Effects of EMS on Vertical Jump Height

A study investigated the influence of a 4-week EMS, or electrical muscle stimulation, training program on the strength of the knee extensors and the vertical jump performance of 10 basketball players.

EMS sessions were used 3 times weekly; each session consisted of 48 contractions.

Testing was carried out before and after the EMS training program (week 4) and once more after 4 weeks of normal basketball training (week 8).

At week 4, isokinetic strength increased significantly (p < 0.05) at eccentric and high concentric velocities between 180 and 360 x s(-1); this was not the case for low concentric velocities (60 and 120 degreess (-1).

EMS training increased also isometric strength at the two angles adjacent to the training angle (p < 0.01). Squat jump increased significantly by 14% at week 4 (p < 0.01), counter movement-jump showed no change.

At week 8, gains in isokinetic, isometric strength and squat-jump performance were maintained and the counter movement jump performance increased significantly by 17% (p<0.01).

EMS as part of a short strength-training program enhanced knee extensor strength and squat jump performance of basketball players.

(Electric Muscle Stimulation)

Electric Muscle Stimulation, or EMS, is a revolutionary muscle exercise concept for use now in your home, office or on the go.

Electrical muscle stimulation works by sending safe, gentle, electronic impulses to contract muscles.

This electric stimulation is similar to the message the central nervous system sends causing muscles to contract during a workout. The electronic impulses travel from the EMS unit, through lead wires to self-adhesive electrodes, or rubber electrodes that adhere to the skin above the muscle.

EMS is a tool for toning, strengthening and building muscles, rehabilitation of muscles, and pain management. Physical therapists, chiropractic doctors, and professional athletes have used EMS devices for many years.

Now with over-the-counter EMS devices, the general public is enjoying the benefits of Electric Muscle Stimulation as well.
