Ultrasonography has recently been proposed for assessing changes in thickness and motion of the diaphragm during contraction in humans. Data on ultrasound assessment of abdominal muscles in humans are scarce. We therefore investigated the changes in thickness and the relevant mechanical effects of abdominal muscles using this technique during respiratory manoeuvres in normal subjects. We evalua...

We used electromyography on juvenile American alligators to test the hypothesis that the following muscles, which are known to play a role in respiration, are recruited for aquatic locomotion: M. diaphragmaticus, M. ischiopubis, M. rectus abdominis, M. intercostalis internus, and the M. transversus abdominis. We found no activity with locomotion in the transversus. The diaphragmaticus, ischiopu...

The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Tr...

Muscle injuries generally occur in two-joint muscles with a high percentage of type II fibers during the performance of eccentric activity. Some muscle injuries, such as those located in the adductor longus, a monoarticular muscle, as well as rectus abdominis do not fully comply with these requirements. This study examines five cases of elite handball players with ruptured rectus abdominals. So...

Presentations, research work, GPA, MCAT, extra curriculars, and volunteering. You could call it the “pre-med six-pack,” which, like a well-defined rectus abdominis, represent the “core” of an aspiring young physician. However, unlike one’s abdominal muscles, which experience fatigue after being put through a strenuous workout, these six core components are scheduled for a daily workout in the c...

There is no muscle in the body whose exact anatomy concerns the surgeon so frequently and in so many important ways as does the rectus abdominis. Some operations on the kidney invoke an approach peculiar to that organ, the gallbladder invites attack by an oblique.incision below and parallel to the right costal margin, but with these exceptions, it is safe to say that the majority of major opera...

[Purpose] The purpose of this study was to compare the activity of the shoulder and trunk muscles in two push-up positions: standard push-ups and push-ups with the trunk flexed. [Subjects] Fifteen young adult males participated in the study. [Methods] This study measured the clavicular and sternocostal portions of the pectoralis major, the serratus anterior, and the rectus abdominis during push...
