Effects of Microcurrent Treatment With and Without Resistance Exercises on Body Composition, Muscle Strength, and Physical Function in Middle-aged Adults

What this Trial Is About

Researchers are evaluating the effects of microcurrent treatment alone and combined with a resistance exercise program on muscle strength, body composition, and physical function in middle-aged adults who are not regularly trained. This study uses a randomized, balanced, double-blind design to compare four groups: microcurrent alone, microcurrent with resistance training, sham treatment alone, and sham treatment with resistance training. The goal is to understand how microcurrent therapy may help counteract age-related muscle decline and improve wellbeing in sedentary adults aged 40 to 65. Participants will be assigned to either receive a microcurrent or sham device, and can choose to participate in a supervised resistance training program or be in a non-exercise group. The resistance training involves elastic bands and includes two sessions per week over six weeks, with exercises targeting the whole-body musculature. The microcurrent or sham device will be worn on the dominant upper arm for three hours daily, either after training or in the mornings on non-training days for those exercising, or every morning for non-exercisers. Throughout the study, researchers will measure body composition using plethysmography, muscle thickness with ultrasound, strength, functional capacity, and blood markers related to health and wellbeing before and after the six-week intervention. Participants' exercise intensity will be monitored using a perceived exertion scale. The study will also consider participants' preferences for training in a group setting or at home via video sessions. The total study period includes a familiarization phase followed by 6 weeks of intervention and assessments at baseline and post-intervention.
