“…These findings are in concordance with some previous studies observing that WB-EMS increases the maximum dynamic and isometric strength in older individuals [21,23,24,28,29]. It must be pointed that the study cohort is, on average, 10 years younger than the mentioned previous studies, but we consider mentioning them as a probe to show that WB-EMS might seem to be a suitable method to improve the explosive strength component despite the age component [31].…”

Menopause is associated with losses in strength and power along with weight and fat mass gains, which may result from menopause-related hormonal changes, aging-associated diseases, and decreased physical activity time. The objective of this study is to analyze if whole-body electromyostimulation (WB-EMS) is suitable for the prevention and treatment of postmenopausal physical deterioration. Thirty-four healthy sedentary women between 55 and 69 years followed an experimental design pre-post test. Both groups conducted 10 weeks of aerobic and strength training program. The experimental group conducted the training with superimposed WB-EMS during exercise. At the end of the intervention, the experimental group obtained better power (Squat: mean difference (MD) = 38.69 W [1.75,75.62], d = 0.81; Bench press: MD = 25.64 W [17.48, 33.82], d = 2.39) and velocity (Squat: MD = 0.04 m·s−1 [0.01, 0.08], d = 0.98; Bench press: MD = 0.10 m·s−1 [0.06, 0.14], d = 1.90) score improvements than the other group (pBonferroni < 0.05). Furthermore, trivial to small effects were found in the body composition of the participants of both groups (p > 0.050). WB-EMS showed a favorable isolated effect on the development of power and velocity, but it induced negligible effects on the body composition of postmenopausal women.

“…(4) From a practical application point of view, our results provided further evidence that programs that focus on sarcopenia prophylaxis (…or at least its dynamopenic aspect) in men should be started in the 5th decade. Of importance, a related study that focused on trainability in different periods of life (Von Stengel and Kemmler, 2018 ) 10 reported a significant trainability of MIES and MIFS in all the age groups addressed here. This included our oldest cohort of men 80 years+, an observation confirmed by various longitudinal studies (review in Stewart et al, 2014 ).…”

Age-related loss of muscle mass and function, also called sarcopenia, was recently added to the ICD-10 as an independent condition. However, declines in muscle mass and function are inevitable during the adulthood aging process. Concerning muscle strength as a crucial aspect of muscle function, maximum knee extension strength might be the most important physical parameter for independent living in the community. In this study, we aimed to determine the age-related decline in maximum isokinetic knee extension (MIES) and flexion strength (MIFS) in adult men. The primary study hypothesis was that there is a slight gradual decrease of MIES up to ≈age 60 years with a significant acceleration of decline after this “changepoint.” We used a closed kinetic chain system (leg-press), which is seen as providing functionally more relevant results on maximum strength, to determine changes in maximum isokinetic hip/leg extensor (MIES) and flexor strength (MIFS) during adulthood in men. Apart from average annual changes, we aimed to identify whether the decline in maximum lower extremity strength is linear. MIES and MIFS data determined by an isokinetic leg-press of 362 non-athletic, healthy, and community-dwelling men 19–91 years old were included in the analysis. A changepoint analysis was conducted based on a multiple regression analysis adjusted for selected co-variables that might confound the proper relationship between age and maximum strength. In summary, maximum isokinetic leg-strength decline during adulthood averaged around 0.8–1.0% p.a.; however, the reduction was far from linear. MIES demonstrated a non-significant reduction of 5.2 N/p.a. (≈0.15% p.a.) up to the estimated breakpoint of 52.0 years and an accelerated loss of 44.0 N/p.a. (≈1.3% p.a.; p < 0.001). In parallel, the decline in MIFS (10.0 N/p.a.; ≈0.5% p.a.) prior to the breakpoint at age 59.0 years was significantly more pronounced. Nevertheless, we observed a further marked accelerated loss of MIFS (25.0 N/p.a.; ≈1.3% p.a.) in men ≥60 years. Apart from the “normative value” and closed kinetic chain aspect of this study, the practical application of our results suggests that sarcopenia prophylaxis in men should be started in the 5th decade in order to address the accelerated muscle decline of advanced age.

“…Groups were different at baseline for age, which could have influenced the results observed in this study. In our opinion, given the experimental group was slightly older, it could have prejudiced its adaptations reducing the isolate effects of WB-EMS as it is established [31]. Finally, to estimate the maximum intensity at which the participants could be electrostimulated, a pain threshold test was performed.…”

“…Previous studies analyzed the effects of WB-EMS on the health of elders finding improvements in cardiometabolic risk and sarcopenia [23][24][25][26][27][28][29]. Besides, in young people, the WB-EMS has established itself as an effective method of physical conditioning, achieving improvements in VO2max, aerobic threshold, anaerobic threshold, and running economy [30] and in the maximum isometric strength of leg extenders, vertical jump, and strength hand grip [21,24,25,[29][30][31].…”

Whole-body electromyostiulation (WB-EMS) has experienced a boom in recent years, even though its effectiveness is controversial. A sedentary lifestyle is deeply rooted in the European population, mainly in the elderly. This experimental study analyzed the impact of WB-EMS on the physical fitness of postmenopausal women. Thirty-four healthy sedentary women between 55 and 69 years followed an experimental design pre–post-test. Both groups conducted a ten-week aerobic and strength training program. The experimental group overlaid the WB-EMS during exercise. At the end of the intervention, both groups improved upper and lower body strength, lower extremity flexibility, agility, and speed levels (pBonferroni < 0.05). Significant interactions were observed at upper and lower body strength, agility, speed, and cardiovascular endurance (p < 0.05). The WB-EMS group scored better agility than the control group at the end of the intervention (pBonferroni < 0.05) and was the only group that improved cardiovascular endurance. WB-EMS shows a favorable isolate effect on the development of dynamic leg strength, agility, and cardiovascular endurance but did not in dynamic arm strength, gait speed, balance, or flexibility of postmenopausal women.
