power and speed inside normal practice.
