Various studies confirm you get serious results from EMS training. The American Council On Exercise recently tested developments in equipment, revealing that muscle strength and endurance are improved by those who had used an EMS device.
EMS Training and Isokinetic Muscle Contractions
The American College of Sports Medicine examined the effects of short-term EMS training on the physical performance of hockey players, specifically skating, knee extensions and vertical jump performance.
The study concluded that EMS significantly enhanced short skating performance and isokinetic strength, where the muscle contracts and shortens at a constant rate of speed.
Isokinetic muscle contraction is the fastest way to increase muscle strength as muscle strengthens uniformly through an entire range of movement.

Another study with volleyball players concluded that EMS combined with plyometric training improved vertical jumping performance
It also showed rapid increases in the muscle strength of knee extensors (muscles that move the knee joint) and plantar flexors (muscles that create movement between the front of the foot and the shin).

The National Strength and Conditioning Association conducted a study to evaluate and quantify the effects of EMS on the cardiorespiratory system, muscle metabolism and perceived exertion on cyclists.
The testing evaluated cycling with EMS vs. cycling without EMS.
The main findings indicated that cycling with EMS could enhance aerobic performance in athletes as well as individuals who are unable to sustain heavy workouts.

The NSCA also conducted a study on the effects of EMS on high performance sports: strength, speed, power, jumping and sprinting ability.
The test group was comprised of untrained subjects, trained athletes and elite athletes.
Scientific analysis showed significant gains and improvements in all areas, in all fitness levels.
Even elite athletes at an already high level of fitness, were able to significantly enhance their performance across the board.
The study concluded that EMS is effective in developing physical performance, and stated that EMS is a “promising alternative to traditional strength training."
The Association’s study into muscle recovery methods on baseball players indicated that EMS is an effective tool for muscle restoration between innings of pitching.
