Abstract
A rehabilitative program for patients who lose strength and muscle mass along with the ability to perform intensive exercises is lacking. We developed a 3-week training program based on neuromuscular electrical stimulation (NMES) using a RSQ1 device (modulated current resulting from the overlapping of two-component currents) for RSQ1 electrostimulation to improve strength parameters of the quadricep femoris muscles and compare its effectiveness to isometric training. Nineteen university students were randomly divided into the NMES group (10 sessions) and the control group who trained. We measured the circumference of the thigh, as well as peak torques of the flexor and extensor muscles before and after the start and after the end of the training program. Both tested training programs gave similar results. Differences between measured parameters were not significant except for differences in the peak torques of the knee flexors (9.9% for left limb; p = 0.2135 vs. 7.8% for rift limb; p = 0.2135) and the circumference of the left thigh—2% for both (left p = 0.5839 and right p = 0.1088). Comparable results of the tested training programs suggest that NMES is a good alternative for people who cannot perform exercises, but want to maintain or improve their physical fitness.

In the 21st century, technological progress in medicine and physiotherapy, as well as the holistic approach to patients and athletes, have created new opportunities for rehabilitation and training [1,2]
Kemmler et al [7], in their randomised controlled study, showed that neuromuscular electrical stimulation (NMES) sessions correspond to four times longer training with high-intensity exercises
The aim of this study was to develop a 3-week training program based on NMES using RSQ1 electrostimulation to improve strength parameters of the quadricep femoris muscles in university students, and to compare its effectiveness to classical strength training
Summary
In the 21st century, technological progress in medicine and physiotherapy, as well as the holistic approach to patients and athletes, have created new opportunities for rehabilitation and training [1,2]. Electrical muscle stimulation (EMS) treatments, in addition to their wide application in rehabilitation, are more and more often used in training sessions to diversify strength exercises or as an alternative for people who want to maintain physical fitness but do not have time or opportunities for standard training in the gym [3,4,5,6,7]. Kemmler et al [7], in their randomised controlled study, showed that neuromuscular electrical stimulation (NMES) sessions correspond to four times longer training with high-intensity exercises. After the use of NMES, jumping ability is improved [8] and maximum muscle strength is increased [9].
