In many medical fields the recovery of muscular activity or its improvement up to the level of the optimal parameters is required. Apart from the classical solution for rehabilitation (physical exercises) the use of electrical stimulation has become quite frequent of late. The paper presents an interface that detects the electromyographic (EMG) activity, assesses it, and generates appropriate electrical stimuli, by means of a specific type of fuzzy control system, in order to control the dynamics of the EMG. The proposed interface will detect the motion and muscular activity, it will evaluate and generate the electrical stimulus using a fuzzy system tuned by dynamic of motion. The application will transmit e-Health information to the physician via Internet, synthetic, at request using TCP/IP stack and SMS services for wireless communication.

Blood flow restriction exercise (BFRE) is a therapeutic approach traditionally used to facilitate muscular strength and hypertrophy. Emerging evidence has identified its benefits on other systems and metabolic processes. The emphasis of this study was to examine potential impact of BFRE on serum levels of tissue plasminogen activator (tPA).

Background: Muscle diseases are serious challenges to human health. Prokineticin receptor 1 (PROKR1) has emerged as a potential target to improve muscle function through increasing oxidative muscle fibres, but there are no clinically applicable synthetic PROKR1 agonists.
Methods: Drugs with biological properties of prokineticin 2 (PK2) were discovered through connectivity map (CMap) analysis.

This study aimed to examine the acute effects of concurrent muscle strength and sport-specific endurance exercise order on immunological stress responses, metabolic response, muscular-fitness, and rating-of-perceived-exertion (RPE) in highly trained youth female judo athletes. Thirteen female participants randomly performed two concurrent training (CT) sessions; strength-endurance and endurance-strength. Immune response, metabolic response, muscular fitness (i.

During a sustained high-intensity isometric maximal voluntary contraction (MVC), declining motor unit firing rates (MUFRs) accompany torque loss. This decline (∼50% over 60 s) helps to maintain torque by preserving peripheral electrical propagation and matching the slowing contractile properties with torque loss (i.e.

This study examined how successive sets of high-intensity leg press (LP) resistance exercise impact the cerebral pressure-flow relationship in untrained males and eumenorrheic females not taking oral contraceptives, and assessed how menstrual cycle (MC) phase influences the cerebral pressure-flow relationship and cerebral hemodynamics (middle cerebral artery blood velocity; MCAv; via transcranial Doppler ultrasound) during and after LP exercise in females. Young adults (11M;11F) performed three sets of leg-press exercises at 90% of their 1-repetition maximum. Data from males and females in early follicular phase were pooled together.
