PurposeThe aponeurosis, a sheet of fibrous tissue, is the deep and superficial fascia where muscle fibers attach in pennate muscles. It is quite possible that the aponeurosis size increases in response to resistance training-induced fiber hypertrophy due to an increase in connection area. As a result, it leads to an increase in anatomical muscle cr...

Background Swallowing disorders (dysphagia) occur in a large proportion of individuals over the age of 60. The improvement of tongue strength by resistance exercise is postulated to be directly related to lingual‐palatal pressure generation and bolus propulsion into the pharynx during swallowing. To the best of our knowledge, however, there is no e...

Background/objective Roller massage has become a popular intervention in sports settings in order to treat muscle soreness and stiffness, as well as improving post-exercise recovery, although there is limited evidence for these assumptions. Therefore, the purpose of this study was to evaluate the effects of a single session of roller massage, appli...

Background: There is some evidence showing significant correlations between acute chewing gum and orofacial function, and between acute chewing gum and cognitive function; however, as far as we are aware, little is known about the chronic effects of chewing gum training on cognitive and orofacial functions in healthy adults.

Howeve...

Gastric surgery-induced body fat loss automatically reduces fat-free mass (FFM) by changing the fat-free component of adipose tissue. A recent study first reported a change in fat fraction percentage of adipose tissue during gastric bypass surgery-induced weight loss, using chemical shift-based water/fat separation method. Our proposed models showe...
