Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Single fibers, 25-40 μm wide and 0.5-0.7 mm long, were isolated from the flexor digitorum brevis muscle of the mouse. Force and movement were recorded (21-27°C) from the fiber as a whole and, in certain experiments, from a short marked segment that was held at constant length by feedback control. The maximum tetanic force, 368±57 kN/m (N=10), was not significantly different from that recorded in frog muscle fibers at equal temperature. However, the rising phase of the tetanus was considerably slower in the mammalian fibers, 202±20 ms (N=17) being required to reach 90% of maximum tetanic force as compared with 59±4 ms (N=20) in the frog muscle fibers. Similar to the situation in frog muscle fibers, the force-velocity relation exhibited two distinct curvatures located on either side of a breakpoint near 80% of the isometric force. Maximum speed of shortening was 4.0±0.3 fiber lengths s (N=6). The relationship between tetanic force and sarcomere length was studied between 1.5 and 4.0 μm sarcomere spacings, based on length-clamp recordings that were free of 'tension creep'. There was a flat maximum (plateau) of the length-tension relation between approximately 2.0 and 2.4 μm sarcomere lengths. The descending limb of the length-tension relation (linear regression) intersected the length axis (zero force) at 3.88 μm and reached maximum force at 2.40 μm sarcomere length. The slope of the descending limb is compatible with a thick filament length of 1.63 μm and an average thin filament length of 1.10 μm. These values accord well with recent electron microscope measurements of myofilament length in mammalian muscle.
