Sentence examples for contraction activity from inspiring English sources

This allows for a slow lowering of the body through eccentric (lengthening muscle contraction) activity of the calf muscles.

The data were remarkably consistent across the three cohorts tested, and control trials showed that the methods used to measure heart and abdominal contraction activity did not significantly affect normal physiological functions.

In particular, the lactate threshold is a well known feature of muscle physiology, whereby muscle cells switch to partial anaerobic glucose catabolism when their contraction activity, and their corresponding ATP demand for converting chemical energy to mechanical work exceeds certain intensity [10], [11], even when oxygen abundance is not a limiting factor [12], [13], [14].

Disease cells exhibited enhanced collagen contraction activity compared to control cells.

Sequential redox changes are coupled to muscle contraction activity and disruption of redox equilibria is observed in diverse muscle diseases.

At Phase IV, spike potential activity and contraction activity rapidly declined, but the starting potentials loaded with action potentials still accounted for >5% of the total starting potentials.

In the past, ratios of local to global muscle activity were only analysed in specific isolated local muscle contraction tasks (abdominal drawing in manoeuvre) [ 20] and general movement and isometric contraction activities (flexion, extension and lateral flexion from a semiseated position in an apparatus) [ 21].

Aim of the study was the quantification of co-contraction activity between quadriceps femoris (QF) and hamstring muscles during walking in healthy children.

The number of macrophages within myofibers in this study was considerably lower than previously described after chronic stretch-shortening contractions, activity that produced considerably more injury and functional losses [ 24, 43], indicating we have subdegenerative changes only.

In addition to reduced rhythmicity and a longer circadian period, some aged flies show an unstable phase, which manifests as an expansion and contraction of activity duration: a daily shortening of the duration of activity (alpha) is followed by expanded activity (expansion of alpha) on days 4 6.

The purpose of this study was to investigate the relative (% of maximal voluntary isometric contraction) muscle activity and ratios of local to global muscle activity during single bridging stabilization exercises, ball bridging exercises and bridging exercises with leg movements.
