the purpose of this study was to estimate the torque from high‑density surface electromyography signals of biceps brachii, brachioradialis, and the medial and lateral heads of triceps brachii muscles during moderate‑to‑high isometric elbow flexion‑extension. the elbow torque was estimated in two following steps: first, surface electromyography (emg) amplitudes were estimated using principal com...

We present new explicit tight and overtwisted contact structures on the (round) 3-sphere (flat) 3-torus for which ambient metric is weakly compatible. Our proofs are based construction of nonvanishing curl eigenfields using suitable families Jacobi or trigonometric polynomials. As a consequence, we show that sphere theorem Etnyre, Komendarczyk Massot (2012) does not hold compatible as it was co...

objectives: it is well known that neuromuscular function is temperature sensitive. changing of muscle temperature can effect voluntary muscle contraction. the aim of this study was to investigate the effects of cooling and heating on maximal isometric force generated by the elbow flexor musculature in male subjects. methods: forty five healthy males encompassing 3 groups participated in the cur...

muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...

objective: effect of peppermint on exercise performance was previously investigated but equivocal findings exist. this study aimed to investigate the effects of peppermint ingestion on the physiological parameters and exercise performance after 5 min and 1 h. materials and methods: thirty healthy male university students were randomly divided into experimental (n=15) and control (n=15) groups. ...

this study describes length-weight relationships of five species (platycephalus indicus, pseudorhombus elevates, plicofollis tenuispinis, grammoplites suppositus, pomadays stridens) collected from persian gulf (khuzestan province, iran) during december 2009 to november 2011. a total of 2065 specimen were examined for this study. the relationship between weight and total length were estimated: w...

The purpose of this study was to measure treatment outcomes in a group of six adults with chronic dysphagia following acquired brain injury, who each completed 24 sessions of tongue-pressure resistance training, over a total of 11-12 weeks. The treatment protocol emphasized both strength and accuracy. Biofeedback was provided using the Iowa Oral Performance Instrument. Amplitude accuracy target...
