Abstract
Objective: The aim of the current study was to evaluate the physiological and metabolic responses to running with whole-body electromyostimulation (wbEMS) compared to running without electromyostimulation (control, CG). Methods: Twenty healthy participants (9 male/11 female, age 42 ±7 years) conducted an incremental step test with respiratory gas analysis until exhaustion. Trials were conducted as wbEMS and CG in a random order. As outcome measures, (A) objective total exhaustion, (B) athletic responses (max. time and velocity) and (C) physiological and metabolic responses (V'O2/ kg, V'E, EE, RER, lactate) were compared. (D) The impact on the skeletal muscle was assessed prior, 48 h & 72 h after trial. Results: During both trials, participants (A) ran until total exhaustion. Nonetheless, (B) time and velocity till exhaustion as well as (C) RER prior to the first lactate threshold and V'E were reduced with wbEMS. All other correlates did not differ significantly between wbEMS and CG. Following 48 h and 72 h after the trial with wbEMS, (D) the impact on the skeletal muscle was 7- to 9-fold higher compared to baseline values. Values differed significantly to those after running without wbEMS. Conclusion: With the additional stimulation during voluntary activation, wbEMS induces earlier fatigue and a shift in energy metabolism toward fat utilization. Even during aerobic endurance tasks, a great impact on the skeletal muscle indicated by the rise in CK could be observed which promotes wbEMS as an alternative training stimulus that is easy-to-apply and effective during endurance training.

Abstract
BACKGROUND Electrical muscle stimulation (EMS) activates muscles through electrical currents, resulting in involuntary muscle contractions. This study aimed to evaluate the immediate clinical effects of superimposing EMS on strength training compared with conventional exercise in healthy non-athletic adults. METHODS This study was a randomised, controlled, parallel-group trial conducted at a single centre. Forty-one healthy young volunteers were recruited and randomised into two groups: strengthening with superimposed EMS (S+E) and strengthening (S) groups. All participants underwent the 30 minutes of strength training program, three times a week for 8 weeks, consisting of core muscle exercises. Additionally, the S+E group received EMS during training, which stimulated the bilateral abdominal, gluteus, and hip adductor muscles. As the primary outcome measure, we evaluated the changes in muscle thickness, including the abdominal, gluteal, and hip adductor muscles, using ultrasound. Muscle thickness was measured in both resting and contracted states. For secondary outcomes, physical performance (Functional Movement System score, McGill's core stability test, and hip muscle power) and body composition analysis were evaluated. All assessments were performed at the beginning and end of the intervention. RESULTS 39 participants (S+E group = 20, S group = 19) completed the study. The clinical characteristics and baseline functional status of each group did not differ significantly between the groups. After completion of the training, the S+E group showed more efficient contraction in most of the evaluated muscles. The resting muscle thickness did not differ significantly between the groups; however, the contracted muscle thickness in the S+E group was higher than that in the S group (p < 0.05). Physical performance and body composition were not significantly different between the two groups. No intervention-related complications were reported during the study. CONCLUSION EMS seems to be a safe and reasonable modality for improving physical fitness in healthy individuals.

Abstract
Electromyostimulation (EMS) is a widely used therapeutic tool of low-frequency electrotherapy in several areas of rehabilitation, with gradual use increasingly in sports as well. The main goal of our article is to approach the use of EMS in sports based on available studies. EMS can be called as a training method used to obtain muscle activation through externally applied electric currents to the muscles to achieve a functional increase in sports performance by training fast motor units. Even if, based on the available study database, there are no clear conclusions regarding the effectiveness and application of EMS in the sense of sports, we can say that EMS represents one of the means by which we can influence muscle functionality, not only in terms of rehabilitation, but also as a possible way of increasing sports performance.

Abstract
Pulmonary rehabilitation (PR) is an essential method for Acute exacerbation in chronic obstructive pulmonary disease (AECOPD) recovery. We perform a meta-analysis to compare early PR with usual care. A literature search was performed through these databases: PubMed, MEDLINE database, Google Scholar, Cochrane, Embase from inception to July 2021. Eligible trials were clinical randomized controlled trials comparing the effects of early PR and usual care in AECOPD patients. The primary endpoint of this meta-analysis was FEV1% predicted, 6-min walk test (6MWD), modified Medical Research Council (mMRC) and George Respiratory Questionnaire-total (SGRQ-total). The secondary outcomes were borg dyspnea score, short-form 36 health survey questionnaire physical (SF-36 physical) and SF-36 mental. We included 13 RCTs with a total of 866 patients. There were no significant effects of the PR group on measures of FEV1% predicted (MD = 0.50, 95%CI -1.43 to 2.44, Z = 0.51, p = 0.61), borg dyspnea score (MD = -0.88, 95%CI -1.89 to 0.13, Z = 1.71, p = 0.09) and SF-36 mental (MD = 4.34, 95%CI -1.64 to 10.32, Z = 1.42, p = 0.16) compared with usual care. PR group achieved better 6MWD (MD = 97.58, 95%CI 17.21 to 177.96, Z = 2.38, p = 0.02), mMRC (MD = -0.36, 95%CI -0.52 to -0.21, Z = 4.56, p ˂ 0.00001), SGRQ-total (MD= -9.67, 95%CI -16.23 to -3.11, Z = 2.89, p = 0.004) and SF-36 physical (MD = 4.98, 95%CI 0.60 to 9.35, Z = 2.23, p = 0.03) compared with usual care group. Early PR in AECOPD patients would lead to better 6MWD, mMRC, SGRQ-total and SF-36 physical. But there were no significant effects of the PR group on measures of FEV1% predicted, borg dyspnea score and SF-36 mental.
